Fixed- and Adjustable-Rate Loan Schedule. The following table sets forth our fixed- and adjustable-rate loans at December 31, 20192020 that are contractually due after December 31, 2020.2021.

Loan Approval Procedures and Authority. Pursuant to federal law, the aggregate amount of loans that Cincinnati Federal is permitted to make to any one borrower or a group of related borrowers is generally limited to 15% of Cincinnati Federal’s unimpaired capital and surplus (25% if the amount in excess of 15% is secured by “readily marketable collateral” or 30% for certain residential development loans). At December 31, 2019,2020, based on the 15% limitation, Cincinnati Federal’s loans-to-one-borrower limit was approximately $3.7$5.5 million. On the same date, Cincinnati Federal had no borrowers with outstanding balances in excess of this amount. At December 31, 2019,2020, our largest loan relationship with one borrower was for approximately $2.7$3.3 million, secured by a nonresidentialmultifamily property, and was performing in accordance with its original terms on that date.

Our lending is subject to written underwriting standards and origination procedures. Decisions on loan applications are made on the basis of detailed applications submitted by the prospective borrower, credit histories that we obtain, and property valuations (consistent with our appraisal policy) prepared by outside independent licensed appraisers approved by our board of directors as well as internal evaluations, where permitted by regulations. The loan applications are designed primarily to determine the borrower’s ability to repay the requested loan, and the more significant items on the application are verified through use of credit reports, bank statements and tax returns. We generally follow underwriting procedures that are consistent with Freddie Mac underwriting guidelines.

Under our loan policy, the loan underwriter of an application is responsible for ensuring proposals and approval of any extensions of credit are in compliance with internal policies and procedures and applicable laws and regulations, and for establishing and maintaining credit files and documentation sufficient to support the loan and to perfect any collateral position. Loans originated for sale may be approved by any loan underwriter, if the loan conforms to the underwriting guidelines established by the investor to whom the loan will be sold.

Loans to be held in our portfolio may not be approved solely by an underwriter, and generally require review and approval by our Chief Lending Officer, members of the loan committee or the board of directors. All loan approval amounts are based on the aggregate loans, including total balances of outstanding loans and the proposed loan to the individual borrower and any related entity. For one- to four-family owner-occupied real estate loans, our Chief Lending Officer, any two members of the loan committee or any one loan committee member and one underwriter are authorized to approve loans up to $424,100 in the aggregate.

For one- to four-family owner-occupied real estate, non-owner occupied one- to four-family owner-occupied real estate, commercial real estate, undeveloped lots or employee loans, any three members of the loan committee are authorized to approve up to $750,000 in the aggregate. The entire loan committee may approve loans up to $1,000,000 in the aggregate. For aggregate loans in excess of $1,000,000, approval of the board of directors is required.

For all other loans, our Chief Lending Officer or any two members of the loan committee are authorized to approve aggregate loans up to $50,000, with three loan committee members able to approve aggregate loans up to $250,000. As above, the approval of the full loan committee is required for loans up to $1,000,000 and approval of the board of directors is required for loans in excess of $1,000,000.

Generally, we require title insurance or abstracts on our mortgage loans as well as fire and extended coverage casualty insurance in amounts at least equal to the principal amount of the loan or the value of improvements on the property, depending on the type of loan.

One- to Four-Family Residential Real Estate Lending. The focus of our lending program has historically been the origination of one- to four-family residential real estate loans. At December 31, 2019,2020, we had $104.8$84.8 million of loans secured by one- to four-family real estate, representing 57.7%49.0% of our total loan portfolio. We originate both fixed- and adjustable-rate residential mortgage loans. At December 31, 2019,2020, the one- to four-family residential mortgage loans held in our portfolio due after December 31, 2020 were comprised of 20.7%35.7% fixed-rate loans, and 79.3%64.3% adjustable-rate loans.

Prior to 2010, we engaged in significant non-owner occupied one- to four-family real estate lending. Many of these loans were made to investors who owned a number of rental properties, and which did not provide sufficient rental cash flows to service the repayment of the loans. There is a greater credit risk inherent in non-owner occupied properties, than in owner occupied properties since, like nonresidential real estate and multi-family loans, the repayment of these loans may depend, in part, on the successful management of the property and/or the borrower’s ability to lease the property. A downturn in the real estate market or the local economy could adversely affect the value of properties securing these loans or the revenues derived from these properties which could affect the borrower’s ability to repay the loan. Beginning with the economic downturn that began in 2008, we experienced higher levels of delinquencies and charge-offs in our non-owner occupied residential loan portfolio. Our management took steps to reduce our delinquent and non-performing assets in this portfolio, and to reduce this type of lending. See “—Delinquencies and Non-Performing Assets” below. At December 31, 2019,2020, we had $12.8$12.1 million of non-owner occupied residential loans.

We currently originate a small number of non-owner occupied residential loans. Non-owner occupied loans as a percentage of total loans have decreased to 7.1% at December 31, 2019 from 8.2% at December 31, 2018.was 7.0%. We impose strict underwriting guidelines in the origination of such loans, including a maximum number of loans to the same borrower, local residency, and no prior bankruptcies and/or foreclosures. Properties securing non-owner occupied loans must be within 50 miles of a Cincinnati Federal branch office. We also generally limit loans on non-owner occupied properties to borrowers with no more than ten total rental properties as a way to mitigate the risks involved in lending to professional property investors.

Our one- to four-family residential real estate loans are generally underwritten according to Fannie Mae and Freddie Mac guidelines, and we refer to loans that conform to such guidelines as “conforming loans.” We generally originate both fixed- and adjustable-rate mortgage loans in amounts up to the maximum conforming loan limits as established by the Federal Housing Finance Agency for Fannie Mae. We also originate loans above the lending limit for conforming loans, which are referred to as “jumbo loans.” We also offer FHA, VA and Rural Housing Development loans, all of which we originate for sale on a servicing-released, non-recourse basis in accordance with FHA, VA and USDA guidelines. We use an underwriter with expertise in FHA/VA lending. With the exception of three residential loans totaling $953,000 at December 31, 2019, all of our one- to four-family residential real estate loans at that date are secured by properties located in our market area.

We generally limit the loan-to-value ratios of our owner-occupied one- to four-family residential mortgage loans to 85% of the purchase price or appraised value, whichever is lower. In addition, we may make one- to four-family residential mortgage loans with loan-to-value ratios up to 95% of the purchase price or appraised value, whichever is less, if the borrower obtains private mortgage insurance. Non-owner occupied one- to four-family residential mortgage loans are limited to an 80% loan-to-value ratio.

Our one- to four-family residential real estate loans typically have terms of up to 30 years, with non-owner occupied loans limited to a maximum term of 25 years. Our adjustable-rate one- to four-family residential real estate loans generally have fixed rates for initial terms of three, five or seven years, and adjust annually thereafter at a margin. In recent years, this margin has been between 2.75% and 3.25% over the weekly average yield on U.S. treasury securities adjusted to a constant maturity of one year. The maximum amount by which the interest rate may be increased or decreased is generally 2% per adjustment period and the lifetime interest rate cap is generally 6% over the initial interest rate of the loan.

Although adjustable-rate mortgage loans may reduce to an extent our vulnerability to changes in market interest rates because they periodically re-price, as interest rates increase, the required payments due from the borrower also increase (subject to rate caps), increasing the potential for default by the borrower. At the same time, the ability of the borrower to repay the loan and the marketability of the underlying collateral may be adversely affected by higher interest rates. Upward adjustments of the contractual interest rate are also limited by the maximum periodic and lifetime rate adjustments permitted by our loan documents. Moreover, the interest rates on most of our adjustable-rate loans do not adjust for a period ranging from three years up to seven years after origination. As a result, the effectiveness of adjustable-rate mortgage loans in compensating for changes in general interest rates may be limited during periods of rapidly rising interest rates.

We also originate home equity lines of credit and fixed-term home equity loans. See “—Home Equity Loans and Lines of Credit.”

We do not offer “interest only” mortgage loans on permanent one- to four-family residential real estate loans (where the borrower pays interest for an initial period, after which the loan converts to a fully amortizing loan). We also do not offer loans that provide for negative amortization of principal, such as “Option ARM” loans, where the borrower can pay less than the interest owed on the loan, resulting in an increased principal balance during the life of the loan. We do not offer “subprime loans” on one- to four-family residential real estate loans (i.e., generally loans with credit scores less than 660), except for loans originated for sale in the secondary market.

We currently offer a special residential mortgage program with preferred loan terms to new and existing medical physicians. This program includes (i) preferred treatment of new physician income with regard to positions offered or recently begun and (ii) mortgage loans with a loan-to-value ratio up to 95% to 100% without the need to obtain mortgage insurance for loans up to $600,000. Doctors licensed for at least one year or self-employed for at least two years may receive mortgage loans with loan-to-value ratios up to 90% to 100% without the need to obtain mortgage insurance for loans up to $700,000 and 85% for loans greater than $700,000. The portfolio of loans originated under this program was $8.2$4.6 million as of December 31, 2019.2020.

Nonresidential Real Estate and Multi-Family Lending. In recent years, we have increased our nonresidential real estate and multi-family loans. Our nonresidential real estate loans are secured primarily by office buildings, retail and mixed-use properties, and light industrial properties located in our primary market area. Our multi-family loans are secured primarily by apartment buildings. At December 31, 2019,2020, we had $23.4$29.5 million in nonresidential real estate loans and $36.6$41.7 million in multi-family real estate loans, representing 12.9%17.1% and 20.2%24.2% of our total loan portfolio, respectively.

Most of our nonresidential and multi-family real estate loans have a maximum term of up to 25 years. The interest rates on nonresidential real estate and multi-family loans are generally fixed for an initial period of three, five or seven years and adjust annually thereafter based on the One Year Treasury Rate. The maximum loan-to-value ratio of our nonresidential real estate loans is generally 75% while multi-family real estate loans have a maximum loan-to-value ratio of 80%. All loan-to-value ratios are subject to our underwriting procedures and guidelines. At December 31, 2019,2020, our largest nonresidential real estate loan totaled $2.7$3.2 million and was secured by retail property.an industrial use facility. At that date, our largest multi-family real estate loan totaled $2.5$3.3 million and was secured by an apartment building. At December 31, 2019,2020, both of these loans were performing in accordance with their original terms. Set forth below is information regarding our nonresidential real estate loans at December 31, 2019.2020.

We consider a number of factors in originating nonresidential and multi-family real estate loans. We evaluate the qualifications and financial condition of the borrower, including credit history, profitability and expertise, as well as the value and condition of the property securing the loan. When evaluating the qualifications of the borrower, we consider the financial resources of the borrower, the borrower’s experience in owning or managing similar property and the borrower’s payment history with us and other financial institutions. In evaluating the property securing the loan, the factors we consider include the net operating income of the mortgaged property before debt service and depreciation, the ratio of the loan amount to the appraised value of the mortgaged property and the debt service coverage ratio (the ratio of net operating income to debt service). All nonresidential real estate and multi-family loans are appraised by outside independent appraisers approved by the board of directors. Personal guarantees are generally obtained from the principals of nonresidential and multi-family real estate borrowers.

Loans secured by nonresidential and multi-family real estate generally are larger than one- to four-family residential loans and involve greater credit risk. Nonresidential real estate loans often involve large loan balances to single borrowers or groups of related borrowers. This greater risk is due to several factors, including the concentration of principal in a limited number of loans and borrowers, the effects of general economic conditions on income-producing properties and the increased difficulty of evaluating and monitoring these types of loans. Repayment of nonresidential real estate loans depends to a large degree on the results of operations and management of the properties securing the loans or the businesses conducted on such property, and may be affected to a greater extent by adverse conditions in the real estate market or the economy in general. Furthermore, the repayment of loans secured by multi-family residential real estate is typically dependent upon the successful operation of the related real estate project. If the cash flow from the project is reduced (for example, if leases are not obtained or renewed), the borrower’s ability to repay the loan may be impaired. Accordingly, the nature of these loans makes them more difficult for management to monitor and evaluate. At December 31, 2019,2020, we had no non-performing nonresidential or multifamily real estate loans.

Construction Lending and Land Loans. We make construction loans to individuals for the construction of their primary residences and, to a limited extent, loans to builders and commercial borrowers. We also make a limited amount of land loans to complement our construction lending activities, as such loans are generally secured by lots that will be used for residential development. Land loans also include loans secured by land purchased for investment purposes. At December 31, 2019,2020, our construction loans, including land loans, totaled $5.3$5.8 million, representing 2.9%3.4% of our total loan portfolio.

Loans to individuals for the construction of their residences are typically originated as construction/permanent loans, with a construction phase for up to 18 months. Upon completion of the construction phase, the loan automatically becomes a permanent loan. These construction loans have rates and terms comparable to one- to four-family residential loans offered by us. During the construction phase, the borrower pays interest only. The maximum loan-to-value ratio of owner-occupied single-family construction loans is generally 80%, or higher if mortgage insurance is obtained. Residential construction loans are generally underwritten pursuant to the same guidelines used for originating permanent residential loans. Land loans are generally offered for terms of up to 5 years. The maximum loan-to-value ratio of land loans is 65% for developed lots and 50% for undeveloped land loans.

At December 31, 2019,2020, our largest outstanding residential construction loan was for $560,000$804,000 of which $546,300$94,000 was outstanding. This loan was performing according to its original terms at December 31, 2019.2020. At December 31, 2019,2020, there were no residential construction loans that were 60 days or more delinquent.

Loans to builders for the construction of pre-sold and market (not pre-sold) homes typically run for up to 24 months. These construction loans have rates and terms comparable to one- to four-family residential loans offered by us. The maximum loan-to-value ratio of pre-sold builder construction loans is generally 80%, and this ratio is reduced to 65% on market homes. Construction loans to builders require that financial statements and tax returns be supplied and reviewed annually. Additionally, we limit construction loans to builders, to no more than two loans on market homes in one development at a time, or no more than one loan per builder at a time.

Loans for the construction of nonresidential or multi-family properties typically run for up to 18 months. These construction loans have rates and terms comparable to nonresidential real estate loans offered by us. The maximum loan-to-value ratio of nonresidential or multi-family construction loans is generally 75%. Nonresidential real estate construction loans also have a 50% pre-leasing requirement. No such requirement is placed on multi-family construction loans.

At December 31, 2019,2020, our largest outstanding nonresidential or multi-family construction loan was $442,000.$1.7 million. This loan was performing in accordance with its original terms at December 31, 2019.2020.

The application process for a construction loan includes a submission to Cincinnati Federal of accurate plans, specifications and costs of the project to be constructed or developed. These items are used as a basis to determine the appraised value of the subject property. Loans are based on the lesser of current appraised value and/or the cost of construction (land plus building). Our construction loan agreements generally provide that loan proceeds are disbursed in increments as construction progresses. Outside independent licensed appraisers inspect the progress of the construction of the dwelling before disbursements are made.

Construction and land lending generally are made for relatively short terms. However, to the extent our construction loans are not made to owner-occupants of single-family homes, they are more vulnerable to changes in economic conditions and the concentration of credit with a limited number of borrowers. Further, the nature of these loans is such that they are more difficult to evaluate and monitor. Our risk of loss on a construction or land loan is dependent largely upon the accuracy of the initial estimate of the property’s value upon completion of the project and the estimated cost (including interest) of the project. If the estimate of value proves to be inaccurate, we may be confronted, at or prior to the maturity of the loan, with a project with a value which is insufficient to assure full repayment and/or the possibility of having to make substantial investments to complete and sell the project. Because defaults in repayment may not occur during the construction period, it may be difficult to identify problem loans at an early stage.

Home Equity Loans and Lines of Credit.We offer home equity loans and lines of credit, which are generally made for owner-occupied homes, and are secured by first or second mortgages on residences. We generally offer these loans with a maximum loan-to-value ratio (including senior liens on the collateral property) of 90% if the first mortgage is originated by Cincinnati Federal and 85% if the first mortgage is not originated by Cincinnati Federal. We currently offer home equity lines of credit for a period of ten years, and generally at rates tied to the prevailing prime interest rate. We also offer home equity lines of credit on non-owner occupied properties, where the first mortgage is also originated by us, with a maximum loan-to-value ratio of 50% for a maximum term of two years. Our home equity loans and lines of credit are generally underwritten in the same manner as our one- to four-family residential loans. At December 31, 2019,2020, we had $10.0$9.9 million of home equity lines of credit and $1.9$2.2 million of fixed-term home equity loans, representing 5.5%5.8% and 1.1%1.3% of our total loan portfolio, respectively. At December 31, 2019,2020, we had oneno home equity linelines of credit that waswere 30 days or more delinquent totaling $98,000.delinquent.

Home equity lines of credit and fixed-term home equity loans have greater risk than one- to four-family residential real estate loans secured by first mortgages. Our interest is generally subordinated to the interest of the institution holding the first mortgage. Even where we hold the first mortgage, we face the risk that the value of the collateral may not be sufficient to compensate us for the amount of the unpaid loan and costs of foreclosure and we may be unsuccessful in recovering the remaining balance from those customers.

Commercial Business Loans. We have generally conducted very limited commercial business lending. We participated in the Paycheck Protection Program (“PPP”) and originated $634,000 in such loans. The board of directors has also authorized management to purchase up to $500,000 in commercial business loans from an unaffiliated commercial lender specializing in loans to physicians and other professionals in the medical field. These are installment loans amortizing over seven years and carry higher interest rates than traditional residential loans. These loans may be secured by liens on non-real estate business assets. These loans are often used for working capital, debt consolidation, equipment and other general business purposes. The loans to be purchased must be reviewed and found to be consistent with our loan policy and underwriting guidelines. As of December 31, 2019,2020, we had acquired such loans in the aggregate amount of $206,000$158,000 or 0.1% of the loan portfolio. At December 31, 2019,2020, the loans were performing in accordance with their original terms.

Consumer Lending. To date, our consumer lending apart from home equity loans and lines of credit has been limited. At December 31, 2019,2020, we had $864,000$339,000 of consumer loans outstanding, representing approximately 0.5%0.2% of our total loan portfolio. Of these loans, $589,000 was secured by investment securities.

Originations, Purchases and Sales of Loans

Lending activities are conducted primarily by our salaried loan personnel operating at our main and branch office locations and by our loan officers. All loans originated by us are underwritten pursuant to our policies and procedures. We originate both fixed- and adjustable-rate loans. Our ability to originate fixed- or adjustable-rate loans is dependent upon relative customer demand for such loans, which is affected by current and expected future levels of market interest rates. We originate real estate and other loans through our loan officers, marketing efforts, our customer base, walk-in customers and referrals from real estate brokers, builders and attorneys.

Consistent with our interest rate risk strategy, we originate for sale and sell the majority of the fixed-rate, one- to four-family residential real estate loans that we originate with terms of greater than 10 years, on a combination of servicing-retained and servicing-released, limited or no recourse basis, while generally retaining shorter-term fixed-rate and all adjustable-rate one- to four-family residential real estate loans in order to manage the duration and time to repricing of our loan portfolio.  Additionally, we consider the current interest rate environment in making decisions as to whether to hold the mortgage loans we originate for investment or to sell such loans to investors, choosing the strategy that is most advantageous to us from a profitability and risk management standpoint. At December 31, 2019,2020, we had $3.1$13.3 million in loans held for sale.

From time to time, we may purchase or sell participation interests in loans. We underwrite our participation portion of the loan according to our own underwriting criteria and procedures. At December 31, 20192020 and December 31, 2018,2019, we had $5.7$4.2 million and $2.7$5.7 million in loan participation interests that we purchased. At those dates, we had $4.2$2.1 million and $2.6$4.2 million in loan participation interests sold.

Historically, we generally do not purchase whole loans or loan participations from third parties to supplement our loan production. However, we have purchased loans from a commercial lender specializing in loans to physicians and other professionalprofessionals in the medical field. We may purchase additional loans from that lender in the future. See “—Commercial Business Loans.”

We generally sell our loans without recourse, except for customary representations and warranties provided in sales transactions. Loan servicing includes collecting and remitting loan payments, accounting for principal and interest, contacting delinquent borrowers, supervising foreclosures and property dispositions in the event of unremedied defaults, making certain insurance and tax payments on behalf of the borrowers and generally administering the loans. We retain a portion of the interest paid by the borrower on the loans we service as consideration for our servicing activities. For the years ended December 31, 20192020 and 2018,2019, we sold $95.5$291.4 million and $54.4$93.8 million of residential loans, respectively, of mortgage loans. Some of the mortgage loans were sold on a servicing-released basis, and we retained servicing on certain of these loans. At December 31, 2019,2020, we serviced $103.9$230.2 million of fixed-rate and adjustable, one- to four-family residential real estate loans that we originated and sold in the secondary market.

The following table sets forth our loan origination, purchase, sale and principal repayment activity during the periods indicated.

Delinquencies and Non-Performing Assets

Delinquency Procedures.Procedures. When a loan payment becomes 20 days past due, we contact the customer by mailing a late notice. If a loan payment becomes 30 days past due, we mail a “right to cure” letter to the borrower and any co-makers and endorsers. If a loan payment becomes 90 days past due (or a borrower misses three consecutive payments, whichever occurs first), we send a demand letter and generally cease accruing interest. It is our policy to institute legal procedures for collection or foreclosure when a loan becomes 120 days past due, unless management determines that it is in the best interest of Cincinnati Federal to work further with the borrower to arrange a workout plan. From time to time we may accept deeds in lieu of foreclosure.

When we acquire real estate as a result of foreclosure, the real estate is classified as real estate owned.  The real estate owned is recorded at the lower of carrying amount or fair value, less estimated costs to sell. Soon after acquisition, we order a new appraisal to determine the current market value of the property. Any excess of the recorded value of the loan satisfied over the market value of the property is charged against the allowance for loan losses, or, if the existing allowance is inadequate, charged to expense of the current period. After acquisition, all costs incurred in maintaining the property are expensed.  Costs relating to the development and improvement of the property, however, are capitalized to the extent of estimated fair value, less estimated costs to sell.

Delinquent Loans. The following tables set forth our loan delinquencies, including nonaccrual loans, by type and amount at the dates indicated.

Classified Assets. Federal regulations provide for the classification of loans and other assets, such as debt and equity securities considered by the Office of the Comptroller of the Currency to be of lesser quality, as “substandard,” “doubtful” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard,” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Assets classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of a specific loss allowance is not warranted. Assets which do not currently expose the insured institution to sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are designated as “special mention” by our management.

When an insured institution classifies problem assets as either substandard or doubtful, it may establish general allowances in an amount deemed prudent by management to cover probable accrued losses. General allowances represent loss allowances which have been established to cover probable accrued losses associated with lending activities, but which, unlike specific allowances, have not been allocated to particular problem assets. When an insured institution classifies problem assets as “loss,” it is required either to establish a specific allowance for losses equal to 100% of that portion of the asset so classified or to charge-off such amount. An institution’s determination as to the classification of its assets and the amount of its valuation allowances is subject to review by the regulatory authorities, which may require the establishment of additional general or specific loss allowances.

In connection with the filing of our periodic reports with the Office of the Comptroller of the Currency and in accordance with our classification of assets policy, we regularly review the problem loans in our portfolio to determine whether any loans require classification in accordance with applicable regulations.

On the basis of this review of our assets, our classified or special mention assets (presented gross of allowance) at the dates indicated were as follows:

Non-Performing Assets.We generally cease accruing interest on our loans when contractual payments of principal or interest have become 90 days delinquent unless the loan is well-secured and in the process of collection. Loans are placed on non-accrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for loans placed on non-accrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until the loansloan qualifies for return to accrual. Generally, loans are restored to accrual status when all the principal and interest amounts contractually due are brought current, and future payments are reasonably assured. Loans are moved to non-accrual status in accordance with our policy, which is typically after 90 days of non-payment.

The following table sets forth information regarding our non-performing assets and troubled debt restructurings. Troubled debt restructurings include loans for which either a portion of interest or principal has been forgiven, or loans modified at interest rates materially less than current market rates.
