NATIONAL PROPERTIES CORPORATION
NOTES TO THE FINANCIAL STATEMENTS

The balance sheet at March 31, 2004, and the statements of income
and comprehensive income and cash flows for the periods ended March
31, 2004, and March 31, 2003, are not audited but reflect all
adjustments which are of a normal recurring nature and are, in the
opinion of management, necessary to a fair statement of the results
of the periods shown.

The Company classifies its existing marketable equity securities as
available-for-sale in accordance with the provisions of Statement
of Financial Standards No. 115, "Accounting for Certain Investments
in Debt and Equity Securities."  These securities are carried at
fair market value, with the increase or decrease in unrealized
gains and losses reported as other comprehensive income or losses
in the statement of income and comprehensive income.  Realized
gains or losses on securities sold are based on the specific
identification method.

Real estate investments acquired or developed by the Company are
not held for resale, but are held as productive assets. When the
Company disposes of a property, it will generally exchange that
property for another productive property. The Company accounts for
these nonmonetary transactions in accordance with Accounting
Principles Board Opinion No. 29 "Accounting for Nonmonetary
Transactions", by recording the property received in the exchange
at the recorded amount of the property surrendered plus any
additional amount paid.  Therefore, no gain or loss is recognized
on the disposed property.

Long Term Debt

The Company has a revolving credit agreement dated February 8,
2001, with Wells Fargo Bank, N.A.  The credit facility permits the
Company to borrow up to $15,000,000.  At March 31, 2004,
$10,975,000 ($11,975,000 at December 31, 2003) was outstanding
under the agreement which matures on April 30, 2006.  The revolving
period of the agreement provides for annual extensions each April
30th at the mutual agreement of the bank and the Company.  It is
the Company's intention to request an extension of the revolving
period, as provided by the agreement.  Advances under the credit
facility bear interest at 0.75% below the bank's base rate.  At
March 31, 2004, the outstanding balance accrued interest at 3.25%.
In addition, the agreement requires the Company to pay an annual
commitment fee of 1/8 of 1% (payable quarterly) on the unused
portion of the line of credit commitment.  The credit agreement
contains various covenants, including limitations on additional
borrowings and maintaining a minimum free cash flow, as defined in
the agreement, of $1,800,000 per year measured as of the end of
each fiscal quarter on an annualized basis.  The Company was in
compliance with all covenants at March 31, 2004.  The line of
credit is secured by first mortgages on nine properties that had a
net book value of approximately $7,400,000 at March 31, 2004.

Item 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
         CONDITION AND RESULTS OF OPERATIONS

General

The Company, an Iowa Corporation, is a lessor of commercial real
estate to tenants under net lease arrangements.  It is the
Company's policy to invest in properties that are fully leased to a
single tenant which is responsible for payment of real estate
taxes, insurance, utilities and repairs.  Under such circumstances,
the Company has limited management responsibilities for such
properties once they are constructed and leased.  In most cases,
properties are constructed by the tenant and conveyed to the
Company under a sale and leaseback arrangement.  It is not the
policy of the Company to invest in multiple tenant office buildings
or residential facilities.  The Company currently owns property
located in Arizona, Colorado, Georgia, Iowa, Kansas, Missouri,
Nebraska, North Carolina, Oklahoma, South Dakota, Tennessee, and
Texas.

Operating Results

During the first quarter 2004, lease revenues increased $62,000 or
4.3% over the same period in 2003.  The increase in lease revenues
for the first quarter of 2004 relative to the first quarter of
2003, was attributed to: (1) the acquisition of a restaurant
property in August 2003 and a drug store property in November 2003,
which in the aggregate, added $141,000 to lease revenue in the
first quarter of 2004, (2) a decrease in lease revenue of $68,000
due to the disposition of two garden center properties in 2003, (3)
a decrease of $19,000 in contingent rents, and (4) an increase in
lease revenues of $8,000 due to escalation clauses in the leases of
some tenants.

The Company recorded investment income, including gains from the
sale of marketable securities of $22,000 in the first quarter of
2004 compared to $17,000 for the first quarter of 2003.  The
Company recorded no property sales in 2004 compared to recording a
gain of $40,000 from a property sale in 2003.

Operating expenses increased $29,000 or 5.4% in the first quarter
of 2004 over the same period in 2003, as a result of increases in
depreciation, interest, and compensation costs.

Depreciation expense increased $20,000 in the first quarter of 2004
over the first quarter of 2003, as a result of property
acquisitions in 2003.

Interest expense increased only slightly in the first quarter 2004
over the same period in 2003 due to a higher average outstanding
loan balance and a slightly lower borrowing cost on the Company's
line of credit.  Average outstanding debt in the first quarter 2004
was $11,488,000 compared to $10,656,000 for the first quarter of
2003.  The interest rate on the Company's revolving line of credit
declined from 3.5% to 3.25% effective July 1, 2003, where it has
remained.  The average interest rate on borrowings in the first
quarter 2004 was 3.30% compared to 3.51% for the first quarter
2003.

Other general and administrative (G & A) expenses increased a net
$9,000 in the first quarter 2004 over the same period in 2003.  The
Company recorded increases in salaries and salary related expenses,
legal and audit fees, and state franchise taxes, and recorded
decreases in property taxes and other G & A expense.

Earnings per share remained flat in the first quarter 2004 at $1.47
per share, the same as reported for the first quarter 2003.

Liquidity and Capital Resources

Liquidity describes the ability of a company to generate sufficient
cash flows to meet the cash requirements of business operations.
The Company's main source of liquidity is lease rentals from
commercial tenants, borrowings on its long term revolving line of
credit used to fund property acquisitions, and income from its
investment portfolio.  Cash outflows consist of payments for
operating expenses, interest expense , income taxes, dividends to
stockholders, payments in connection with the repurchase of company
stock, payments to acquire equity securities for investment, and
repayment of borrowings on its bank credit line.  The Company's
cash flow from operations was $1,148,000 for the first quarter of
2004 compared to $1,084,000 and $1,068,000 for the first quarter of
2003 and 2002 respectively.

As of March 31, 2004, the Company's main sources of liquidity
consisted of $324,000 cash, marketable securities having a market
value of approximately $1,235,000 and $4,025,000 remaining loan
balance available on its revolving credit facility with Wells Fargo
Bank.  In addition, the Company owns unencumbered real estate
having an aggregate book value of approximately $28,100,000.
Management believes that its cash flow from operations and these
other potential sources of cash will be sufficient to finance
current and projected operations.

Contractual Obligations

The Company's only contractual obligation at March 31, 2004, was
under a revolving credit facility with Wells Fargo Bank.  At March
31, 2004, the Company had outstanding borrowings of $10,975,000
under the facility and a commitment to pay a user fee of 1/8 of 1%
(payable quarterly) on the unused portion of the $15,000,000 credit
line.  The credit facility has been extended to mature April 30,
2006.

Off-Balance Sheet Arrangements

The Company has no off-balance sheet arrangements.

Item 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES AND MARKET RISK

The Company is exposed to price fluctuations on its available for
sale marketable equity securities portfolio.  These investments are
generally in companies with large capitalizations.  The Company
does not attempt to reduce or eliminate the market exposure on
these securities.  The Company reports the results of price
fluctuations on its marketable equity securities portfolio as
unrealized holding gains and losses in its statement of income and
comprehensive income.  For the three month period ended March 31,
2004 and 2003, the Company recorded an unrealized holding loss, net
of income taxes and realized gains and losses, of $30,000 and
$49,000 respectively.

Item 4.  CONTROLS AND PROCEDURES

(a)	The President, Chief Executive Officer and the Vice President,
Secretary-Treasurer of the Company have evaluated the effectiveness
of the design and operation of the Company's disclosure controls
and procedures pursuant to Securities Exchange Act Rule 13a-15 as
of the end of the period covered by this report.   Based on that
evaluation, the Chief Executive Officer and Secretary-Treasurer
have concluded that these disclosure controls and procedures are

(b)	There were no changes in our internal control over financial
reporting during the quarter ended March 31, 2004 that have
