NATIONAL PROPERTIES CORPORATION
NOTES TO THE FINANCIAL STATEMENTS

The balance sheet at June 30, 2004, and the statements of income and
comprehensive income and cash flows for the periods ended June 30, 2004,
and June 30, 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 June 30, 2004, $10,450,000 ($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 June 30, 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 June 30, 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 June 30, 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.

Board of Directors Approve Dividend Payment

At the Company's annual meeting of Stockholders held May 21, 2004, the
Company declared a $0.18 per share dividend to be paid July 30, 2004 to
stockholders of record on June 30, 2004.  The dividend totals $73,644.

Operating Results

Lease revenues increased 5.7% or $161,000 in the first half of 2004 over
the same period in 2003.  The increase in lease revenues relative to the
first six months of 2003, was attributable to: (1) the acquisition of a
restaurant property in August 2003 and a drug store property in November
2003, which in the aggregate added $282,000 to lease revenues in the first
six months of 2004, (2) a decrease in lease revenues of $118,000 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
$16,000 due to escalation clauses in the lease agreements of some tenants
and renegotiated leases with other tenants.

The Company recorded investment income, including gains from the sale of
marketable securities, of $38,000 in the first six months of 2004 compared
to $34,000 for the first half of 2003.

The Company recorded no property sales in 2004 compared to recording a gain
of $40,000 from the sale of an easement to Company owned property in
Arlington, Texas in 2003.

Operating expenses increased $82,000 or 7.9% in the first six months of
2004 over the same period in 2003, as a result of increases in
depreciation, professional fees, and compensation costs.

Depreciation expense increased a net $57,000 in the first half of 2004 over
the same period in 2003.  Depreciation increased approximately $84,000 from
new property acquisitions in 2004 and 2003, and decreased approximately
$27,000 from the disposition of the Company's two garden centers in 2003.

Interest expense decreased slightly in the first half 2004 from the same
period in 2003 due to a lower borrowing cost on the Company's line of
credit.  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.
Average outstanding debt in the first six months of 2004 was $11,129,000
compared to $10,282,000 for the same period in 2003.  The average interest
rate on borrowings during the first six months of 2004 was 3.30% compared
to 3.62% in the first six months of 2003.

Other general and administrative (G & A) expenses increased a net $28,000
in the first half of 2004 over the same period in 2003.  The Company
recorded increases in salaries and benefits, legal and audit fees, and
state franchise taxes, and recorded decreases in property taxes, insurance
and travel expenses.

Earnings per share increased $0.07 to $2.91 per share in the first half of
2004 over the $2.84 per share earned in the first half of 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 $1,711,000 for the first six months of 2004 compared to
$1,657,000 and $1,559,000 for the first six months of 2003 and 2002,
respectively.

As of June 30, 2004, the Company's main sources of liquidity consisted of
$356,000 cash, marketable securities having a market value of approximately
$1,253,000 and $4,550,000 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
$27,800,000.  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 June 30, 2004, was under a
revolving credit facility with Wells Fargo Bank.  At June 30, 2004, the
Company had outstanding borrowings of $10,450,000 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 six month period
ended June 30, 2004, the Company recorded an unrealized holding loss, net
of income taxes of $13,000 compared to a net unrealized gain of $80,357 for
the first six months of 2003.

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 President, Chief Executive Officer and Vice President,
Secretary-Treasurer have concluded that these disclosure controls and
procedures are effective.

          (b)  There were no changes in our internal control over financial
reporting during the quarter ended June 30, 2004 that have materially
affected, or are reasonably likely to materially affect, our internal
controls over financial reporting.

PART II.   OTHER INFORMATION.

                No applicable items.

Item 6.    EXHIBITS AND REPORTS ON FORM 8-K.

immediately precedes the exhibits and which is incorporated by reference
herein.
