Real Property Investments

The discussion under this section, which starts on page 98 of our prospectus, is modified and supplemented by the following information regarding properties we have acquired or intend to acquire.

Huebner Oaks Center, San Antonio, Texas

On June 8, 2004, we purchased an existing shopping center known as Huebner Oaks Center, containing 286,738 gross leasable square feet. The center is located at I-10 and Huebner Road, in San Antonio, Texas.

We purchased this property from an unaffiliated third party. Our total acquisition cost was approximately $79,721,000. This amount may increase by additional costs which have not yet been finally determined. We expect any additional costs to be insignificant. Our acquisition cost was approximately $278 per square foot of leasable space.

We purchased this property with our own funds. However, we expect to place financing on the property at a later date.

We do not intend to make significant repairs and improvements to this property over the next few years. However, if we were to make any repairs or improvements, the tenants would be obligated to pay a substantial portion of any monies spent pursuant to the provisions of their respective leases.

One tenant, Bed, Bath & Beyond, leases more than 10% of the total gross leasable area of the property. The lease with this tenant requires the tenant to pay base annual rent on a monthly basis as follows:

			Base Rent
	Approximate		Per Square
	GLA Leased	% of Total	Foot Per	Lease	Term
Lessee	(Sq. Ft.)	GLA	Annum ($)	Beginning	To

Bed, Bath & Beyond	35,009	12	10.62	03/97	01/08

For federal income tax purposes, the depreciable basis in this property will be approximately $60,006,000. When we calculate depreciation expense for tax purposes, we will use the straight-line method. We depreciate buildings and improvements based upon estimated useful lives of 40 and 20 years, respectively.

Huebner Oaks Center was built between 1997 and 1998. As of June 1, 2004, this property was 97% occupied, with a total 278,515 square feet leased to fifty-five tenants. The following table sets forth certain information with respect to those leases:

Pine Ridge Plaza, Lawrence, Kansas

On June 7, 2004, we purchased an existing shopping center known as Pine Ridge Plaza, containing 226,471 gross leasable square feet. The center is located at 3106 - 3140 Iowa Street, in Lawrence, Kansas.

This amount may increase by additional costs which have not yet been finally determined. We expect any additional costs to be insignificant.
