Methods and investment instruments for investing in real estate are described wherein a portfolio of investment real estate is divided into a plurality of tenant-in-common deeds of predetermined denominations, and which are subject to a master agreement and master lease to form “deedshares.” Holders of the deedshares receive a guaranteed income stream from the master lease and yearly depreciation, without having to maintain or manage the real estate. The holders of deedshares are subject, under the master agreement, to a mechanism that enables the master tenant to purchase, or arrange for the purchase of the deedshares at fair market value (or some other calculable value) at the end of a specified term. Because the deedshares qualify as interests in investment real estate, they are eligible for tax-deferred treatment under §1031 of the Internal Revenue Code.
