The document discusses Section 1031 of the US tax code, which allows for the deferral of capital gains taxes when exchanging real estate property for other "like-kind" real estate property. It notes that section 1031 can be used to increase property holdings through leverage and is underutilized, being used in less than 10% of eligible transactions. It also outlines some of the benefits of a section 1031 exchange, such as deferring capital gains taxes, increasing buying power, and exchanging into other real estate investments.
