4. Taxpayers must use all the proceeds from the sale of their relinquished property to purchase replacement property.
In order to have a completely tax-deferred exchange a taxpayer must follow three essential steps: (1) buy replacement property where the value is equal to or greater than the value of the original relinquished property; (2) use all of the original equity realized from the sale to purchase a replacement property; and (3) obtain equal or greater financing on the replacement property as was paid off on the relinquished property at the time of its sale.
However, while those are the rules for a complete deferral, a taxpayer may violate any one of them and complete a partial deferred exchange. For example, a taxpayer who seeks to buy a replacement property of a lesser value, or with less financing, will recognize a capital gains tax on that amount not reinvested in the new property. Simply put, taxpayers can buy replacement properties for a lesser amount and put cash in their pocket, so long as they don't mind paying some taxes.
