Debt Replacement

Debt replacement is the requirement, in a fully tax-deferred 1031 exchange, that the investor offset any mortgage debt retired on the relinquished property by taking on at least as much new debt on the replacement property or by contributing equivalent additional cash. The principle behind it is that full deferral requires the investor to acquire replacement property of equal or greater value and to reinvest all equity; a drop in debt without an offsetting cash contribution leaves a slice of value, called mortgage boot, that becomes taxable. An investor who sells a property with a $500,000 mortgage and buys a replacement of equal price but finances only $300,000 must add $200,000 of cash to avoid recognizing $200,000 of boot. Debt replacement is one reason fractional vehicles such as Delaware Statutory Trusts are popular for exchanges: many DST offerings carry pre-arranged, non-recourse property-level financing, so an investor's pro-rata share of that debt can satisfy the replacement requirement without the investor personally qualifying for or signing a new loan. Getting debt replacement right is a core part of structuring an exchange and should be confirmed with a tax advisor before the relinquished sale closes.
