A rental foreclosure is treated as a property disposition for federal tax purposes. With recourse debt, a separate cancellation-of-debt question may also arise; with nonrecourse debt, the unpaid debt is generally part of amount realized.

First determine who remained liable for the debt

Recourse debt means the borrower is personally liable for the unpaid balance under the applicable documents and law. Nonrecourse debt generally limits the lender to the collateral. A loan's label is a starting point, not the complete answer: guarantees, modifications, state law, and deficiency rights matter. Obtain the note, guarantees, foreclosure notice, payoff calculation, and any deficiency waiver before preparing the return.

The property disposition is measured against adjusted basis, which includes appropriate capitalized costs and reflects depreciation allowed or allowable. A foreclosure can create gain even when the owner receives no cash. Suspended passive losses, at-risk rules, and prior depreciation may change the tax return consequences, so do not equate “I lost the property” with a tax loss.

Two different calculations

For nonrecourse debt, the full unpaid debt generally enters amount realized when the lender takes the property, even if it exceeds fair market value. There usually is no separate cancellation-of-debt income from that same discharge. For recourse debt, amount realized generally reflects the property's fair market value; the difference between the debt and that value can be cancellation-of-debt income if the lender forgives it. The COD amount may qualify for an exclusion, but exclusions have their own requirements and possible tax-attribute reductions.

Illustrative comparison

Assume adjusted rental basis is $400,000, unpaid debt is $500,000, and fair market value at foreclosure is $350,000. In a simplified nonrecourse case, the $500,000 debt can be the amount realized, producing $100,000 disposition gain. In a simplified recourse case, the $350,000 property value can produce a $50,000 disposition loss, while the remaining $150,000 of forgiven debt is analyzed separately as COD income. Transaction costs, other liabilities, debt terms, and loss limits can change an actual return.

Do not overlook the tax forms

A lender may issue Form 1099-A for acquisition or abandonment of secured property and Form 1099-C for cancelled debt. These are evidence to reconcile, not a substitute for the legal and basis analysis. Confirm the property's fair market value, outstanding principal, accrued interest treatment, and dates on the forms. If an insolvency or qualified real property business indebtedness exclusion may apply, evaluate the precise tests and Form 982 rather than omitting the income by assumption.

The rental tax hub links to basis and loss guides. IRS Publication 4681 explains foreclosures and debt cancellation, and Publication 544 covers property dispositions.

Separate economic loss from tax character

A property purchased for $600,000 may have an adjusted basis far below that amount after years of depreciation. This can produce tax gain at foreclosure despite a steep fall in market value. A recourse case can also have a property loss and ordinary cancellation-of-debt income in the same year; those amounts are not automatically netted into one capital loss. A reviewer should determine disposition character, passive-loss effects, and COD exclusions in the correct order.

Timing also matters. The foreclosure or deed-transfer date may differ from the date the lender later cancels a deficiency balance. If the owner negotiates a short sale or deed in lieu, read the settlement and release documents to see which obligations ended and when. Retain evidence of fair market value at transfer, such as an appraisal or broker analysis, because a lender form can use an amount that needs investigation.

The debt's tax basis can also differ from the statement balance if it includes unpaid interest or fees. Interest that would have been deductible if paid may receive separate treatment when forgiven. Ask for a transaction-level lender ledger rather than using only the headline 1099-C amount. This matters most when the lender capitalized fees or the borrower made payments after default.
