Sounds wrong the first time you hear it. Sold for less than you paid, or handed the keys back, real money gone, and still a tax bill. But it happens, and in this market it is about to happen a lot. Bank multifamily delinquencies are running several times their 2022 low and sit at their highest level since the financial crisis. More of these loans are ending at the lender, and every one of those exits runs the math below.

The short version of why: every year you owned it, depreciation wrote the place down and lowered your basis. Sell, and the gain is measured against that floored basis, not against what you paid. So a price below your cost can still throw a gain. That is recapture, and it does not care that you lost equity. And if the loan is recourse, the forgiven balance can land on you as cancellation-of-debt income, even though no cash ever shows up. If it is nonrecourse, it works the other way: the whole balance folds into your sale proceeds and pushes the gain higher instead. Either way the exit bites, but which one you are in changes most of the moves below.

That part has been said. The part nobody finishes is what actually changes the size of that bill. Here is the field guide.

Suspended losses free up when you fully exit. As a passive investor, most of the paper losses you got each year you probably could never use, they just piled up suspended. Sell your whole interest in a fully taxable sale to an unrelated buyer and they release, and they can finally offset the gain, including the ordinary recapture piece. That alone can be the difference between a bill and no bill. But it takes a full sale of your interest, not a partial one. And if you already burned those losses against other passive income, that cushion is gone, and here it gets nasty: the code pulls your share of the fast depreciation back out as ordinary income first, while the loss on the rest of your stake is a capital loss that can only cover $3,000 of it a year. Ordinary tax due now, the loss that should cover it stranded, trickling out a few thousand at a time.

Seller financing does not spread the whole thing. A lot of these are trading on seller carry right now, and people assume spreading the payments spreads the tax. It spreads the gain, not the recapture. The recapture is due in full the year of the sale, cash or not. Set it up expecting to pay slowly and you can still owe a chunk up front, on money you have not collected yet.

Insolvency can erase the debt piece. If your liabilities top your assets at the moment the debt gets forgiven, that phantom income can be excluded. Fact-specific and it has to be documented at the time, but it is the main relief on a handback. The catch is you pay for it by reducing tax attributes, your basis and carryovers, so it is relief now bought with a little pain later.

There is a second lever on the debt piece most people never reach for. If it is qualifying real property business debt, a non-corporate owner can elect to exclude the forgiven amount by writing down basis in the property instead. You trade tax now for less depreciation or more gain later, but on a handback where insolvency does not fully cover you, it is the other card in the deck.

A 1031 only covers part. It defers the real-property gain, but the slice of your cost-seg study that is true personal property, Section 1245 property, stopped qualifying for the exchange at all after 2017. That piece gets stranded, recapture due, even inside a 1031. The 15-year land-improvement portion is still real property and rides along, so it is only the personal-property slice that bites, but on a heavy cost-seg that slice is not small.

Holding wipes it. Die owning the property and the basis steps up, the whole recapture gone for your heirs. Not a plan for a distressed seller, but it is why "never sell" is a real strategy for anyone who can wait.

None of these work if you find out after the closing. The pre-tax return everyone underwrote never showed any of this, because it only lands at the exit, and a forced sale with no cash back and a tax bill anyway is exactly the case a pro forma skips. This is a run-the-number-before-you-sign thing.

I am a CPA and former Big 4 CRE auditor, and this after-tax gap is the piece I work. Not pitching anything, just flagging what I keep watching people miss.

For the group: anyone had an exit where the tax came in worse than the deal itself ever justified?
