By the Numbers (illustrative example)
Most owners think of a sale as a single event: close, wire, done. If you own your industrial building free and clear, there's a second option worth understanding before you list — carrying part of the price yourself. Done right, a seller carryback note can widen your buyer pool, support a higher price, and spread your tax bill out instead of taking it all in one year. Done without the right structure, it turns you into an unsecured lender on a building you no longer control. Here's how it actually works.
What a seller carryback note actually is
In a carryback (also called seller financing), you sell the property and take back a promissory note for part of the purchase price instead of collecting all cash at close — typically the piece a bank won't cover, secured by a deed of trust against the property just like a bank loan would be. The buyer puts down cash, a bank or the seller (or both) fund the rest, and you collect principal and interest over the note's term instead of receiving that portion up front.
Why an unlevered owner would ever want to do this
If you own the building outright, your alternative to a note isn't a mortgage payoff — it's cash sitting in a money market account or bond fund. A note secured by a property you know, priced above what that cash would otherwise earn and typically below what the buyer's bank would charge, can be an attractive middle ground. It also solves a real problem for buyers: when bank underwriting is tight — low leverage, higher rates, strict debt service coverage — a carryback piece can be the difference between a deal that clears and one that doesn't. That's leverage you can use in price negotiations, not just a favor to the buyer.
The tax lever: installment sale treatment
Structured as an installment sale under IRC Section 453, a carryback note lets you recognize gain as principal payments come in, rather than all at once in the year of sale. For an owner who has depreciated a building for decades and is staring down a large gain — including the Section 1250 depreciation recapture hit most sellers underestimate — spreading recognition over the note's term can keep you out of a higher tax bracket in any single year. It is not a substitute for a 1031 exchange if full deferral is the goal, and the two don't combine cleanly on the carryback portion — get your CPA involved before you set the structure, not after.
What it does to your price and your buyer pool
A well-structured carryback is a pricing tool, not just a financing convenience. Because it removes a financing contingency and widens the buyer pool to include buyers who can't otherwise clear bank underwriting, sellers who offer it often hold firmer on price and close faster than a straight all-cash listing in the same submarket. It's most effective on properties where conventional financing is the sticking point — smaller balance sheets, thinner debt service coverage, or a building type a bank is cautious on.
Pro Tip: The note is only as good as its security and its exit
Underwrite the buyer the way a bank would — down payment size, liquidity, operating history — before you agree to hold paper. Record a deed of trust, require an assumable due-on-sale clause, insurance naming you as an additional loss payee, and a personal guarantee where possible. And build in your own exit: most carryback notes include a right to sell the note itself at a discount if you need liquidity before it matures.
The risk side, plainly
You're taking on the buyer's credit risk on a portion of the price, and if they default, your remedy is a foreclosure process, not a phone call — that means legal cost, time, and the possibility of taking the building back in a worse market than the one you sold into. This is exactly the kind of note structure and security-instrument work that warrants a real estate attorney's review before you sign anything, and it's general information here, not legal or lending advice.
