How We Saved a Sale-to-Purchase Deal in San Diego When the Buyer's Financing Fell Through

My client was selling his Otay Mesa condo to buy a smaller one in Mission Valley, closer to family and back in the walkable, dog-friendly lifestyle he missed. A week before closing, the buyer on his sale lost financing — putting his own purchase at risk. We found a new lender, got him preapproved in 48 hours, and closed both transactions.

Why was he moving from Otay Mesa to Mission Valley?

He was moving for lifestyle and family. After two years building equity in his 2-bed, 2.5-bath condo in the Otay Mesa community, he wanted to be closer to family and back in central San Diego — his preferred part of the city. He'd lived near Mission Valley before, and he missed being able to walk his dog, Hercules, grab dinner nearby, and stop by the farmers market. The move traded for a condo in the location he wanted back.

What was his biggest concern going in?

His biggest concern was financing — specifically, qualifying for the new home and keeping his monthly payment where it was and his low interest rate. He needed the sale of his Otay Mesa condo to fund the 20% down payment on the Mission Valley purchase, so the two transactions were tied together from the start. If the sale didn't close, the purchase didn't happen.

How did we structure the sale and purchase together?

We accepted a non-contingent offer on his Otay Mesa condo and negotiated a 7-day seller-in-possession period so he could stay put until movers were lined up and move the following weekend. Both transactions were coordinated to close simultaneously, so he wouldn't be without a home in between.

What went wrong right before closing?

The buyer purchasing his Otay Mesa condo lost financing. The original lender's underwriting couldn't make the loan work for that buyer, and the denial was final — there was no path forward with them. Because my client needed that sale to close in order to fund his own down payment, and we were already in escrow on his replacement property in Mission Valley, his purchase was suddenly at risk too.

Why didn't we just extend the timeline with the original lender?

We considered it, but the original lender's decision was final — there was no version of that loan that was going to work. Speed mattered more than patience at that point, because every day put my client's own purchase further at risk. So instead of waiting on a lender who had already said no, I moved to replace them.

What did you do to save the deal?

The same day the loan fell through, I reached out to a qualified in-house lender at my brokerage. We got the buyer preapproved within 48 hours, which kept the sale alive and protected my client's purchase. The buyer still had some hurdles to clear in finalizing that loan, which meant extending the closing dates — but the deal held together.

What was the final result?

Both transactions closed, back-to-back — the sale first, then the purchase the next day. And because the price on his Mission Valley home came in lower, combined with his down payment, my client now owes less on his mortgage than before and is saving a few hundred dollars a month — even after moving to the more central location he wanted.

What would you tell someone in the same situation?

Have a plan, but also make sure you have the right team around you. When you're selling your current home in order to buy your next one, there are a lot of moving pieces, and sometimes things happen that are completely outside your control. In this case, the buyer's original financing became an issue, and that could have affected not only the sale, but my client's replacement purchase too. That's where having an experienced team really matters. We didn't panic — we looked for solutions, brought in another lender who could perform, protected the replacement purchase, and coordinated the timelines so my client could transition from one home to the next.

FAQ

What happens if the buyer of my home loses their financing right before closing? It doesn't automatically mean your sale — or a purchase you're depending on it for — is dead. If the original lender's denial is final, the fastest path is usually replacing the lender rather than waiting. An agent with lender relationships can move quickly to requalify the buyer and keep the timeline as close to intact as possible.

Can I sell one home and buy another at the same time without a financing gap? Yes, but it takes coordination. In this case, we used a non-contingent offer on the sale, a short seller-in-possession period, and aligned closing dates so the seller could move directly into his next home without a gap.

Is it risky to depend on your sale proceeds for your next down payment? It carries real risk if something goes wrong with the buyer's financing, since the two transactions become linked. That risk doesn't mean you shouldn't do it — it means you need contingency options and a team that can act fast if something changes.

Does moving to a smaller home mean a bigger mortgage payment? Not necessarily. In this case, the client moved from a larger unit to a smaller one in a more central location, and still ended up with a lower mortgage balance and monthly payment, because of how the numbers on the second property, negotiated credits to buy down his rate and his down payment worked out.
