Quick answer: If you're behind on your San Diego mortgage, a short sale almost always beats letting the property go to foreclosure — California law protects you from owing the difference in both cases, but a short sale keeps you in control of the timeline and does far less damage to your credit. The bigger news for 2026: the federal tax break that used to make forgiven mortgage debt tax-free just expired, and California never fully matched it in the first place. That changes the math on whether a short sale still makes sense for you, and it's worth understanding before you decide anything.
Short sale vs. foreclosure: what's actually different
A short sale is when your lender agrees to let you sell your home for less than what you owe on the mortgage, and accepts that lower amount as payment. A foreclosure is when the lender takes the property back, usually because payments stopped and nothing else got worked out first.
They can end with a similar result — you no longer own the home — but the path there is very different. A short sale is still your sale, and it works through the same process as any San Diego home sale: you (with your agent) find a buyer, negotiate the price, and control the timeline, even though your lender has to approve the final terms. A foreclosure is the lender's process, on the lender's schedule, and it shows up on your credit report and public record very differently than a sale does.
The California protection most homeowners don't know about
Here's something a lot of people facing a short sale don't realize: California law already protects you from the biggest financial fear — owing the bank money after the sale closes.
Under California Code of Civil Procedure 580e (expanded by SB 458 in 2011), once your lender agrees in writing to a short sale on a 1-to-4 unit residential property, that lender can't come after you later for the difference between what you owed and what the home sold for. This applies to first mortgages and second mortgages or HELOCs alike, as long as each lienholder consented to the short sale in writing. Lenders also can't require you to pay extra money out of pocket just to get their approval.
This is one of the clearest reasons a short sale is usually the better route than walking away and letting a foreclosure happen — you get the same debt protection, but with far more control over how it plays out.
The tax rules just changed for 2026 — read this before you decide
This is the part that's genuinely different this year, and it matters.
For years, homeowners who had mortgage debt forgiven through a short sale, foreclosure, or loan modification could exclude that forgiven amount from their taxable income under the federal Mortgage Forgiveness Debt Relief Act (the Qualified Principal Residence Indebtedness exclusion). That federal exclusion expired on January 1, 2026. It still applies if you entered into a written short sale agreement before that date, even if the sale closes later — but new agreements made from here on don't get that protection automatically.
It gets more complicated at the state level: California has been out of conformity with the federal exclusion since 2015. In practice, that has meant forgiven mortgage debt could already be taxable on your California return even in years when it was tax-free federally. Going forward, homeowners should assume forgiven debt from a short sale may be treated as taxable income on both your federal and state returns, unless you qualify for a separate exception like insolvency.
This isn't something to guess about. If you're considering a short sale, talk to a CPA or tax attorney about your specific numbers before you sign anything — the tax exposure can be a real factor in whether a short sale makes sense right now, and it's different for every homeowner's situation.
What a short sale actually looks like, start to finish
- You gather your financial picture. Lenders want to see the hardship — job loss, medical bills, a rate reset, whatever it is — along with your income, expenses, and mortgage balance.
- We price it to sell, and to get approved. The listing price has to work for a real buyer and be something your lender will sign off on, which takes local market knowledge, not guesswork — the same pricing discipline I walk through in what your San Diego home is actually worth right now.
- An offer comes in, and it goes to your lender for approval — this is usually the slowest part. Expect weeks, sometimes longer, especially if there's more than one lienholder.
- Once approved, it closes like a normal sale. You move on your timeline, not the bank's.
Is a short sale even on the table for most San Diego homeowners right now?
Probably not, and that's worth saying plainly. San Diego's foreclosure inventory has been near historic lows this year — recent county data has shown well under 50 properties in foreclosure at any given time, a small fraction of what the county saw during the 2008 downturn. Most owners who bought more than a couple of years ago have real equity, which means a straightforward sale — not a short sale — is usually the better option.
Where a short sale still comes up: recent buyers with little equity, owners who tapped a HELOC hard, or anyone facing a sudden hardship in a lower-equity part of the county. If that's you, the earlier you have this conversation, the more options stay open. A free home valuation is a good first step either way — it tells you within a few minutes whether you're actually underwater or sitting on more equity than you think.
