Houses Are Selling in 37 Days and Condos in 44 — Which Direction You're Moving Changes Everything

Overview

Most advice about selling and buying at once is generic. This one isn't, because San Diego's market is currently lopsided in a way that changes the answer depending on which direction you're moving.

Here are the September 2026 numbers from the Greater San Diego Association of Realtors:

| | Detached houses | Condos & townhomes |

|---|---|---|

| Median price | $1,079,000 (+5.8% YoY) | $670,000 (−0.2% YoY) |

| Days on market | 37 (down 9.8%) | 44 (up 4.8%) |

| Months of supply | 2.4 (down 14.3%) | 4.0 (up 5.3%) |

Read that again, because it's the whole article.

Houses are getting scarcer and selling faster. Condos are getting more plentiful and selling slower.

So your position depends entirely on which way you're going:

• Selling a house, buying a condo — you're in the easy direction. Your sale is the strong side of the trade and your purchase is the weak side. You have leverage on both ends
• Selling a condo, buying a house — you're in the hard direction. Your sale takes longer in a softening segment while you compete for something with 2.4 months of supply. This is the sequencing problem that needs real planning

Most people in San Diego trading up are in the second category. That's who the rest of this is for.

What the Market Actually Looks Like

County-wide, from the California Association of Realtors' September report, released October 19, 2026:

• San Diego County median price: $1,050,000 — down 3.7% from August, up 6.1% from a year earlier
• Sales down 12.2% year over year

Statewide, for context: median days on market 29, down from 32 a year ago, and the sales-price-to-list-price ratio is 98.8%, up from 98.2%.

That 98.8% figure is the one to hold onto. Homes in California are closing at just under asking, on average — not dramatically over, not dramatically under. It's a market where a well-priced home sells and an optimistically-priced one sits.

Note: C.A.R.'s $1,050,000 and SDAR's $1,079,000 aren't contradictory — C.A.R. tracks existing single-family detached county-wide, SDAR reports MLS detached and attached separately.

Sales volume being down 14% matters to you as a seller in a specific way: fewer transactions means fewer competing listings, but also fewer active buyers. Your house will likely sell; it may not sell on your timeline. That's the risk sequencing has to absorb.

The Contingent Offer

The standard California tool is a C.A.R. form called the COP — "Contingency for Sale of Buyer's Property." It's worth understanding its mechanics, because the defaults are specific and most people negotiating one don't know what they're agreeing to.

If your home isn't in escrow yet: you get a set number of days — the form's default is 17 — to get it into escrow and deliver "Escrow Evidence" to your seller.

If your home is already in escrow: you deliver that evidence within a shorter window, default 5 days after acceptance.

Then the part that surprises people:

The seller can keep marketing, and if they accept a back-up offer they can force your hand.

Under the form, once a seller accepts a back-up offer and gives you a copy, they may serve a "Notice to Remove Contingencies." You then have a set number of days — default 3 — to remove your sale contingency, remove your loan contingency, and demonstrate you have funds to close without selling your home. If you can't, the seller may cancel.

There is a clause that protects you from exactly this, and it's the single most important thing to negotiate:

The form contains an option that bars the seller from serving that notice during the first 17 days after acceptance — and optionally for the entire contingency period.

If you're writing a contingent offer, that provision is what turns it from precarious into workable. Ask for it by name.

One correction worth making, because you'll hear it: there is no "72-hour clause" in the California form. That's an out-of-state convention. California's deadlines are expressed in days, and they're negotiable.

On how often contingent offers actually get accepted here: no one publishes that data for San Diego. Not C.A.R., not SDAR, not the national portals. Anyone quoting you a percentage is making it up. What we can say from the real numbers is that detached homes at 2.4 months of supply are the hardest place to win with a contingency, and condos at 4.0 months are the easiest.

The Rent-Back — and the 30-Day Line

If you sell first and need time before your purchase closes, California's standard tool is the SIP — the "Seller License to Remain in Possession Addendum."

The critical thing about it: it grants a licence, not a lease, and it's built for stays of under 30 days.

At 30 days or more, the form itself directs the parties to a different document — the Residential Lease After Sale — and at that point you are a tenant, with tenant protections and potentially local rent control implications attaching.

That 30-day line is the single most useful fact in this section. A 25-day rent-back and a 35-day rent-back are legally different animals.

How the short version works:

• You pay a non-refundable per-day licence fee, either deposited with escrow before closing or withheld from your proceeds
• It isn't refunded if you leave early, absent a written agreement
• There's no security deposit as such — instead a separate Delivery of Possession fee, returned to you if you hand over the property in the required condition on the required date
• You pay the utilities
• The buyer may enter on 24 hours' notice, or at any time in an emergency
• The buyer does not insure your belongings, including vehicles. Carry your own cover
• The form states you have no right to remain beyond the term and may be liable for court-awarded damages if you hold over

Negotiate the daily rate and the delivery fee as carefully as you'd negotiate price. On a $1 million home, a rent-back of a few weeks is a meaningful number.

Bridge Financing: What's Actually Verifiable

We're going to be unusually careful here, because this is the part of the subject where you'll find the most confident writing and the least real information.

There is no neutral, published source on bridge loan availability or pricing in San Diego. What's publicly documented comes from lenders' own marketing pages, and we'll label it as such.

One California lender publishes a structure that gives you the shape of the thing: an investor lends up to 75% combined loan-to-value against your departing home without paying off your existing first mortgage; no upfront fees and no payments on the cash-out portion; you pay 2.4% of the departing home's sale price when it sells, and you must contract to buy the new home within 90 days.

The same lender offers a different product where no money changes hands at all — a flat fee for an investor guarantee to buy your departing home if it doesn't sell, $2,500 for homes up to $1.3 million and $3,500 above that, giving you 120 days to sell it yourself. That's effectively insurance against being stuck, and for a lot of people it's a better fit than borrowing.

Two important caveats. No interest rates are disclosed for any of these — so treat the fee figures as the only hard numbers. And a second bridge product from the same lender, the one that does pay off your existing first mortgage, is described as available only in the Bay Area. Don't assume a product you read about elsewhere in California is offered here.

On using a HELOC before you sell: the verifiable mechanics are simple — it's secured by your departing home and must be paid off from the sale proceeds at closing. Beyond that, we found no authoritative source on current lender appetite, draw limits, or whether lenders restrict HELOCs on homes about to be listed. Those are real questions and they need a named local lender's answer, not a blog's.

Proposition 19: the 55-Plus Advantage

If you're over 55, this is the most valuable thing on this page, and it's widely misunderstood.

You can transfer your property tax base to a new home up to three times, anywhere in California.

That's the headline. The details that matter:

• Three transfers, and the Board of Equalization confirms you get three even if you previously used a transfer under the old Propositions 60, 90 or 110
• Any county to any county. This is the big change from the old rules, which depended on whether the destination county participated
• A two-year window. The replacement home must be bought or newly built within two years of selling the original
• You can buy first. The order doesn't matter, as long as the original sells within two years of the purchase

That last point is the one that changes how you can sequence a move, so here's the catch attached to it: if you buy first, you pay property tax on the replacement home's full market value until the original sale closes — and there's no refund for that period. So buying first is permitted, but it costs you.

How the value carries over:

• If the replacement is worth the same or less than the original's market value, your taxable value transfers unchanged. The BOE's own example: a $300,000 taxable value carries to a $700,000 replacement where the original's market value was $900,000
• If the replacement is worth more, the excess is added. New taxable value equals your old taxable value plus the difference between the two market values. The BOE example: $300,000 + ($700,000 − $600,000) = $400,000
• There's grace at the margin: a replacement up to 105% of the original's value in the first year, or 110% in the second, carries over with no excess added

And the filing detail that costs people real money:

You file form BOE-19-B with the assessor in the county where the replacement home is, within three years. It is not filed through escrow — you file it after both transactions close and you're living in the new home.

If you file late, the claim can still qualify, but relief begins the year you file. There's no retroactivity. Which means a forgotten form is a permanently higher tax bill for the years you missed.

One thing to be clear about: the inflation-adjusted $1,044,586 figure you may have seen belongs to the parent-child transfer exclusion, not this one. They're different provisions and they get conflated constantly.

How to Sequence It

In rough order of how much risk you're carrying:

1. Sell first, rent-back under 30 days. Lowest risk, least flexibility. You know your number before you commit
2. Sell first, rent short-term. Costs you a move and storage, but you buy as a non-contingent buyer, which in a 2.4-month detached market is a genuine advantage
3. Buy with a contingency, with the 17-day protective clause. Workable, and much more workable on a condo than a house
4. Bridge or guarantee product. Costs a fee, buys you a non-contingent offer
5. Buy first on your own balance sheet. Most flexibility, most exposure — and if you're over 55, the Prop 19 clock starts the day you buy

There's no universally right answer. There's an answer that fits your equity, your income, your tolerance for moving twice, and which direction you're trading.

Things Worth Knowing

• Check which direction you're moving first. House-to-condo is the easy trade right now; condo-to-house is the hard one.
• Ask for the 17-day protective clause by name on any contingent offer.
• There's no 72-hour clause in California. Deadlines are in days and they're negotiable.
• Thirty days is the rent-back line. Under it you're a licensee; at or over it you're a tenant.
• Prop 19 gives you three transfers, any county, and you may buy first — but you pay full market-value tax until the original sells.
• File BOE-19-B yourself. Escrow doesn't do it, and late filing isn't retroactive.
• Nobody publishes contingent-offer acceptance rates for San Diego. Be suspicious of anyone who quotes one.
• Ask a lender about bridge options rather than reading about them. Rates aren't published anywhere.

The Bottom Line

Selling and buying at once in San Diego is a sequencing problem, not a financing problem, and the sequencing depends on the segment you're leaving and the one you're entering.

Right now that's unusually knowable: 2.4 months of detached supply against 4.0 for attached, 37 days against 44. If you're selling a house, you're on the strong side. If you're buying one, you're on the weak side. Most people moving up are both at once, which is exactly why it needs planning rather than optimism.

And if you're over 55, work out your Prop 19 position before you do anything else. Three transfers, any county, and the ability to buy before you sell is a large amount of flexibility — and the form you have to remember to file yourself is the cheapest money you'll ever save.
