Should I Sell My House Before Buying My Next Home?

"Should I sell my house before buying my next one?" is the first question I hear from every move-up seller in San Antonio and the Hill Country, and the honest answer is usually yes, sell first, with one big condition: you need a plan for the time between your closing and your next one. This post reads the question from your seller's seat: what selling first does to your next offer, what happens to your equity and your calendar, and what you can demand from the buyers of your current home. The buyer-side version of this decision is covered in depth in my sell-first or buy-first guide; here the focus is on the seller's side of the Texas contract.

Selling first funds the move and strengthens your next offer

Your equity is only real when your sale closes. Sell first and that equity becomes the down payment and closing cash for your next home. Buy first and you either carry two mortgages or you write an offer that depends on your current home selling, and the seller on the other side reads that as risk: your home might not sell, might sell late, or might close after their date.

That is why a seller who is also a buyer is usually best served selling first: the offer you write after closing is non-contingent and clean, and it beats a higher contingent offer in most San Antonio multiple-offer situations. My multiple-offers comparison explains why sellers rank certainty so highly.

What a sale contingency actually looks like in Texas

The TREC One to Four Family Residential Contract (Resale), form 20-19 (effective July 1, 2026), does not put a sale-of-current-home contingency in the contract body. TREC requires the Addendum for Sale of Other Property by Buyer, TREC form 10-6, attached to the contract instead. That addendum contains the kick-out: if the seller accepts another offer, they notify you to waive your contingency within a set number of days, commonly three days, and if you do not, the contract terminates and your earnest money returns. The seller can trigger the kick-out only after signing a back-up contract with the Addendum for Back-up Contract.

In practice, sellers almost always keep that right, which is exactly why a contingent offer is weaker than a clean one. Selling first removes you from that position entirely: you become the buyer with the clean offer, not the one the seller can push out in three days.

How long "sell first" really takes in San Antonio

The second reason sellers worry about selling first is time, and the numbers show they are right to plan for it. SABOR (San Antonio Board of REALTORS) reported an average of 83 days on market in its October 2025 figures, up 17% year over year, and the San Antonio Report's March 2026 analysis of SABOR data put the average near 92 days in December 2025 and just over 100 days in early 2026. Third-party trackers put the median closer to 42 to 51 days, because a handful of slow listings pull the average up. Either way, "sell first" is a two-to-four-month plan, and that is the gap your leaseback or rental has to cover.

The leaseback that bridges the gap

The cleanest fix for sell-first is the seller leaseback: you sell, close on schedule, and rent your own house back from the new buyers while your next home closes. Texas has a dedicated form, the Seller's Temporary Residential Lease, TREC form 15-7, and it may only be used when you stay no more than 90 days after closing. Rent is set on a per-day basis and paid at funding, you put up a performance deposit, and the new owners get keys for inspections. One real limit: the buyer's mortgage lender may restrict or shorten the lease term, so confirm it against the buyer's loan.

A leaseback, a month-to-month rental, or a short stay with family each work; what does not work is closing your sale with no confirmed place to sleep. Lock the gap down before you sign the listing agreement.

The one case for buying first

Buying first wins for exactly one kind of seller: the one who cannot cover the gap. If your move date is fixed (a lease ending, a school start, a PCS report date), your lender says you qualify while carrying both payments, and no leaseback or rental is available, then buy first and accept the trade-off: two payments, plus a contingent offer that will likely lose to a cleaner one. It is the more expensive, less competitive order, which is why it is the exception rather than the rule. Rates make that trade-off visible right now: the Freddie Mac Primary Mortgage Market Survey averaged 7.03% for a 30-year fixed rate the week of September 24, 2026, up from 6.95% a week earlier. Unless the calendar forces you, do the math before committing to two payments at once. My cost to sell in Texas post and the sell-and-buy guide show both sides of the ledger.
