Houston: Buying Before Your Current Home Sells
Program and regulatory figures verified September 17, 2026. Details change; confirm your scenario with us.
Whether you are moving from Katy to The Woodlands or from the Heights to Bellaire, the financing question is the same: can you buy before you sell, and how.
The Houston move-up picture
Houston runs on a lot of internal movement. Families leave Cypress and Katy for Memorial and Bellaire, or head north into The Woodlands and Spring for schools and space, or move in toward the Heights and Montrose for the commute. Almost all of it involves selling one Houston-area house and buying another, which is exactly the transaction this site exists for.
The constraint is statewide and it does not soften inside the Beltway. Everything secured by your homestead has to fit under 80 percent of fair market value, counting the mortgage you already carry, and a subordinate HELOC cannot sit behind a Texas Section 50(a)(6) loan.
Property taxes are the local variable
Houston spans several counties and a great many taxing entities, and the rate you inherit depends on exactly where the new house sits. Harris, Fort Bend, Montgomery and Brazoria counties do not tax alike, and a municipal utility district can add meaningfully on top in the newer master-planned areas.
This matters for qualifying, not just for your budget. Property taxes are inside the housing payment underwriting measures. Moving from an older inner-loop property to a newer MUD-served subdivision can raise the tax line more than the price difference alone suggests. Get the actual figure for the actual address before you plan around an estimate.
Which structure Houston owners tend to use
Where equity is strong and the departing home will move quickly, carrying both and recasting afterwards is the cleanest path. Where the old house sits in a solid rental submarket, and much of Houston does, renting it instead converts the timing problem into an income question and sidesteps the homestead ceiling entirely.

Frequently asked questions
Can I buy in The Woodlands before selling my Houston home?
Yes, and there are three ways to structure it: carry both payments and recast once the sale closes, use bridge financing if your equity supports it under the Texas 80 percent homestead ceiling, or rent the departing house and qualify on that income. Which one fits depends on your numbers rather than on where in the metro you are moving.
Do Houston property taxes affect what I can qualify for?
Yes. Property taxes are part of the payment underwriting measures, and rates vary across Harris, Fort Bend, Montgomery and Brazoria counties, with municipal utility districts adding more in some newer subdivisions. The actual figure for the actual address is worth having before you plan.
Is the loan limit different in Houston?
No. The 2026 baseline conforming limit of $832,750 applies, and no Houston-area county is designated high-cost, so there is no metro-specific figure.
