Jumbo Loans in Texas

Above the conforming limit, the rules change — and so does the lender you need. Here's how Texas jumbo financing really works in Dallas, Houston, Austin and San Antonio: down payment, reserves, credit, documentation, and where jumbo pricing beats conforming.

What makes a loan "jumbo" in Texas

A jumbo loan is simply a mortgage larger than the conforming loan limit published each year by the FHFA. Loans at or below that limit can be sold to Fannie Mae and Freddie Mac; loans above it cannot, so they're held by banks or sold to private investors with their own guidelines.

Nearly every Texas county uses the baseline one-unit limit — Texas has no high-cost county designations the way coastal metros do. Because the limit is updated annually, confirm the current figure for your county before you shop; a purchase that was jumbo last year may be conforming this year.

Jumbo qualifying: what actually matters

  • Down payment. 10% is a common entry point, 20% unlocks the best pricing, and files above roughly $2 million usually want 20–30%. A handful of portfolio programs will consider 5% down on exceptional files.
  • Credit score. 700 is a practical floor for most jumbo investors, 720+ is comfortable, and 760+ earns the sharpest pricing. Some portfolio lenders go to 680 with compensating factors.
  • Reserves. This is the requirement that surprises people. Expect 6–12 months of full mortgage payments in liquid or retirement assets after closing, and more on larger loan amounts or second homes.
  • Debt-to-income. Typically capped near 43%, sometimes 45–50% with significant reserves or asset depletion income.
  • Appraisal. Two appraisals were once standard above certain loan amounts; today most programs require one, with a second review on very large files or unique properties.

Are jumbo rates higher? Often not

The common assumption is that jumbo loans cost more. In practice, because jumbo pricing is set by portfolio lenders competing for high-net-worth relationships rather than by agency guarantee fees, jumbo rates frequently land at or below conforming for borrowers with strong credit, real reserves, and 20% down.

Jumbo also avoids agency loan-level price adjustments entirely, which is why a $900,000 jumbo can sometimes price better than a $780,000 conforming loan on the same file. Structure matters more than the label — see how mortgage rates actually work.

Documentation paths for jumbo borrowers

  • Full documentation. Two years of returns, W-2s, paystubs, and asset statements. Best pricing, most straightforward path.
  • Bank statement jumbo. Qualify on 12–24 months of business or personal deposits instead of tax returns — the standard solution for business owners whose write-offs suppress taxable income. See the bank statement program.
  • Asset depletion / asset qualifier. Convert liquid assets into a qualifying income stream. Common for retirees and equity-rich relocation buyers.
  • Non-QM jumbo. For complex structures — recent credit events, foreign income, trust or entity ownership. Details on the Non-QM page.

Where Texas jumbo lending happens

Dallas–Fort Worth

Highland Park, University Park, Southlake, Westlake, Preston Hollow and Frisco's custom-build corridors generate most DFW jumbo volume. New-construction jumbo files here often need extended rate locks and careful appraisal timing.

Dallas–Fort Worth mortgage lending

Houston

River Oaks, Memorial, West University, The Woodlands and Bellaire dominate Houston jumbo lending. Flood zone determination and insurance cost materially affect qualifying DTI, so we price insurance early on any file near a bayou or reservoir.

Houston mortgage lending

Austin

Westlake Hills, Tarrytown, Barton Creek and Lake Travis routinely trade well above conforming limits. Equity-rich buyers relocating from higher-cost states often pair a jumbo with an asset-based qualification structure.

Austin mortgage lending

San Antonio

Alamo Heights, Terrell Hills, Olmos Park and Stone Oak's upper tier make up the local jumbo market, where appraisal comparables can be thin and a lender relationship matters.

San Antonio mortgage lending

Jumbo vs. two loans

A common alternative is a conforming first mortgage plus a second lien or HELOC to stay under the limit. It can work, but it's rarely cheaper today: the blended rate on a piggyback structure usually exceeds a single well-priced jumbo, and you carry two payments and two sets of terms. The exception is a borrower who needs a small amount over the limit and expects to pay the second down quickly.

Run both structures side by side in the mortgage calculator before you decide.

Frequently asked

Does a jumbo loan require mortgage insurance?

Most jumbo programs don't offer traditional PMI at all — instead they require a larger down payment. A few investors allow 10% down with a pricing adjustment rather than monthly insurance.

Can I buy an investment property with a jumbo loan?

Yes, with more down payment and reserves. For rental portfolios, a DSCR loan is frequently the better structure because it qualifies on property cash flow.

How long does a jumbo loan take to close?

Typically 30–45 days. Jumbo underwriting is manual rather than automated, so complete documentation up front is the single biggest factor in speed.

Can I refinance a jumbo loan later?

Yes, including cash-out — though on a Texas homestead the state's 80% equity ceiling applies. See the Texas cash-out refinance guide.
