Construction Loans in Houston, TX

What Is a Construction Loan?

A construction loan funds the build of a new home rather than the purchase of an existing one. The bank releases money in stages tied to completed milestones (foundation, framing, drywall, finish), and you pay interest only on the drawn balance during the build. At completion, either the same loan converts to your permanent mortgage (one-time close) or you close a separate permanent loan (two-time close).

Construction loans are different animals from regular mortgages. Rates are usually slightly higher, documentation is heavier (builder contract, plans, draw schedule, appraisal based on future value), and timelines are driven by the build pace. The right loan structure depends on whether you are buying a production-builder home, building custom on owned land, or tearing down and rebuilding.

Which Banks Offer Construction Loans in Houston?

Several Texas-based and national banks run active construction lending programs in the Houston metro. The list changes quarter to quarter based on each bank's appetite and rate environment, but the consistent players include:

• Frost Bank: Large Texas regional, strong for in-state construction with flexible draw schedules.
• Prosperity Bank: Houston-headquartered, competitive on one-time close for mid-to-high net worth borrowers.
• Texas Capital Bank: Private banking relationship loans, best for higher loan amounts.
• First Horizon: National lender with solid Houston construction footprint.
• BOK Financial: Strong on custom builds and physician/professional programs.
• TDECU, Amplify Credit Union, Neighborhood Credit Union: Local credit unions with some of the lowest rates for qualifying members.
• Portfolio lenders via mortgage brokers: Non-bank sources with more flexible guidelines on income docs, credit, and property type.

Each bank structures draws, inspections, contingency reserves, and rate locks differently. Rates between banks on the same file can vary by 0.5 to 1.0 percent, which on a $600K build means $35,000 to $70,000 over the life of the permanent loan. An independent broker shops the field for you without the incentive to push a particular product.

One-Time Close vs Two-Time Close Construction Loans

The biggest decision on structure is whether to close once or twice.

One-Time Close (Construction-to-Permanent)

You close one loan at the start. It covers the build period and then automatically converts to your permanent mortgage at completion. You lock your rate up front, pay closing costs once, and do not re-qualify after the build.

• Pros: One set of closing costs, one underwriting, locked rate protects you if rates rise during the build, no risk of re-qualification problems if your income or credit changes.
• Cons: Slightly higher permanent rate than a two-time close (typically 0.125 to 0.375 percent premium for the rate-lock protection).
• Best for: Most Houston buyers, especially those building in a rising-rate environment or with income that could fluctuate during the build.

Two-Time Close

A short-term construction loan during the build, then a brand-new permanent mortgage at completion. Two separate closings.

• Pros: Potentially lower permanent rate, flexibility to shop the permanent loan at completion.
• Cons: Double closing costs (typically $8K to $15K in extra fees), re-qualification required, rate risk during the build.
• Best for: Borrowers expecting rates to drop significantly during the build, or those with income situations that will look cleaner at completion.

Construction Loan Requirements in Houston

Down Payment

Most Houston construction loans require 20 to 25 percent down on the total project cost (lot plus build). Land you already own counts toward the down payment. If your lot is paid off and worth 25 percent of the project, your cash requirement can drop to near zero. VA construction loans allow 0 percent down for qualified veterans, and some FHA construction-to-perm programs allow 3.5 percent down with the right lender.

Credit Score

680 minimum for most programs, with the best rates at 720+. Portfolio programs accept scores to 640 with larger down payments. Unlike purchase loans, construction loans weigh credit heavier because the bank is underwriting a future-value asset that does not exist yet.

Income and Debt-to-Income

DTI gets calculated based on the projected permanent payment, not the construction-period interest-only payment. This trips up buyers who assume the lower interest-only number is what qualifies them. Plan around the full PITI payment from day one.

Builder and Project Documentation

The bank will require a signed builder contract, detailed plans and specs, a draw schedule, and an appraisal based on projected future value. Builder has to be approved by the bank (most banks keep an approved-builder list; an unknown builder can often get added with financial and project history documentation).

How the Draw Schedule Works

During the build, the bank releases funds in stages called draws. A typical Houston construction loan has 4 to 6 draws over 6 to 12 months, tied to milestones:

1. Draw 1: Site prep, foundation, slab (roughly 10 to 15 percent of loan)
2. Draw 2: Framing, roof, exterior sheathing (roughly 25 percent)
3. Draw 3: Mechanical rough-in (plumbing, electrical, HVAC) (roughly 15 to 20 percent)
4. Draw 4: Drywall, interior finish rough (roughly 15 to 20 percent)
5. Draw 5: Trim, cabinets, fixtures (roughly 15 percent)
6. Final draw: Punch list, final inspection, certificate of occupancy (roughly 10 to 15 percent)

Before each draw, the bank sends an inspector to verify the work is actually done. You pay interest only on the drawn balance, not the full loan amount, so your carrying cost ramps up as the build progresses.

Builder In-House Financing vs Independent Broker

Production builders (Toll, Lennar, Perry, D.R. Horton, Chesmar, Meritage, and the rest of the 17 majors in Houston) almost always have a preferred in-house lender and push you to use them with rate buydowns and closing-cost incentives tied to the financing package. Buyers see the flyer payment and think they are getting the best deal.

They are usually not. The "free" rate is priced into the home and the preferred lender's margin is wider than what an independent broker can get you. On a $500K Houston new build, we routinely show outside-lender payments that beat the preferred-lender payment by month 25 to 30, even when the preferred lender starts with a subsidized rate. The builder keeps pushing the incentive because it is worth less than what they charge for it.

Custom builds are even more lopsided. The builder has no in-house financing to offer, so the only question is which outside bank fits your file best. That is exactly what an independent broker is for. Read our full new construction buyer guide for the flyer-vs-reality payment math.

Construction Loans for VA, FHA, and Special Programs

VA Construction Loans

Qualified veterans can build with 0 percent down using a VA one-time close construction loan. Not every lender offers VA construction, so the list is shorter. Same VA funding fee and entitlement rules apply as a VA purchase loan.

FHA Construction-to-Permanent

FHA runs a 3.5 percent down construction-to-permanent program, but very few Houston lenders actively offer it because the overlays are strict and the draw inspection requirements are heavier. Available through the right broker channels.

Jumbo Construction Loans

Build budgets above the 2026 Harris County conforming limit ($806,500) require a jumbo construction loan. See our jumbo loans page for details on the permanent financing piece. Jumbo construction typically wants 25 to 30 percent down and 720+ credit.

Houston-Specific Considerations

• MUD tax rate: Many Houston build locations sit inside Municipal Utility Districts. MUD taxes can swing your monthly payment by $400 to $800. Factor this into your DTI ratio before locking in a loan amount. Use the mortgage calculator for a real picture.
• Flood zone: Anything in FEMA zones AE, A, or VE needs flood insurance. The bank will require it and the premium affects your DTI.
• Foundation and soil: Houston's expansive clay makes foundation spec critical. Banks often require a soils report before funding.
• Hurricane and wind: Coastal builds (Galveston County, parts of Brazoria) need windstorm coverage, which is a separate policy from flood and homeowners.
• Harris County appraisals: Future-value construction appraisals in Houston have tightened post-2022. Build up a contingency reserve in your budget for appraisal gaps.

The Construction Loan Process in Houston

1. Pre-qualification: We review your credit, income, assets, and project concept. This tells you the loan size you can carry. Start with our free mortgage analyzer.
2. Builder selection and contract: If you do not yet have a builder, we can point you to approved builders for your market. Builder must be acceptable to the bank.
3. Plans, specs, and budget: Finalized plans, materials specs, and itemized budget from the builder.
4. Loan application and appraisal: Full application, future-value appraisal, and bank underwriting. Typically 30 to 45 days.
5. Closing: Sign the construction loan. Lot purchase (if applicable) funds. Build begins.
6. Draws during the build: 4 to 6 inspections and fund releases over 6 to 12 months.
7. Conversion to permanent: If one-time close, the loan automatically converts at the final draw. If two-time close, you close a new permanent loan.

Frequently Asked Questions

Which banks offer construction loans in Houston?

Several Texas-based and national banks offer construction loans in the Houston metro, including Frost Bank, Prosperity Bank, Texas Capital, First Horizon, BOK Financial, and portfolio lenders working through mortgage brokers. Local credit unions like TDECU and Amplify also run active construction programs. Rates, draw schedules, and qualification standards differ significantly between banks, which is why shopping through an independent broker almost always beats walking into one bank.

What is the difference between a one-time close and two-time close construction loan?

A one-time close construction loan (also called construction-to-permanent or CTP) closes once at the start. The same loan covers the build period and then converts to your permanent mortgage automatically. You lock your rate up front, pay closing costs once, and do not re-qualify. A two-time close is two separate loans: a short-term construction loan during the build, then a new permanent mortgage at completion. Two-time close can give you a slightly lower rate on the permanent piece but requires re-qualification and second-round closing costs. For most Houston buyers, one-time close is the cleaner path.

How much do I need to put down on a Houston construction loan?

Typical Houston construction loans require 20 to 25 percent down on the total project cost (lot plus build). Some VA construction loans allow 0 percent down for qualified veterans, and some FHA construction-to-perm programs allow 3.5 percent down with the right lender. Land you already own can count toward the down payment. If the land is paid off and worth 25 percent of the project, your cash requirement can drop to near zero.

Should I use the home builder's in-house financing or an outside construction loan broker?

Builder in-house financing is structured to sell more homes, not to give you the best rate. The advertised buydown looks cheap because it is baked into the sticker price and the lender's margin is fatter than what an outside broker can access. An independent construction loan broker shops multiple Texas banks, has no incentive to lock you into a particular product, and can often match or beat the builder rate without the incentive strings. For custom builds (not production-builder spec homes), an outside broker is almost always the better call because the builder has no skin in the financing.

How does the draw schedule work on a Houston construction loan?

During the build, the bank releases funds to the builder in stages (draws) tied to completed milestones: foundation, framing, mechanical rough-in, drywall, trim, and final. Typical Houston construction loans run 6 to 12 months with 4 to 6 draws. You pay interest only on the drawn balance, not the full loan, so your monthly carrying cost is lower at the start and ramps up as the build progresses. The bank sends an inspector before each draw to verify work completed.

What credit score do I need for a construction loan in Houston?

Most Houston construction loan programs want a 680 minimum credit score, with the best rates going to 720+. Portfolio programs and some VA construction lenders go down to 640 with larger down payments. Debt-to-income has to pencil based on the projected permanent payment, not the construction-period interest-only payment, which sometimes trips people up.

Can I get a construction loan to build on land I already own in Houston?

Yes. Owned land is treated as equity and counts toward your down payment requirement. If the land is paid off and worth 20 to 25 percent of the total project cost (lot plus build), you can often do a construction-to-permanent loan with no additional cash down. If there is still a lot loan outstanding, it gets rolled into the construction loan at closing.
