How Construction Loans Work in Texas
Building a custom home usually involves two different jobs: financing the construction itself and financing the finished home for the long term. We can help with either a one-time-close construction loan or, in many cases, a simpler two-step strategy using a local bank for construction and Guarantee Mortgage for the permanent mortgage after the home is complete.
What is a construction loan?
A construction loan is short-term financing used to pay eligible building costs while a new home is under construction. Unlike a standard mortgage that funds most or all loan proceeds at closing, construction funds are usually released through a series of draws as work progresses. After the home is completed, the construction balance is either converted into permanent financing or paid off with a new long-term mortgage.
Plan
Establish budget, land, builder and overall financing capacity.
Build
Construction lender advances funds through approved draws.
Complete
Final inspections and completion documentation confirm the home is finished.
Finance Long Term
The loan converts or a permanent mortgage pays off the construction balance.
You do not need to know which construction-loan structure you need yet.
The best starting point is where you are in the build and what you need the financing to accomplish.
I own my lot and I'm ready to build.
Your land position, construction budget, builder and completed-home value help determine how the construction and permanent financing can be structured.
See how owned land fitsI still need to buy the land.
Some construction structures can coordinate the land purchase and build, while other borrowers buy the lot first and finance construction afterward.
See the land-first questionsI want the easiest construction process.
For many custom builds, a local bank can be a very practical construction lender because it works directly with local builders, draws, inspections and changing construction timelines.
See our usual approachI want a one-time-close option.
Selected programs combine construction and permanent financing into one transaction, but they usually require more formal builder and project approval before closing.
See how one-time close worksWhy we often recommend a local bank for construction—and shop the permanent mortgage separately.
We do offer a one-time-close construction option. We just do not believe one-time close is automatically the best answer for every custom-home borrower.
Local bank handles the construction loan
Construction lending is operationally different from a normal mortgage. The lender has to manage builder documentation, draws, inspections, title updates, lien issues, construction changes and the project timeline.
Guarantee Mortgage handles the permanent financing
As the home approaches completion, we can compare eligible long-term mortgage options across wholesale lenders instead of automatically accepting only the construction bank's permanent loan.
The bank that makes construction easy is not automatically the lender you should keep for the next 30 years.
We usually want the construction lender to be excellent at construction, then compare the permanent mortgage on its own merits. If the local bank also has the best long-term option, great—we can compare it. If not, the permanent loan can pay off the construction balance at completion.
What the local-bank-to-permanent-mortgage process usually looks like
Establish your overall budget
Before finalizing plans, understand the approximate finished-home financing you can support, the cash or land equity available, and how much project contingency you want to keep.
Select the land, builder and plans
The construction lender will need enough detail to understand the property, proposed home, builder, contract price, budget and expected completed value.
Close the construction loan
The local bank establishes the construction facility and the initial funds are made available under its draw schedule and closing requirements.
Builder takes draws as work progresses
Funds are generally released in stages. The lender may require inspections, title updates, invoices, lien waivers or other documentation before each draw.
Prepare the permanent mortgage before completion
Do not wait until the construction line is about to mature. As completion approaches, Guarantee Mortgage can update income, assets, credit, appraisal requirements and permanent-loan options so the take-out financing is ready.
Finish the home and close the permanent loan
After required completion documentation and inspections are satisfied, the long-term mortgage funds and pays off the construction loan. You then make the regular payment required under the permanent mortgage.
How construction loan draws work
A construction lender generally does not hand the builder the entire project budget on day one. Funds are advanced as the project reaches defined stages.
1. Builder requests a draw
The builder submits the lender's required draw request and supporting documentation for work completed or eligible costs due.
2. Lender verifies progress
An inspection or other project review may confirm that the funded work has been completed and that the requested amount is consistent with the approved budget.
3. Funds are disbursed
Once requirements are satisfied, the lender releases the approved draw. The process repeats until construction is complete.
What the construction lender may monitor
How payments commonly work during the build
Many construction loans charge interest during the build based on funds that have actually been advanced rather than the entire approved project amount. Some programs are interest-only during the construction phase.
Do not assume every bank calculates payments the same way. Ask how interest is assessed, when payments begin, whether unused funds are charged, and what happens if the build runs longer than expected.
What happens to the construction loan when the home is finished?
If you used a construction-only loan or local construction line, the finished home still needs long-term financing. That is where the permanent—or “take-out”—mortgage comes in.
Permanent refinance / take-out loan
The new mortgage pays off the outstanding construction balance. Depending on the scenario, the permanent loan may be a conventional fixed-rate mortgage, jumbo loan or another eligible long-term structure.
Because the construction phase and long-term mortgage are separate, you can compare permanent lenders as the home approaches completion.
One-time-close conversion
With a true construction-to-permanent program, the construction financing and long-term mortgage are established in one transaction. After the build passes required completion reviews, the loan moves from its construction-phase payment structure into the permanent payment structure under that program.
Timing matters. If you plan to replace a local construction loan with permanent financing, start the permanent-loan process before the build is completely finished. That gives time for updated underwriting, appraisal/completion requirements, title work and closing without running into the construction loan's maturity date.
How a one-time-close construction-to-permanent loan works
A one-time-close program combines construction financing and the permanent mortgage into one overall loan structure. That can reduce the need for a second full mortgage closing, but it usually comes with a more formal builder and project-approval process before construction begins.
Prequalify the borrower
Establish the approximate total financing capacity before the final home design and land decisions are locked in.
Select a builder
The borrower chooses the builder or general contractor, then the program reviews the contractor for eligibility.
Approve builder + project
Selected programs review the construction contract, budget, plans, appraisal and other project documentation before clear-to-close.
Close before construction
After borrower, builder and project approval, the loan closes and the construction draw process can begin.
Build through managed draws
The construction administrator monitors items such as inspections, title, insurance, disbursements and lien documentation as work progresses.
Complete and convert
After required completion documentation and a satisfactory final inspection, the loan transitions into its long-term principal-and-interest phase under the program terms.
Typical project documentation
Why one-time close can be attractive
One-time-close program requirements, costs, construction periods, builder eligibility and permanent-loan terms vary by lender and are subject to change. We verify the current program before recommending it.
Local construction loan + permanent mortgage vs. one-time close
| What to compare | Local Bank Construction + Separate Permanent Loan | One-Time-Close Construction-to-Permanent |
|---|---|---|
| Number of financing phases | Two: construction financing, then permanent financing. | Construction and permanent financing are established within one overall loan structure. |
| Construction administration | Handled by the local construction lender; often relationship-driven and locally managed. | Handled under the selected program's formal construction-administration rules. |
| Builder approval | Bank-specific; local builder relationships can help. | Usually formal and completed before closing. Contractor history, licensing, insurance and background may be reviewed. |
| Ability to shop permanent financing later | Yes. The permanent mortgage can be compared as the build approaches completion. | More limited because the permanent structure is established as part of the original program. |
| Rate certainty at the start | The permanent rate is generally not established until the later mortgage is locked. | Depends on the program; the long-term structure is coordinated earlier, which can reduce some take-out uncertainty. |
| Flexibility when construction changes | Often a strength of a local relationship lender, though every bank has its own rules. | Changes must fit the program's approved budget, draw and project-review process. |
| Who it may fit | Borrowers who value local construction flexibility and want to shop the long-term mortgage separately. | Borrowers who value a single coordinated financing structure and are comfortable with the program's builder/project requirements. |
What if you already own the land—or still need to buy it?
If you already own the land
The construction lender will review how the land is titled, any debt secured by it, the land value, the construction budget and the expected completed value. Depending on the program, existing land equity may affect the amount of additional cash required.
Do not assume the land value automatically equals your usable down payment. The lender's appraisal, lien position and program rules determine how the equity is treated.
If you still need to buy the land
Some construction programs can coordinate the land acquisition with the construction financing, while other borrowers purchase the lot separately before the construction loan closes.
Before buying the land, make sure the proposed homesite works for the lender, builder and long-term mortgage—not just the building plans.
How is a rural construction loan different from a standard mortgage?
The basic financing concept is the same, but rural and acreage builds can add property questions that do not exist on a typical subdivision home.
Site + access
Road access, utilities, private well or septic systems, easements, surveys and site improvements can affect both construction and permanent-loan review.
Acreage + land value
Lenders can have different comfort levels with larger tracts, excess land value, agricultural use, outbuildings or unique rural properties.
Builder + marketability
The lender may look closely at whether the builder can complete the project and whether the finished home will be marketable in that location.
Before you close on raw land: send us the address or legal description, acreage, expected home size, rough build budget and intended use. A quick financing review before the land purchase can prevent an expensive mismatch later.
What should you compare between construction lenders?
The lowest advertised rate is not enough. A construction lender can be cheap on paper and frustrating in practice if its draw process or project rules do not fit the build.
Construction term
How long do you have to finish, and what happens if weather, permits, materials or labor extend the schedule?
Cash / equity requirement
How are the lot value, existing land equity, construction budget and completed value used in the lender's calculation?
Draw process
How often can the builder request funds, who orders inspections, and how quickly are approved draws released?
Interest during construction
Is interest charged only on drawn funds? When do payments begin? Is there any unused-line fee or other carrying cost?
Builder requirements
Does the lender approve the contractor, require specific insurance, experience, licenses, references or financial information?
Change orders
What happens when selections, materials or site work change the approved budget after construction starts?
Inspection + title costs
Ask about draw inspections, appraisal updates, title endorsements, recording, lien-waiver requirements and other construction administration costs.
Extension terms
If the home is not finished by maturity, is an extension available and what does it cost?
Permanent-loan obligation
Are you required to keep the permanent mortgage with that bank, or are you free to compare take-out financing elsewhere?

How the strategy works
The local bank makes the construction loan and administers builder draws throughout the project. As the home approaches completion, the borrower returns to Guarantee Mortgage. We update the mortgage qualification, compare eligible permanent-loan options, satisfy the completed-home requirements and close the long-term mortgage.
The permanent mortgage then pays off the construction balance. The borrower gets the benefit of a local construction relationship during the build without automatically committing to that bank's long-term mortgage pricing.
Construction financing problems that are easier to prevent than fix
Designing before setting a financing range
A beautiful plan that is materially above the borrower's realistic financing capacity creates expensive redesign work. Start with the financial guardrails.
Buying land without financing review
A lot can look perfect but create mortgage issues because of acreage, access, zoning, utilities, improvements or how much of the total value sits in the land.
Choosing a builder the lender will not approve
One-time-close and some bank programs require contractor approval. Verify the builder requirements before signing a non-refundable construction contract.
Using every available dollar in the base budget
Custom builds change. Keep enough liquidity for upgrades, overruns, moving expenses and items the lender may not finance.
Waiting until completion to start the permanent loan
Underwriting, appraisal completion, title and closing all take time. Begin the take-out financing early enough to avoid a maturity crunch.
Assuming the construction bank must be the permanent lender
That may be convenient, but convenience should be compared against the long-term rate, points, credits, term and total cost of other eligible mortgage options.
Permanent financing depends on the finished home and loan amount.

Texas construction loan FAQs
How do home construction loans work?
A construction loan provides short-term financing while a new home is being built. Funds are typically released to the builder in stages called draws. The lender may verify each stage through inspections and construction documentation. After the home is complete, the construction balance is either converted into permanent financing or paid off with a separate long-term mortgage.
What is the difference between a construction loan and a standard mortgage?
A standard mortgage finances an already completed property and generally funds at closing. A construction loan finances a project that does not yet exist in completed form, so the lender must also underwrite the plans, budget, builder, completed value and draw process. Construction financing is usually short term; the permanent mortgage is designed for the finished home.
Why might a local bank be easier for the construction phase?
Local banks often have established relationships with area builders, inspectors and title companies and can be experienced with construction draws and local project issues. That can make them a practical choice for the short-term construction phase. The best permanent mortgage can then be compared separately once the home is nearing completion.
Can Guarantee Mortgage handle only the permanent financing after construction?
Yes. A common strategy is to use a local bank for the construction loan, then have Guarantee Mortgage arrange the permanent mortgage that pays off the construction balance after the home is completed, subject to normal underwriting, appraisal, title and program requirements.
What is a one-time-close construction loan?
A one-time-close construction-to-permanent loan combines the construction phase and the long-term mortgage into one overall financing structure. The builder and project are typically approved before closing, funds are disbursed through draws during construction, and the loan transitions to its permanent-payment phase after required completion and final-inspection conditions are satisfied.
Do I make a full mortgage payment while the home is being built?
It depends on the construction loan. Many programs use interest-only payments during the build, often based on the amount of construction funds that have actually been advanced. Payment calculations, due dates and treatment of undrawn funds vary by lender, so they should be compared before choosing the construction loan.
How do construction loan draws work?
The approved construction budget is released in stages instead of all at once. The builder requests a draw for eligible completed work or costs, the lender verifies the request under its inspection and documentation rules, and the approved amount is disbursed. This repeats throughout the build.
Can I use land I already own toward a construction loan?
Potentially. The lender will review the land value, liens, title, construction budget and expected completed value. Existing land equity can be important to the financing structure, but the amount of equity a lender will recognize depends on the appraisal and program rules.
Can a construction loan include the land purchase?
Some construction programs can coordinate eligible land acquisition with the construction financing, while other borrowers purchase the lot before the construction loan. The right structure depends on the property, borrower, lender and timing. It is smart to review financing before committing to the land.
How does a construction loan for a rural home differ from a standard mortgage?
In addition to the construction project itself, a rural build may require more review of acreage, road access, utilities, well and septic systems, surveys, easements, site improvements, land value and marketability. Construction lenders and permanent mortgage lenders can have different property requirements, so both phases should be considered early.
How do I compare construction loan terms from different lenders?
Compare more than the interest rate. Review the construction term, down-payment or equity requirement, land treatment, draw speed, inspection process, builder rules, interest calculation, change-order flexibility, extension terms, construction administration costs and whether you are required to keep the permanent mortgage with that lender.
When should I start the permanent mortgage if I use a separate construction loan?
Start before the home is fully complete. The exact timing depends on the build and the construction loan's maturity date, but beginning early gives time for updated underwriting, appraisal or completion requirements, title work and closing so the permanent mortgage can pay off the construction balance without unnecessary pressure.
