Construction Loans in Hays County: Building in the Hill Country, Explained Plainly

One loan that pays your builder in stages, then converts to a regular mortgage when the house is done. I live in Dripping Springs — custom builds are my home market, and I'll make the financing the boring part.

In short

A construction-to-permanent loan finances a home build and the long-term mortgage in one package: the lender pays the builder in inspected stage draws during construction (with interest-only payments on drawn funds), then the loan converts to a regular mortgage when the home is complete — often with a single one-time closing.

How does a construction loan work?

A construction-to-permanent loan funds your home build and your long-term mortgage in one package. During construction, the lender releases money in draws — scheduled payments to your builder as each stage of work is completed and inspected — and you typically pay interest only on the funds drawn so far. When the home is finished, the loan converts to a regular permanent mortgage. Most of my clients use a one-time close structure: one loan, one closing, one set of closing costs. Qualifying involves you, your builder (lenders review and approve builders), and the project itself, with the appraisal based on the completed value of the home.

Key takeaways

A construction-to-permanent loan pays your builder in stages during the build, then converts to a regular mortgage when the home is complete.
A one-time close means one loan, one closing, one set of closing costs — usually the better structure for custom builds, but we compare both.
During construction you typically pay interest only on the funds drawn so far, so payments start small and grow with the house.
Lenders underwrite three things: you, your builder, and the project — builder approval and a realistic budget matter as much as your credit.

The Hill Country is a build market. People come to Dripping Springs, Wimberley, and Boerne for land and views you can't buy from a production builder — so they build. A construction-to-permanent loan finances the whole journey: it pays your builder in inspected stages while the house goes up, then converts into a normal mortgage when it's finished, often with a single closing. It's a high-value, high-trust transaction, and it rewards having one experienced person accountable from first conversation to final draw. I've structured complex files since 2003, and I build alongside this market every day — literally from inside it.

Construction-to-Permanent, in Plain English

A construction loan sounds complicated, so let me strip it down.

When you build a home, you need two things: money to pay the builder while the house goes up, and a normal mortgage once it's finished. A construction-to-permanent loan handles both in one package. During the build, the loan pays your builder in stages as work is completed. When the home is finished, the loan converts into a regular mortgage — the kind you'd have if you'd bought an existing house.

The version most of my clients use is the one-time close: a single loan, a single closing, a single set of closing costs, covering both the construction phase and the permanent mortgage. The alternative — a standalone construction loan followed by a separate permanent mortgage, with two closings and two sets of costs — still makes sense in some situations, and we'll compare both. But for most custom builds, one closing beats two.

During construction, you typically make interest-only payments, and only on the money actually drawn so far — not the full loan amount. Your payments start small when the slab is poured and grow as the house does.

Why the Hill Country Is a Construction Market

I live in Dripping Springs, so I watch this market from inside it. The Texas Hill Country — Dripping Springs, Wimberley, Boerne, and the corridors around them — is one of the strongest custom-build markets in the state, and for a simple reason: the thing people move here for is land. Acreage, views, room for a shop and a garden and whatever else you've been putting off. You can't buy that off a production builder's shelf, so people build.

Boerne and the western Hill Country are growing the same way. These are high-value builds on unique lots, which makes them high-trust transactions: you're committing to a large number for a house that exists only on paper. That's exactly the kind of file where you want one experienced person accountable from the first conversation to the final draw — not a rotating call center queue.

What You Need Before You Apply

A construction loan underwrites three things: you, your builder, and the project. Come to the table with:

  • The land. Owned already or part of the deal — land you own can often contribute equity toward the project.
  • A builder. Lenders review and approve the builder — experience, references, financials. A strong builder makes your loan easier; an unproven one makes it harder.
  • Plans and specs. The drawings and specifications for what you're building.
  • A detailed budget and contract. The cost breakdown the appraisal and the draw schedule will be built on.
  • A contingency cushion. Builds run over — materials, weather, change orders. We plan for it on paper before it happens in the field, so an overage is an inconvenience instead of a crisis.

The appraisal is based on the completed value of the home — what the finished house on that lot will be worth, based on your plans and budget.

How Draws Work

Construction funds are released in draws — scheduled disbursements tied to completed stages of work. Foundation, framing, mechanicals, finish-out: at each stage, an inspection confirms the work is done, and the lender releases the money for it. Your builder gets paid for work actually completed, which protects everyone — including you. I'll walk you and your builder through the draw schedule before closing so there are no surprises about how and when money moves.

The Questions I'll Help You Answer First

  • Does the total project — land, build cost, contingency — fit the completed value the market supports? (Building more house than the land justifies is the classic Hill Country mistake.)
  • Is the budget real? A thin budget that triggers change orders costs more than an honest one.
  • One-time close or two? We'll run both structures against your situation.
  • What's the monthly picture — during the build and after conversion? It's not the cost of the home, it's the cost of the home on a monthly basis. That's doubly true when you're carrying rent or an existing mortgage during construction, and we'll map that carrying period honestly.

Building a custom home is the largest act of trust most families ever put on paper. My job is to make the financing the most boring part of it. Strategy always wins.

Is this loan right for you?

Who it's for

  • Families building custom homes in the Hill Country — Dripping Springs, Wimberley, Boerne, and beyond
  • Landowners ready to build on a lot they already own
  • Move-up buyers who can't find what they want on the resale market
  • Anyone who wants one accountable person managing a high-trust, high-value transaction

Who it may not fit

  • Buyers purchasing a completed home from a builder's inventory — that's usually a standard purchase loan
  • Projects without an approvable builder or a realistic, documented budget — those need fixing first

Pros and cons

Pros

  • One-time close options mean one closing and one set of closing costs
  • Interest-only payments during construction, and only on funds drawn
  • Land equity can often reduce the cash you need to bring
  • Draw inspections keep builder payments tied to completed work

Trade-offs to weigh

  • More moving parts than a standard purchase — builder approval, plans, budget, draws
  • Cost overruns beyond the contingency typically come out of pocket
  • You may carry rent or an existing mortgage during the build

Frequently asked questions

What's the difference between a one-time close and a two-time close?

A one-time close is a single loan covering construction and the permanent mortgage — one closing, one set of closing costs, with the conversion built in. A two-time close is a standalone construction loan followed by a separate permanent mortgage when the home is done, meaning two closings and two sets of costs, but a chance to restructure the permanent loan at completion. For most custom builds, one close wins on cost and certainty, but I'll run both structures against your situation.

What do I pay during construction?

Typically interest-only payments, calculated only on the money drawn so far — not the full loan amount. When the foundation is poured, you're paying interest on a small balance; as framing, mechanicals, and finish-out draw more funds, the payment grows. We'll map that carrying period honestly, especially if you're paying rent or an existing mortgage at the same time, so there are no surprises mid-build.

I already own my land. Does that help?

Usually, yes. Land you own free and clear — or with substantial equity — can often count toward your equity in the total project, reducing or sometimes eliminating the cash you need to bring. The appraisal looks at the completed value of the house on your lot, and your land is part of that value. Bring me the land details early; it changes the whole structure of the loan.

Does my builder have to be approved by the lender?

Yes — lenders review the builder's experience, references, and financial standing before approving the project. This protects you as much as the lender: the draw money only performs if the builder does. A strong, established builder makes your loan smoother; an unproven one adds friction. If you're still choosing a builder, talk to me first — I can tell you what lenders will want to see before you sign a construction contract.

What happens if the build goes over budget?

It happens — weather, materials, change orders. The plan for it is made before closing, not during framing: we build a contingency reserve into the loan budget so overruns have a funded home. Significant overages beyond contingency typically come out of pocket, which is why I pressure-test the budget's realism up front. An honest budget with cushion beats an optimistic one that unravels in month four.
