One-Time-Close Construction Loans in Texas — Custom Builds in Austin & Hill Country

By Adam Styer, NMLS #513013 · Updated 2026-08-14

A one-time-close construction-to-permanent loan combines construction and permanent financing in one closing. Builder approval, plans, budget, draws, inspections, contingency funds, land equity, completion, rate and conversion terms, and borrower qualification vary by program and require review.

Most of my custom-build clients are self-employed business owners, partners in professional firms, or recently-liquidated founders. The right OTC structure pairs a strong construction loan with the right income documentation path — bank statement, asset depletion, K-1, or full-doc — so the underwriting is shaped around how the borrower actually earns. That's the difference between "we'll see if you qualify" at a big bank and a clean approval before the foundation is poured.

This page explains the questions to ask when comparing construction financing for a Texas custom build. Written lender, title, builder, and legal requirements control the transaction.

How an OTC Construction Loan Works, Step by Step

The exact sequence and timeline vary, but these are the major items borrowers should expect to coordinate.

1. Application and Pre-Approval

I underwrite the income, credit, assets, and lot value up front. For a Hill Country custom build, the income piece is often the deciding factor — tax-return income for an S-corp owner or partner rarely supports the loan amount the actual cash flow could carry. We pick the doc path that fits the borrower (full-doc, bank statement, asset depletion, or combined) and price the deal across multiple wholesale construction lenders.

2. Builder Approval and Project Package

The lender reviews the builder and project package. Required licensing, experience, insurance, financial information, references, contracts, plans, specifications, and budgets vary by lender and program.

3. Appraisal — As-Completed Value

A licensed Texas appraiser values the project as if it were already built, using plans and specs plus the lot. This number drives loan-to-value at conversion. If the as-completed appraisal comes in low, the loan amount is reduced — or the borrower brings cash to bridge the gap. We solve for this before contract signing whenever possible.

4. Single Closing

The initial closing covers the construction and permanent phases. Review the final loan, title, rate-lock, draw, completion, and conversion documents before signing.

5. Construction Phase — Milestone Draws

Funds release in milestone-based draws inspected by the lender at each stage — typical stages include foundation, framing and dry-in, mechanicals and rough plumbing, drywall and cabinets, and final completion. Each draw triggers a third-party inspection before funds release. You pay interest only on what's been drawn, not the full loan amount. The builder gets paid as work is verified complete.

6. Conversion to Permanent

At completion, the lender confirms the program's inspection, appraisal, occupancy, title, documentation, and other conversion conditions. The timing and permanent-payment terms follow the signed loan documents.

Building a Complete Hill Country Project Budget

Per-square-foot estimates are not a reliable substitute for a current, itemized project budget. The financing review should account for the lot, site work, engineering, utilities, permits, plans, construction, materials, finishes, allowances, change orders, contingency, interest, inspections, title, closing costs, and soft costs.

Hill Country sites can also involve septic, well, grading, rock excavation, utility extensions, access, fire-code, floodplain, and HOA or architectural-review questions. Confirm the applicable requirements, costs, and timeline with the builder and local professionals before relying on a financing estimate.

Self-employed borrowers may have full-documentation or alternative-documentation options such as bank statements or eligible assets. The documentation method and construction program must both be reviewed for the specific borrower and project.

OTC for Self-Employed and Complex-Income Borrowers

Most of my Hill Country custom-build clients are not on a W-2. They're S-corp owners, partners in professional firms, equity-comp executives, recently-liquidated founders, retired with significant brokerage assets, or some combination. Conventional construction lenders force these borrowers through the same tax-return wringer as a W-2 employee — and the math usually fails.

The right approach is to match the loan to how the borrower actually earns:

• Bank statement OTC: 12 or 24 months of deposits become qualifying income. Works for S-corp owners, 1099 contractors, and small-business owners whose tax returns deflate the real cash flow. See the bank statement loan guide for how the income math runs.
• Asset depletion OTC: for borrowers whose wealth lives in brokerage and retirement accounts rather than current income. The asset balance becomes a synthetic monthly income figure on the loan application. Detail is on the forthcoming asset depletion mortgage Texas page.
• K-1 / Form 1084 OTC: partners and S-corp owners with strong K-1 income but heavy depreciation and amortization can qualify via Fannie Form 1084 add-back analysis. Works on agency-eligible loans when the business passes liquidity tests.
• Combined-doc OTC: stacking W-2 income with bank statement, 1099, or asset depletion to hit qualifying income. Especially common for tech founders with W-2 base plus K-1 distributions or 1099 consulting income.
• High-net-worth borrowers: the structure is often pledged-asset or securities-backed combined with OTC. See the high-net-worth mortgage page for the wealth-side structures.
• Business owners: the forthcoming mortgage for business owners in Austin page covers structuring approaches when the borrower has multiple LLCs, holding companies, or layered ownership.

The construction underwriting is the same regardless of the income path. The income documentation is what changes — and that's where most lenders trip and where I spend most of my structuring time.

One-Time-Close Construction Loan FAQ — Texas

Quick Answers About One-Time-Close Construction Loans

What is a one-time-close construction loan?

A one-time-close construction loan combines the construction financing and permanent mortgage into one closing. It can reduce duplicate closings, but the borrower, builder, plans, budget, lot, and income documentation all need to be reviewed early.

Can self-employed borrowers use construction financing?

Yes, when the income documentation and construction file both fit program guidelines. Adam may compare full-doc, bank statement, asset depletion, K-1, or combined documentation paths for business owners building custom homes.

What should be reviewed before choosing a builder contract?

The loan structure should be reviewed against the lot, construction budget, builder package, appraisal approach, borrower income, assets, reserves, and timeline. A mismatch in any one of those can slow the file.
