Ground-Up Construction Loans in San Antonio: Spec Build and BTR Financing

San Antonio issued over 1,800 new residential building permits in the first two months of 2026, ranking it 10th nationally for new home construction concentration, according to CultureMap San Antonio citing ConsumerAffairs research. The metro added approximately 30,000 new residents in 2024 and recently surpassed 2.8 million in total population, fed by steady in-migration from Austin, Dallas, California, and other higher-cost markets.

LendSure Home Loans offers ground-up construction financing for spec builds and build-to-rent projects in Texas, with no tax returns, no W-2s, and no personal income analysis required. For investment transactions, you can walk our team through your project details with our team before committing to a full application.

Where San Antonio Builders Are Finding Opportunity

The north and northwest corridors along Loop 1604 and Highway 281 are the most active for large-scale national builders, who are delivering hundreds of new homes per quarter with rate buydowns and closing credits, according to Propcash’s 2026 San Antonio market analysis. That level of incentive competition makes spec-build margins tighter for smaller operators in those areas.

The more defensible opportunities fall elsewhere. The south side’s Brooks District carries entry-level price points of $180,000 to $240,000 and the highest investor activity in the metro. Tobin Hill and Southtown see consistent demand from urban buyers in a supply-constrained infill environment. Cibolo and military-adjacent corridors near Randolph AFB benefit from a tenant base that generates steady occupancy regardless of broader market conditions.

Spec Build vs. Build-to-Rent in San Antonio’s 2026 Market

Spec builds priced between $250,000 and $350,000 align with where buyer demand concentrates and where San Antonio’s 97.8% sale-to-list ratio holds. BTR projects benefit from a multifamily pipeline thinning sharply in 2026, with apartment completions forecast to drop 21% annually per Northmarq’s San Antonio multifamily outlook — less new supply entering the rental market supports vacancy tightening and rent recovery.

How LendSure’s Ground-Up Construction Program Works

LendSure’s Ground-Up Construction loan is a business-purpose product for 1 to 4 unit spec builds and BTR projects, closing in an LLC or S-Corp. No personal income documentation is required. Texas’s non-judicial foreclosure framework supports favorable loan terms, and San Antonio’s permit review timeline of 3 to 18 days per the City of San Antonio Development Services Department means projects can move efficiently from approval to groundbreaking.

Standard terms run 12 or 18 months, interest-only, with a 24-month option on exception. No prepayment penalty applies.

Leverage Structure

ComponentMaximum
Lot reimbursement (owned lot)Up to 60% of purchase price
Construction budgetUp to 85% (up to 100% case-by-case)
Blended loan-to-costNot to exceed 85%
Loan-to-ARVNot to exceed 70%

If you own the lot free and clear, LendSure can return up to 60% of what you paid at closing — useful on south side and infill acquisitions where land was secured at a favorable basis. LendSure can also finance up to six months of interest-only payments into the loan as an interest reserve, covering monthly obligations during the build phase.

LTC and LTV: How the Loan Gets Sized

Both metrics apply simultaneously — the lower of the two controls the final loan amount.

Loan-to-Cost (LTC)

LTC compares the loan to total project cost: lot, construction budget, and soft costs like permits and plans. LendSure finances up to 85% of total cost. Land you already own counts in the basis, reducing your required equity contribution on deals where you control the lot.

Loan-to-Value (LTV)

LTV compares the loan to the completed appraised value. LendSure’s construction loans are capped at 70% of ARV. In San Antonio’s current market, where homes sell at approximately 97.8% of list and days on market average 55, ARV modeling needs to reflect actual comparable sales — not the appreciation pace of 2021 to 2023.

What LendSure Looks for in a San Antonio Construction Deal

Location fit. LendSure finances infill construction in urban and semi-urban areas with a population base of at least 50,000. Utilities must be at the curb and permits must be ready or near-ready at closing. San Antonio’s established neighborhoods and growing outer corridors generally meet this standard.

Experience. Completed builds verified through public records under the borrower’s name or LLC. First-time builders can qualify with more conservative leverage and must use a General Contractor. Builders with six or more completed projects may qualify for the highest tier. 

Liquidity. Minimum liquid or near-liquid assets of approximately $200,000 required, with more expected on larger projects. Six months of interest-only reserves must be verified and can be financed into the loan.

Exit clarity. Spec builds need a documented sale target. BTR projects need rental projections and a stabilization timeline tied to the submarket. The DSCR refinance path should be modeled before closing, not improvised after.

From Construction to Rental: The DSCR Exit

For BTR projects, the construction loan covers the build phase. Once the property is leased and generating documented income, it refinances into a DSCR loan qualifying on rental income rather than personal income. LendSure accepts DSCR ratios as low as 0.75 (exceptions to 0.25) and finances up to $3 million for 1 to 4 unit properties. If the construction loan was with LendSure, no seasoning is required and the construction-phase appraisal can typically be reused.

San Antonio’s multifamily vacancy is expected to tighten by 90 basis points in 2026 as the post-2022 delivery cycle compresses. For BTR builders in military corridors and transitional neighborhoods, that tightening improves the lease-up assumptions behind the DSCR refinance.

Frequently Asked Questions

What is a ground-up construction loan, and how does it work in Texas? 

A ground-up construction loan is a short-term, interest-only loan that finances new residential development from the ground up. In Texas, it closes in an LLC or S-Corp, requires no personal income documentation, and releases funds in draws tied to completed work. Texas’s non-judicial foreclosure framework generally supports more favorable loan terms than states with longer foreclosure timelines.

What is the difference between a spec build and a build-to-rent project? 

A spec build is constructed to sell; the loan is paid off at closing from sale proceeds. A build-to-rent project is constructed to hold as a rental, with the construction loan refinancing into a DSCR permanent loan once the property is leased and stabilized. The financing structure during construction is largely the same — the exit path is what differs.

Which San Antonio submarkets are best suited for ground-up development? 

It depends on strategy. Spec builders find defensible margins in infill areas like Tobin Hill, Southtown, and south-side corridors where supply is constrained and national builder competition is lower. BTR projects perform well in military-adjacent areas like Cibolo and Brooks District, where rental demand is structurally supported.

How much equity is required? 

LendSure finances up to 85% of total project cost, capped at 70% of completed appraised value. The remaining portion is the equity contribution. Owning the lot free and clear can reduce upfront cash requirements significantly, as LendSure can return up to 60% of the lot’s purchase price at closing.

Can I refinance into a rental loan after the build is complete? 

Yes. Once the property is leased, LendSure can refinance into a DSCR loan qualifying on rental income. If the construction loan was with LendSure, no seasoning is required and the construction-phase appraisal can typically be reused.

How long does San Antonio’s permitting process take? 

Plan review for new home construction in San Antonio typically runs 3 to 18 days, depending on project scope, with expedited review available. LendSure requires permits to be ready or within approximately 25 days of final sign-off at closing. Builders who have permits in hand move through the process most efficiently.

Do I need prior construction experience to qualify? 

No, but experience determines leverage tier. First-time builders qualify with more conservative terms. Three or more completed ground-up projects in the last three years unlocks the highest leverage. Experience must be verifiable through public records under your name or your LLC.
