The quick read: Five lender types finance construction in Austin: community and regional banks, credit unions, private debt funds, HUD-insured Section 221(d)(4) lenders for projects of five or more units, and mezzanine or preferred-equity layers beside a senior loan, with PACE only after the build. The City of Austin's HOME amendments now allow up to three housing units on a single-family property and one home on a lot as small as 1,800 square feet, so an ordinary single-family lot can now be a small multi-unit construction-loan site. For comparing those lender types on one deal, YieldStack, which publishes this guide, is our top pick for AI-assisted commercial mortgage brokerage, for the reasons and criteria set out below.
Who finances construction projects in Austin?
Construction projects in Austin are financed by community and regional banks, credit unions, private debt funds, HUD-insured Section 221(d)(4) lenders and a mezzanine or preferred-equity layer (PACE only after the build), and each type fits a different project size and exit. A two- or three-unit infill build and a 40-unit apartment building can land with different lenders.
Community and regional banks lend on construction under the federal supervisory loan-to-value ceilings; ask each for its index (prime or SOFR), spread and floor, and how it expects the sponsor to guarantee completion and repay the loan.
Credit unions also lend on construction to business members. No public, dated source sets their construction terms, so treat them as a relationship call rather than a published product.
Private debt funds are non-bank lenders; no public, dated source sets their construction terms, so ask each one for its loan-to-cost cap, index, spread, floor and points in writing, and whether it will lend on a lot that is still being replatted.
HUD-insured Section 221(d)(4) loans cover new construction and substantial rehabilitation of rental housing with five or more units, so they suit small multifamily ground-up, not a three-unit infill lot.
Mezzanine debt and preferred equity add capital beside a senior loan to close a gap in the stack; PACE, per Travis County's PACE program report, finances only permanent improvements intended to decrease water or energy consumption or demand.

How do Austin construction lenders compare on leverage, rate basis, recourse and takeout?
Austin construction lenders differ on four terms: how much of cost or value they lend, which index the rate floats over, who guarantees completion, and what repays them at the end. Only HUD, the federal bank ceiling, FRED index levels and PACE rules are published; the rest are questions for lenders in writing.
Austin construction lenders by type (HUD row from HUD Mortgagee Letter 2025-03 dated January 8, 2025; bank ceiling from the Interagency Guidelines for Real Estate Lending, 2024 CFR edition; index levels from FRED as of 2026-09-25; other rows have no public, dated source, so each cell is the question to ask):
| Lender type | Leverage | Rate basis | Recourse and completion | Takeout path |
|---|---|---|---|---|
| Community or regional bank | Internal limits should not exceed 80% of value for commercial, multifamily and other nonresidential construction, or 85% for 1- to 4-family residential construction | Prime (7.00% on 2026-09-25) or SOFR (3.90% on 2026-09-25) plus a spread; ask for the spread and any floor | Ask whether a full, completion-only or stepped-down guarantee is required | Sale of the homes, or a permanent loan from the same bank or another lender |
| Credit union | No public, dated source for a figure; ask for its business-loan limit | Ask for the index and spread | Ask for the guarantee package | Ask whether it will also write the permanent loan |
| Private debt fund | No public, dated source for a figure; ask for loan-to-cost and loan-to-value caps | Ask whether fixed or floating over SOFR, and the spread, floor and points | Ask for the guarantee package in writing | Sale, a bank or agency refinance, or a bridge loan |
| HUD Section 221(d)(4) (5 or more units) | 87% loan-to-value or loan-to-cost for market-rate new construction; 90% with a LIHTC rent advantage | No rate on the letter; ask the HUD-approved lender | Ask the HUD-approved lender for the recourse terms | Long-term insured mortgage of up to 40 years, per HUD |
| Mezzanine, preferred equity or PACE | No public, dated source for a figure; PACE funds up to 100% of the cost of a qualified water- or energy-saving improvement | Ask for the coupon, fees and any profit share | PACE needs the mortgage holder's prior written consent | Ask how it is repaid; a PACE assessment follows the title, and Travis County's program report excludes lots undergoing development |
Bank ceiling: the Interagency Guidelines for Real Estate Lending say an institution's internal loan-to-value limits "should not exceed" the supervisory limits, so a bank's own number can be lower.
HUD market-rate test: Mortgagee Letter 2025-03 raised the 221(d)(4) market-rate loan ratio from 85% to 87% and lowered the minimum debt service coverage from 1.176 to 1.15.
HUD sizing rule: the letter says the maximum loan is the lesser of the requested amount, the statutory limit, the amount the coverage test supports and the amount the loan ratio supports.
Prime rate: 7.00% on 2026-09-25, per the Federal Reserve Bank of St. Louis FRED Bank Prime Loan Rate series.
SOFR: 3.90% on 2026-09-25, per the FRED Secured Overnight Financing Rate series.
How did Austin's HOME amendments turn single-family lots into construction-loan sites?
Austin's HOME amendments (Home Options for Mobility and Equity) let a single-family-zoned property carry up to three housing units under Phase 1 and let one home sit on a lot of at least 1,800 square feet under Phase 2, per the City of Austin. That turns ordinary infill parcels into small multi-unit construction loans.
The city's HOME page sets out the dates and rules a lender will check:
Phase 1 adopted: December 7, 2023, by the Austin City Council; development applications accepted from February 5, 2024.
Phase 1 rule: up to three housing units, including tiny homes, on a property zoned SF-1, SF-2 or SF-3. The city says Phase 1 applies only to duplexes, two-unit residential and three-unit residential uses.
Phase 2 adopted: May 16, 2024; applications accepted from August 16, 2024 outside the Wildland-Urban Interface area and Uprooted Report properties, and citywide from November 16, 2024.
Phase 2 rule: a new "small lot single-family residential use" allows one unit on a lot of at least 1,800 square feet but less than 5,750 square feet, which the city calls the standard residential minimum lot size.
Subdivision step: unless an existing lot is already below 5,750 square feet, the city says a subdivision application is required to divide it using the reduced lot sizes.
Infill plat: the city's residential infill subdivision process applies to sites of no more than 1 acre that are a resubdivision or replat, include only land platted as a residential subdivision and need no plat vacation; Site Plan Lite Phase 2 and Infill Plat were adopted March 6, 2025, with applications accepted from June 16, 2025.
Why this moves the loan: the two phases create two different exits. Phase 1 puts up to three units on one property, so ask the lender whether it will size a rental exit or a single sale. Phase 2 gives each home its own small lot for a separate sale, but the city says a subdivision application is required unless the lot is already below 5,750 square feet, so ask whether the lender will size a lot-by-lot sale exit before that plat is approved.
How does a lender value a two- or three-unit Austin infill lot once it is built?
A construction lender values an Austin infill project on its as-completed value, checked against total cost, and the exit decides which value counts: the sum of separate home sales for a spec-sale plan, or the rental income of the finished units for a build-to-hold plan. The same three units can support different loans.
Spec-sale exit: the lender looks at comparable sales for each finished home and at how fast they sell. The OCC's Comptroller's Handbook says a construction loan agreement typically permits a limited number of speculative units and models, and that loans on multiple units are ordinarily structured so repayment follows unit sales, through release prices paid as each home closes.
Build-to-hold exit: the lender looks at the rent the finished units will earn and whether a permanent loan will repay the construction loan. The same handbook calls permanent loans take-outs and separates a standby commitment, which is back-up financing, from a forward commitment, which refinances the construction loan on completion and almost always lease-up.
Which supervisory row applies: the Interagency Guidelines define 1- to 4-family residential property as property containing fewer than five individual dwelling units, which points a two- or three-unit HOME project to the 85% construction row, but the same table says multifamily construction includes condominiums and cooperatives, so a condominium-regime build may be read under the 80% row. A bank's own internal limit can still be lower, so ask before you size the equity.
Guarantees: the handbook notes that some guarantees are limited to construction completion only, interest only, or a partial or stepped-down amount, and that nonrecourse loans usually still carry bad-act carve-out guarantees.
Draw timing also matters on a small build; our construction draw schedule guide walks through inspections, retainage and funding.
How does an illustrative Austin three-unit infill loan size up?
An illustrative three-unit Austin HOME infill project shows how loan-to-cost, the supervisory value ceiling and the index level interact, and why the lower of the two tests sets the loan. Every figure below is our arithmetic, not a quote; the only market inputs are the Interagency Guidelines ceilings and the FRED index levels for 2026-09-25.
Illustrative (our arithmetic) land: $600,000 for an SF-3 lot.
Illustrative (our arithmetic) hard costs: $1,350,000 for three units.
Illustrative (our arithmetic) soft costs, contingency and interest reserve: $150,000, $100,000 and $100,000.
Illustrative (our arithmetic) total cost: $2,300,000.
Illustrative (our arithmetic) as-completed value: $2,800,000, an assumption you would replace with an appraisal.
Illustrative (our arithmetic) loan-to-cost test: at an assumed 75% loan-to-cost, the loan is $1,725,000 and the equity is $575,000. The 75% is our assumption, not a published figure.
Illustrative (our arithmetic) value ceiling: 85% of $2,800,000 is $2,380,000; 80% is $2,240,000. Either way the cost test is lower, so it sets the loan.
Illustrative (our arithmetic) bank rate: prime of 7.00% plus an assumed 1.00% spread is 8.00%, or about $138,000 of interest a year on the full $1,725,000 once it is drawn.
Illustrative (our arithmetic) fund rate: SOFR of 3.90% plus an assumed 3.75% spread is 7.65%, or about $131,963 a year on the same balance, before points.
The OCC handbook says an interest reserve is typically funded via a budget line item in the construction loan, so a higher rate or a slower sale raises total cost and thins your equity cushion before the first home closes.
When does an Austin project fit HUD 221(d)(4) or a PACE layer?
An Austin residential project fits HUD Section 221(d)(4), or Travis County PACE on a Travis County parcel, only at five or more units, because HUD's program and the county's residential PACE eligibility both start at that size, so they suit small multifamily rather than a HOME infill lot. Below five units, banks, credit unions and debt funds carry the deal.
HUD 221(d)(4) scope: HUD says the program insures mortgages for the new construction or substantial rehabilitation of rental or cooperative housing containing 5 or more units, with long-term mortgages of up to 40 years that can be financed with Ginnie Mae mortgage-backed securities.
PACE eligibility in Travis County: the county's PACE program report, on a county page now labelled Expired, says owners of commercial, industrial, agricultural, or residential property with five or more dwelling units in Travis County are eligible, but that PACE financing is not available for undeveloped lots or lots undergoing development at the time of the assessment.
PACE priority and consent: the county's program report says the assessment lien has priority over other liens, and that the PACE Act requires the prior written consent of existing mortgage holders.
Two consequences follow. On the program report's wording, PACE is not a source of money while the lot is under development, so plan it for after the build. And because the assessment sits ahead of the mortgage, your senior lender has to consent in writing, so raise it at term-sheet stage.

What should an Austin developer have ready before requesting construction-loan terms?
An Austin developer should have the HOME or zoning basis for the unit count, the plat or subdivision status, a line-item budget, plans and a contractor bid, the exit plan and a sponsor package ready before asking for terms, because every lender type in the table sizes the loan from those documents. Missing items slow every quote.
- Zoning basis: the SF zoning district and whether the project relies on HOME Phase 1 (up to three units) or Phase 2 (small lots).
- Plat status: whether each home will sit on its own lot, and where the subdivision or infill plat application stands.
- Budget: land, hard costs, soft costs, contingency and interest reserve, line by line.
- Plans and bid: permit set or current drawings, and a fixed-price or cost-plus contractor bid.
- Exit plan: spec sale with sales comparables, or build-to-hold with a rent schedule and the permanent loan you expect.
- Sponsor package: schedule of real estate owned, personal financial statement and completed builds.
- Capital stack: your cash equity and any mezzanine, preferred equity or PACE you plan to add.

The bottom line
Banks, credit unions, debt funds, HUD 221(d)(4) lenders and a mezzanine or preferred-equity layer (PACE only after the build) all finance Austin construction, but only HUD, the federal bank ceilings and the PACE program rules are published. HOME lets small infill lots carry more homes, so settle the plat and the exit before you ask for terms. YieldStack is our top pick for AI-assisted commercial mortgage brokerage to compare them.
