Commercial construction projects under $20M in Houston are financed by four lender types — banks, debt funds and private credit, HUD's 221(d)(4) program for apartments, and SBA 504 for owner-occupied buildings — and every one of them sizes the loan on total cost rather than finished value. Submit a Houston construction deal to see which are quoting now.
Most of those deals do not fail at the construction loan. They fail eighteen months later, when the takeout lender sizes the permanent loan on income and the number comes back smaller than the construction balance.
Who finances commercial construction projects in Houston, Texas under $20M?
Four lender types finance Houston commercial construction under $20M: regional, community and national banks; debt funds and private credit; HUD through the 221(d)(4) program for apartments; and SBA 504 for owner-occupied buildings. Banks price cheapest but want recourse and deposits. Debt funds lend higher, non-recourse, at a premium. HUD is slowest and cheapest.
| Lender type | Best fit under $20M | Leverage (illustrative) | Recourse | Tradeoff |
|---|---|---|---|---|
| Banks | Multifamily, retail, industrial, owner-user | 60-70% of cost | Full or partial | Lowest spread; wants deposits |
| Debt funds, private credit | Higher leverage, speed | 70-80% of cost | Non-recourse beyond carve-outs | Several hundred bps wider |
| HUD 221(d)(4) | New or substantially rehabilitated apartments | Program-set | Program-set | Slow; program rules set the terms |
| SBA 504 (a Certified Development Company plus a senior lender) | A building the business will occupy | Program-set | Owner guarantees typical | No rental real estate held for investment |
Life insurance companies appear mainly on larger deals, so for a mid-sized investor deal the practical split is banks versus debt funds, and it turns on recourse. A regional bank typically prices at a spread over SOFR in the low-to-mid 300s with repayment guarantees; a debt fund drops the guarantee for a wider spread. You are buying balance-sheet protection with rate. Terms are quoted deal by deal, not published.
Three September 2026 readings set the frame. The Federal Open Market Committee raised the federal funds target range by a quarter point to 3-3/4 to 4 percent on September 16, 2026. According to FRED, SOFR, the base index under most floating-rate construction debt, was 3.85% on the 2026-09-21 observation date, and the Bank Prime Loan Rate, which some banks use for smaller construction lines, was 7.00% on the 2026-09-18 observation date, having risen from 6.75% on 2026-09-16. A bank quote at an illustrative 325 basis point spread over SOFR lands near 7.1% before fees. CBRE data reported by CRE Daily put alternative lenders — debt funds and credit companies — at 38% of non-agency loan closings in the second quarter of 2026, up from 34% a year earlier, so a debt fund is a realistic second call rather than a fallback. Current benchmarks are on the rates page.
Houston-specific factors move the credit too: submarket absorption, whether the site sits in a mapped floodplain (settled by FEMA's National Flood Hazard Layer, not the seller) or triggers post-Harvey stormwater detention, the contractor's local track record, and the property insurance quote, which flows into stabilized net operating income. The Houston market picture sets the absorption case a lender will test.
How is a Houston construction loan sized?
A construction lender sizes the loan against the total development budget rather than the finished value of the building, and advances 60-80% of that budget as loan-to-cost: banks at the low end, debt funds at the high end. The sponsor funds the remaining equity first, before any loan proceeds are drawn, so the lender's dollars go in last.
Total development cost is the denominator, and it includes items sponsors routinely leave out of early models:
- Land and closing costs, at basis, not at appraised value.
- Hard costs, under a guaranteed maximum price contract with a general contractor the lender has vetted.
- Soft costs — architecture, engineering, permits, impact fees, legal, financing fees.
- Contingency, typically 5-10% of hard costs. A lender will size it for you if you understate it.
- Capitalized interest reserve, funded inside the loan to service the debt through construction and lease-up, since the property produces no income until it delivers.
The same cost-based sizing applies to apartments, retail, industrial and owner-user buildings; see the construction loan overview.
How do Texas lien law and Texas taxes change a Houston construction loan?
Texas lien law changes a Houston construction loan through priority and draws: under Texas Property Code Chapter 53, a mechanic's lien dates from the visible start of work or delivery of materials, so lenders record their deed of trust before anything happens on site and fund each draw against statutory lien waivers and a 10% retainage holdback.
- Priority (§53.123, §53.124): a mechanic's lien does not affect a mortgage already on the land when the lien's inception occurs, and inception is the commencement of construction or delivery of materials visible on the land. A deed of trust recorded before visible work keeps its place, which is why lenders inspect the site before closing.
- Retainage (§53.101): the owner must reserve 10 percent of the contract price, or of the value of work done, during the work and for 30 days after completion. A lender's construction draw schedule typically mirrors that holdback.
- Claim deadlines (§53.052, §53.056): on non-residential projects, an original contractor files its lien affidavit by the 15th day of the fourth month after the month its work was completed, terminated or abandoned; a subcontractor or supplier sends notice of an unpaid claim by the 15th day of the third month after the month it provided the labor or materials.
- Lien waivers (§53.281, §53.284): a waiver is unenforceable unless it substantially complies with a statutory form, so each draw request should carry conditional progress waivers in that form.
Taxes matter less than sponsors expect. Article 8, Section 24-a of the Texas Constitution bars a tax on the net incomes of individuals, including partnership income, which helps a sponsor's after-tax return but not the loan, because lenders size on net operating income. The entity-level franchise tax carries a $2,650,000 no-tax-due threshold and a 0.75% rate for entities other than retail or wholesale for 2026 and 2027 reports. The Texas line that moves net operating income is property tax, underwritten at the completed building's value.
What do the numbers look like on a $12M construction loan for 64 units?
On an illustrative 64-unit Houston deal carrying $17,000,000 of total development cost, a $12,000,000 construction loan is 70.6% of cost and leaves $5,000,000 of sponsor equity. Roughly $1,000,000 of that loan is capitalized interest rather than construction money, because the property earns nothing until units deliver.
The arithmetic, line by line:
| Line | Amount | Note |
|---|---|---|
| Total development cost | $17,000,000 | ~$265,600 per unit |
| Construction loan | $12,000,000 | 70.6% of cost |
| Sponsor equity | $5,000,000 | 29.4%, funded first |
| Interest reserve (inside loan) | ~$1,000,000 | ~55% average outstanding, 24 months, ~7.5% all-in assumed |
| Stabilized gross potential rent | $1,497,600 | 64 units at $1,950/month |
| Less vacancy and collection loss, 7% | $1,392,768 | effective gross income |
| Less operating expenses, ~38% | $863,516 | stabilized NOI |
| Value at a 5.00% cap rate | $17,270,000 | a $270,000 margin over cost |
The rent, vacancy, expense and cap-rate lines are assumptions; substitute your own. Run them at your numbers and the shape holds: a competently executed deal clears its own cost by a low single-digit margin. There is no room for a 10% budget overrun, and that is before the refinance test below.
What is the refinance gap, and why does it kill Houston deals?
The refinance gap is the difference between the construction loan balance at maturity and the permanent loan that the stabilized rental income will actually support. Construction debt sizes on cost; permanent debt sizes on DSCR. When income-based sizing comes in below the construction balance, the sponsor must fund the difference in cash.
The 10-year Treasury was 5.01% on the 2026-09-18 observation date according to FRED, so a permanent multifamily rate of 6.50% — roughly 150 basis points over that base — is an illustrative test, not a quote. CBRE data reported by CRE Daily put the average all-in mortgage rate in the second quarter of 2026 at 5.7%, a quarterly average; at that rate the same net operating income supports roughly $9,900,000 of permanent debt and the shortfall narrows to about $2,100,000. The same brief put second-quarter 2026 multifamily originations at 63.3% LTV, down from 65.8%, with debt service coverage across CRE lending averaging 1.43x — so a 1.25x sizing floor produces more debt than the average loan actually closing, and the gap computed below is a floor rather than a worst case.
Run the takeout on the same deal. Stabilized NOI is $863,516. A permanent lender underwriting to a 1.25x DSCR minimum will allow annual debt service of $863,516 ÷ 1.25 = $690,813. At 6.50% on a 30-year amortization, that debt service supports approximately $9,100,000 of permanent debt.
Against a $12,000,000 construction balance, that is a $2,900,000 gap — cash the sponsor must write at maturity, or cover with a supplemental, a rate buydown, or a sale. Retail, industrial and owner-user takeouts run the same income test.
Try refinancing the full $12,000,000 at the same 6.50% over 30 years: debt service is about $910,200 a year, against $863,516 of NOI. That is a 0.95x DSCR — the property does not cover its own debt service, and no permanent lender funds it. The construction loan was never wrong; it was sized on a different variable.
Three things close the gap: more equity in the capital stack, a rate environment that cooperates at maturity, or rents that beat the underwriting. Only the first is within your control; a forward commitment or construction-to-permanent facility locks the smaller takeout but does not conjure the missing cash. That is the argument for testing the takeout at several rate and cap-rate scenarios in the underwriting calculator before the construction loan is signed.
What documents does a Houston construction lender need?
A Houston construction lender needs a complete package before it will quote seriously: the total development budget, a guaranteed-maximum-price contract, the general contractor's résumé and financials, plans and permit status, an absorption or market study, an appraisal with as-complete and as-stabilized values, and the sponsor's financial statement and track record.
Houston adds a flood determination, the detention plan and an insurance quote. The process runs in three steps: indicative terms on the package, a signed term sheet, then third-party reports — appraisal, environmental, plan and cost review, survey and title — before closing. Full credit approval commonly runs several weeks, because each report has its own lead time.
How do you get competing construction quotes without calling twenty lenders?
Construction lending appetite is narrow and moves quarter to quarter — a bank that funded a 64-unit Houston deal last spring may be out of the asset class this quarter, and there is no public list of who is in. Sequential calls surface that the slow way. Matching a packaged deal against current program criteria surfaces it in one pass.
That is broker work. YieldStack is a commercial mortgage brokerage, not a lender: one submission is pre-screened for bankability, matched at the program level, and routed only to the lenders whose current mandate covers ground-up construction at your size, property type and location. Competing terms come back side by side rather than one at a time. Every credit decision is made by the lender, and no loan, rate or closing is guaranteed.
- Upfront cost: Zero upfront — it costs nothing to submit a deal and review offers.
- Broker fee: 0.50–1.00% of the loan amount, paid only at closing.
- Speed: median offer in under an hour, from an institutional lender.
- Matching: 5–8 matched lenders per deal, drawn from 20,000+ loan programs.
Construction needs a packaged credit narrative — the GC's résumé, the absorption case, the takeout analysis — because a lender's screen rejects an incomplete story before a human reads it. That packaging is broker work, and it separates a deal that gets quoted from one that gets ignored.
What is the bottom line on Houston construction financing under $20M?
Houston construction debt under $20M comes from banks at lower cost with recourse, debt funds at higher leverage without it, and HUD or SBA 504 where they fit. Size on cost, record before site work to hold Texas lien priority, and model the takeout on income: on a $12,000,000 loan against $863,516 of NOI, the gap is nearly $3,000,000.
