Financing a 10–30 unit apartment building in Houston puts you in the $1–5M loan band, and that band has its own rules. The building's net operating income carries the loan — your personal income matters far less than it would on a duplex. Four lender channels compete for this paper, and three sizing tests decide how much you actually get. Below, a 24-unit Houston deal is sized end to end using September 2026 market inputs.
What lenders actually finance a 10–30 unit building in Houston?
Four channels compete for Houston multifamily loans between $1 million and $5 million, and they price and size the same building very differently. Agency small-loan programs offer the longest fixed terms and non-recourse execution. Banks and credit unions move fastest on recourse paper. Debt funds cover transitional assets that stabilized programs reject.
The channel you pick matters more than the eighth of a point you negotiate, because each one applies a different sizing test first and arrives at a different number on the same building.
Table 1: financing channels for a $1–5M Houston multifamily loan
| Channel | What it optimizes for | Recourse | Where it breaks down |
|---|---|---|---|
| Channel Agency small-loan program | What it optimizes for Long fixed term, non-recourse, lowest all-in rate | Recourse Non-recourse with standard carve-outs | Where it breaks down Needs stabilized occupancy and clean trailing financials |
| Channel Regional or community bank | What it optimizes for Speed, flexibility on odd assets, relationship pricing | Recourse Usually full or partial guarantee | Where it breaks down Shorter terms, balloon risk, deposit requirements |
| Channel Credit union | What it optimizes for Patient capital for owner-operators | Recourse Often partial guarantee | Where it breaks down Membership and geographic limits |
| Channel Debt fund / bridge lender | What it optimizes for Sub-stabilized occupancy, deferred maintenance, fast close | Recourse Partial ("bad boy") guarantee | Where it breaks down Interest-only, floating, and expensive to carry |
The occupancy line: stabilized programs set a minimum occupancy, and a period it must be held, before they will quote long-term fixed debt; ask each lender for its test. Below that, you are in bridge territory until you lease up.
The unit-count line: 10–30 units is squarely inside small-balance territory. It is too small for institutional attention and too large for residential underwriting, which is exactly why borrowers in this band get quoted so inconsistently.
Sizing the loan: the three tests that decide your proceeds
Every lender in this band runs the same three calculations, and the smallest of the three answers becomes your loan amount. Loan-to-value caps proceeds against the appraised value. Debt service coverage caps them against the payment. Debt yield caps them against net operating income alone, ignoring both rate and amortization entirely.
Most first-time buyers only ever hear about the first two. Debt yield is the one that quietly cuts proceeds, because it is the lender's answer to "what return do I earn if I foreclose tomorrow?" It has no rate input, so it does not improve when rates fall.
Here is where the market actually cleared in the most recent full quarter, per CBRE's Q2 2026 lending report:
Market LTV: multifamily loans closed at an average 63.3% loan-to-value in Q2 2026, down from 65.8% a year earlier (CBRE).
Market DSCR: the average closed debt service coverage ratio rose to 1.43x (CBRE).
Market debt yield: the average debt yield improved to 10.2% (CBRE).
What that pattern means: CBRE also reported multifamily loan spreads tightened 15 basis points year over year to 162 bps, while LTVs fell. Lenders are competing on price, not leverage. You will be offered a sharper rate and a smaller loan than you would have gotten a year ago.
If you want the coverage math itself broken down step by step, the Houston DSCR loan guide walks the calculation on smaller Houston assets.
Worked example: sizing a 24-unit Houston building at $2.45M
Here is the full arithmetic on a 1970s-vintage 24-unit building priced at $2.45 million, or $102,083 per unit, in a workforce-housing Houston submarket. Every assumption below is stated so you can swap in your own numbers. The result is the figure that surprises most first-time small-multifamily buyers in this band.
Table 2: 24-unit Houston example — trailing-12 operating summary
| Line item | Annual | Per unit | Note |
|---|---|---|---|
| Line item Gross potential rent | Annual $360,000 | Per unit $15,000 | Note 24 units at $1,250/month |
| Line item Vacancy and credit loss (8%) | Annual ($28,800) | Per unit ($1,200) | Note Tighter than the metro average |
| Line item Effective gross income | Annual $331,200 | Per unit $13,800 | Note |
| Line item Property taxes | Annual ($62,000) | Per unit ($2,583) | Note Underwritten at reassessed value |
| Line item Insurance | Annual ($28,800) | Per unit ($1,200) | Note Gulf Coast wind exposure |
| Line item Payroll and contract services | Annual ($24,000) | Per unit ($1,000) | Note |
| Line item Repairs and maintenance | Annual ($21,600) | Per unit ($900) | Note |
| Line item Owner-paid utilities | Annual ($19,200) | Per unit ($800) | Note |
| Line item Management fee (4% of EGI) | Annual ($13,248) | Per unit ($552) | Note |
| Line item Administrative and marketing | Annual ($7,200) | Per unit ($300) | Note |
| Line item Replacement reserves | Annual ($6,000) | Per unit ($250) | Note Lender-required escrow |
| Line item Total operating expenses | Annual ($182,048) | Per unit ($7,585) | Note 55.0% expense ratio |
| Line item Net operating income | Annual $149,152 | Per unit $6,215 | Note 6.09% cap rate on $2.45M |
Now run the three tests against that $149,152 of NOI, assuming a 6.40% fixed rate on 30-year amortization (an annual constant of 7.506%) and a 1.25x coverage floor.
Table 3: 24-unit Houston example — which sizing test binds
| Test | Assumption | Maximum loan | Implied LTV | Implied DSCR | Implied debt yield |
|---|---|---|---|---|---|
| Test Loan-to-value | Assumption 75% of $2.45M | Maximum loan $1,837,500 | Implied LTV 75.0% | Implied DSCR 1.08x | Implied debt yield 8.1% |
| Test Debt service coverage | Assumption 1.25x at 6.40%, 30-yr am | Maximum loan $1,589,700 | Implied LTV 64.9% | Implied DSCR 1.25x | Implied debt yield 9.4% |
| Test Debt yield | Assumption 10.2% market average | Maximum loan $1,462,300 | Implied LTV 59.7% | Implied DSCR 1.36x | Implied debt yield 10.2% |
| Test Binding constraint | Assumption Lowest of the three | Maximum loan $1,462,300 | Implied LTV 59.7% | Implied DSCR 1.36x | Implied debt yield 10.2% |
The headline number: the 75% LTV in the marketing brochure produces a loan that fails coverage outright at 1.08x. The real proceeds are $1,462,300, which means roughly $987,700 down plus closing costs — call it $1.05M of cash into a $2.45M building.
The lever that actually moves money: the gap between the debt-yield answer and the DSCR answer is $127,400 on this one deal. That gap is not negotiated. It is a function of which lender's screen you land on, which is the entire argument for running one file past several channels at once instead of calling one bank.
What raises proceeds honestly: every $10,000 of verified NOI adds roughly $98,000 of loan capacity at a 10.2% debt yield. Fixing a vacancy line or a mis-billed utility recovery is worth more than a rate negotiation.
Where the rate actually comes from right now
A Houston multifamily quote in September 2026 is built from a benchmark rate plus a credit spread, and both halves are publicly observable. Fixed-rate loans price off the Treasury curve; floating-rate bridge debt prices off SOFR. Knowing both numbers lets you tell a competitive quote from a lazy one before you sign anything.
10-year Treasury: 4.75% as of August 31, 2026, per the Federal Reserve Bank of St. Louis (FRED series DGS10).
SOFR: 3.66% as of September 1, 2026, per FRED — down from 3.68% the prior day.
Multifamily credit spread: CBRE put average multifamily loan spreads at 162 basis points in Q2 2026, tightened 15 bps year over year.
Stack the fixed-rate pieces and you get roughly 6.37% as a market-average starting point, which is why the worked example above uses 6.40% for an older asset that prices slightly wider. A quote well above that on a stabilized building deserves a question.
One more signal worth reading: CBRE's Lending Momentum Index sat at 1.0 at the end of Q2 2026, down from 1.3 a year earlier, while alternative lenders such as debt funds took 38% of non-agency closings versus 34% a year earlier, and both the number and the average size of loans rose. The index eased, but lender competition in exactly this loan band grew.
Where the deals are: Houston submarkets
Houston is not one market for lending purposes, and the submarket printed on your appraisal changes both your proceeds and your rate. Cushman & Wakefield's Q2 2026 Houston multifamily MarketBeat put metro stabilized vacancy at 11.1%, but the spread between the tightest and loosest submarkets is wide enough to move a term sheet.
Table 4: Houston submarket vacancy, Q2 2026 (Cushman & Wakefield)
| Submarket | Stabilized vacancy | What tends to be financeable here |
|---|---|---|
| Submarket Sugar Land / Missouri City | Stabilized vacancy 6.4% | What tends to be financeable here Stabilized long-term fixed debt; strongest coverage in the metro |
| Submarket Pearland | Stabilized vacancy 6.5% | What tends to be financeable here Stabilized fixed debt on newer workforce product |
| Submarket Northeast Houston | Stabilized vacancy 6.6% | What tends to be financeable here Value-add bridge into agency-style takeout |
| Submarket The Woodlands | Stabilized vacancy 7.7% | What tends to be financeable here Lower leverage against higher basis per unit |
| Submarket Heights | Stabilized vacancy 7.9% | What tends to be financeable here Small infill assets; strong rents, tight coverage on basis |
| Submarket Downtown Houston | Stabilized vacancy 7.9% | What tends to be financeable here Rarely 10–30 units; institutional product dominates |
On rent levels, the same report puts metro effective rent at $1,312 per unit, with Downtown Houston at $2,124, Neartown / River Oaks at $1,956, and the Heights at $1,664. A 10–30 unit deal almost never pencils at Downtown basis; it pencils where rents sit near or below the metro average and the basis per unit is low enough that debt yield clears.
Supply is thinning, which helps existing owners. The Census Bureau's Building Permits Survey recorded 11,898 new privately-owned housing units authorized in the City of Houston during 2024, down 4,532 units from 16,430 in 2023 — the largest decline of any place in the South region that year. Cushman & Wakefield counted 11,756 units under construction metro-wide at the end of Q2 2026, down 20.8% from Q1.
Less new supply in your submarket is a genuine underwriting tailwind on a 10–30 unit building, because your competition for tenants is not a lease-up tower offering two months free. If you are financing new units rather than buying existing ones, the mechanics are different — see the Houston multifamily construction loan guide, the broader Houston market page, and the Texas market page.
Taxes and insurance: the two lines that break Houston pro formas
The fastest way to blow up a Houston small-multifamily deal is to underwrite the seller's property tax bill instead of your own. Harris County appraisal values reset after a sale, and Gulf Coast wind exposure keeps insurance quotes volatile. Together these two lines routinely consume close to half of a Houston building's operating budget.
In the worked example, taxes and insurance total $90,800 against $331,200 of effective gross income — 27.4% of revenue before a single repair. Get either line wrong by 20% and your NOI moves enough to change your loan by six figures.
The expense trend is not your friend. Analysis of Trepp benchmarking data reported by CRE Daily found multifamily insurance premiums grew at an 11.77% annual rate from 2015 to 2024, while property taxes compounded at 5.43% and total operating expenses at 4.15% annually.
How to underwrite it: get a real insurance quote on the actual building before you go hard on earnest money, and model taxes at the purchase price rather than the seller's assessed value. Lenders will do exactly this in their own underwriting, so a pro forma that does not will simply be re-cut on their spreadsheet.
What do you need before a lender will quote?
Six documents get you a real term sheet on a Houston 10–30 unit building, and missing any one of them stalls the file. Lenders quote off trailing operating history, not projections. Assemble the package before you go to market, because indicative quotes expire while you chase a rent roll from a seller's broker.
Trailing 12-month operating statement: month-by-month, not a summary. Lenders rebuild it line by line.
Current rent roll: with lease start and end dates, deposits, and any concessions. Undisclosed concessions are the single most common re-trade trigger.
Purchase and sale agreement: fully executed, with all amendments.
Personal financial statement and schedule of real estate owned: for every guarantor, even on non-recourse execution — carve-out guarantors still get underwritten.
Entity documents: operating agreement, certificate of formation, EIN letter for the borrowing entity.
Insurance loss runs and a current quote: three to five years of loss history where available.
With that package in hand, put one file in front of several lender channels at once. YieldStack is a commercial mortgage brokerage. YieldStack arranges commercial real estate financing nationwide. A 5-minute submit runs the package against 20,000+ loan programs and returns 5–8 matches, with a median first offer in under an hour. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed. Submit Your Deal →
The bottom line
A 10–30 unit Houston apartment building at $1–5M is financed on the property's income, not yours, through four competing channels that will size the same deal very differently. Debt yield — not LTV — is usually the binding constraint in this market, and it is the one number most borrowers never check.
On the $2.45M, 24-unit example above, the difference between the loosest and tightest sizing test is $375,200 of proceeds on an identical building. That spread is not something you negotiate after you have a term sheet. It is decided by which lender's screen you run the file past, which is why the single highest-leverage move in this loan band is putting one clean package in front of several channels at once and letting them compete.
