BY SIZE
Multifamily Financing by Building Size
The optimal loan product changes dramatically based on unit count. A 5-unit walk-up and a 150-unit garden complex use completely different financing paths.
Small Multifamily (5–20 Units)
Walk-ups, small apartment buildingsThe entry point for most apartment investors. DSCR loans are common here — no personal income docs, qualification based on rent roll. Portfolio banks and credit unions also compete. Down payment: 20–25% for a DSCR loan. Many investors start here and 1031 exchange up.
Mid-Size Apartment (20–50 Units)
Garden-style, low-rise complexesEnough units for meaningful economies of scale. On-site management becomes justified. Bank and CMBS options open up alongside DSCR. Agency small-loan programs (Fannie Mae Small Mortgage Loans, Freddie Mac Small Balance Loans) are open to buildings of five or more units; Freddie Mac’s targets loans of $1 million to $7.5 million.
Large Apartment (50+ Units)
Institutional-grade, agency-eligibleFull agency financing (Fannie Mae DUS, Freddie Mac Optigo): 5–30 year terms, up to 30-year amortization, and non-recourse execution with standard carve-outs for bad acts such as fraud and bankruptcy. HUD 223(f) loans can run up to 35 years. Life company and CMBS also compete. Professional management required.
FINANCING OPTIONS
Loan Options for Multifamily Properties
Apartment buildings have a financing source most other property types lack: agency lending from Fannie Mae and Freddie Mac, plus FHA insurance under HUD Section 223(f).
DSCR Loan
No personal income docsCommon for 5–20 unit buildings. No tax returns. Qualification based on rent roll. Close in 21–35 days. Scale your portfolio without affecting personal DTI.
Agency (Fannie/Freddie)
Non-recourse option, up to 30-year amortizationFannie Mae and Freddie Mac loans made through approved lenders: non-recourse execution with standard carve-outs for bad acts, fixed or variable rates, up to 30-year amortization. Only for residential rental property (not office, retail, or industrial). For stabilized properties — Fannie Mae DUS typically looks for 90% occupancy for the 90 days before funding.
Conventional Bank
Local banks, relationship pricingFull documentation. Community banks may offer relationship pricing and flexibility on unit count. Good for borrowers with existing banking relationships.
CMBS / Bridge
Large deals, value-add, repositioningCMBS for large stabilized complexes. Bridge for value-add deals: acquire, renovate units, raise rents, then refinance into agency or permanent. Non-recourse available.

KEY METRICS
What Lenders Evaluate for Apartment Loans
These are the core metrics apartment lenders evaluate.
LOAN SIZING
Example: How Much Can You Borrow on an Apartment Building?
Apartment lenders size the loan by the property’s income, not just its price. The loan is the lower of two limits: a loan-to-value cap and the largest loan whose payment the net operating income covers at the lender’s minimum DSCR. At rates like the example below, the DSCR limit can bind first — so buyers may need to put down more than the LTV cap alone suggests.
Example: a 20-unit building priced at $3,000,000 with $180,000 of annual NOI (a 6% cap rate). Assumptions for illustration only: 6.5% interest rate, 30-year amortization, lender limits of 75% LTV and 1.25x minimum DSCR.
To borrow closer to 75% LTV on this building, the NOI would need to be about $213,000, or the rate lower. Run your own numbers with the max loan calculator (all three limits at once) or the DSCR calculator, and check your per-unit price with the price per unit calculator. The loan checklist lists the documents apartment lenders ask for, and the commercial real estate loan application starts a comparison with no hard credit pull.

FAQ
Frequently Asked Questions
How do apartment complex loans work?
An apartment complex loan is a commercial mortgage secured by the building. The lender sizes it from the property’s rent roll and net operating income: the loan is the lower of a loan-to-value cap and the amount the NOI can repay at a minimum DSCR (often 1.20–1.25x for bank and agency loans). Bank loans usually have a 5–10 yr term with 20–30 yr amortization and a balloon at maturity; agency and HUD-insured loans can run longer. Buildings with five or more units are financed this way — one to four units use residential mortgages.
Who lends on apartment buildings?
Six main groups: local and regional banks and credit unions; Fannie Mae DUS lenders and Freddie Mac Optigo lenders (agency loans, five or more units); FHA-insured lenders under HUD Section 223(f) for buying or refinancing existing apartment properties; life insurance companies for low-leverage loans on stabilized buildings; CMBS lenders for larger loans; and DSCR and bridge lenders for smaller or value-add buildings. BestLoanUSA is not a lender — we compare offers from 30+ lenders across these groups, with no hard credit pull to start.
How much down payment do you need for an apartment building?
The LTV cap sets the minimum — 25–35% for a typical bank loan and 20–25% for a DSCR loan — but the property’s income often requires more. In the example above, a $3,000,000 building with $180,000 NOI qualifies for $1,898,000 at a 6.5% example rate and 1.25x DSCR, so the buyer needs about 37% down, not 25%. Higher NOI or a lower rate closes that gap.
What documents do lenders need for a commercial loan on an apartment building?
Expect a current rent roll, the trailing 12-month (T-12) operating statement, the purchase contract or current loan payoff statement, a schedule of real estate you own, a personal financial statement, and entity documents. Bank loans also ask for recent personal (and, where applicable, business) tax returns; DSCR loans qualify on the property’s income and skip personal income documents. The lender orders the appraisal and third-party reports. The BestLoanUSA loan checklist builds the list for your deal.
At what unit count does a property become "commercial" multifamily?
Properties with 5 or more residential units are classified as commercial multifamily and require commercial financing. 1–4 unit properties are residential and can use conventional residential mortgages (Fannie Mae residential, FHA). The financing options, rates, and underwriting process are fundamentally different above and below the 5-unit threshold.
What is agency lending and why is it special for apartments?
Agency lending refers to loans originated through Fannie Mae and Freddie Mac multifamily programs. Typical terms: 6.25–7.25%, 5–30 year terms with up to 30-year amortization, up to 80% LTV, and non-recourse execution — you’re not personally liable except for standard carve-outs such as fraud and bankruptcy. The programs finance residential rental property, not office, retail, or industrial.
Can I buy a 5-unit building with no income verification?
Yes. DSCR loans qualify you based on the property’s rent roll, not your personal income. If the building’s NOI covers at least 1.0–1.25x of the annual debt service, you qualify without providing tax returns, W-2s, or pay stubs. It is a common path for investors building a portfolio of small apartment buildings.
What is a value-add multifamily deal?
Value-add means acquiring a property below market value, renovating units (new kitchens, bathrooms, flooring, appliances), raising rents to market rates, and refinancing at the higher appraised value. Bridge loans fund the acquisition and renovation. Once stabilized (85–90%+ occupancy) with market rents, you can refinance into permanent or agency financing, typically at a lower rate than the bridge loan.
How do lenders analyze a rent roll?
Lenders examine current rents vs market comparables, lease expiration dates, tenant payment history, vacancy trends, and unit mix. They calculate effective gross income (total rent minus vacancy and concessions), subtract operating expenses, and arrive at NOI. The rent roll is the foundation of multifamily underwriting — a clean, well-documented rent roll helps underwriting move faster.
Can I use a 1031 exchange to buy an apartment building?
Yes. Many investors use a 1031 exchange to move into multifamily. Sell a smaller investment property, defer capital gains taxes, and reinvest into a larger apartment building. The exchange must follow IRS rules: identify replacement property within 45 days and close within 180 days. Many investors 1031 from single-family rentals or small multifamily into larger apartments.

- CRE Refinancing A commercial real estate refinance replaces your existing mortgage with a new loan — to lower the rate, replace a maturing balloon, move from floating to fixed, or take cash out. To refinance, check your current loan’s maturity and prepayment penalty, get the property appraised, show that its net operating income covers the new payment at the lender’s minimum DSCR, compare term sheets and close — the new lender pays off the old loan, usually in 30–60 days.
