Financing a 5+ Unit Multifamily Property: Agency, Bank and Bridge Options

By MercFinancial · Published 2026-08-28 · Updated 2026-09-07

Multifamily financing for 5+ units is commercial underwriting: the loan is sized on net operating income and debt coverage, not comparable sales. Here is how agency, bank and bridge loans differ and what a lender package needs.

Multifamily financing changes at five units. A property with one to four units is financed as residential, on comparable sales and either your personal income or a DSCR program; at five units and above it is a commercial asset, and the loan is sized on the property's net operating income and the coverage that income provides over the debt service. Three lender families serve that market: agency small-balance programs through approved lenders, banks and credit unions, and bridge lenders for properties that are not yet stabilized. Which one fits depends on occupancy, condition, your experience and how long you plan to hold.

This article explains why five units moves a property into commercial underwriting, how agency, bank and bridge loans differ in general terms, how lenders rebuild your net operating income and set coverage and reserves, and what a complete lender package contains. The nuance matters because the seller's pro forma and the lender's underwritten income are rarely the same number, and the loan is sized to the second one.

"The seller's broker handed me a one-page pro forma with a rent increase already baked in. The lender rebuilt the numbers from the trailing twelve months and the actual rent roll, and the loan it offered was sized to that, not to the brochure."

Why Five Units Changes the Loan

Residential lenders value a fourplex the way they value a house, from comparable sales, and qualify the borrower on personal income or a simple rent-to-payment ratio. At five units the appraisal shifts to the income approach: the appraiser estimates net operating income and applies a capitalization rate drawn from sales of similar income properties, so value follows income directly. The lender then sizes the loan to the lower of two limits, a maximum loan-to-value and a minimum debt service coverage, which is why two buildings at the same price can support very different loans. Those limits are explained in LTV, LTC and ARV explained.

Commercial multifamily loans also bring a borrowing entity, a review of the sponsor's net worth, liquidity and track record, third-party reports beyond the appraisal, and terms that often end in a balloon or a rate reset. Recourse varies: banks usually require a full personal guarantee, while agency loans are typically non-recourse with carve-outs for fraud, misuse of funds and similar acts.

Multifamily Financing for 5+ Units: The Three Lender Families

The table captures the core trade: the cheapest, longest money goes to properties that are already performing, and the fastest, most flexible money goes to properties that are not.

Agency Small-Balance Loans

The two housing agencies each run a small-balance multifamily program delivered through approved lenders rather than directly. In general terms, these loans want a stabilized property with occupancy above the program's threshold for a seasoning period, a sponsor whose net worth and liquidity meet minimums set relative to the loan amount, and some ownership experience. They offer long fixed-rate periods, amortization, non-recourse structure and assumability, and they impose replacement-reserve escrows and prepayment terms that make an early sale expensive. Program parameters change, so verify the current ones with the lender.

The trade-off is process. Agency loans wait on an appraisal, a property condition assessment and an environmental report, plus the lender's and the agency's reviews, so they take longer than a bank loan. They fit long-term holders of performing buildings in markets the programs serve.

Bank and Credit Union Loans

Banks and credit unions lend on multifamily as portfolio lenders, keeping the loan on their own books, which gives them flexibility the agencies lack. They will look at a building that is slightly under-occupied or needs cosmetic work, at smaller loan amounts, and at sponsors with less history, and they can close in weeks. In exchange they require a full personal guarantee, price shorter fixed periods with a balloon or reset, often ask for a deposit relationship, and underwrite the sponsor's global cash flow alongside the property's. The wider commercial requirements are covered in commercial real estate loan requirements.

Bridge-to-Stabilization for Value-Add Properties

A property that is half empty, poorly managed or in need of renovation will not qualify for agency or most bank financing until it is stabilized, and a bridge loan fills that gap. The lender funds the purchase and, through a holdback drawn as work completes, the renovation budget; payments are interest-only, often from a reserve funded at closing; and the term is short with extension options at a price. The lender underwrites the business plan: the capital budget with contractor bids, the rent comparables behind the projected rents, the lease-up timeline and the sponsor's ability to execute.

The exit is the whole point. Once the building is stabilized and seasoned, it refinances into an agency or bank loan sized on the new net operating income. The exit options and their failure modes are covered in bridge loan exit strategies; if the plan is to build rather than renovate, ground-up construction loans for investors covers that separate track.

DSCR, Reserves and How Lenders Rebuild Your NOI

Every multifamily lender starts from the trailing twelve months of operating statements and the current rent roll, then rebuilds the income statement to its own standard. Vacancy is set at the lender's minimum even if the building is full. Management is charged as a fee even if you manage it yourself. Replacement reserves are deducted per unit, and insurance is underwritten at a current quote rather than the seller's old policy. In Texas, property taxes are underwritten at the value the appraisal district will assign after the sale, because a purchase resets the basis and the tax bill can rise sharply in the first full year.

The result is underwritten net operating income, and the debt service coverage ratio is that figure divided by the annual loan payment. A ratio of 1.0 is break-even; every lender requires a cushion above it, and the size of the cushion varies by lender family and property. Reserves come in two layers: escrows the lender holds for taxes, insurance and replacements, and post-closing liquidity you must show in your own accounts.

What a Lender Package Needs

A complete package shortens every timeline above. From the seller: the trailing twelve months of operating statements, the current rent roll with lease start and end dates, two or three years of historical operating statements, current leases, utility bills, the property tax statement and the existing insurance policy. From you: the purchase contract, a personal financial statement, a schedule of real estate owned, a resume or track record, the borrowing entity's formation documents, a capital budget with bids if work is planned, and an insurance quote. The lender orders the appraisal, environmental report and property condition assessment; what the appraiser looks for is in the investment property appraisal checklist.

Frequently Asked Questions

Is a 5-unit building considered commercial?

Yes. Residential lending stops at four units. From five units up, the property is a commercial asset, valued by the income approach and financed with commercial multifamily loans sized on net operating income and debt service coverage. The borrower is usually an entity, the sponsor's net worth and liquidity are reviewed, and third-party reports beyond the appraisal are typical.

How much do you need down on a 5+ unit multifamily property?

It depends on the building's underwritten income rather than a fixed rule. The lender sizes the loan to the lower of its maximum loan-to-value and the loan the net operating income can cover at its required ratio, and the equity is whatever remains of the price and closing costs. A building with thin income needs more equity, and value-add projects need more still.

Can I get an agency loan on a small apartment building?

Often, if the property is stabilized and in acceptable condition, the market is one the program serves, and you meet the sponsor net worth, liquidity and experience requirements. Agency small-balance loans are delivered through approved lenders, take longer to close than bank loans because of the third-party reports and reviews, and carry prepayment terms that suit long-term holders. Verify current program parameters with the lender.

What debt service coverage ratio do lenders require on multifamily?

Every lender requires underwritten net operating income to exceed the annual debt service by a cushion, and the size of that cushion varies by lender family, property quality and market. What matters more than the ratio itself is that lenders compute it on their own rebuilt income, with minimum vacancy, a management fee, replacement reserves and reassessed property taxes, not on the seller's pro forma.

How long does it take to close a multifamily loan?

Bank and credit union loans commonly close in a matter of weeks once the package is complete. Agency small-balance loans take longer because they wait on an appraisal, a property condition assessment, an environmental report and two layers of review. Bridge loans can close fastest. In every case the biggest variable is whether the seller's operating statements and rent roll arrive complete and reconcile to each other.
