Multifamily Hard Money Loans: Financing 2-4 Unit Investment Properties

Hard money loans for 2-4 unit multifamily properties — duplexes, triplexes, and fourplexes — work similarly to single-family hard money loans, with some important differences. The property is still underwritten primarily on its value and the deal structure, not the borrower's personal income. Lenders evaluate the as-is value, the after-repair value (on fix-and-flip deals), and the exit plan in the same way they would for a single-family home.

The key differences are that rental income from occupied units can be factored into the loan analysis, lenders may apply slightly different LTV ratios depending on occupancy and condition, and the underwriting for a BRRRR-to-DSCR exit is often more favorable on a multifamily property because the diversified rental income produces a more predictable DSCR calculation than a single-unit property.

Two-to-four unit properties offer a unique advantage in hard money investing: the ability to use rental income from occupied units to offset carrying costs during a rehab or stabilization period. When you purchase a duplex where one unit is occupied, the rent from that unit can cover a portion of your monthly interest payment while you renovate the vacant unit. This reduces your actual out-of-pocket holding costs compared to a vacant single-family home.

Multifamily properties also tend to produce stronger DSCR ratios on the refinance end, which makes the BRRRR strategy more reliable. Two rental units at $1,200 per month each produce $2,400 in gross monthly income — a figure that typically supports strong DSCR qualification at 75-80% LTV.

LTV limits on 2-4 unit hard money loans are generally in the same range as single-family properties: up to 85-90% of the purchase price for fix-and-flip deals, capped at 70-75% of ARV. Some lenders apply slightly more conservative ARV limits on multifamily properties because the appraisal process is more complex and comparable sales can be harder to establish in thin markets.

For DSCR refinances on stabilized multifamily properties, lenders typically allow up to 80-85% LTV on purchases and 70-75% LTV on cash-out refinances. The key underwriting metric on the DSCR side is whether the combined rent roll covers the PITIA at the loan terms — a hurdle that small multifamily properties usually clear more easily than single-family homes given their diversified income.

The most common structure for 2-4 unit hard money deals is a fix-and-flip or BRRRR acquisition, where the investor purchases a distressed property, renovates it, then either sells (flip) or refinances into long-term DSCR debt (hold). On a duplex purchase where one unit is vacant and one is occupied, the active rent partially offsets carrying costs during renovation.

Bridge loans are also commonly used on small multifamily properties for stabilization scenarios — buying a partially occupied property, stabilizing it to full occupancy, and then refinancing into DSCR. This structure works when the as-stabilized rent roll clearly supports the DSCR refinance, which should be modeled before the bridge is originated.
