What financing is available for 2-4 unit small multifamily?

Small multifamily (2-4 units) qualifies for residential conventional, FHA, VA, and USDA financing — rates typically 100-200 bps lower than commercial multifamily debt + as low as 3.5% down for FHA owner-occupant, 0% down for VA owner-occupant. The owner-occupancy requirement (live in one unit for 12+ months for FHA/VA) is the entry path for "house-hacking" — using FHA owner-occupant financing to acquire a duplex/triplex/fourplex, occupy one unit, rent others. After 12 months, the owner can refinance into investment property loan or repeat the cycle. 5+ unit properties require commercial multifamily financing (DSCR-based, 25-30% down).

Who owns small multifamily real estate?

Small multifamily (2-4 unit) ownership is dominated by private investors — house-hackers, BRRRR-strategy investors, small landlords, 1031 exchange buyers. The market is highly fragmented (~$200B+ private market) with no institutional REIT pure-play. Some institutional aggregation has emerged: Roofstock (online marketplace + management), Mynd Management (tech-enabled property management for small portfolios), AcreTrader (small property syndication). Public multifamily REITs (EQR, CPT, MAA, ESS, AVB) hold 5+ unit "garden-style" + mid-rise buildings — different asset class.

What is house-hacking?

House-hacking is the strategy of using owner-occupant financing (FHA, VA, USDA) to acquire a 2-4 unit small multifamily property, living in one unit while renting others. The economic benefit: owner-occupant down payment (3.5% FHA, 0% VA) + lower interest rate (~100-200 bps below investment) + rental income from other units often covering most or all of the mortgage payment. After 12-month owner-occupancy requirement, the owner can buy another property using the same strategy — building a portfolio rapidly. House-hacking is a primary entry path for first-time real estate investors; risk is concentration (single asset, single market) + landlord-tenant overlap (living next door to tenants).

Small Multifamily KPIs.

Small Multifamily is 2-4 unit residential rental property — duplex, triplex, fourplex — distinct from large multifamily (5+ units, considered commercial real estate by lenders). The defining characteristic is financing eligibility: 2-4 unit properties qualify for residential conventional, FHA, VA, and USDA financing (1-4 unit owner-occupied loans), with rates typically 100-200 bps lower than commercial multifamily debt + as low as 3.5% down (FHA owner-occupied). The category is dominated by private investors — house-hackers, BRRRR strategy operators, small landlords, and 1031 exchange buyers — rather than institutional REITs. Performance is measured per-unit (EGI, NOI, occupancy) often aggregated across small portfolios. House-hacking (owner-occupies one unit, rents others) is a primary entry path for first-time investors. There is no public REIT pure-play — small multifamily ownership is highly fragmented (~$200B+ private market).

NOI: Total revenue minus operating expenses (excludes financing and capital costs). The primary measure of property-level profitability.
Cap Rate: Net Operating Income divided by current property value. Expresses unleveraged annual yield as a percentage.
DSCR: Net Operating Income divided by total annual debt service. Lender-required cushion measure; below 1.0 means NOI cannot cover debt.
LTV: Loan amount divided by property value. Lower LTV = lower lender risk.
OER: Operating expenses divided by gross revenue. Lower is better, but varies by property type (hotels run higher than triple-net retail).
GRM: Property value divided by gross annual rental income. Quick valuation shortcut; less precise than cap rate.
IRR: Annualized return on investment accounting for time value of money across the full hold period.
CoC: Pre-tax annual cash flow divided by total cash invested. Measures the cash yield, not total return.
DCF: Valuation method that projects future cash flows and discounts them to present value at a chosen rate.
TTM: A rolling sum of the most recent 12 months. Smooths seasonality for KPI comparisons.
EGI: Gross potential rent minus vacancy and credit losses, plus other income (parking, laundry, fees).
LTL: Difference between market rent and current contract rent across the rent roll. Measures lease-up opportunity on turnover.
Renewal: Percentage of expiring leases that renew. Higher renewal rates indicate retention; turnover costs avoided.
Concessions: Concessions (free months, discounts) divided by gross rent. Measures pricing pressure.
RUBS: Method of allocating master-metered utility costs to residents based on unit area or occupant count.
