The four-to-five unit cliff
When a rental property has 5 or more legal units, it usually stops being a residential DSCR loan. A fourplex can fit 1 to 4 Unit DSCR with leases and market rent on each unit. At five units, the same building is an apartment property in most lender boxes.
That shift is not cosmetic. Documentation, minimum loan size, how expenses are reviewed, and who will actually quote the deal all change. Investors stepping from four units into a six or eight unit building often discover their residential lender simply does not have a product slot.
- ✓Residential DSCR: 1 to 4 legal units
- ✓Small multifamily DSCR: 5 to 10 legal units
- ✓Apartment DSCR: 11 or more legal units
5 to 10 units: small multifamily DSCR
Stabilized 5 to 10 unit apartment buildings typically fit 5 to 10 Unit DSCR. Underwriting still uses property income, but the rent roll matters more than a single lease. Lenders look at occupancy, delinquency, concessions, and whether trailing income supports the payment.
- ✓Loan sizes: $500,000 to $15,000,000
- ✓Up to 75% LTV on refinance and purchase
- ✓Terms: 25 to 30 years fixed with interest-only options on select deals
- ✓Minimum DSCR: often 0.90 on smaller balances and 1.0 above $1 million
This lane exists because 5 to 10 units is too big for residential DSCR and often too small for a full agency apartment process. Garden-style buildings in the 6 to 10 unit range are a common fit.
