Small multifamily: the cleanest DSCR file in California

What changes when there are several units

On a single-family rental, one lease decides the file. On a fourplex, coverage is the sum of four leases against one payment — which means the rent roll, not the market, is the document that matters. A building with three long-term tenants and one vacancy reads differently from one with four leases signed last month, even when both show the same gross rent.

The second change is the expense line. Common areas, landscaping, water in some buildings, trash, and a reserve for the roof and the sewer line all sit outside the coverage ratio but inside the cash flow you actually keep. Underwriting reads the ratio; you live on the difference.

The third is unit mix. Two-bedroom units lease to households that stay; studios turn over faster and cost more to turn. A building weighted toward studios will show higher gross rent and higher vacancy expense, and a lender looking at a trailing rent roll will see both.

• Ask for the rent roll with lease dates, deposit amounts and any concessions.
• Get the trailing twelve months of operating statements if the seller has them.
• Confirm every unit is legal and permitted — a converted garage is not a unit to a lender.
• Price the insurance on the whole building, not per unit.

Two to four units versus five to ten

Two-to-four unit buildings sit in a middle category: they are residential in character but investor-owned in use. Appraisal practice typically relies on comparable sales with a rent schedule, and financing terms often look more like residential lending than like a commercial deal. That tends to help coverage because the loan is sized against value rather than against a debt-yield constraint.

Five-to-ten unit buildings move toward commercial treatment. Expect a debt coverage test on the property’s own income, a commercial appraisal, and more attention to expense ratios and reserves. In expensive California markets that shift can reduce proceeds even when the rent is strong, because the building’s net operating income — not the market rent — is what supports the loan.

The practical implication is worth stating plainly: in Los Angeles, San Diego and the Bay Area, the fourplex is often the largest building that still finances on attractive coverage. Above four units, the numbers change faster than investors expect.

The California cost lines that decide the ratio

Property taxes reassess at a change of ownership under Prop 13, so the seller’s bill is a starting point at best. In districts with Mello-Roos or community facilities bonds — common in newer Inland Empire, Sacramento and San Diego tracts — the special tax is a fixed charge that does not shrink when values fall.

Insurance is the line that has moved most in the last several years. Older buildings with original wiring, a flat roof or a hillside location can be difficult to place at any premium, and a surplus lines or FAIR Plan policy can cost materially more than a standard quote. Because that premium sits in the coverage denominator, an insurance problem becomes a loan problem.

Water and sewer are worth checking separately. In some California cities, master-metered buildings put water on the owner; in others each unit is separately metered. That single fact can move operating expenses by a meaningful amount, and it is invisible in a listing sheet.

How the file is put together

We start from the property: address, unit count, current rent roll, tax bill, insurance quote and the entity that will take title. From there we can say which programs the file clears and what would have to change if it does not — a larger down payment, a different unit mix, a different property, or a lender with a more forgiving view of the rent documentation.

Because we are a broker, we shop that package across wholesale lenders rather than fitting it to one credit box. Nothing is submitted until you have seen the structure and agreed to it, and every loan remains subject to underwriting and lender approval.
