Rent schedules, appraisals and market rent: where the DSCR number actually comes from

Two sources of rent, and they are not interchangeable

A lease is evidence of what a specific tenant agreed to pay. A market rent opinion is an appraiser’s judgment about what the property would lease for today. On a stabilized property the two are usually close, and the file is simple. On a property that has just turned over, or one that has been held by the same tenant for a decade, they can be far apart — and which one the lender uses changes the outcome.

Most programs prefer the lease where it exists and is at or near market, because it is verifiable. Where the lease is below market, some lenders will use the appraiser’s opinion and some will use the lower of the two. Where the unit is vacant, the appraiser’s opinion is the only source, and a lender will typically want to see comparable rentals supporting it.

What the appraiser is actually doing

On a two-to-four unit property the appraiser produces a rental schedule: each unit, its current rent, and a market rent estimate. The estimate comes from comparable rentals — similar unit size, condition, location and amenities, ideally leased recently. On a single-family rental the same exercise happens with comparable houses rather than units.

Condition matters more than investors expect. A unit with original kitchen and bath will be compared to other units in original condition, not to a renovated comparable. If the plan is to renovate and raise rent, the appraisal has to reflect the property as it will be, which is why renovation-then-refinance is generally sequenced rather than simultaneous.

Location adjustments are the second lever. In California, a few blocks can change the rent materially: school attendance boundaries, a freeway, a transit stop, a hillside view. The appraiser is required to make those adjustments, and a well-supported comparable set is what makes the opinion defensible to a lender.

• Current leases, including any addenda or concessions
• A rent roll with unit, tenant, rent, lease dates and deposit
• Two years of rent history if the property has been owned that long
• Comparable rental listings or leases the investor is aware of
• Utility responsibility — who pays water, trash, electricity

Two to four units versus five or more

The four-unit line changes how the rent is read. On a duplex, triplex or fourplex the appraiser values the property from comparable sales and adds a rental schedule, and the lender divides gross rent by the housing cost. On five units or more the report is commercial: the income approach deducts a vacancy allowance, management, repairs and replacement reserves from gross rent to reach net operating income, and the coverage test runs on that net figure against the debt service.

The same rent can therefore support a smaller loan on a five-unit building than the simple DSCR arithmetic on a fourplex would suggest, and in high-price California markets the difference is often the whole question. For anything at five units or more, prepare a trailing operating statement alongside the rent roll. A seller who cannot produce clean operating statements is telling you something about how the building has been run, and the appraiser will notice the same gap.

Concessions, utilities and other income

A lease with a free month or a reduced first month has two rents: the face rent and the effective rent. Appraisers and underwriters generally read the effective rent, so a building leased up with concessions shows less income than its leases suggest. If concessions were used, say so in the rent file rather than letting the underwriter find them.

Ancillary income — parking, storage, laundry, utility reimbursements billed back to tenants — is treated inconsistently. On two-to-four unit properties it is often excluded or limited; on larger buildings it can count toward net operating income when it has a documented history. Do not build it into your coverage model until the lender has said it will count, and in rent-controlled cities confirm that any utility pass-through is permitted under the local ordinance before relying on it.

Rent control changes the arithmetic, not the market

In Los Angeles, San Francisco, Oakland, Berkeley, San Jose and other California cities, rent stabilization ordinances limit how much rent can rise on covered units and restrict evictions. Statewide tenant protection law adds a limit on annual increases for many older buildings, with exemptions that include newer construction.

This produces two very different files. A building with long-tenured tenants at below-market rent may show weak coverage on in-place rent while its market rent is substantially higher. The appraiser’s opinion becomes the key document, and the lender’s willingness to use it becomes the key question. Conversely, a seller who has just raised rents to market may be showing income that the appraiser will not support once the ordinance and the comparable set are considered.

The practical preparation is to know the ordinance coverage of the specific building, the tenancy dates, and the gap between in-place and market rent. That is a conversation to have with the appraiser and the lender before the report is written, not after.

Vacancy, short-term rentals and the fallback

A vacant unit is not a dead file. Lenders generally accept the appraiser’s market rent for a vacant unit, with more scrutiny when the whole building is empty. What hurts is an unexplained vacancy: a unit that has been empty for months with no lease-up story reads as either overpriced or uninhabitable, and the underwriter will ask.

Short-term rental income is treated separately, because it is not rent in the ordinary sense. Where a lender will consider it, the file usually needs a license, documented history and a long-term market rent opinion. The fallback is the number that matters, because it is the number that survives a change in local rules.

How to prepare the rent file

Assemble the documents before the appraisal is ordered: leases, rent roll, rent history, utility responsibility, and any comparable rentals you know of. If a unit is below market, write a short note explaining why — a long tenancy, a rent-controlled unit, a below-market renewal during a soft year. If a unit is vacant, write a note about the lease-up plan and the asking rent with the comparable support.

Underwriters read files, not properties. A rent file that answers the obvious questions before they are asked is the difference between a clean approval and a week of conditions. We would rather spend an hour assembling that before the appraisal than a week explaining it after.
