The Quick Read: A lender builds the rent figure one unit at a time, adds the three units together, and divides by the full monthly payment on the property: principal, interest, taxes, insurance and any HOA dues. For each unit, most programs count the lower of the signed lease or the appraiser’s market-rent opinion. In Los Angeles, rent stabilization can hold a legal rent well below market, and that gap is what moves the ratio.
- Each unit is counted separately, then the three are summed against one payment.
- An above-market lease is generally capped at market rent; a below-market lease generally holds at the lease.
- A full appraisal with a per-unit rent schedule drives both value and coverage.
- Older Los Angeles triplexes may carry legally limited rents, so market rent can overstate what the units actually produce.
- Clearing a coverage floor is not the same as positive cash flow.

What Does “Reading Rent” Mean on a Three-Unit Building?
A DSCR loan qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. It does not use the borrower’s personal income. The lender compares the building’s rent to the building’s own monthly obligation. A triplex is still residential-style underwriting, so the unit-by-unit rent method applies rather than the net-income approach used on larger apartment buildings.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage.
Across the wholesale network Lendmire works with, the pattern is consistent. Rent has to be supported by evidence, and evidence comes from two places: what the tenants actually pay under signed leases, and what an appraiser says the units would rent for on the open market. The lender does not take the owner’s pro forma on faith.
Key Terms Defined
DSCR (debt service coverage ratio): Monthly rent divided by the monthly payment on the property.
PITIA: Principal, interest, taxes, insurance and any HOA dues, which together form the divisor in the ratio.
Market rent: The appraiser’s opinion of what a unit would rent for today, based on comparable rentals.
Rent roll: A schedule listing each unit, its tenant, its lease terms and its rent.
Rent stabilization: A local law that limits how much and how often a landlord can raise rent on covered units.
Form 1025: The appraisal report used for two- to four-unit properties, which reports rent for each unit.
How Does Underwriting Treat Rent, Step by Step?
The sequence is the same on most programs, and each step matters for a triplex.
Step 1: Order a full appraisal with the rent schedule. For two- to four-unit properties, the form is the Small Residential Income Property Appraisal Report, known as Form 1025. The one-unit rent schedule, Form 1007, is for single-family investment homes, so it is the wrong tool for a triplex. DSCR loans are not agency loans. Lenders simply borrow these standard forms. The appraisal does two jobs: value drives the loan-to-value test, and market rent drives coverage.
Step 2: Gather documents for every unit. That means a signed lease or rent roll and evidence that rent is actually being paid. Month-to-month or expired leases often fall back to market rent. A lease signed very recently typically needs proof that the deposit and first month were paid.
| Unit situation | Rent usually counted | What the file needs |
|---|---|---|
| Lease at market | Lease (equals market) | Lease, payment proof |
| Lease above market | Market rent | Lease, appraisal rent schedule |
| Lease below market | The lease | Lease, payment proof |
| Month-to-month or expired | Often market rent | Rent roll, payment history |
| Vacant | Market rent, if the program allows | Appraisal rent schedule |
Programs differ on the edges, especially vacant units, so treat the table as the usual pattern rather than a rule every lender follows.
Step 3: Sum the three units. The total is gross monthly rent. Most programs do not apply a separate vacancy haircut to it.
Step 4: Divide by PITIA. On an interest-only structure, the divisor is the interest-only payment plus taxes, insurance and dues, because there is no principal in it.
Step 5: Compare to the program floor. 1.00 is where select programs start. Stronger coverage generally opens better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Repairs, vacancy, management, utilities and capex sit outside the formula entirely.
The appraiser documents rent, but the lender decides how income counts. As the McKissock appraisal education blog explains, the form considers both rental income and market value of the comparables, and it measures monthly rent rather than nightly rates. What decides the outcome is the appraiser’s per-unit conclusion and the lease terms. Your own spreadsheet does not.
Why Does Los Angeles Change the Reading?
Los Angeles changes the reading because many triplexes are rent-stabilized, and a stabilized unit’s legal rent can sit well below what the appraiser thinks the unit could fetch. Certain replacement units built after July 15, 2007 can also be covered, and the city’s Just Cause Ordinance covers most residential property that is not under the stabilization ordinance.
That means a large share of older triplexes can have legally limited rents. The appraisal form even asks the question directly: the Form 1025 itself includes a field on whether the property is subject to rent control.
Here is the mechanical consequence. The appraiser’s market-rent opinion is an opinion. Where a legally limited rent applies to a sitting tenant, that opinion generally cannot override it, which is why lenders pay attention to the stabilization status on the appraisal.
How Fast Can a Stabilized Rent Catch Up?
Slowly, and by formula. The city’s renter protections page states the annual increase is 3% for July 1, 2026 through June 30, 2027. It also says the formula changed on February 2, 2026 to 90% of CPI, with a 1% minimum and a 4% maximum. Utility add-ons are no longer allowed, and increases are allowed once every 12 months.
So a long-tenured tenant paying a legacy rent will not climb to market in a single renewal. The lower-of rule then holds the numerator at the lease figure for years.
What About Units Outside the City Ordinance?
Units not covered by the local ordinance may fall under the state’s tenant protection law, which limits increases to 5% plus regional inflation, with a 10% ceiling, as the Contra Costa Housing Authority describes. That page also notes that units already under a stricter local limit are excluded. The regional inflation piece varies by area, so an investor should not borrow another region’s figure for a Los Angeles building. Confirm the applicable cap locally.
One more point. Exemptions that help single-family homes and condominiums usually do not rescue a triplex, since a triplex is neither.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
A Worked Example: One Triplex, Three Lease Situations
Run the numbers on a modeled triplex with three different unit situations. These are illustrative assumptions, not market data.
- Unit A: a long-tenured tenant on a legacy stabilized lease, well below the appraiser’s market opinion. The lease counts.
- Unit B: a month-to-month tenant. The appraiser’s market rent likely counts, supported by payment history.
- Unit C: vacant and turnover-ready. Market rent from the appraisal counts, if the program allows it and the appraiser supports it.
Now compare two outcomes against the same payment. In the first, the appraiser’s rent opinions come in strong, and the total clears the floor with room to spare, say around 1.2x. In the second, the comparables are mixed, the market opinions on Units B and C come in lower, and coverage drops toward 1.0x. The building, the loan and the tenants are identical. Only the appraiser’s rent conclusion moved.
If coverage lands below 1.00, the structures worth discussing include a sub-1.00 path through select lenders in the network, with leverage and terms adjusted, or an interest-only structure from select lenders, which lowers the divisor. Qualification stays subject to lender guidelines, credit approval and property review.
Where Does the General Rule Break?
Several edge cases change the outcome.
- Above-market leases. An above-market lease helps the owner’s cash flow, not the ratio. The excess is capped away.
- Owner-occupied unit. If the owner lives in one unit, the file does not fit a non-owner-occupied DSCR program. Confirm against program guidelines.
- Family-member leases. These get extra scrutiny, and market rent usually governs.
- Short-term rentals. Form 1025 measures monthly rent. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. STR programs carry their own leverage, hosting-history and coverage requirements.
- Unit count mismatches. A garage conversion or an unpermitted “fourth unit” can create a gap between what is rented and what the city recognizes as a legal triplex. Rent from a unit the property record does not support is a problem for the file, not a bonus.
- Ancillary income. Parking, pet fees and reimbursements are generally not part of the core rent reading.
- Ineligible property types. Manufactured homes, log homes and barndominiums are not offered in the network’s DSCR programs.
What Does the Investor Decision Look Like?
For an investor with a stabilized triplex, the decision usually turns on four things.
Leverage versus coverage. Most purchase files land between 75% and 80% LTV on an investment property. A larger down payment lowers the payment and can lift the ratio, but it never erases credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Credit and reserves. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Reserves commonly run about six months of PITIA, stepping up to about nine months on loans above $1,500,000, though they vary by lender, leverage and transaction.
Timing the appraisal. Where leases can legally be renewed at higher rents before the appraisal, the numerator may rise, within the city’s cap. Do not push a renewal that the ordinance does not allow.
Check the building’s status first. Confirm the certificate of occupancy date and stabilization status before underwriting. Two triplexes on the same block can have very different rent paths.
Then comes the expense blind spot. Clearing 1.00 is not positive cash flow. Older triplexes carry three sets of repair, vacancy and utility exposure that the ratio never sees. A passing number still deserves a separate operating budget.
If an investor is pulling equity from a stabilized building, Lendmire’s piece Los Angeles Rental Cash-Out Refinance When Rent Control Caps Income covers that angle. Cash-out refinances top out around 75% LTV across most of the network, with about six months of seasoning commonly expected.
Pre-Submission Checklist for a Triplex File
- Signed leases for each occupied unit
- A current rent roll
- Proof that rent is actually being paid
- Stabilization status and certificate of occupancy date
- Confirmation that the unit count matches city records
- A plan for any vacant unit’s market-rent support
- Insurance quote and tax figures, so PITIA is firm
Tax treatment varies; consult a qualified professional.
Frequently Asked Questions
Does an above-market lease help my DSCR?
Not beyond market. Most programs count the lower of the lease or the appraiser’s market-rent opinion, so the excess does not lift the ratio. It still helps your actual cash flow.
Can one vacant unit sink the file?
Usually not on its own. Many programs count market rent for a vacant unit when the appraisal supports it, though some add lease-up or seasoning conditions. Programs differ, so ask early.
Does rent stabilization lower my counted rent?
It can, yes. If a legally limited rent applies to a sitting tenant, that limit generally governs over the appraiser’s higher market opinion. The gap shows up as a lower ratio than the building’s price would suggest.
Which appraisal form is used on a triplex?
Form 1025, the small residential income property report for two- to four-unit properties. Form 1007 is for one-unit investment homes.
Can I count an ADU or extra unit?
Only if it is legal and recognized in property records. Rent from an unpermitted unit generally is not credited, and a mismatch in unit count can complicate the file.
