The Quick Read: A DSCR lender lends the smaller of two ceilings on a $2M triplex: the leverage cap applied to value, or the largest loan the building’s rent can support at the coverage floor. In San Francisco, the rent ceiling often binds first, because high prices, a reassessed tax bill, and rent-controlled leases all weigh on the ratio.
- Purchase leverage typically runs 75%–80% LTV on an investment property, subject to lender guidelines.
- Cash-out on a rental tops out around 75% LTV across most of the network.
- Coverage of 1.00 is where select programs start. Stronger ratios open better terms and leverage.
- Reserves run about 6 months of PITIA, stepping up to about 9 months above $1,500,000.
- A $2M loan sits inside the standard range (up to $3,000,000), but above $1,500,000 the reserve step-up applies.
Lendmire arranges DSCR investor loans through select lenders in its wholesale network. It does not underwrite or approve them. Those lenders do.

Key Terms Defined
DSCR: Eligible monthly rent divided by the monthly housing payment on the property.
PITIA: Principal, interest, taxes, insurance, and any association dues. Interest-only files use ITIA instead.
LTV: The loan amount as a percentage of the lower of price or appraised value on a purchase.
Coverage ceiling: The largest payment the rent can support at the coverage floor.
Market rent: The rent the appraiser says a unit would command, as shown on the appraisal’s rent schedule.
What Are the Two Ceilings on This Loan?
The loan is the smaller of the value ceiling and the coverage ceiling. Think of two gates. The file has to clear both.
The value ceiling is simple. Take the leverage cap for the transaction and apply it to the price or appraised value, whichever is lower on a purchase. On a $2M purchase at 75%–80% LTV, the value ceiling is a percentage of $2M. The calculator on this site can turn that into dollars as an illustrative estimate. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
The coverage ceiling takes more work. Divide the rent used for review by the coverage floor. That gives the largest PITIA the building can carry. Then work backward to the loan that produces that payment. Taxes and insurance don’t shrink when rent does, so a modest rent shortfall can cut the supportable loan by more than the percentage gap.
Here’s the catch. A bigger down payment lowers the payment and can lift the ratio. It never erases credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. Lendmire’s complete DSCR loans guide walks through the full qualification picture.
How Does Underwriting Treat a Triplex, Step by Step?
Underwriting treats a triplex as a small residential income property. It stays in DSCR territory at two to four units. At five or more units, the deal moves to commercial multifamily underwriting.
1. Transaction type. Purchase, rate-and-term, or cash-out. Cash-out sits at the low end of the leverage range, around 75% LTV on a standard rental. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
2. Appraisal. For two to four units, the appraiser uses the small residential income property report, commonly known as Form 1025. DSCR loans are not agency loans, so the form name is borrowed. The appraisal still does two jobs: it sets value for the LTV test and market rent per unit for the coverage test.
3. Rent per unit. Across most programs, each unit is tested on its own. The usual convention is the lower of the signed lease and the appraiser’s market rent. An above-market unit does not offset a below-market one.
4. Vacant units. Appraiser’s market rent usually stands in. A vacant unit does not make the building owner-occupied. An owner living in one unit takes the loan out of DSCR territory.
5. Documents. Expect leases, a unit-by-unit rent roll, and proof of rent payment. Entity documents are added if the property sits in an LLC, subject to lender program eligibility.
6. Pool the units over one PITIA. Three units of rent sit over one tax bill and one insurance policy. That’s why small multifamily often covers better than a single-family rental.
7. Run the test at the requested loan. If coverage fails, the options are a lower loan, more down, or an interest-only structure that tests on ITIA. Interest-only periods are available through select lenders in the network.
Why Does San Francisco Squeeze the Coverage Ceiling?
Three local forces push the payment up or hold the rent down. All three show up in the numbers before the lender looks at anything else.
Reassessment. California reassesses on a change of ownership. Per the California Board of Equalization, the base rate is 1% plus voter-approved debt, and a property is reassessed to market value when it sells. The buyer of a $2M triplex pays tax on the new basis, not the seller’s long-held one. If a file is sized off the seller’s tax bill, the PITIA is understated and the ratio comes back higher than it should be. Use the new-basis number.
Rent control. San Francisco’s rent ordinance caps how much rent can rise each year on covered units. Long-tenured tenants climb slowly. Their leases can sit well below what the same unit would command vacant.
Appraisal form questions. Form 1025 itself asks whether the property is subject to rent control. The appraiser has to address it.
Where Does the General Rule Break?
Five edge cases change the answer on a San Francisco triplex.
Below-market leases. Under the lower-of convention, a long-tenured tenant’s lease caps that unit’s rent. The vacant unit next door counts at market rent. The blended number lands under the “market” sum. Whether the appraiser’s rent for a controlled unit reflects the legal cap is a lender and appraiser question. Confirm it before the file is sized.
Vacancy decontrol. California law generally lets landlords reset rent after a qualifying vacancy, per the legislative analysis of SB 466. It also bars local rent control on single-family homes and condos. Exceptions exist for certain vacancies. Underwriting generally credits current rent evidence, not a reset that hasn’t happened.
Leases to relatives. These draw scrutiny. Market rent usually governs.
Fully vacant buildings. Often workable on appraisal market rent. Some lenders trim leverage, discount the rent, or want a lease in place on a refinance.
Owner occupancy. If the borrower plans to live in a unit, this isn’t a DSCR file. DSCR loans are designed for non-owner-occupied investment properties. Because they’re business-purpose investor loans, they’re reviewed differently from a standard owner-occupied mortgage.
Property type matters too. DSCR programs in the network do not cover manufactured homes, log homes, or barndominiums. A San Francisco triplex is a standard asset. Just keep the eligibility list in mind for any other building in the search.
What Does the Coverage Ratio Mean in Practice?
A ratio near 1.00 means rent roughly equals PITIA. It does not mean positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation. On a building this size, those costs are not small.
Here’s a clean way to think about a $2M scenario. Say the lender applies 75% LTV on a purchase. The rent on three units has to support the payment on that loan at the coverage floor. If it doesn’t, the file doesn’t die. It re-sizes. Every figure here varies by lender and program, since guidelines, property type, leverage, and credit profile all apply.
Run the levers in this order:
| Lever | What it does | Trade-off |
|---|---|---|
| More down payment | Lowers PITIA, lifts ratio | More cash in the deal |
| Interest-only structure | Tests on ITIA, raises ratio | Available through select lenders only |
| Documented market-rent renewal | Lifts the rent used | Not credited before it takes effect |
| Sub-1.00 path | Allows coverage below 1.00 | Select lenders only, leverage and terms adjusted |
| Lower price | Shrinks both ceilings | Seller has to agree |
Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Those are different paths, not one program with a moving floor. No-ratio qualification is available only through select lenders, generally for borrowers who already own a primary residence.
Honestly, the stronger play on a rent-controlled building is often the larger down payment, not the exotic structure. It’s the one lever that doesn’t depend on a lender’s appetite.
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.
What Does the Cash Side Look Like?
Cash to close on a $2M triplex is the down payment, closing costs, and reserves. All three count.
The down payment follows the LTV tier. At 75%–80% LTV on a purchase, that’s 20%–25% down. Select high-leverage programs reach 85% LTV with roughly a 700+ score, though they’re a stretch on a coverage-tight San Francisco building. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Credit matters at this size. A 620 floor exists in parts of the network, and most programs want around 660. At 700+, the strongest leverage tiers open up.
Reserves are the line investors forget. They run about 6 months of PITIA on most files. Above $1,500,000, they typically step up to about 9 months. A $2M purchase price puts the loan amount near or above that line, so the higher band is worth planning for. Reserves documentation needs to show the funds are liquid and seasoned in the borrower’s accounts.
For loans above $2,500,000, the network generally holds to 30-year fixed structures. A $2M loan sits below that line. The spine product is still the 30-year fixed, with extended terms and ARM structures available through select lenders.

What If the Price Is Above What the Rent Supports?
Start with the reverse math. Take the rent used for review, divide by the coverage floor, and see what PITIA that supports. Compare it to the PITIA on the loan you want. The gap tells you how much to adjust.
The options, in order of how often they work:
1. Bring more cash. Drop the LTV until the ratio clears.
2. Negotiate price. Both ceilings fall together.
3. Test an interest-only structure. It can lift the ratio mechanically, through select lenders.
4. Look at a sub-1.00 program. Available through select lenders in the network, with leverage and terms adjusted.
5. Document market-rent renewals. Only if they’re signed before the appraisal and the tenant is willing.
Each of these goes to the lender for review. None is a promise. Eligibility review depends on credit, property review, and lender guidelines.
How Should an Investor Decide?
Decide off the coverage ceiling first, not the LTV headline. In high-price, rent-controlled markets, rent usually binds before leverage does. An investor who budgets for the 80% number can end up bringing far more cash than planned.
Get the real tax basis before running anything. Ask the appraiser to flag in-place versus market rent per unit. Line up leases and a rent roll early. Budget the 9-month reserve step-up.
Don’t read a 1.00x as safe. Maintenance, vacancy, and a rent-controlled tenant who stays ten more years all sit outside that number.
Tax treatment varies; consult a qualified professional.

Frequently Asked Questions
Can a DSCR loan finance a triplex in San Francisco?
Yes, subject to lender guidelines. A triplex is a standard two-to-four unit residential income property. It must be non-owner-occupied, in good condition, and supported by rent that clears the coverage test.
Is $2M too large for a standard DSCR program?
No. Standard programs run up to $3,000,000. The practical changes at $2M are the reserve step-up to about 9 months and stricter attention to credit and coverage. Above $2,500,000, the network generally holds to 30-year fixed structures.
Which rent does the lender count on a rent-controlled unit?
Usually the lower of the signed lease and the appraiser’s market rent, tested unit by unit. A long-tenured tenant’s low lease holds that unit down. A vacant unit counts at market rent. Confirm how the lender treats the appraiser’s figure for controlled units.
Will the seller’s property tax bill work for underwriting?
No. California reassesses on sale, so the buyer’s tax is built on the purchase price. Using the seller’s bill understates PITIA and overstates the ratio.
Can I buy the triplex in an LLC?
Often, depending on program guidelines. Expect entity documents, such as the operating agreement and good-standing evidence, along with a personal guaranty in most cases.
Does a 1.00x ratio mean the building cash flows?
No. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex fall outside it.
