The Quick Read: A DSCR lender sizes your loan as the smaller of two ceilings. One is a leverage cap on the property’s value. The other is the largest loan the property’s rent can carry. On a $1.5M San Diego purchase, the rent test often binds first, so the loan can land well under the headline leverage cap.
- Leverage cap: Most purchase files land at 75%–80% LTV on an investment property. Select high-leverage programs reach 85% LTV with roughly a 700+ score, subject to lender guidelines.
- Rent test: The lender divides rent used for lender review by the full monthly payment. A 1.00 ratio is where many select programs start, and stronger ratios open better terms.
- Expensive markets: A big loan plus reassessed property taxes can outrun typical rents, which shrinks the loan the rent supports.
- Ways to close the gap: A larger down payment, an interest-only structure, a property with higher supportable rent, or a sub-1.00 path through select lenders with terms adjusted.
- A warning: Clearing 1.00 does not mean the property cash flows. Repairs, vacancy, management, and utilities sit outside the math.
San Diego is the worked example here, not a national benchmark. The mechanics apply to any high-priced market.

What Does a DSCR Lender Look At First?
A DSCR loan qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. DSCR stands for debt service coverage ratio. It is monthly rent used for lender review divided by the monthly housing payment on the loan. That payment is called PITIA: principal, interest, taxes, insurance, and association dues.
Credit, reserves, and the appraisal still matter. What changes is that your personal income documentation is not the centerpiece. The property’s income is.
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. For the full picture of how these loans work, see Lendmire’s complete DSCR loans guide.
One point trips up a lot of first-time investors. The ratio does not set the loan amount. It tests a loan amount someone has already proposed. So the real question is which proposed amount passes both tests.
How Is the Loan Amount Set, Step by Step?
The loan is the lower of the LTV ceiling and the rent ceiling. LTV, or loan-to-value, is the loan as a percentage of the property’s value. The six steps below show how the underwriter gets to the lower number.
Step 1: Fix the value. The appraisal sets value. On a purchase, the lender applies LTV to the lower of the price or the appraised value. If the appraisal comes in under $1.5M, the leverage cap shrinks with it.
Step 2: Fix the rent used for lender review. Rent used for program review is typically the lower of the signed lease and the appraiser’s market-rent opinion. Your listing price for the rent does not count. Neither does your hope. For a single-family home, that opinion comes on a rent schedule (Form 1007). For a small 2–4 unit property, it comes on an operating income statement (Form 1025).
Rent here means gross rent. Vacancy and management costs are not subtracted.
For context only, Apartment List puts San Diego’s citywide median rent across all unit sizes at $2,317, up 0.5% year over year. Doorstead reports a metro single-family median of $4,317 and an all-types median of $3,132. These are medians. Your property’s own comparable rentals, as the appraiser reads them, decide the figure used.
Step 3: Build the payment. Add principal, interest, taxes, insurance, and association dues. Principal and interest depend on the loan size. That is why the test needs a proposed loan to work on.
Step 4: Reprice the taxes. California reassesses a property when ownership changes. The California State Board of Equalization describes a 1% base rate, plus voter-approved debt levies, reset on a change of ownership. Those added levies can push the total above 1%, and they differ by location.
The practical rule: tax the purchase at the new price, not at the seller’s old bill. The seller’s bill reflects a much lower assessed value. Using it is a common modeling error. For San Diego, confirm the expected tax figure, including local add-ons, with the county assessor or a qualified local tax professional, then budget for that.
Step 5: Back-solve the maximum payment. Divide rent used for eligibility review by the minimum coverage ratio. That gives the most the full payment can be. Subtract taxes, insurance, and association dues. What remains is the room for principal and interest. That room converts into a maximum loan amount. In plain terms:
- The maximum payment is the rent used for the lender’s review, divided by the minimum coverage ratio.
- The room for principal and interest is the maximum payment, less taxes, insurance, and association dues.
Step 6: Compare the two ceilings. Set the rent-supported loan next to the leverage cap. The lower one wins.
Which Limit Binds on a $1.5M Purchase?
In a high-price, moderate-rent market, the rent ceiling often binds first. The leverage cap only binds when the rent is strong enough to carry a loan at 75%–80% of price. That is a big ask at this price point.
Run the numbers on three modeled rent levels. These are assumptions for illustration, not market facts.
| Rent level (modeled) | Binding limit | Result |
|---|---|---|
| Strong | Leverage cap | Loan reaches 75%–80% of price |
| Middling | Rent test | Loan falls below the cap |
| Weak | Rent test | Needs a sub-1.00 path or much more equity |
Say the rent test supports a loan equal to only 55% of the price. That is a modeled assumption. The buyer’s down payment then becomes 45% of the price, not the 20%–25% the leverage cap alone would suggest. The extra cash is not a penalty. It is the gap the rent cannot cover.
Notice what this does to the buyer’s plan. You may budget for a 25% down payment, then learn the property needs far more. Size the rent test before you write an offer, not after. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The citywide medians above hint at the pressure. A loan near 75% of $1.5M, plus taxes reset to the new price, is a heavy payment. Typical rents in the city’s data are modest by comparison. A $1.5M home with a standout rent comp set, or a multi-unit property, changes that picture.
What If the Rent Doesn’t Cover the Payment?
You have five levers when the rent falls short. Each one trades something for something else.
| Lever | What it does | Trade-off |
|---|---|---|
| Bigger down payment | Shrinks loan and payment | More cash tied up |
| Interest-only period | Replaces PITIA with ITIA | Balance does not pay down |
| Higher supportable rent | Raises the numerator | Needs a different property or comps |
| Sub-1.00 path | Accepts coverage under 1.00 | Leverage and terms adjusted |
| No-ratio path | Skips the ratio test | Select lenders only, narrower borrower pool |
Bigger down payment. A larger down payment lowers the payment and lifts the ratio. It does not erase anything else. Leverage caps, credit floors, reserve rules, and property eligibility all still apply. The strongest files clear both tests: enough equity and enough rental coverage.
Interest-only structures. These are available through select lenders in the network. The qualifying payment becomes ITIA: interest, taxes, insurance, and association dues. With no principal in it, the same rent produces a higher ratio. Other structures exist too. The spine of most programs is the 30-year fixed, but select lenders offer 40-year terms, and ARM structures exist for investors who want them.
Coverage below 1.00. Here the two paths separate clearly. A 1.00 ratio is where many select programs start. A separate path takes coverage below 1.00 through select lenders in the network, with leverage and terms adjusted. Expect lower LTV and a different pricing profile, and expect stronger credit and reserves to matter more.
No-ratio structures. These are available only through select lenders, generally for borrowers who already own a primary residence. They are not a loophole. Qualification still rests on credit, reserves, the appraisal, and the lender’s view of the file.
Where Does the General Rule Break?
Several edge cases change the math. Know them before you assume the standard path applies.
Short-term rentals. Rent may come from an income projection instead of a long-term rent schedule. Purchase leverage tops out at 75% LTV, while refinances and cash-out on short-term-rental collateral both run around 70%. Expect a 640+ score, about 12 months of hosting history, and a 1.00 coverage floor on a purchase. 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. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Purchase versus refinance. On a standard rental, cash-out refinance tops out around 75% LTV across most of the network. About 6 months of seasoning is the common expectation. Seasoning is the wait between buying a property and refinancing it. A refinance also values the property by appraisal, so the same rent-versus-payment test applies to the new loan. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Large loans. Loans reach up to $3,000,000 on standard programs, and balances below the standard-program minimum route through select lenders in the network. Above $2,500,000 the network generally holds to 30-year fixed structures. A $1.5M purchase sits in the upper-middle of that range. Larger balances tend to draw tighter overlays, which means stricter lender rules layered on top of base guidelines. Lender choice narrows as size grows.
Property type. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered through the network’s DSCR programs. A $1.5M San Diego house is a different story, but check eligibility before you fall in love with an unusual property.
Entity titling. Many investors buy through an LLC. Whether that works depends on program terms and the lender, as does how recourse is handled. Confirm both before you sign a contract.
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.
How Much Cash, Credit, and Reserves Do You Need?
Expect 20%–25% down on most purchase files, or 15% down on select high-leverage programs with roughly a 700+ score. Those are typical ranges, subject to lender guidelines. A rent shortfall can push you above them, as the scenario above showed.
Credit works in tiers. A 620 floor exists in parts of the network. Most programs want around 660. A 700+ score unlocks the strongest leverage tiers. Better coverage and better credit together open better pricing and more leverage.
Reserves are liquid funds the lender wants you to keep after closing. They vary by lender, leverage, loan size, and transaction type. They commonly run around 6 months of PITIA. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Loans above that size typically step up to about 9 months. On a $1.5M purchase, the loan itself usually stays under that line.
What Does the Investor Decision Look Like?
Start with the rent test, not the leverage cap. Get a realistic rent figure from comparable rentals. Add the reassessed taxes, insurance, and dues. Work backward to the loan the rent supports. Then decide whether the down payment that implies still makes the deal worth doing.
Think this through honestly. A high-priced property can make sense for appreciation or a long hold. But a thin ratio at purchase leaves little room for a rent dip or a cost spike. The stronger play is often the property you can carry with a margin, not the one that barely clears.
Remember what the ratio measures. It compares rent to the payment. It does not count repairs, vacancy, management, utilities, or capital expenses. A file can clear 1.00 and still lose money each month.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Key Terms Defined
- Rent used for financing review: The monthly rent the lender uses in the ratio, typically the lower of the lease and the appraiser’s market-rent opinion.
- ITIA: Interest, taxes, insurance, and association dues. It replaces PITIA when the loan has an interest-only period.
- Seasoning: The waiting period between buying a property and refinancing it, commonly about 6 months for a cash-out.
- Reserves: Liquid funds you keep after closing, usually counted in months of PITIA.
- Overlay: An extra lender rule layered on top of base program guidelines, often tighter on larger loans.
Frequently Asked Questions
What is the largest DSCR loan I can get on a $1.5M purchase?
It is the lower of two numbers. The leverage cap is typically 75%–80% of the lower of price or appraised value on a purchase. The rent test is the largest loan whose full payment the rent used for program review can cover. Standard programs reach $3,000,000, so loan size is not the limit here. The rent test usually is.
Can a DSCR loan lend more than 80% of the price?
On a purchase of an investment property, select high-leverage programs reach 85% LTV with roughly a 700+ score. That is the exception, not the norm, and it still requires the rent to cover the payment. Cash-out on a standard rental tops out around 75% LTV. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Does coverage under 1.00 end the deal?
Not necessarily. Sub-1.00 coverage is available through select lenders in the network, with leverage and terms adjusted. A no-ratio path exists only through select lenders, generally for borrowers who already own a primary residence. Both usually need more down and stronger credit. Qualification stays subject to lender guidelines.
Do I still need to document my personal income?
Not as the centerpiece. The loan is reviewed primarily on property-level rental income covering the payment. Credit, reserves, the appraisal, and the rent schedule all still get reviewed.
If my ratio clears 1.00, does the property make money?
Not automatically. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses are outside it. Treat the ratio as an approval test, then run your own full cash-flow budget.
