The Quick Read: Getting a DSCR loan on a San Antonio rental means showing that the property’s rent covers its full monthly obligation (principal, interest, taxes, insurance, and any HOA dues), then clearing the credit, reserve, and property checks that sit around that ratio. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.
- Most purchase files across the wholesale network land at 75%-80% LTV on an investment property.
- Coverage of 1.00 is where many select programs start; stronger ratios open better pricing and leverage.
- Most programs want a credit score around 660, with a 620 floor in parts of the network.
- In San Antonio, taxes and insurance often decide whether the ratio clears.
- Reserves commonly run about 6 months of PITIA, subject to loan size and leverage.
What Is a DSCR Loan, and Who Is It For?
A DSCR loan is a non-QM investment-property mortgage that looks at the rental’s income instead of the borrower’s personal-income documentation. HousingWire’s non-QM guide describes it as the main non-QM tool for investors, with rental income divided by monthly housing expense as the formula.

Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. Qualifying income for short-term rentals varies by program — some use appraisal market rent, others use documented STR history or projections — and is confirmed in underwriting. Not a Loan Estimate, approval, or commitment to lend. Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
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.
The profile that benefits most: self-employed investors whose tax returns understate income, LLC-based operators, and anyone whose conventional debt-to-income math has stopped working. Conventional financing may still be the better call for a W-2 borrower with one or two rentals and clean returns. The conventional lane often costs less. DSCR earns its place when scaling, because each loan is judged on its own property rather than on your total personal debt load.

Key Terms Defined
DSCR (debt service coverage ratio): The property’s monthly rent divided by its monthly PITIA, expressed as a ratio.
PITIA: Principal, interest, taxes, insurance, and association dues. This is the full monthly obligation in the denominator.
Form 1007: The appraiser’s single-family comparable rent schedule, which produces a market rent opinion.
Form 1025: The small residential income report used for 2-4 unit properties, with each unit’s rent analyzed.
Seasoning: How long a borrower has held a property before a cash-out refinance. About 6 months is the common expectation.
Reserves: Liquid assets, measured in months of PITIA, that you hold after closing.
How Does Underwriting Actually Treat a San Antonio Rental?
The underwriter runs two tests at once: enough rental coverage, and enough equity and credit. The strongest files clear both. A larger down payment lowers the payment and can lift the ratio, but it never erases leverage caps, credit floors, reserve rules, or property eligibility.
Here is the sequence, step by step.
1. Define the transaction. Choose a purchase, rate-and-term refinance, or cash-out refinance. Confirm the property is non-owner-occupied and decide whether you will hold title personally or in an entity. For LLC vesting, eligibility depends on program guidelines.
2. Order the appraisal with a rent schedule. The appraisal sets value (which drives LTV) and market rent (which drives coverage). The Form 1007 rent schedule is prepared by the appraiser as an attachment, with three rental comparables and a reconciled monthly market rent.
3. Pick the rent used for lender review. On a vacant purchase, the appraiser’s market rent typically sets the number. On a leased property, programs often compare the lease with market rent and use the lower figure. Each program decides this, and a signed lease above market may not be fully credited.
4. Build PITIA. Principal and interest on the proposed loan, plus taxes, insurance, and HOA dues.
5. Divide rent by PITIA. A result of 1.00 means rent equals the payment. Above 1.00 is a cushion; below 1.00 is a shortfall.
6. Underwrite the rest of the file. Credit, assets and reserves, entity documents, title, insurance, and the property itself all get reviewed. Personal income documents are not the focus, but this is still underwriting.
One definition trap: commercial real estate uses net operating income divided by debt service. Residential investor DSCR uses gross rent against PITIA. Investors from a commercial background often miss this, so confirm the program’s definition up front.
What Do Lenders Look For on the Borrower Side?
Across the wholesale network, the borrower-side numbers cluster in predictable ranges, though every file is underwritten individually.
| Factor | Typical range |
|---|---|
| Purchase LTV | 75%-80% on an investment property |
| High-leverage select programs | Up to 85% LTV with roughly a 700+ score |
| Cash-out refinance | Around 75% LTV, about 6 months seasoning |
| Credit score | 620 floor in parts of the network; most want about 660; 700+ unlocks top tiers |
| Loan size | Up to $3,000,000 on standard programs |
| Reserves | About 6 months PITIA; about 9 months above $1,500,000 |
Reserves flex. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived by some lenders. Above $2,500,000, the network generally holds to 30-year fixed structures. The spine of the product is the 30-year fixed, with 40-year terms and interest-only periods available through select lenders, and ARM structures for investors who want them.
Not offered: manufactured homes (single- and double-wide), log homes, and barndominiums fall outside these programs.
Why Do Taxes and Insurance Decide San Antonio Files?
Taxes and insurance are the two lines that most often swing a San Antonio deal. The denominator is more than a mortgage payment, and in Bexar County the escrow items are heavy.
Local realtor analysis from Harkin Realty suggests budgeting roughly 2% of value for property taxes unless you pull the parcel’s exact combined rate, and notes that many financed single-family rentals show thin cash flow once realistic taxes, insurance, and vacancy are included. The same source points to rent-to-price ratios that look better than Austin’s, with taxes eroding part of that edge. Get an actual insurance quote early, since hail exposure and roof age move premiums, and ask about flood coverage where relevant.
There is a Texas-specific wrinkle worth modeling. The 20% appraisal “circuit breaker” limits yearly value growth on non-homestead property valued at $5 million or less, as the Baker Institute explains. But the cap does not run with the property: a new owner does not inherit the seller’s capped value, so a purchase can reset taxable value. Build taxes in PITIA from the expected post-purchase value, not the seller’s current bill. Secondary tax sources also describe the cap as scheduled to sunset at the end of 2026 absent legislative action, so confirm current law with the Texas Comptroller before relying on it.
Skip using the seller’s tax bill as your input. It is the most common way San Antonio files come in thinner than planned.
How Do You Screen a Deal Before You Make an Offer?
Back-solve the ratio before you write the offer. Start with the rent the property would plausibly support, then work out the maximum PITIA that keeps coverage at your target, then compare it with taxes, insurance, and the loan size you expect.
Consider three modeled scenarios, all assumptions rather than market facts:
- Passes: A single-family purchase at 75% LTV where rent covers the full obligation with room to spare, landing around 1.2x. Strong files like this tend to access better leverage and pricing.
- Borderline: Rent just matches PITIA, landing near 1.00x. This sits right at the floor for many select programs, so a modest drop in appraised rent or a higher insurance quote can tip it.
- Fails: Coverage lands under 1.00x because taxes reset higher than assumed. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Worth asking first: should you use it? If the property has a real appreciation story, a sub-1.00 structure can be defensible. If you are reaching for it because no property in your target submarkets pencils, re-examine the submarket, not the loan type.
The levers for a short ratio, roughly in order of effect: a larger down payment (lowers the payment), a different property, stronger rent evidence, a tax protest or corrected tax estimate, and an interest-only period through a select lender.
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 Happens If the Appraiser’s Rent Comes in Low?
The appraiser’s rent is an opinion, and opinions can be challenged. If the 1007 comes in below your assumption, a reconsideration request with specific, better rental comps may help. Better still, assemble a comp package before the appraisal so the appraiser sees it first.
For market context, apartment-weighted data from RentCafe shows San Antonio average rents softening year over year, and those figures understate single-family rents. Treat any pre-appraisal ratio as an estimate, not a result.
Where Does the General Rule Break?
Short-term rentals. The 1007 was not designed for properties used as short-term rentals. Fannie Mae’s appraiser guidance says the form needs monthly-leased comparables, and multiplying a nightly rate by 30 is incorrect. STR files therefore run on platform booking data. In the network, STR purchases go up to 75% LTV, refinances around 70%, and cash-out up to 70% on short-term-rental collateral, with a 640+ score, about 12 months of hosting history, and a 1.00 coverage floor on both purchases and refinances. 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.
2-4 units. Rent analysis moves to Form 1025, which values each unit separately.
Vacant or transitional properties. No-ratio qualification is available only through select lenders, generally for borrowers who already own a primary residence.
Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation. A property can pass at 1.05 and still lose money in a bad year.
What Does the Process Look Like in Practice?
Once you have run the numbers, the sequence is: get pre-qualified with the address, price, expected rent, and credit range; go under contract; order the appraisal with the rent schedule; assemble entity documents, insurance, and proof of funds and reserves; then move through underwriting and title. What you generally do not need: personal-income documentation, subject to the program. Out-of-state investors can use these loans, and remote closings with local property management are common.
Lendmire, a DSCR-focused mortgage broker with investor programs in 40 states plus Washington, D.C., arranges these files through select lenders in its wholesale network. If you are weighing this route against a traditional lender on a San Antonio purchase, Lendmire’s comparison of a DSCR loan versus a bank loan for a rental purchase lays out the tradeoffs.
DSCR is also where the conventional lane runs out. If you hold more than a handful of financed properties, or if your returns don’t support rental income add-backs, DSCR becomes the practical path. If you hold one rental and have strong employment income, run both comparisons first.
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.
Frequently Asked Questions
Do I need tax returns or W-2s to get a DSCR loan?
Generally not. Credit, assets, reserves, title, insurance, and the property are still reviewed.
What credit score do I need?
Most programs in the network want around 660, and a 620 floor exists in parts of it. A 700+ score unlocks the strongest leverage tiers, including select programs up to 85% LTV on a purchase.
How much down payment is typical on a San Antonio purchase?
Most files land at 75%-80% LTV, which means roughly 20%-25% down on an investment property. Select high-leverage programs reach 85% LTV with about a 700+ score.
Can an out-of-state investor get one?
Yes, subject to program guidelines. Underwriting is property-based, so where you live matters less than the rent, credit, reserves, and collateral.
Can I buy in an LLC?
Often, depending on program guidelines. Entity documents are part of the file.
