The Quick Read: It depends on the property, because a DSCR loan compares monthly rent to the full payment of principal, interest, taxes, insurance and HOA dues, and San Antonio rents are modest while non-homestead taxes and insurance run heavy, so many rentals land near 1.00x and some fall below it. The swing factor is usually the escrow items, not the loan itself.
- The test is rent divided by full PITIA, not rent divided by principal and interest.
- The rent that counts is generally the lower of the signed lease and the appraiser’s market rent.
- San Antonio rents are soft, and property taxes and insurance are the inputs most likely to push a file under 1.00x.
- Clearing the ratio does not mean the property cash flows. Repairs, vacancy, management and utilities sit outside the test.
- Coverage below 1.00x is available through select lenders in the network, with leverage and terms adjusted.
How Does the DSCR Test Work on a San Antonio Rental?
The test is one division problem. Take the monthly rent the lender will count and divide it by the full monthly housing payment. For one-to-four unit rentals, that payment is principal, interest, property taxes, insurance and any HOA dues. Lenders call the bundle PITIA.

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.
A result of 1.00x means the rent equals the payment. Above 1.00x, rent exceeds it. Below 1.00x, the payment is larger than the rent.
| Ratio | What it means | What changes on the file |
|---|---|---|
| Below 1.00x | Rent is short of the payment | Select-lender path, leverage and terms adjusted |
| About 1.00x | Rent equals the payment | Where many select programs start |
| Above 1.00x | Rent exceeds the payment | Stronger ratios open better pricing and leverage |
Here is the point most first-time investors miss. 1.00x is where many select programs start, and it is a floor for those programs only. A separate select-lender path takes coverage below 1.00x, with leverage and terms adjusted. These are different paths, not one program with a moving floor.
This test is a business-purpose investor test. DSCR loans are designed for non-owner-occupied investment properties, so the file is reviewed differently from an owner-occupied mortgage. The loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines.

What Do San Antonio Rents Look Like?
San Antonio rents are modest compared with the national median, and they have been drifting lower. Apartment List puts the citywide median across all unit types at $1,121. That is down 4.3% year over year and roughly 19% below the national median. It also shows San Antonio falling faster than both the Texas average (down 2.1%) and the national average (down 0.4%).
That median leans toward apartments, so it understates what a house rents for. Zumper puts the median single-family house rent at $1,749 and the all-bedroom median at $1,532.
The figures differ because they measure different things. Some track apartments, others houses. Some use asking rents, others achieved rents. The geographies differ too. A fair working range for a San Antonio rental is roughly $1,100 to $1,800, depending on the source and the property type. Pull comps for the specific property before you trust any of them.
The soft trend matters for one reason. A DSCR file is underwritten on today’s rent, but a buyer holding the property is exposed to next year’s. Investors should stress-test the ratio at a lower rent than the listing suggests.
Why Do Taxes and Insurance Decide So Many San Antonio Files?
Taxes and insurance are fixed inputs that the borrower cannot negotiate down at the closing table. They carry more weight in the denominator than the interest cost on many files here.
Take property tax first. A Bexar County bill stacks the county, city, school district and other taxing units. Property Tax Almanac says school district tax is roughly half the bill for a typical San Antonio address. That is a third-party estimate, so price the actual parcel before relying on it.
A lower number circulates too. Abode Money shows a Bexar effective rate of 1.73%. That figure is a Census-based average that includes homesteaded owners. Investor properties get no homestead relief, so the real rate on a rental runs higher than that average. A buyer who uses the lower number will overstate the ratio.
Insurance works the same way. Investor commentary points to sharp increases tied to weather claims, as Sell to Home Pros notes. That is direction, not a number. The practical habit is simple: get a real insurance quote for the actual property before the ratio is run, not an estimate from last year.
Non-homestead values can also be reassessed on a regular cycle, so a bill can step up after purchase. A file that clears 1.00x by a thin margin at closing can slip under it after the first reassessment or insurance renewal.
One local market guide from Harkin Realty says many financed single-family rentals show thin or negative cash flow once realistic taxes, insurance and vacancy are counted. That matches what the ratio shows on many files in this city.
Which Rent Does the Lender Count?
When a lease sits above what the appraiser finds in the market, lenders generally count the lower market rent, which can catch borrowers off guard.
| Situation | Rent used | Effect on the ratio |
|---|---|---|
| Lease above market | Appraiser’s market rent | Ratio is trimmed to market |
| Lease below market | The lease | Ratio is held at the lease figure |
| Vacant, rent-ready property | Appraiser’s market rent | Comp quality drives the result |
The appraiser documents market rent on a rent schedule. Single-family files use Form 1007, and two-to-four unit files use Form 1025. Those are forms the non-QM market borrowed. Agency rules do not govern DSCR loans. The form names are simply how the rent gets documented.
Two practical points follow. First, a landlord who signs a family member or friend at a discount hands the lender a lower number, and the lease caps the ratio. Second, a landlord who signs a tenant above market gains nothing on the ratio, because the appraiser’s figure wins.
The documents a San Antonio file usually needs are the appraisal with the rent schedule, the lease if the property is leased, the insurance quote or declarations page, tax figures, and HOA dues if there are any. A DSCR loan reduces income paperwork. It does not remove paperwork.
How Does a Passing File Compare With a Failing One?
Run the numbers on two modeled files. These ratios are illustrative assumptions, not market data.
Picture a single-family house with market rent near the upper end of the local range, a moderate purchase price and a standard down payment. Taxes and insurance are priced on the actual parcel. The ratio comes back around 1.15x. That file clears 1.00x with some cushion, and a lender can price it well.
Now picture a second house at the same rent but a higher purchase price. The loan balance is larger, so the interest component is larger, and the tax bill rises with value. Insurance renews higher. The ratio comes back around 0.92x. Same rent, same city, different result.
The failing file has four levers.
| Lever | Effect on the ratio |
|---|---|
| Larger down payment | Lowers the loan balance and the payment, lifts the ratio |
| Lower purchase price | Lowers the loan balance and the tax bill |
| Insurance re-shopping | Lowers the escrow line |
| Better rent evidence | Lifts the appraiser’s figure only if comps support it |
A larger down payment helps the ratio, but it never erases other rules. Leverage caps, credit floors, reserve rules and property eligibility still apply. The strongest files clear both tests: enough equity and enough rental coverage.
What Happens When Rent, Taxes or Insurance Move?
A sensitivity check shows how fragile a thin file is. The numbers below are modeled around a 1.10x starting point.
| Change | Modeled ratio |
|---|---|
| Starting point | About 1.10x |
| Rent falls on the appraiser’s comps | Low 1.0x range |
| Taxes step up after purchase | Around 1.04x |
| Insurance renews higher | Around 1.02x |
| Rent falls and escrow rises together | Below 1.00x |
Insurance and tax increases together can move a ratio further than a drop in the interest component would. A file sitting at 1.10x has little room for all three moves at once. That is why the lender’s number and the investor’s stress test should not be the same number.
You can also back-solve. Start with the rent the lender will count and ask what payment that rent supports at 1.00x. Whatever room remains after taxes, insurance and HOA dues is what the loan can carry. If the loan on a given price carries more than that, the file is short, and the price or the down payment has to move.
Does Passing the Test Mean the Property Cash Flows?
No. The DSCR test compares rent to PITIA only. Repairs, vacancy, management, utilities and capital expenses sit outside the calculation. A property can clear 1.00x and still lose money once those costs are counted. One lender-side guide, Honest Casa, says operating costs commonly consume a large share of gross rent on long-term rentals. Treat that as direction, not a figure for your property.
Gross yield claims for San Antonio vary widely from one source to the next, and net yields run lower than gross. Do not underwrite a purchase on a single yield claim.
The South and West sides are lower priced and aimed at cash flow. The medical-center areas are pricier, thinner on yield and stronger on appreciation. The same rent can pass in one area and fail in another, because the price and the tax bill move with the address.
What Can an Investor Do If the Ratio Falls Short?
Start with the ratio, not the property. If it falls short, fix the inputs that are in your control before looking at other paths.
1. Reprice the insurance quote and confirm the tax figure on the actual parcel.
2. Test a larger down payment or a lower purchase price and see where the ratio crosses 1.00x.
3. Check whether the appraiser’s market rent supports a stronger number than the lease shows.
4. If it still falls short, ask about the select-lender path below 1.00x. It is available through select lenders in the network, with leverage and terms adjusted.
A separate structure is a no-ratio loan. It is available only through select lenders, generally for borrowers who already own a primary residence.
One more point on pooling. One property’s rent does not cover another property’s loan. Each file is tested on its own rent and its own payment.
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 Do Program Terms Look Like Across the Network?
Program mechanics vary by lender, and the network sees many of them. These are typical ranges, subject to lender guidelines, credit approval and property review. They are not commitments to lend.
- Purchase leverage on an investment property usually lands at 75%-80% LTV, which means 20%-25% down. Select high-leverage purchase programs reach 85% LTV on an investment property with roughly a 700+ score.
- Cash-out refinance on a standard rental tops out around 75% LTV across most of the network, with about 6 months of seasoning as the common expectation.
- A 620 credit floor exists in parts of the network. Most programs want around 660, and 700+ unlocks the strongest leverage tiers.
- Loan sizes run up to $3,000,000 on standard programs, with smaller balances routed through select lenders. Above $2,500,000 the network generally holds to 30-year fixed structures.
- Reserves commonly run around 6 months of PITIA, and loans above $1,500,000 typically step up to about 9 months. They vary by lender, leverage, loan size and transaction type.
- Term structures center on the 30-year fixed, with 40-year and interest-only options through select lenders, and ARM structures for investors who want them.
- Manufactured homes, log homes and barndominiums are not offered in the network’s DSCR programs.
Short-term rentals are scored differently. Purchase leverage tops out at 75% LTV on a short-term rental, with a 640+ score, about 12 months of hosting history and a 1.00 coverage floor on purchases. 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. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Tax treatment varies; consult a qualified professional.
Key Terms Defined
DSCR: The debt service coverage ratio, which here means monthly rent divided by the monthly PITIA.
PITIA: Principal, interest, property taxes, insurance and HOA dues, the full monthly housing payment.
Market rent: The rent an appraiser documents for the property based on comparable rentals.
Non-homestead property: A property that is not the owner’s primary residence, so it carries no homestead tax relief.
Reserves: Liquid funds the borrower holds after closing, commonly counted in months of PITIA.
Frequently Asked Questions
Is rent divided by principal and interest enough to pass a DSCR test?
No. The lender divides rent by the full PITIA. Counting only principal and interest overstates the ratio, and in San Antonio the tax and insurance lines are large enough to turn a pass into a fail.
Can a signed lease above market rent lift the ratio?
Generally not. The counted rent is typically the lower of the lease and the appraiser’s market rent, so a lease above market is trimmed to the appraiser’s figure. A lease below market holds the ratio at the lease number.
What if a San Antonio rental comes in below 1.00x?
Some files still move forward. Coverage below 1.00x is available through select lenders in the network, with leverage and terms adjusted. A larger down payment or lower price may also lift the ratio over the line.
Does the DSCR test replace personal income documents?
It reduces them. The file still needs an appraisal, insurance, reserves documentation, and a lease when the property is leased.
Does clearing the ratio mean the property is profitable?
No. The ratio compares rent to the housing payment only. Repairs, vacancy, management and utilities are outside it, so run a separate operating budget before buying.
