The Quick Read: You size the deal by starting with the rent a lender will count, dividing it by your target coverage ratio to find the largest full monthly payment the property can carry, and then checking that the loan, taxes, insurance, and association charges all fit under that ceiling.
- The test is gross monthly rent divided by PITIA: principal, interest, taxes, insurance, and association dues.
- Select programs in Lendmire’s wholesale network start at 1.00 coverage. Stronger ratios open better pricing and leverage.
- Orlando’s pressure sits in the bottom of the fraction: tax reset after a sale, landlord insurance, and non-ad valorem charges.
- Clearing the ratio is a lender test, not proof the property makes money.
- A bigger down payment, a lower price, or a different property are the main fixes when the number falls short.
What Does “Sizing” Mean on a DSCR Loan?
Sizing means running the coverage test backwards. A normal DSCR calculation takes a known payment and asks whether rent covers it. Sizing takes the rent and asks how big a payment, and therefore how big a loan, the property can support.

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.

For 1-4 unit rentals, the ratio is gross monthly rent divided by the full monthly payment. A result of 1.00 means rent exactly covers the payment. Anything below means a shortfall, as the definition of the debt service coverage ratio lays out.
One trap: many pages show a different formula. Commercial lenders divide net operating income by annual debt service, and that same reference puts typical commercial bank expectations at roughly 1.15 to 1.35 on that version. That is a different test on a different product.
Lendmire is a broker. It arranges these loans through select lenders in its wholesale network, and the lenders set final eligibility. The numbers below are typical ranges, not promises. The complete DSCR loans guide covers the full program picture.
The Five Steps, Start to Finish
Here is the method to follow. Do the steps in order.
1. Pick the rent a lender will count. Not the rent you hope for. The one the appraisal and lease will support.
2. Choose your target coverage. Many files start at 1.00. A cushion above that is safer.
3. Divide rent by the target. That gives the largest full payment the property can carry.
4. Subtract taxes, insurance, and association charges. What remains is the room for principal and interest.
5. Convert that room into a loan amount, then compare it to the leverage cap. The final loan is the smaller of the coverage-supported amount and the amount the LTV cap allows.
Step 3 is easy to do in your head. Divide by 1.00 and the payment ceiling equals the rent. Divide by 1.20 and the ceiling is about 83% of the rent. Divide by 1.25 and it drops to 80%. Every step up in target coverage trims the payment room.
Step 5 is where the calculator helps. It turns the payment ceiling into a loan amount at current pricing. Treat its output as an illustrative estimate, not a quote.
Which Rent Counts?
The rent the lender uses is rarely the number in your pro forma. The appraisal supplies a market-rent opinion. On a single-family home or condo, that comes from the rent schedule form (Form 1007). On a two-to-four unit building, the appraiser completes Form 1025 with rent per unit.
Many programs placed through the network use the lower of the actual lease and the appraised market rent. That varies by lender, so confirm it for your file. Investor education from True Cap points out that a market-rent opinion below your lease can push the ratio into a lower pricing tier.
| Situation | Rent basis typically used | Main risk |
|---|---|---|
| Leased at market | Lease or appraised rent, often the lower | Appraisal comes in under lease |
| Leased below market | Often capped at the lease | Ratio looks weaker than the property’s potential |
| Vacant | Appraised market rent | Appraiser’s number is the only number |
| Month-to-month or expired lease | Often falls back to market rent | Lender treats the lease as unreliable |
The practical rule: size to a rent you can defend, then leave margin. If your deal only works at the top of the rent range, it does not work.
What Goes in the Payment in Orlando?
Orlando is a denominator market. A rental can show an attractive rent-to-price relationship and still miss the ratio because the payment side runs heavy. Four lines do most of the damage.
| Payment line | Why it varies in Central Florida | Verify before offering |
|---|---|---|
| Property taxes | Reset after a sale | Price times local millage |
| Insurance | Roof age, wind exposure, landlord policy | A real quote on that address |
| HOA dues | Resort and gated communities | Governing documents |
| CDD and similar charges | Fixed per parcel, billed on the tax bill | Full tax bill, non-ad valorem section |
Taxes. Do not size from the seller’s current tax bill. Florida limits yearly growth in assessed value on non-homestead property, but the Orange County Property Appraiser explains that the property is reassessed at full market value the year after a sale. The same FAQ says the cap does not guarantee lower taxes, because millage rates and non-ad valorem assessments are set elsewhere. Estimate taxes from your purchase price and the local millage instead.
Insurance. This is the most volatile line in the payment. Landlord policies generally cost more than owner-occupied policies. Get a quote on the specific property before you finalize sizing. Ask about roof age and the wind or hurricane deductible, because both move the price.
HOA and CDD. Association dues count in full. A community development district (CDD) charge is a fixed per-parcel assessment that shows up as its own line on the county tax bill. It does not shrink if you negotiate the price down. Ask for the complete tax bill and read the non-ad valorem section.
This article does not publish Orlando averages for these lines, because they differ block by block. Your own quotes and bills are the numbers that matter.
Worked Sizing Examples in Ratios
These are modeled scenarios, not market data. They use coverage ratios only.
The pass. Picture a duplex in an established Orlando-area neighborhood with a lease close to appraised rent. Taxes are reset, insurance is quoted, and there are no CDD charges. Coverage lands near 1.25. The file clears the 1.00 floor with room to spare. At 75% to 80% LTV on a purchase, the leverage cap and the coverage test both fit. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
The near miss. Say you are buying a newer single-family home in a master-planned community with a CDD line and monthly association dues. The rent is solid, but the payment side is heavy and coverage prints around 0.95. Putting more cash down shrinks the loan and lifts the ratio to the low 1.0s. Negotiating the price down does the same. This is the file where sizing earns its keep.
The clear fail. Consider a high-priced home with an older roof and a hard insurance quote. Even at a larger down payment, coverage sits well under 1.00. Some select lenders in the network will look at coverage below 1.00, but leverage and terms are adjusted, so you would put in more cash. The honest move is often a different property.
The Levers When the Number Falls Short
Rank your options by how much each one moves the ratio.
- Larger down payment. It lowers the payment and can lift coverage. It does not erase leverage caps, credit floors, or reserve rules.
- Lower price. This shrinks the loan and also the reset tax bill.
- Defensible rent. Raise the rent used for lender review only if the appraisal supports it. An optimistic rent assumption just gets repriced.
- Interest-only structure. Interest-only periods are available through select lenders in the network, and principal drops out of the payment. Confirm whether the lender sizes on the interest-only payment or the fully amortizing one.
- A different property. Compare tax bills, association charges, insurance risk, and price. Sometimes the best fix is another listing.

Program Guardrails to Size Against
Coverage is one test. Your file has to clear the others too. These are typical ranges from select lenders in Lendmire’s wholesale network, subject to lender guidelines.
- Leverage: most purchase files land at 75% to 80% LTV on an investment property. A select high-leverage tier reaches 85% LTV with roughly a 700+ score.
- Credit: a 620 floor exists in parts of the network. Most programs want around 660. A score of 700 or better opens the strongest leverage tiers.
- Reserves: commonly around 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000.
- Loan size: up to $3,000,000 on standard programs.
- Coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted.
One structure note. No-ratio qualification is available only through select lenders, generally for borrowers who already own a primary residence.
Some property types are not offered in this network: manufactured homes (single- and double-wide), log homes, and barndominiums. Check the property type before you spend time on the numbers.
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.
Short-Term Rental Sizing
Orlando draws vacation rentals, and that tempts investors to size on nightly rates. Do not multiply a nightly rate by 30 and treat it as rent. As Class Valuation explains, the standard rent schedule was built only to estimate long-term monthly market rent.
Short-term rental income is documented through other means, such as a short-term rental analysis or hosting history. Programs for these files typically expect a higher score, around 640 or better, and about 12 months of hosting history. Purchase leverage tops out at 75% LTV.
Coverage Is Not Cash Flow
A DSCR file passes when rent used for lender review covers PITIA. That is all it measures. Vacancy, repairs, management, utilities, and capital expenses sit outside the calculation.
So a property can clear 1.25 and still lose money in a vacancy year. Size for the lender’s test, then run your own budget with those costs included. Tax treatment varies; consult a qualified professional.
The investors who do well here treat the ratio as a minimum. They want coverage with a cushion, a reserve fund, and a property they could hold through a soft stretch.
Pre-Offer Checklist
- Get the full tax bill and estimate reset taxes from your purchase price.
- Get a real insurance quote on the address.
- Pull association and CDD charges from the documents.
- Estimate appraised rent, and treat the lease as a second number.
- Run coverage at your target and at a stressed case with higher insurance and lower rent.
- Confirm the property type is eligible and that short-term plans are allowed.
Key Terms Defined
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly housing payment.
DSCR (debt service coverage ratio): monthly rent divided by PITIA, a measure of whether rent covers the payment.
LTV (loan-to-value): the loan amount as a percentage of the property’s value.
CDD (community development district): a special district whose fixed charge appears on the county tax bill, separate from HOA dues.
Non-ad valorem assessment: a charge on the tax bill that is not based on the property’s assessed value.
Seasoning: a waiting period between events, such as owning a property before refinancing it.
Frequently Asked Questions
Does an interest-only period make a rental easier to size?
It can, because principal drops out of the payment, which lifts coverage. Interest-only periods are available through select lenders in the network, but they vary by lender. Confirm whether the lender counts the interest-only payment or the fully amortizing one before you size on it.
Do my personal income and tax returns matter?
A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. Credit score, reserves, and leverage still matter, so personal finances are not irrelevant. Documentation differs from a standard owner-occupied mortgage.
What if my lease rent is higher than the appraisal?
Many programs use the lower of the two. A market-rent opinion below your lease can drop the ratio into a lower tier. Size to the appraisal number and treat the lease as upside.
Can a property under 1.00 coverage still be financed?
Select lenders in the network offer coverage below 1.00, with leverage and terms adjusted. Expect to bring more cash. Eligibility review depends on the lender, credit, reserves, and property review.
Can I count Airbnb income to hit the ratio?
Only through the short-term rental documentation a program requires, not nightly rates times 30.
