The Quick Read: In Nashville, the local permit decides whether short-term rental income counts at all. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. On STR files across the wholesale network, purchase leverage tops out at 75% LTV, cash-out at 70%, with a 640+ credit score and about 12 months of hosting history expected. Confirm the permit first. Run the coverage number second.
Key Takeaways
- Legal STR status comes before any coverage math. No permit, no lawful income to underwrite.
- STR purchase files run up to 75% LTV. Refinance and cash-out run up to 70%.
- Coverage of 1.00 is a floor for select STR programs, on both purchases and refinances. Stronger ratios open better terms.
- Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only.
- Nashville permits do not move cleanly into an LLC, so vesting has to be planned around the permit.
- Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
What Is a DSCR Loan for a Short-Term Rental?
A DSCR loan for an STR is an investor loan that looks at the property’s rental income against its full monthly obligation (principal, interest, taxes, insurance, and HOA where it applies). The borrower’s personal income is not the main test. The property’s income is.

As of Oct 1, 2026 · General Freddie Mac market benchmark, not a Lendmire loan offer. Nightly rate, occupancy, taxes, and insurance are editable estimates. 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.
For the full product picture, the complete DSCR loans guide covers the basics. This article stays on the STR layer and uses Nashville as the worked example of what derails files.
Why do STR investors reach for this product? Their traditional personal-income documentation often shows little income because of depreciation. A conventional file reads that as weak. A DSCR file reads the property.
Why Does Nashville Matter for Underwriting?
Nashville matters because the city shows the main STR risk in plain view: the permit decides whether the income counts. 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.
With that said, one point is worth stating because it changes how files get built. Metro Nashville requires a permit before a property is listed on a platform, and that permit has to be renewed each year. A permit tied to an individual is a different animal from a permit on a file owned by an entity. The NASTRA host guide is a useful trade-association read on how the permit types work.
Here’s the catch for lenders. An unpermittable property has no lawful STR income. A pro forma built on Airbnb comps is just a spreadsheet if the use isn’t allowed. Files get stuck here, not on the ratio.
Also watch the sequence. A local law firm’s summary notes that listing before you hold a permit can leave an owner ineligible to apply for a full year. Investors who test the market with a live listing first can wreck their own permit path.
How Does Underwriting Treat STR Income, Step by Step?
Underwriting treats STR income as a documented, annualized, adjusted number divided by the full monthly obligation. Peak-season income is not what gets used. The steps below are how files typically move across the network.
1. Confirm legal status. The lender needs to see that the use is lawful. For permit markets, that means the permit or a clear path to one.
2. Pick the income method. On a property with history, platform or property-manager statements and bank deposits carry the most weight. An appraiser’s STR income analysis is another route. Market data from tools like AirDNA is used on many purchases, and some programs want it alongside other support.
3. Annualize and adjust. Lenders look at the full year, not the best quarter. Seasonality and vacancy get priced in. Adjustment methods differ by lender, which is why two programs can produce different coverage numbers on the same property.
4. Divide by PITIA. Qualifying monthly income divided by principal, interest, taxes, insurance, and HOA dues. That’s the coverage ratio.
5. Layer in the file. Credit, reserves, entity documents, insurance, and the appraisal all get reviewed. The 1007 is the rent schedule form, and the 1025 is the small residential income appraisal for 2-4 units. Those are form names only.
The wholesale network sees many lenders’ versions of this process. Most programs run the steps above. The details, such as which income source leads and how big the adjustment is, differ by program. Some lenders in the network only accept market data on purchases. Others want statements once the property has operated for a year.
What Do the Program Numbers Look Like?
STR files run tighter than long-term rental files. The ranges below describe typical guidance across select lenders in the network, subject to lender guidelines and not a commitment to lend.
| Factor | STR Purchase | STR Refinance / Cash-Out |
|---|---|---|
| Max LTV | Up to 75% | Up to 70% |
| Min credit score | 640 | 640 |
| Coverage floor | 1.00 | 1.00 |
| Hosting history | About 12 months expected | About 12 months expected |
Loan sizes run up to $3,000,000 on standard programs. Reserves vary by lender, leverage, loan size, and transaction type. Around six months of PITIA is common, and larger loans typically step up from there.
A larger down payment lowers the monthly obligation and can lift the ratio. It never erases the leverage cap, the credit floor, the reserve rule, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence. Neither is the default path on an STR file.
Where Does the General Rule Break?
The general rule is simple: lawful, documented income divided by PITIA. These edge cases are where it breaks, and Nashville supplies the sharpest ones.
Permit held by a person, buyer is an LLC. Metro Codes says an owner-occupied permit requires a natural person living at the property. LLCs, corporations, trusts, and partnerships are ineligible for that type. Ownership changes cancel the permit, including a move from a person to a trust or LLC. So vesting and closing structure have to be planned around the permit. LLC vesting is subject to lender program eligibility, and the permit rules are separate from the loan.
Grandfathered permits. Metro’s permit types page says new not-owner-occupied permits are not allowed in AR2A, R, RS, or RM zoned properties. Existing holders there may renew, but those permits are not transferable on a sale. A buyer of a permitted home can lose the STR right at transfer. Picture an investor who underwrites a purchase on the seller’s trailing statements. If the permit doesn’t carry over, those statements describe income the buyer can’t legally earn.
No operating history. On a purchase of a property that hasn’t operated, projections lead. Market data and conservative estimates usually do the work. Programs that expect about 12 months of hosting history are looking at the borrower’s experience as well as the property’s.
Heavy seasonality. An annualized 1.15x can hide thin months. Say most income lands in a few summer months. A snapshot taken at the peak flatters the file, and some lenders stress for the off-season. Reserves matter more here than the headline ratio.
Blended buildings. A building with some annual leases and some nightly units is underwritten on the blended rent roll.
Program availability. Not every lender in the DSCR space takes STR income. Some will only underwrite the property as a long-term rental. That’s one reason brokers shop the file across several programs instead of one.
Rule changes after closing. The loan stays in place if local rules tighten. The cash flow can take the hit. Reserves are the buffer.
What Are the Structure Options?
The spine of the network is the 30-year fixed. Interest-only periods and extended terms such as 40-year are available through select lenders. ARM structures exist for investors who want them. Above $2,500,000, the network generally holds to 30-year fixed structures.
Interest-only can help an STR file on the coverage number because the monthly obligation drops during the interest-only period. It also changes the refinance plan later. Investors should think about what happens when the period ends.
Not offered in the network: manufactured homes (single- and double-wide), log homes, and barndominiums. A cabin-style STR that is a log home falls outside these programs. Check construction type before the offer, not after.
If a file already owns the property and wants equity out, the refinance side runs up to 70% on STR collateral, with the same 1.00 floor on refinances. For a related topic, see how a lender defines what counts as short-term rental income.
Does Clearing 1.00 Mean the Property Cash Flows?
No. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, platform fees, cleaning, and capex all sit outside the calculation.
Market surveys report STR operating expense ratios commonly running between 45% and 65% of gross revenue, well above long-term rentals. A property can clear 1.00 on the lender’s number and still lose money on the investor’s books.
DSCR vs. conventional financing
There are two common ways to finance an investment property in this market, 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.
Run your own version before the offer. Use a haircut on projected revenue, a full expense load, and a downside month. If the property only works at peak occupancy, the lender’s number is the least of the problems.
Here’s where the experience shows up on files. STR deals tend to look fine on gross revenue and fall apart when the investor lists real expenses. The files that move cleanly usually have the permit, the insurance quote, the entity documents, and the income support all in one folder before submission. Nashville’s application itself asks for proof of insurance with liability limits of at least $1 million per occurrence, and entity-owned properties must show documents linking the entity to the individual. That paperwork overlaps with what a lender wants to see, so build it once.
Key Terms Defined
DSCR: The ratio of qualifying monthly rental income to the full monthly housing obligation.
PITIA: Principal, interest, taxes, insurance, and HOA dues where they apply.
Annualized income: Income averaged across a full year rather than taken from the best months.
1007 rent schedule: An appraisal form that estimates market rent on a rental property.
1025 appraisal: A small residential income property appraisal used on 2-4 unit properties.
Seasoning: The ownership period a lender expects before allowing a cash-out refinance. About six months is the common expectation across most of the network.
Haircut: A reduction a lender applies to gross STR income before dividing by PITIA.
What Should the Investor Do in Practice?
Work in this order. Each step removes a way for the file to fail.
1. Check zoning and permit eligibility before the offer. Not after contract.
2. Decide the vesting structure with the permit in mind. Talk to a local attorney about how an LLC fits.
3. Gather income evidence. Statements and deposits if the property has history. Market data and a rent analysis if it doesn’t.
4. Model coverage with a haircut and real expenses.
5. Confirm credit and leverage. A 640+ score, up to 75% on a purchase, up to 70% on a refinance.
6. Document reserves. Reserve rules vary by lender, leverage, and loan size.
7. Pick a program that takes STR income. That’s where a broker adds value, because the programs differ.
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.
Investors weighing an LLC purchase can also consider whether holding a luxury short-term rental in an LLC fits their goals.

Frequently Asked Questions
Can I use a DSCR loan on a Nashville short-term rental?
Yes, if the property can lawfully operate as an STR and the file fits a program that takes STR income. The permit comes first. Then the file runs on property income, credit of 640+, and leverage up to 75% on a purchase, subject to lender guidelines.
What coverage ratio do I need on an STR?
Select STR programs start at 1.00 on both purchases and refinances. Stronger ratios usually open better pricing and leverage.
Does an STR need 12 months of history?
About 12 months of hosting history is the common expectation on STR files. Newly purchased properties without operating history typically lean on market data and conservative projections. Requirements differ by program.
Can I put my Nashville STR permit into an LLC?
Not cleanly. Metro Codes says ownership changes cancel the permit, and owner-occupied permits exclude entities. Plan the vesting before closing, and note that LLC lending is subject to lender program eligibility.
What leverage is available on an STR cash-out?
STR cash-out and refinance files run up to 70% LTV, and a standard long-term rental cash-out tops out around 75%. About six months of seasoning is the common expectation. Reserves vary by file. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
