The Quick Read: Start by asking which income the lender will count after the property changes use, because that one answer drives coverage, leverage, and the rest of the file. The ratio formula stays the same in both directions, but the rent input changes from booking history or a projection to a lease or an appraiser’s market-rent figure. Most of the other questions follow from that one.
- Ask which income source governs after conversion: the lease, the appraiser’s market rent, or documented STR history.
- Ask whether the file is treated as a short-term or long-term rental for leverage, since the tiers differ.
- Ask whether STR income carries a haircut or expense factor, and whether that factor is a minimum.
- Ask about seasoning, prepayment terms, and whether insurance has to match the new use.
- Run the same property on both income bases before you change a listing or sign a lease.
The brokerage side of this is simple to describe and easy to get wrong. A conversion is not a rename. The property is the same, the loan file is not. This piece lays out what to ask, why each answer matters, and what a clean reply sounds like. For the program basics behind it, see Lendmire’s complete DSCR loans guide.

Key Terms Defined
DSCR (debt service coverage ratio): qualifying monthly rent divided by the full monthly housing payment.
PITIA: principal, interest, taxes, insurance, and association dues, which together form the denominator.
Market rent: the monthly rent an appraiser estimates for the property as a long-term rental.
Hosting history: the documented record of bookings and income on a short-term rental, which lenders use to judge STR income.
Haircut (expense factor): a percentage lenders subtract from gross STR income before testing coverage.
Seasoning: the minimum time you must own the property, or hold a given use, before a refinance option opens.
Qualifying payment: the payment structure the lender uses in the denominator, which can differ from what you actually pay.
Which Direction Are You Converting?
The direction decides which documents carry the file. STR to LTR leans on a lease and market rent. LTR to STR has no booking record yet, so many lenders fall back on long-term market rent until bookings exist.
| Situation | Income basis likely reviewed | First question to ask |
|---|---|---|
| STR to LTR | Signed lease or market rent | Which rent do you count after the lease starts? |
| LTR to STR | Market rent, then hosting history | How long must I host before STR income counts? |
| Mid-term or furnished monthly stays | Depends on the lender’s classification | Is this treated as STR or LTR? |
| Paused or partial-year STR | Partial history or market rent | How do you treat gaps in bookings? |
Select lenders in the network differ on this. Some qualify an STR only as if it were a long-term rental. Others accept twelve months of documented history. A few will consider a market-data projection. That spread is the reason the question comes first. Lendmire’s piece How to Qualify an LTR Conversion for a Short-Term Rental DSCR Loan covers the LTR-to-STR side in more depth.
The Income Questions
The income questions decide whether the ratio is even calculable. Ask them in order, and get the answers in writing before you order an appraisal.
1. Which income source will you use if I convert? A good answer names one: the lease, the Form 1007 or 1025 rent, or STR history. A vague answer means the lender decides late, and late decisions are where files get re-underwritten on long-term comps.
2. Is there a haircut on STR income, and is it a floor? Expense factors are not fixed rules. Lenders apply them differently, and some experienced hosts get none. Ask for the number the lender uses, then run it yourself.
3. How many months of history do you need, and what proves it? Platform exports, manager statements, and bank deposits that reconcile. Across the network, about 12 months of host experience is the common expectation on short-term-rental files.
4. Does purchase treatment differ from refinance treatment? It can. A refinance may lean on leases or traditional personal-income documentation alongside the appraisal rent. A purchase usually leans on the appraisal and any history.
5. What happens if the appraiser’s rent comes in below the lease? Lenders commonly credit the lower of the two. Ask whether that is the rule on this program.
What the Appraisal Rent Schedule Does (and Doesn’t) Measure
The rent schedule is a long-term-rent tool. It does not measure Airbnb income. Fannie Mae’s appraiser update describes Form 1007 as the Single-Family Comparable Rent Schedule, which documents estimated monthly market rent on a single-family investment property. DSCR loans are not agency products, so this is context for the form name only. For two-to-four unit properties, the equivalent is Form 1025, the Small Residential Income Property report.
McKissock notes the form estimates monthly market rent for single-family or condo investment properties, and that how income is ultimately used falls under the lender’s scope. On a refinance, it points out the form is used alongside leases or traditional personal-income documentation. Class Valuation goes further and argues the form cannot support short-term-rental appraisals because it was built only to estimate long-term monthly rent.
What that means in a file: on an STR-to-LTR conversion, the appraiser’s rent is often the number that sets coverage. On an LTR-to-STR move, it is often the fallback until bookings exist. Either way, the 1007 is never proof of nightly income.
Legality and HOA Questions (Old Use and New Use)
Ask about both uses. 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. Then ask the lender two things: does it review those restrictions at the address level, and does a change in permitted use affect eligibility?
On a conversion to STR, an HOA that limits rental terms can end the plan before the loan matters. On a conversion to LTR, check whether the lease term you plan fits the building’s rules. Condo and HOA questionnaire completeness also matters here, since dues sit in the denominator and reduce coverage.
The Loan-Term Questions Most Investors Skip
Income and legality get the attention. Loan terms are where conversions quietly change the deal. Ask each of these directly.
What leverage tier applies to this use? Across the network, short-term-rental purchases go up to 75% LTV on the strongest files, while STR cash-out and refinance files top out around 70%. A standard long-term rental refinance can reach about 75% LTV on cash-out. Converting use can move you between those tiers. Ask which one the lender applies, and ask in writing. A stated maximum is a ceiling, not an offer, since credit, property, and loan purpose can lower it. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
What is the minimum coverage for each case? On STR files, coverage floors typically sit at 1.00 on both purchases and refinances in the network. For long-term rentals, 1.00 is where select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. No-ratio structures are available only through select lenders, generally for borrowers who already own a primary residence. Ask which path your file is on.
What credit score applies? STR files typically want about a 640 minimum score. Most long-term programs want around 660, with a 620 floor in parts of the network and 700-plus unlocking the strongest tiers. A conversion can move you across a score line.
Which payment structure qualifies me? The spine of the network is the 30-year fixed. Extended terms, including 40-year, and interest-only periods are available through select lenders. ARM structures also exist. The qualifying payment can differ by structure, so ask which payment sits in the denominator.
Is there a seasoning or hosting-history rule? Cash-out files commonly expect about 6 months of seasoning. Short-term-rental files expect roughly 12 months of host experience. Ask whether the clock runs from purchase date or conversion date.
What are the prepayment terms, and do they change on conversion? Ask for the structure in writing. Also ask about the loan you are replacing, since a prepayment charge on the existing loan changes the math on a refinance.
What reserves apply? Reserves vary by lender, leverage, loan size, and transaction type. Around 6 months of PITIA is common. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived, and larger loans typically step up to about 9 months. Say it back to the lender as a range, then get the actual number for your file.
Does insurance have to match the use? A policy written for a long-term rental may not cover STR operation. Insurance sits in PITIA, so a higher STR premium reduces coverage.
Loan sizes run up to $3,000,000 on standard programs (smaller balances available through select lenders), and above $2,500,000 the network generally holds to 30-year fixed structures. All of this is subject to lender guidelines, and each file is underwritten individually.
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.
A Worked Example: Same Property, Two Income Bases
Take one property and test it twice. Illustrative inputs, not program terms: say a lender applies a 20% factor to STR income, and STR gross income runs about 1.6 times the monthly payment. After the haircut, STR coverage lands near 1.28x. Now swap in the appraiser’s long-term market rent, which comes in at about 1.05 times the payment. Coverage on the LTR basis is 1.05x.
Both numbers clear 1.00. They are not the same deal. The STR basis may support better pricing and more room on a refinance. The LTR basis sits close to the line, where a slightly higher insurance quote or HOA increase can push it under. That gap is the reason to run both before you act.
One more caution. Clearing 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation.
If the Ratio Comes Up Short
When the converted rent produces a lower number, work the fixes in order of cost.
1. Check the income basis. Ask whether another documented source, such as a lease paired with a lease addendum or a stronger appraisal rent, fits the program.
2. Check the denominator. Insurance quotes and HOA dues are the lines most often corrected.
3. Lower the balance. A larger down payment lowers the payment and can lift coverage. It never erases leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
4. Ask about structure. Interest-only periods and extended terms are available through select lenders and change the qualifying payment.
5. Ask about the sub-1.00 path. It is available through select lenders in the network, with leverage and terms adjusted.
Lendmire’s piece Projected STR Income vs Rental History for a Long-Term-to-Airbnb Conversion walks through which basis tends to govern when both exist.
Conversion Paperwork Checklist
Gather this before you ask for a quote, not after.
- Signed lease with start date, term, and rent amount.
- Proof of deposit and first rent payment, if the lender asks.
- Deactivated or paused listings, with screenshots or confirmations.
- Platform exports and manager statements for any STR history you are relying on.
- Updated insurance that reflects the new use.
- Entity documents, if the property is held in an LLC, subject to lender program eligibility.
- HOA or municipal confirmations on the permitted use.
- Appraisal access arranged with the tenant or host calendar in mind.
Appraisal access is a quiet friction point. A lease tenant who will not allow entry, or a guest calendar that blocks the visit, delays the schedule and can stall the file.
Red-Flag Answers and Getting It in Writing
Some replies tell you to walk before you pay for an appraisal. “We will see what the appraiser says” with no income basis named. A leverage figure with no mention of use type. A coverage floor that moves depending on who you ask. Not every lender lends on short-term rentals at all, so a polite refusal late in the process is a real outcome, and asking early avoids it.
Put three answers in writing: the income source, the leverage tier for your use, and the prepayment structure. Those are the three that change most often between first call and file review. Ask the questions before the appraisal and before you change a listing or sign a lease. Changing the use first and asking second leaves you with a property that fits no program cleanly.
If you are buying or refinancing a rental property and want to see how the numbers work, Lendmire can help you compare DSCR loan options based on the property income, credit profile, leverage, and investor goals.
Frequently Asked Questions
Does STR income still count after I convert to a long-term rental?
Usually not as the primary basis. Once a lease is in place, most lenders look to the lease or the appraiser’s market rent. Some may consider documented history if the conversion is partial, but get that confirmed in writing.
Should I deactivate my listing before applying?
Ask first. If the lender plans to use STR history, a dead listing can complicate that. If it plans to use the lease, a live listing next to a signed lease creates confusion about which use governs the file.
Do mid-term or furnished monthly rentals count as STR or LTR?
It depends on how the lender classifies them, which is why the question belongs in your first call. The classification changes the leverage tier and the income basis, so do not assume.
What should I ask first?
Which income source the lender uses after conversion. Every other answer, from leverage to coverage floors, follows from that one.
Is 1.00 coverage enough to get approved?
No. Clearing 1.00 does not establish approval, profitability, or reserves. Approval depends on lender guidelines, credit, property review, and the full file.
