The Quick Read: Sub-1.0 coverage with reserves keeps a real rent test in the file and rewards documented performance. No-ratio drops the rent test and leans on credit, equity, and housing history instead. Both run through select wholesale programs, with LTV and terms adjusting, subject to underwriting. The right pick depends on how well your income documents and how much cash you can leave parked.
- Sub-1.0: Coverage below 1.00 is a real path through select lenders in the network, up to $2,000,000. LTV and terms adjust, subject to underwriting.
- No-ratio: Available through select wholesale programs up to $2,000,000, with a seven-year clean housing history and 0x30x24, subject to underwriting.
- STR income: The short-term-rental income path needs coverage of 1.00 or higher and is not offered on the no-ratio path.
- Reserves: Most files carry 6 months of PITIA on the subject property, and 12 months for first-time investors.
- Above $2,000,000: Neither option is on the table. The standard ladder applies, and it wants coverage of 1.00 or higher.
The Honest Answer on Who Each Option Is For
Sub-1.0 with reserves suits the operator whose rental income is real and documented but falls a bit short of the payment. The lender still reads your numbers, and your cash cushion covers the gap. No-ratio suits the operator whose income is hard to document, such as a seasonal property, a fresh conversion, or a luxury home still ramping up. The lender sets the rent test aside and underwrites the borrower and the equity.

As of Oct 15, 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.
Here is the catch that most luxury operators miss. Across the wholesale network, short-term-rental underwriting runs at 1.00 coverage or better and is not paired with no-ratio. So if your STR income falls short of 1.00, you are usually choosing between a rent-based sub-1.0 file and a no-ratio file. You are not choosing between two ways to use your Airbnb numbers.
Neither option rescues a weak property. Both are tools for a good asset with an uneven income picture.
Side-by-Side
The table below shows network parameters where Lendmire’s guidelines set them. Where a cell says “varies,” it reflects how published industry norms differ from lender to lender. Every figure is subject to underwriting, and nothing here is a commitment to lend.
| Factor | Sub-1.0 With Reserves | No-Ratio |
|---|---|---|
| Review basis | Ratio runs; shortfall is offset | Credit, equity, housing history |
| Rent evidence | Required (rent schedule or STR data) | Not the deciding factor |
| STR income credit | STR basis needs 1.00 or higher | Not on the STR path |
| Loan size | Select programs, to $2,000,000; LTV and terms adjust | Select programs, to $2,000,000 |
| Leverage | Reduced; LTV and terms adjust | Varies; usually reduced |
| Credit and history | 660 floor; 700+ in higher bands | Seven-year clean housing, 0x30x24 |
| Reserves | 6 months PITIA; 12 if first-time | Same base; some programs ask more |
| Entity vesting | Welcome; no layered entities | Varies; confirm per program |
| Property types | 1-4 units, condos, condotels | Varies; confirm per program |
Key Terms Defined
DSCR (debt service coverage ratio) is the property’s monthly rent divided by its monthly debt payment. Above 1.00, the rent covers the payment.
PITIA is principal, interest, taxes, insurance, and association dues. Scotsman Guide describes DSCR the same way, with PITIA as the denominator.
Sub-1.0 coverage means the ratio is calculated and comes in under 1.00. The lender accepts the shortfall because other strengths offset it.
No-ratio means the rent test is not the qualifying factor. Usage varies by lender, so confirm whether a program skips the ratio entirely or calculates it without relying on it.
Reserves are liquid assets, verified on recent statements, that the lender expects you to hold after closing. They are the cushion that carries the loan if income dips.
ITIA is the interest-only version of PITIA, with principal removed from the payment.
Why Luxury STRs Land Under 1.00
High-priced short-term rentals often miss 1.00 because the payment grows faster than the nightly income. A larger balance means a larger payment. Taxes, insurance, and association dues on premium properties add weight to the denominator.
The numerator also gets trimmed. In the network, short-term-rental income is counted at 80% of gross. It comes from twelve months of operating history on a refinance, or from the appraisal’s short-term-rent analysis on a purchase. To clear 1.00 on that basis, your gross has to run roughly 1.25 times the full payment. (That is a stiff bar for a seasonal property.)
Seasonality does the rest. A strong trailing year can still hide a few thin months. The lender reviews the file on the annual picture. Your bank account lives through the monthly one.
Short-term rental rules can vary by city, county, HOA, and property type. Investors should confirm local rules before relying on projected rental income. Lenders also ask for documented municipal permission on each property, which is never assumed for a city or state.
When Sub-1.0 With Reserves Is the Better Fit
Choose sub-1.0 when your rent picture is documented and close to the line. This path keeps the rent test in the file, so strong operating numbers still help you. Across our wholesale network, coverage just under 1.00 is a real path through select lenders, up to $2,000,000, with LTV and terms adjusting, subject to underwriting. Scotsman Guide reports a similar pattern: some non-QM lenders will lend below 1.0 when other assets offset the shortfall, and terms adjust accordingly.
Interest-only helps here. The network offers a 120-month interest-only period on 30- and 40-year terms, up to 75% LTV, qualified on ITIA. Removing principal from the qualifying payment lifts the ratio, though your balance does not shrink during that period. For a file below 1.00, LTV and terms adjust, subject to underwriting, and the outcome follows a full review of property, leverage, and credit.
Picture an operator buying a $1.8 million coastal home as an investment property. Credit sits above 720, and the appraisal’s short-term-rent analysis lands the file near 0.9x. A full-coverage file at that size band caps at 75% LTV on an investment-property purchase. A sub-1.0 file sits below that ceiling. The operator brings more cash to closing, keeps the rent test, and holds the standard reserve cushion. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Sub-1.0 fits best when:
- Your coverage is close to 1.00 and you can document why.
- You have at least twelve months of income history on a property you own.
- You would rather put cash into equity than hand the lender a no-ratio file.
- You plan to refinance once seasoning pushes the ratio higher.
When No-Ratio Is the Better Fit
No-ratio earns its place when the rent test is the obstacle. Through a handful of lenders in the network, no-ratio files go up to $2,000,000, subject to underwriting. The program envelope is roughly 75% LTV on a purchase, 70% on a rate-and-term refinance, and 65% on a cash-out, with a 640 minimum credit score, all subject to underwriting. It also asks for a seven-year clean housing history and 0x30x24, which means no 30-day late payments in the last 24 months. It is reviewed on the borrower’s credit, the equity in the deal, and reserves.
This path fits a property with no operating history, a recent conversion, or a home bought ahead of a renovation. It also fits an operator who expects appreciation to carry the deal while income ramps up. A luxury house that will take a full season to stabilize is a classic case.
The tradeoffs are real. The short-term-rental income path is not available on no-ratio, so your STR numbers do not help the file. No minimum ratio is published for it, and the program envelope sets the leverage and terms. Industry norms generally show lower leverage and heavier cash expectations for no-ratio than for standard coverage. Some programs also restrict who can use it, such as first-time investors or vacant properties, so confirm the envelope before you price the deal.
Sizing Reserves Against Your Own Off-Season
Reserves are a design choice, not just a box to check. The network minimum is 6 months of PITIA on the subject property, or 12 months for first-time investors. On interest-only files, the count runs on ITIA. No extra reserves are required for other financed properties, and cash-out proceeds never satisfy the requirement.
The minimum is the lender’s number. Your number should come from a trough test. Run it with ratios, since the payment is your unit of measure:
1. Find your weakest stretch of months and estimate coverage in those months. Say it runs 0.6x.
2. Subtract from 1.00. The shortfall is 0.4 of a payment per month.
3. Multiply by the months in the trough. Four months at 0.4 comes to 1.6 payments of cash you must supply.
4. Add a buffer for a slow year, repairs, and a vacancy between bookings.
On those assumptions, the 6-month minimum covers the trough with room to spare. A deeper trough or a larger property may not. Peak months then rebuild the cushion, so treat peak income as reserve replenishment before you treat it as distributable cash.
There is also an opportunity cost. Cash held as reserves is cash not working elsewhere. Sub-1.0 files ask you to hold the cushion and bring more equity. No-ratio files ask you to prove stability through credit and housing history. Neither is free, and the cheaper one depends on what your idle cash would otherwise earn.
Think of it this way: a sub-1.0 file has a thin rent test and a thick reserve account, while a no-ratio file has no rent test and a thicker borrower profile.
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 Stays the Same Either Way
Both paths are business-purpose investor loans on non-owner-occupied property. They are reviewed differently from a standard owner-occupied mortgage. Federal regulation exempts credit extended primarily for a business or commercial purpose from the consumer lending rule. The eCFR text adds that credit extended to someone other than a natural person is also exempt.
That exemption does not remove the lender’s own credit review. Credit, equity, reserves, and experience are all read on both paths. A no-ratio file is still underwritten.
Entity vesting is welcome on the standard program, with no layered entities, subject to lender program eligibility. Whether a given no-ratio program accepts an LLC varies, so ask early. Trust borrowers need extra care.
Documents overlap heavily. Expect an appraisal, a credit authorization, recent asset statements, insurance, and entity papers. The sub-1.0 file adds rent evidence. The no-ratio file drops it.
Condos and condotels are common in luxury resort markets. Condotels carry tighter limits, reaching 75% on a purchase and 65% on a refinance, up to $1,500,000, with $250,000 cash-in-hand. Non-warrantable condos top out at 75% and $1,500,000. Pooling arrangements change how income is documented, so flag them at the start.
What Moves a Borderline File
On a sub-1.0 file, the strongest evidence is operator statements and platform history that show the income pattern. Trailing twelve-month records from the platform or a property manager carry the most weight. The appraisal’s short-term-rent analysis fills the gap on a purchase.
On a no-ratio file, the borrower’s mortgage payment record carries the weight. Seven clean years of housing history and 0x30x24 are the entry ticket. Strong credit, meaningful equity, and a liquid reserve account do the rest.
Experience matters on the STR income path. That path asks for experienced investors, meaning twelve months owning income property in the last thirty-six. Credit minimums step up with size, from a 660 floor to 700 and above in the higher bands.
When Neither Fits
Sometimes the honest answer is to restructure. Above $2,000,000, sub-1.0 and no-ratio drop away. The standard size ladder applies, with 75% LTV on an investment-property purchase to $3,000,000, then 65% to $4,000,000. Above that, 60% applies on review, and every request there is reviewed case by case before submission. Those tiers want coverage of 1.00 or higher. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
You have a few options when the numbers will not stretch:
- Bring a smaller loan to the same property by adding equity.
- Wait for operating history to build, then revisit on a refinance.
- Use interest-only to lift qualifying coverage if the file fits the 75% ceiling.
- Choose a property with a stronger rent-to-price relationship.
A coverage shortfall is not a documentation problem. It is a property problem.
The Balanced Verdict
Choose sub-1.0 with reserves if you can document the income, you sit near the line, and you would rather hold cash than give up the rent test. Choose no-ratio if the income cannot be documented yet, your housing history is spotless, and you accept that your STR numbers will not help the file. Choose neither if the loan runs past $2,000,000 or the property cannot cover itself at any reasonable seasoning.
For most luxury operators with a year of clean statements, sub-1.0 is the more natural fit. It uses the evidence you already have. The no-ratio path is the tool for the property that has not yet earned its numbers. Read the complete DSCR loans guide for the full program picture.
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
Is no-ratio the same as sub-1.0?
No. Sub-1.0 calculates the ratio, finds it short, and accepts the gap because other strengths offset it, with LTV and terms adjusting, subject to underwriting. No-ratio means the rent test is not the qualifying factor. Through select wholesale programs, no-ratio files reach $2,000,000, subject to underwriting and the program’s credit and housing-history envelope.
Do reserves replace the rent test?
Not on a sub-1.0 file. The ratio still runs, and reserves are the cushion that supports the shortfall. Most files carry 6 months of PITIA on the subject property, and 12 months for first-time investors, subject to underwriting.
Can I use my STR income on a no-ratio loan?
No. The short-term-rental income path requires coverage of 1.00 or higher and is not offered on the no-ratio path. It is also limited to experienced investors and to loans up to $2,000,000.
Can an LLC borrow on either path?
Often, yes. Whether a specific no-ratio program accepts an LLC varies, so confirm it before you price the deal.
What if my loan is above $2,000,000?
Sub-1.0, no-ratio, and short-term-rental files stop at $2,000,000. Above that, the standard ladder applies, with two appraisals above $2,000,000 and coverage of 1.00 or higher. Above $4,000,000, every request is reviewed case by case before submission, on purchase or rate-and-term only.
