The Quick Read: A sub-1.0 path still measures rent against the full monthly payment but accepts a shortfall in exchange for lower leverage and stronger credit, while a no-ratio path skips the rent test and leans on credit and equity, and both lean harder on reserves, which are liquid funds you hold after closing. Both run through select lenders in the network, with leverage and terms adjusted. The no-ratio path is generally for borrowers who already own a primary residence.
- 1.00 coverage is where many select programs start. It is a floor for those programs, not a rule for every lender.
- Sub-1.0 files still calculate the ratio. No-ratio files never calculate it.
- No-ratio files run to 75% LTV on a purchase, 70% on a rate-and-term refinance and 65% on a cash-out, with a 640 minimum score.
- Reserves commonly run about 6 months of PITIA, and they usually matter more when the rent is weak.
- Clearing 1.00 does not mean the property cash flows. Repairs, vacancy and management sit outside the math.
Key Terms Defined
DSCR is the debt service coverage ratio: the property’s monthly rent divided by its full monthly housing obligation.
PITIA is principal, interest, taxes, insurance and association dues, the full payment the rent is measured against.
Floor is the lowest coverage ratio a given program will accept on a standard file.
Sub-1.0 means rent covers less than the full payment, so the ratio lands under 1.00.
No-ratio means the lender does not use the property’s rent-to-payment ratio to qualify the file.
Reserves are documented liquid assets you still hold after closing, counted in months of PITIA.
LTV is loan-to-value: the loan amount as a percentage of the property’s value.
Seasoning is the waiting period a lender wants before it will count certain funds or events, such as how long you have owned a property before a cash-out.

What Is a DSCR Floor, and Why Do Lenders Set One?
Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
A floor is the minimum coverage a program accepts on a standard file. At 1.00, rent equals the payment. Many select programs start there, and stronger ratios tend to open better pricing and leverage.
Lenders set floors because rent is the first signal that a property can carry itself. A ratio under 1.00 means you would feed the property out of pocket every month. Floors differ across lenders. Across the programs in a wholesale network, you see wide spread in how much coverage each one wants and what it asks for when coverage falls short.
When the rent test is relaxed or dropped, something else has to carry the file. That something is usually a mix of lower leverage, stronger credit and more cash held back. The complete DSCR loans guide covers the baseline mechanics. The rest of this piece covers what changes at the edges.
How Does Underwriting Treat the Ratio, Step by Step?
Underwriting runs in a fixed order, and the ratio only decides the branch you land on.
1. The appraisal sets the rent, not you. For a single-family home or one-unit condo, the appraiser uses the single-family comparable rent schedule, known as Form 1007. Two-to-four-unit properties use the companion operating income form, Form 1025. Only the form names borrow from the agency world. The loan rules do not.
2. The lender calculates the ratio. Monthly rent goes on top and PITIA goes on the bottom. Tax and insurance estimates move the result, so a higher insurance quote can pull a borderline file under 1.00.
3. The file branches. At or above the program floor, the ratio qualifies the file together with credit, LTV and reserves. Below it, the deal works to a sub-1.0 path or a no-ratio path.
4. Reserves are verified. The lender documents your post-closing liquid assets, typically from recent account statements.
5. Everything else still runs. Your credit is pulled. The entity vesting and the appraisal are reviewed too.
One caution applies at every step. A quote built on an assumed rent is only an estimate until the appraisal returns the rent figure.
How a Sub-1.0 Loan Works
On a sub-1.0 file, the ratio is calculated, shown on the file and accepted as short. This path is available through select lenders in the network, with leverage and terms adjusted.
The lender is not ignoring the shortfall. It is pricing it. You typically see lower leverage than the 75%-80% LTV common on a purchase of an investment property. You also see a stronger credit expectation, more reserves and tighter terms.
Picture a rental in a high-price market where insurance and taxes have climbed. Rent that once covered the payment now falls a little short. The property is sound, and the tenant pays on time. A sub-1.0 path exists for exactly that gap, and the price of using it is more cash in the deal.
How a No-Ratio Loan Works
A no-ratio loan never uses the property’s rent-to-payment ratio. It is available only through select lenders, generally for borrowers who already own a primary residence. Qualification rests on credit and equity, not on a rent-coverage calculation.
The envelope is narrower than a standard DSCR file:
- Purchase: up to 75% LTV.
- Rate-and-term refinance: up to 70% LTV.
- Cash-out refinance: up to 65% LTV.
- Credit: a minimum score of 640.
- Not eligible: vacant properties, first-time homebuyers, and files with one or no credit score. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Compare that cash-out figure with the 75% ceiling on a standard rental cash-out. The 10-point drop is the cost of dropping the rent test. A no-ratio file still gets a credit pull, an appraisal and a reserve check. Reserves and credit often matter more here, not less.
Standard vs. Sub-1.0 vs. No-Ratio at a Glance
The three paths differ in what is measured and what carries the file.
| Factor | At or above floor | Sub-1.0 | No-ratio |
|---|---|---|---|
| Ratio calculated | Yes | Yes, shortfall accepted | No |
| What carries the file | Coverage, credit, LTV | Credit, equity, reserves | Credit and equity |
| Leverage | 75%-80% on purchase, typical | Adjusted lower | 75% on purchase, at most |
| Reserves | About 6 months | Commonly higher end | Commonly higher end |
| Best fit | Rent covers payment | Rent falls just short | Owner of a primary home |
The most common mix-up is treating sub-1.0 and no-ratio as one product with a moving floor. They are different paths. Sub-1.0 grades a shortfall. No-ratio sets the ratio aside.
Reserve Rules: How Many Months, and What Counts?
Reserves commonly run about 6 months of PITIA, and the number moves with leverage, loan size and transaction type. Lenders hold them as a cushion against vacancy and a gap in rent. You count them after closing, so the money for your down payment and closing costs does not double as reserves.
| Situation | Typical reserve posture |
|---|---|
| Most purchase and cash-out files | About 6 months of PITIA |
| Conservative rate-and-term, modest leverage, under $1,500,000 | Can be waived on some programs |
| Loans above $1,500,000 | Typically about 9 months |
| Sub-1.0 or no-ratio files | Commonly the higher end; varies by lender |
Three details trip people up. First, reserves are documented with account statements, and recent deposits that are not explained can stall a file. Second, which asset types count, and at what value, is lender-specific, so confirm before you assume a brokerage or retirement balance counts in full. Third, programs differ on whether cash-out proceeds from the subject property can count toward reserves.
Reserves also stack. If you own several financed rentals, each new file looks at what you still hold after closing, not what you held yesterday.
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 Bridge Example: Rent, Gap and Months of Runway
Run the numbers this way, using modeled ratios and not program terms. Assume rent covers nine-tenths of PITIA, a 0.90x ratio. The monthly gap is one-tenth of the payment. Six months of PITIA held in reserve then equals 60 months of that gap.
Now assume a weaker deal where rent covers only half the payment. The gap is half the payment, and six months of PITIA equals 12 months of gap. The reserve requirement did not shrink because the gap grew, and it tracks the payment, not the shortfall. A sensible buffer sits above the minimum, because a lender’s requirement is not a plan for how long you can carry a loss. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Where the General Rule Breaks
Short-term rentals. Form 1007 is built on comparable monthly leases, not nightly rates, so documenting short-term income is lender-specific. Short-term rental purchases top out at 75% LTV. Refinances run around 70%, and cash-out on short-term rental collateral also runs 70%. Expect a 640 or better score and about 12 months of hosting history. The coverage floor is 1.00 on purchases and refinances. 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. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Rent basis. Lenders may use the lower of lease rent and market rent.
Cash-out. Cash-out tops out around 75% LTV across most of the network on a standard rental, with about 6 months of seasoning as the common expectation. Lendmire’s piece Sub-1.0 DSCR and No-Ratio Floors on a DSCR Cash-Out Refinance covers that branch. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Property types. Manufactured homes (single- and double-wide), log homes and barndominiums are not offered in the network’s DSCR programs, on any path.
Large loans. Standard programs run up to $3,000,000. Above $2,500,000 the network generally holds to 30-year fixed structures, and reserves step up.
Loan purpose. 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. The federal exemption for business-purpose credit, with its text on Cornell Law School’s Legal Information Institute, turns on what the loan proceeds are for. If the proceeds go to a consumer purpose, the loan can still be a consumer loan even when a rental secures it.
Which Path Fits You?
Try the cheaper fixes first. Negotiate the price, make a larger down payment, take a smaller cash-out, or wait for a lease renewal at a higher rent. A larger down payment lowers the payment and can lift the ratio. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
If the ratio still falls short, sort by profile:
- Rent falls just short, credit is strong, cash is deep: a sub-1.0 path, with leverage and terms adjusted.
- You own a primary residence, the property is occupied, and equity is strong: a no-ratio path may fit.
- The property is vacant, or you are a first-time homebuyer: no-ratio is not available, so plan around the rent test or a lower price.
- Reserves are thin: fix that before choosing a path, because a thin file fails on any of them.
Skip both paths if you cannot sustain the monthly gap. A path that approves the file does not pay the shortfall for you.
Where Files Stall
Most stalled files trace back to a short list. An overstated rent assumption comes back lower on the appraisal. An insurance quote lands above the modeled figure. Reserves sit in an account that does not count, or a large deposit has no paper trail. A credit score lands a tier below what the leverage assumed. And the borrower cannot carry the gap for as long as they thought.
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
Can I get a loan if the rent does not cover the payment?
Sometimes. A sub-1.0 path is available through select lenders in the network, with leverage and terms adjusted. A no-ratio path is available only through select lenders, generally for borrowers who already own a primary residence. Both are subject to lender guidelines and property review.
Is no-ratio the same as sub-1.0?
No. A sub-1.0 file still calculates the ratio and accepts the shortfall. A no-ratio file never uses it. The two carry different leverage limits and eligibility rules.
Do cash-out proceeds count as reserves?
It depends on the program. Some lenders count them and others do not, so confirm before you plan around them.
Does clearing 1.00 mean the rental will cash flow?
No. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities and capital costs sit outside it.
What credit score do these paths need?
A 620 floor exists in parts of the network, and most programs want around 660. A score of 700 or higher unlocks the strongest leverage tiers. The no-ratio path asks for a minimum of 640.
