The Quick Read: A conventional loan on a rental qualifies you, the borrower, by looking at your income, debts, credit and savings, then counts only part of the rent as help. A DSCR loan flips that. It qualifies primarily on property-level rental income covering the payment, subject to lender guidelines.
- Conventional means the loan follows the guidelines of the big agencies that buy mortgages, not a government insurance program.
- Your personal income and debt-to-income ratio decide the outcome, even if the rent looks strong.
- Lenders haircut rent, so a property can cash flow in real life and still count against you on paper.
- Conventional often costs less when your documented income fits. It stops fitting as your portfolio grows or your tax returns get complicated.
- Across Lendmire’s wholesale network, DSCR loans on an investment-property purchase typically run 75%–80% LTV, subject to lender guidelines.
Here is the plain version. A bank, credit union or mortgage company lends you money on a rental. It checks you first and the building second. That order is the whole story, and most of what follows comes from it.

What Makes a Loan Conventional on a Rental?
A conventional loan is any mortgage that is not insured or guaranteed by a government program. In practice, it follows guidelines set by the agencies that buy loans from lenders. Individual lenders can add stricter rules of their own. Those add-ons are called overlays, and they explain why two lenders give different answers on the same file.
You can use one on a property you will not live in. You pay for that choice, though. Investment loans generally take a bigger down payment, more cash reserves and higher pricing than owner-occupied loans. Pricing includes loan-level adjustments, which are add-on charges based on credit score, leverage and occupancy. Lower leverage generally shrinks them.
Why the extra cost? Landlords walk away from rentals more often than from the home they sleep in. Lenders price for that.
Eligible properties are small residential buildings. That means a single-family home, or a duplex, triplex or fourplex. Anything larger is commercial, and conventional rules do not reach it.
Key Terms Defined
PITIA: the full monthly obligation on the property: principal, interest, taxes, insurance and any association dues.
DTI (debt-to-income ratio): your total monthly debts divided by your gross monthly income. This is the number a conventional underwriter watches most closely.
LTV (loan-to-value): the loan balance as a percentage of the property’s value. A purchase at 75% LTV means 25% down. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
DSCR (debt service coverage ratio): monthly rent divided by PITIA. A result of 1.20 means the rent covers the payment with 20% to spare.
Reserves: liquid savings left after closing, usually counted in months of PITIA.
Adjusted net rental income: the conventional method’s version of rent credit. It is 75% of gross rent minus PITIA.
Overlay: a lender’s own rule, stricter than the baseline guidelines.
How Underwriting Treats the Loan, Step by Step
Underwriting is the lender’s review of your file. Here is how it runs on a conventional rental purchase.
1. Occupancy and property type. You state that the property is an investment. The lender confirms it is residential with four or fewer units, which matches Fannie Mae’s published eligibility language for loans it buys. Occupancy is not a detail to fudge. Calling a rental a primary home is a serious problem, not a pricing trick.
2. Appraisal and rent schedule. The appraiser values the property. When rent is used to qualify, the appraiser also estimates market rent. On a single-family rental that report is Form 1007. On a two-to-four-unit building it is Form 1025. Leases can back it up. Short-term rentals are an awkward fit for Form 1007, which was not designed for nightly stays.
3. Rent credit. This is where landlords get surprised. On a purchase, the lender takes 75% of gross monthly rent and subtracts the full PITIA. The result is adjusted net rental income. The other 25% is treated as a cushion for vacancy and upkeep, whether your building needs it or not.
What happens next depends on your experience. With at least 12 months of rental management experience, a positive result can count as qualifying income. A negative result is added to your monthly debts. With less than 12 months, a positive result can only offset that property’s own payment.
4. DTI. Your income, your existing debts and the rent result all land in one ratio. The lender sets a ceiling, and it varies by file and lender. Cross it and the loan stalls, however well the property rents.
5. Assets and reserves. You need cash for the down payment, closing costs and reserves. Reserve requirements typically rise as you finance more properties. Sizes vary by lender, so ask early.
6. Pricing. The lender prices the loan off your credit score, your leverage and the investment occupancy. Conventional pricing is published and grid-based, which makes it more predictable than many alternatives.
That is the whole machine. Five steps measure you, and one step measures the building.
A Worked Example, Using Ratios Only
These are modeled assumptions, not market data. Say a duplex’s rent covers its full monthly obligation 1.20 times. That is a 1.20 coverage ratio.
A conventional lender takes 75% of that rent. Multiply 1.20 by 0.75 and you get 0.90. The rent credit covers only 90% of the payment. The missing 10% shows up as a monthly debt in your DTI. The building cash flows, and conventional underwriting still treats it as a drag.
Now raise the coverage to 1.40. Seventy-five percent of that is 1.05, a small positive result. If you have under a year of landlord experience, that sliver only offsets the payment. It does not add to your income.
Notice what did not matter in either case. A strong rent-to-payment ratio does not rescue a conventional file on its own. Your personal DTI still decides it.
Structures and Variations You Will Run Into
Purchase versus refinance. On a purchase, the lender works from market rent or a lease. On a refinance of a rental already on your tax return, the lender typically reads the rental schedule on that return instead. It adds back certain items, averages the result and subtracts the payment. Your tax return, not your lease, tells the story.
Existing rentals. Each rental you already own gets its own income-or-loss calculation. The results are then added together. A net gain boosts income. A net loss becomes a debt.
Multi-unit buildings. A duplex or fourplex counts as one property, though it needs the longer appraisal form. Down payments generally rise with unit count.
Cash-out. You can refinance a rental and pull out equity. Conventional cash-out generally carries tighter leverage than a purchase.
Closing costs. Whether you can finance them into the loan depends on the leverage cap and the lender. Lendmire’s piece Can You Roll Closing Costs Into an Investment Property Conventional Loan? walks through it.
Where the General Rule Breaks
The rules above cover the typical file. These situations bend them.
The first-time landlord. Under 12 months of experience means rent can only offset the payment. Your income does not rise. If your DTI was already tight, the rental will not fix it.
The growing portfolio. Agency guidelines cap how many financed properties one borrower can carry. The cap counts properties, not mortgages. A duplex is one. A property whose mortgage you are not personally liable on generally does not count. As you approach the cap, extra reserves apply. Past it, you need a non-agency route such as DSCR or a portfolio loan.
The landlord with messy returns. If depreciation, write-offs or business losses shrink your reported income, conventional underwriting reads the shrunken number. Real cash flow does not matter. Self-employed landlords hit this wall often.
The moved-out homeowner. Rent from a home you just vacated can count toward qualifying, with its own documentation rules. Multi-unit versions need more paperwork.
The short-term rental. Conventional rules treat nightly-stay income more conservatively than a long-term lease, and the appraisal form does not fit well. Hosts with strong booking histories often find DSCR a better match.
The LLC owner. Agency loans lend to individuals, not companies. If you want the property in an LLC, conventional is usually the wrong tool. DSCR programs often allow it, subject to program terms.
The five-unit building. Conventional stops at four units. Bigger buildings need another product.
Conventional vs. DSCR
| Factor | Conventional | DSCR (Lendmire network) |
|---|---|---|
| What is qualified | You: income, debts, credit | The property’s rent vs. PITIA |
| Rent treatment | 75% of rent, net of payment | Full rent over payment |
| Income documents | Tax returns, pay records | Property-focused file |
| Property count | Capped by agency rules | No agency cap |
| Purchase LTV | Set by agency grid | Typically 75%–80% |
Think of it as two different questions. Conventional asks whether you can afford the loan. DSCR asks whether the building can.
The complete DSCR loans guide covers that second path in full. Here are the program realities across the wholesale network Lendmire works with. Select lenders in the network typically allow:
- Leverage: on an investment-property purchase, most files land at 75%–80% LTV, which is 20%–25% down. Select high-leverage programs reach 85% LTV (15% down) with roughly a 700+ credit score.
- Coverage: 1.00 is where many select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger ratios open better pricing and leverage.
- Credit: a 620 floor exists in parts of the network. Most programs want around 660. A 700+ score unlocks the strongest leverage tiers.
- Loan size: up to $3,000,000 on standard programs. Above $2,500,000, the network generally holds to 30-year fixed structures.
- Reserves: commonly around 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000. They vary by lender, leverage and loan size.
- Not offered: manufactured homes (single- and double-wide), log homes and barndominiums.
Two cautions. First, a DSCR above 1.00 is not the same as positive cash flow. The ratio compares rent to PITIA only. Repairs, vacancy, management, utilities and capital costs sit outside it. Second, a bigger down payment can lift coverage by shrinking the payment. It never erases leverage caps, credit floors, reserve rules or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
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. Every file is underwritten individually, and nothing here is a commitment to lend.
How to Decide
This one is a genuine judgment call, and the right answer shifts with your numbers.
Conventional tends to fit when:
- You have steady, well-documented income and a comfortable DTI.
- You own few financed properties.
- Your tax returns show the income you actually earn.
- You plan to hold the property in your own name.
DSCR tends to fit when:
- Your DTI is too high, or your returns understate your real income.
- You are near the agency property-count cap.
- You want the property in an LLC, subject to program terms.
- The building is a short-term rental or sits in a portfolio you are scaling.
Conventional can cost less, but not always. The gap depends on your credit, leverage and the lender, and it sometimes turns out small. Run both versions of the file before you choose. (The cheaper loan on paper is not the cheaper loan if it caps your next purchase.)
Common Landlord Mistakes
- Assuming full rent counts. It does not. Plan for the haircut.
- Ignoring the property count. Your tenth financed property may behave differently from your second.
- Skipping the experience clock. Under a year as a landlord limits what rent can do for you.
- Mixing personal and rental funds. Muddy accounts slow underwriting and raise questions.
- Treating occupancy as a formality. The loan is priced and approved for a specific use. Keep it honest.
- Reading a coverage ratio as profit. Rent over payment is a lender’s test, not your budget.
Tax treatment varies; consult a qualified professional.
Frequently Asked Questions
Can I use a conventional loan on a rental I will never live in?
Yes. Expect a larger down payment, higher pricing and more reserves than on an owner-occupied loan. You also need to qualify personally, since the rent only partly counts.
Does my rental income raise my qualifying income?
Only partly, and only sometimes. The lender takes 75% of gross rent and subtracts the payment. A positive result can count as income with 12 or more months of landlord experience. A negative result adds to your debts. With less experience, a positive result only offsets that property’s payment.
What happens when I hit the limit on financed properties?
Agency-backed conventional loans stop being an option. Investors at that point usually look at DSCR or portfolio loans. DSCR does not use an agency property count, though reserves, credit and leverage still apply under each program.
Is a DSCR loan always more expensive than a conventional loan?
Not always. Conventional often costs less when your income and DTI fit, but the gap varies by file. DSCR trades the personal-income test for property-based qualification, and pricing reflects that. Compare both on your actual numbers.
Can I buy a rental with a lower DSCR than 1.00?
Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. It generally means a larger down payment or different pricing than a stronger-coverage file. Eligibility depends on the lender, your credit and the property.
