The Quick Read: A DSCR loan is reviewed for a rental primarily on property-level income covering the payment, subject to lender guidelines. A conventional loan is reviewed for the borrower’s personal income and debts. For a new landlord with an accessory dwelling unit (ADU), the choice usually turns on occupancy, documentation, and whether the ADU is legal and supported by the appraisal.
- DSCR compares total monthly rent to PITIA (principal, interest, taxes, insurance, and any HOA dues). It does not review personal income.
- Conventional underwriting reads tax returns and debt-to-income (DTI). A new landlord with solid traditional employment income and one rental may fit it well.
- ADU rent counts under DSCR when the unit is legal and the appraisal supports it. Unpermitted ADUs are often left out.
- A conventional ADU credit exists only for an owner-occupied one-unit home, with a cap. It does not extend to a pure rental.
- Neither loan requires prior landlord experience, but experience changes how rent is treated.
The honest answer on who each option fits: conventional is for the borrower with income room, clean tax returns, and a property they will live in or hold in their own name. DSCR is for the investor whose DTI is stretched, whose income is hard to document, or who wants to buy through an LLC, subject to program terms. This article refers to DSCR loans as business-purpose investor loans, designed for non-owner-occupied rentals. They are reviewed differently from a standard owner-occupied mortgage.

Side-by-Side
The DSCR column reflects how select lenders in Lendmire’s wholesale network typically work. The conventional column shows published industry norms, which vary by lender.
| Factor | DSCR loan | Conventional loan |
|---|---|---|
| Review basis | Property rent vs. PITIA | Borrower income and DTI |
| Documentation | Appraisal, lease, rent schedule, entity papers | Tax returns, pay records, asset statements |
| Property types | 1-4 unit rentals, with eligibility limits | Owner-occupied and investment homes |
| Entity vesting | LLC possible, subject to program terms | Usually personal name |
| ADU rent | Counted if legal and appraisal-supported | Owner-occupied one-unit only, with a cap |
| Reserves | Commonly around 6 months PITIA | Vary by lender and occupancy |
| Prior landlord history | Not required | Not required, but it affects rent treatment |
| Scaling | Property-by-property | Often limited by financed-property counts |
Timelines differ by file and lender, and this table does not compare them. Pricing lives in the calculator, not here.
How DSCR Counts Rent
DSCR is monthly rent divided by PITIA. Across Lendmire’s wholesale network, 1.00 is where select programs start. A separate select-lender path goes below 1.00, with leverage and terms adjusted. Stronger ratios open better leverage and pricing.
One caution on the math. Clearing 1.00 does not mean the property cash flows. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation.
The rent figure comes from the appraisal. An appraiser reports market rent on Form 1007 for a single-family home or Form 1025 for a 2-4 unit property. Where a lease exists, underwriters generally compare it to market rent. A vacant unit relies on the market figure alone. For a new landlord, no rental history is not a barrier. The appraisal supplies the evidence.
How ADU Rent Counts Under DSCR
ADU rent is added to the main unit’s rent in one property-level ratio. Two things decide whether it counts: legal status and appraisal treatment.
Legal and permitted. If the ADU is permitted and the appraiser reports it, its rent can lift the ratio.
Unpermitted. This is the biggest swing factor. An unpermitted ADU is often excluded from both value and rent. Run the file without it before assuming it helps.
Existing but unleased. Market rent from the appraisal may support it if the unit is legal. Lender treatment varies by program.
Planned or unbuilt. With no rent history and nothing for the appraiser to inspect, it is generally not credited.
Multiple ADUs. Programs commonly count only one. Confirm with the lender before building a plan around two.
Short-term use of the ADU. 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. On the network’s short-term-rental programs, purchase leverage tops out at 75% LTV, cash-out at 70%, and refinance sits around 70%. Those programs expect a 640+ score and about 12 months of hosting history. Purchases and refinances each carry a 1.00 coverage floor. Lendmire’s piece ADU Short-Term vs Long-Term Rent on a DSCR Loan: Which Counts More covers that choice in depth. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
The practical step: run the numbers both ways. Count the ADU and exclude it. If the file clears coverage either way, the ADU is upside. If it only works with the ADU, the legal paper trail becomes the whole file.
How ADU Rent Counts Under Conventional
Conventional treatment is narrower. Fannie Mae’s DU 12.1 release note describes an ADU credit tied to a one-unit principal residence, available on purchases and limited cash-out refinances. Per the Appraisal Institute reprint, rent from only one ADU may be used, and it can’t exceed 30% of the borrower’s total qualifying income. The same reprint flags double-counting risk between appraised value and rent.
The takeaway for a landlord: that credit belongs to an owner-occupant. A buyer purchasing a rental does not get it. This is contrast only. Agency rules do not govern DSCR files.
For existing rental income, Fannie Mae’s Selling Guide points to Schedule E or Form 8825 documentation, which means a rental needs filed history before it reads as income. A first-time landlord has none. That is why rent on a brand-new rental is often handled conservatively in conventional files, and why income from a brand-new ADU can be limited.
When Conventional Is the Better Fit
Conventional fits when these line up:
- The borrower has steady Traditional employment income and DTI room for the new payment.
- Tax returns are clean and easy to document.
- The property is an owner-occupied one-unit home with an ADU, and the ADU credit and its cap suit the numbers.
- The investor plans a long hold, takes title personally, and does not need an LLC.
- The borrower expects to stay under any financed-property count a lender applies.
That is a fair read. A DSCR loan is not automatically the better product for a salaried first-timer.
When DSCR Is the Better Fit
DSCR fits when:
- DTI is stretched, or income is hard to document because of self-employment or heavy write-offs.
- The buyer wants LLC title, subject to lender program eligibility. A property held in an LLC generally can’t take a conventional loan without moving title back to the individual.
- The property is a non-owner-occupied rental, so the conventional ADU credit does not apply.
- The investor is scaling and does not want each new loan stacked into personal DTI.
- The rent, including a legal ADU, covers the payment with room.
DSCR is not a no-underwriting loan. The file still needs an appraisal, rent schedule, credit review, and reserves.
What Program Terms Look Like on the DSCR Side
These are typical ranges across select lenders in the network, subject to lender guidelines. They are not commitments to lend.
- Purchase leverage: most files land at 75%-80% LTV on an investment purchase.
- Cash-out refinance: tops out around 75% LTV on a standard rental.
- Credit: a 620 floor exists in parts of the network. Most programs want around 660, and 700+ opens the strongest tiers.
- Loan size: roughly up to $3,000,000 on standard programs.
- Reserves: commonly around 6 months of PITIA, stepping up to about 9 months above $1,500,000. Some conservative files see reserves waived.
- Not offered: manufactured homes, log homes, and barndominiums fall outside these programs.
A larger down payment lowers the payment and can lift coverage. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rent.
Key Terms Defined
DSCR: the ratio of a property’s monthly rent to its PITIA payment.
PITIA: principal, interest, taxes, insurance, and any HOA dues, the full monthly housing obligation.
DTI: debt-to-income, the share of a borrower’s income that goes to debt payments. Conventional underwriting weighs it. DSCR does not.
ADU: an accessory dwelling unit, such as a garage conversion, basement unit, or detached backyard unit.
Form 1007 / Form 1025: appraisal forms that report market rent for a single-family home and a 2-4 unit property.
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.
Run the Same Property Both Ways
Picture a new landlord buying a duplex-style property with a permitted ADU in the back. First, run coverage with only the main unit’s rent against PITIA. Say the ratio lands just under 1.00. Then add the appraised ADU rent. Say it moves to roughly 1.2x. That swing is the whole story: with the ADU, the file sits in clean territory. Without it, the file points to a select-lender path below 1.00 with leverage and terms adjusted.
Now flip the property. If the ADU is unpermitted, the appraiser may leave it out of both value and rent. The file reverts to the first number. That is why legal paperwork should be gathered before the file goes in, not after.
Common Misconceptions
ADU rent always counts. It depends on legality, appraisal treatment, and program rules.
Conventional can’t count ADU rent. It can, but only for an owner-occupied one-unit home, with a cap.
DSCR means no documents. It means no personal income documents. The property still needs an appraisal, rent schedule, and lease.
Prior landlord experience is required. Neither route requires it, though it changes how rent is read, especially on conventional files.
What to Gather Before You Apply
- Permit and zoning paperwork for any ADU.
- A signed lease for each unit, or a plan to rely on appraised market rent.
- Entity documents if buying through an LLC.
- Insurance quotes covering every unit.
- Reserve statements.
- For a conventional file: tax returns, pay records, and asset statements.
The Verdict
Pick by income room and rent evidence. A salaried first-timer buying a home to live in, with DTI room, may do well on conventional. A landlord buying a pure rental, wanting LLC title, or running into DTI limits is the natural DSCR borrower. In both cases, ADU rent helps only when the unit is legal and documented. Tax treatment varies; consult a qualified professional.

Frequently Asked Questions
Do I need landlord experience for a DSCR loan?
No. Across the network, prior landlord history is not a requirement. The appraisal supplies market rent when there is no lease or track record. Credit, reserves, and property eligibility still apply, subject to lender guidelines.
Does conventional financing count rent from a rental ADU?
Only in a narrow case. The credit applies to a one-unit principal residence on a purchase or limited cash-out refinance, with one ADU and a 30% cap on qualifying income. A non-owner-occupied rental does not get it.
Can I refinance from DSCR to conventional later?
Often yes, if the borrower later meets conventional standards on income, DTI, title, and occupancy. Moving out of an LLC may be required. Compare the full cost of the switch before acting.
What if the ADU is not permitted?
Plan on it being excluded from both value and rent. Run the file without it. If coverage only works with the ADU, resolve the permit question before applying.
Can I live in the property and use a DSCR loan?
DSCR loans are built for non-owner-occupied rentals. An owner-occupant buyer should look at conventional options first.
