The Quick Read: Market rent alone fits vacant, between-tenant, or newly renovated properties, while the lower-of rule fits properties with a signed lease already in place. Neither one is a federal rule. Each is a program convention that varies by lender, and on a super jumbo balance the choice can decide whether the coverage ratio clears.
- Market rent comes from the appraiser’s rent schedule, not from the borrower’s asking price.
- Lower-of takes the smaller of the signed lease and the appraiser’s opinion.
- An above-market lease earns nothing extra under lower-of, because it is capped at market.
- A below-market lease pulls coverage down even when the property could rent for more.
- Value and rent are two separate tests, so a file with plenty of equity can still be limited by rent.
Here is the honest split. Market-rent-only is for the investor with a vacant or transitional property, or a legacy tenant paying under market. Lower-of is for the investor with a clean, fixed-term lease near market. Across the wholesale network, both bases exist, and which one applies depends on the program. Lendmire is a broker, so the useful move is learning which basis a program uses before the appraisal is ordered. Lendmire’s complete DSCR loans guide covers the wider mechanics.

Side-by-Side
The table shows published industry norms for each basis. Specific programs vary, and every file is subject to underwriting.
| Factor | Market rent only | Lower of lease or market |
|---|---|---|
| Review basis | Appraiser’s rent opinion | Smaller of lease and appraisal |
| Documentation | Rent schedule from appraisal | Executed lease plus appraisal |
| Property types | 1-4 units, condos | 1-4 units, condos |
| Entity vesting | Typically allowed | Typically allowed |
| Vacant property | Works as written | No lease, so market rent stands |
| Above-market lease | No effect | Capped at market |
| Below-market lease | No effect | Lowers rent used for lender review |
| Reserve expectations | Set by the program, not the basis | Set by the program, not the basis |
Neither column changes the leverage ladder or the reserve count. Those come from loan size and the program, not from the rent basis.
How the Appraiser Builds Market Rent
The appraisal produces two separate opinions. Value drives leverage. Rent drives coverage. They do not move together.
For a single-family home or one-unit condo, the appraiser documents estimated monthly market rent on Form 1007. Fannie Mae’s Appraiser Update describes the form as the place to record monthly market rent for a single-family investment property, and notes it can be used for condos. Two-to-four-unit properties use Form 1025, which carries rent unit by unit. Those forms originate in agency lending. DSCR loans are not agency products, so this is contrast only. Non-QM programs borrow the form names and the method.
The appraiser pulls rent comparables and adjusts for differences. Comps should be leased on monthly terms. Asking prices on listing sites are not substitutes. Multi-unit comps need to match unit count, which often produces a realistic but low-end number. That is a common reason a file’s rent comes back lighter than the investor modeled.
The ratio itself is simple. Monthly rent divided by the full monthly obligation: principal, interest, taxes, insurance, and any association dues. On interest-only structures, the qualifying obligation drops the principal piece.
When Market Rent Only Is the Better Fit
Market-rent-only wins in four situations.
Vacant property. No lease exists, so the appraiser’s number stands alone. This is the natural basis for a purchase of an empty property or a refinance between tenants.
Below-market legacy lease. Say you own a rental where a long-term tenant pays well under current comps. Under a lower-of program, that lease drags the number down. Under market-rent-only, the lease is not the basis, so coverage reflects what the property could rent for. The loan officer’s question before the appraisal is ordered: which basis does this program use?
Month-to-month or expired lease. Many programs treat these as market-rent situations, since there is no fixed term to rely on.
Heavy renovation or repositioning. When the in-place rent no longer reflects the property, the appraisal is the better evidence.
The trade-off is dependence on the appraiser. If comps come in light, there is no lease to fall back on. A well-documented reconsideration request, with recent leased comps and condition adjustments, is the normal remedy.
When Lower-of Is the Better Fit
Lower-of fits the investor with a fixed-term lease at or near market. The lease and appraisal agree, the documentation is clean, and the program may simply expect both.
Above-market lease. Here the rule cannot hurt you, but it cannot help either. Rent used for lender review is capped at the appraisal. A high lease does not raise the ratio.
Related-party or friendly tenants. A lease with a family member at an unusual number invites questions. Lower-of removes the incentive to paper a high rent, which is why lenders use it.
Stable, renewed leases. If the lease was renewed at market and proof of payment is in the file, the number lines up and the deal works through review with fewer open items.
The cost shows up on the downside. A below-market lease pulls coverage down even when the appraiser says the property could rent for more. On a super jumbo balance, that matters more than on a small loan, because taxes and insurance do not shrink when rent does. A small rent miss moves the ratio by more than its percentage looks like.
Why Super Jumbo Files Feel the Rule Harder
Nothing in the public material shows the rent rule changing with loan size. What changes is the size of the consequence.
Across the wholesale network, the super jumbo ladder runs from $150,000 to $10,000,000, with the standard program stopping at $3,000,000. Leverage steps down as the balance rises: 80% on purchases to $1,000,000, 75% to $3,000,000, 65% to $4,000,000, and 60% to $6,000,000 on case-by-case review. Cash-out runs 75% to $1,000,000, 70% to $1,500,000, 60% to $3,000,000, and none above $3,000,000. All of that is subject to underwriting.
Coverage of 1.00 earns full leverage. Through select programs, coverage from 0.75 to 0.99 is a real path to $2,000,000 at reduced leverage, with LTV and terms adjusting, subject to underwriting. Interest-only for 120 months to 75% is reviewed on the interest, taxes, and insurance alone, which can lift a lease that sits just under market over the line.
Two further points. Above $2,000,000, two appraisals are required, so the rent opinion gets a second look. And reserves are typically six months on the subject property, with credit at 660 or higher and 700 above $3,000,000.
One scenario. Picture a $2.5 million rental with a lease at 90% of the appraiser’s market rent. Under market-rent-only, coverage reflects the full appraisal. Under lower-of, coverage reflects the lease. If the market-rent version clears 1.00 and the lease version lands near 0.92, the second file needs a different structure: interest-only qualification, a reduced leverage tier, or a sub-1.00 select program. Whether any of those apply is a lender call, subject to underwriting and credit review.
Short-Term Rentals and Multi-Unit Edge Cases
Short-term rentals do not run on either basis. Form 1007 records monthly rent, and Fannie Mae’s guidance is that it does not estimate a nightly fee. McKissock’s appraisal education adds that the appraiser addresses value rather than business income, and the lender decides the income. Multiplying a nightly rate by 30 does not produce a valid market rent.
Across the network, short-term-rental files qualify on documented operating history, or on the appraisal’s short-term-rent analysis on a purchase, at 80% of gross. They require coverage of 1.00 or better, top out at $2,000,000, and suit experienced investors.
On 2-4 unit properties, each unit carries its own rent, with a rent roll behind it. Under lower-of, each unit resolves separately.
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.
Where the Rule Bends
There is no single rule. Some programs use market rent alone. Some use the lower figure. A few may weigh the lease more heavily on a refinance with documented payment history. Rent-controlled or stabilized units may be governed by legal registered rent, so that figure belongs in the file early.
Entity vesting does not change the basis in most programs. LLC borrowers are typically welcome, subject to program terms, without layered entities.
The fix ladder, from lightest to heaviest:
1. Correct factual errors in the appraiser’s comps, such as wrong unit count or bedroom count.
2. Submit a reconsideration packet with recent leased comps.
3. Renew a below-market lease at market, if the tenant agrees and payment proof can be documented.
4. Request interest-only qualification, where the program allows it.
5. Take less leverage so the ratio clears.
6. Move to a program that uses market rent alone, or a select sub-1.00 path.
For a closer look at how lenders choose between the two figures, Lendmire’s piece Lease Rent vs 1007 Market Rent: Which Figure a DSCR Lender Uses walks through the comparison.
Documents to Prepare
- Executed lease and any renewal, with proof of recent rent payments.
- Rent roll for 2-4 unit properties.
- Entity documents if vesting in an LLC.
- Reserves documentation on the subject property.
- Evidence of regulated rent, if it applies.
- Recent leased comps, in case a reconsideration request is needed.
A short note on the common misses. Investors model on asking rents. Investors assume a high lease raises the ratio. Investors treat a ratio above 1.00 as proof the property cash flows. It does not. The ratio counts only the monthly obligation, so repairs, vacancy, management, and utilities sit outside it. 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.
The Balanced Verdict
Choose market-rent-only when the lease is stale, below market, absent, or about to expire. Choose lower-of when the lease is clean and near market, because the two numbers will agree and the file is simpler. If your lease is above market, neither basis rewards it. If your lease is below market, the basis matters more than almost any other variable on the file.
If you are buying or refinancing a high-balance rental property and want to see how the numbers work, Lendmire can help you compare super jumbo DSCR loan options based on the property income, the loan balance, credit profile, leverage, and investor goals. Any estimate from the calculator is illustrative only. Nothing here is a commitment to lend.
Frequently Asked Questions
Is the lower-of rule a federal requirement?
No. Some programs use market rent alone, and others use the lower figure. Ask which basis applies before the appraisal is ordered.
Does an above-market lease raise my coverage ratio?
Not under lower-of. Rent used for lender review is capped at the appraiser’s opinion. Under market-rent-only, the lease is not the basis at all.
What form produces the market rent number?
For single-family and one-unit condos, the appraiser uses Form 1007, per Fannie Mae’s guidance. For 2-4 units, the appraiser uses Form 1025 with unit-level rent. These are agency forms borrowed by non-QM programs.
Can I qualify below 1.00 coverage on a super jumbo loan?
Through select wholesale programs, coverage between 0.75 and 0.99 is a path to $2,000,000, with reduced leverage and adjusted terms, subject to underwriting. Above $2,000,000 the options narrow.
How much does a second appraisal matter?
Above $2,000,000, two appraisals are required. That gives the rent opinion a second check, so documented comps and clean unit data carry more weight.
