The Quick Read: On a six-unit building, the loan amount is the lowest of three limits: the leverage cap applied to appraised value, the debt the building’s net operating income can carry, and the program’s size ceiling. In expensive coastal markets, the income test usually binds first, so the loan often lands below what the purchase price suggests.
- Six units sit outside the standard 1-4 unit DSCR track and are reviewed on net operating income, not gross rent.
- Leverage applies to the appraised value, not the contract price.
- Coastal insurance, especially wind and flood, lowers income and shrinks the supportable loan.
- Large balances step leverage down, and above $4,000,000 every request is reviewed case by case.
- Every figure here is a ceiling through select wholesale programs, subject to underwriting.
Why Does a Six-Unit Change the Rules?
Five units is where a building stops being treated as a residential property and starts being underwritten like a commercial one. Across the wholesale network Lendmire works with, the standard DSCR program covers one to four units. A six-unit moves to a separate portfolio-style term track with commercial-style review.

Short-term rental figures are estimates only and vary significantly by season, property type, management approach, and local short-term-rental rules — confirm local regulations before relying on them. 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.
That shift changes the income math. On a duplex or fourplex, the lender typically compares gross rent to the full monthly obligation. On a six-unit, the lender builds net operating income (NOI), which is rent after vacancy, management, repairs, reserves, and common-area costs. Coverage is then NOI divided by debt service.
“Super jumbo” has no legal definition. It is a lender label for balances above what the lender treats as ordinary. The only official size line in mortgage lending is the conforming limit. FHFA’s conforming loan limit announcement sets a one-unit baseline of $832,750 and a high-cost ceiling of $1,249,125. Those numbers govern loans that agencies buy. DSCR loans are business-purpose investor loans, so they do not cap or size a DSCR file.
Lendmire is a broker. It arranges these loans through investor lenders in 41 markets, including Washington, D.C., and the lenders underwrite and approve. The complete DSCR loans guide covers the basics if you are new to the product.
Key Terms Defined
- DSCR (debt service coverage ratio): Income divided by the debt payment. A reading of 1.00 means income equals the payment.
- NOI (net operating income): Rent minus operating costs and vacancy, before any debt payment.
- LTV (loan-to-value): The loan as a percentage of appraised value.
- ITIA: Interest, taxes, insurance, and association dues. It replaces PITIA when the loan is interest-only.
- Super jumbo: A lender label for very large balances. It is not a regulatory category.
- Balloon: A loan structure where a large balance comes due at the end of a fixed term.
The Three Limits That Cap Your Loan
The answer is always the smallest of three numbers. Think of three gates in a row. The tightest one sets your loan.
| Limit | What it tests | When it binds |
|---|---|---|
| Leverage | LTV cap × appraised value | Strong rents, low expenses |
| Coverage | NOI vs. debt service | Pricey coastal buildings |
| Program size | Band and ceiling | Very large balances |
Leverage. Leverage steps down as balances grow. Across the network, the best cells run 80% on a purchase to $1,000,000, then 75% to $3,000,000, then 65% to $4,000,000. Above that, 60% applies, on review. A strong score is needed for the top cell in each band, and the program floor is 660 on loans to $3,000,000 and 700 above. These are the ladder figures for the high-balance program. A six-unit takes its leverage from its own term track, which typically tops out near the 75% area on a purchase, subject to underwriting.
Coverage. The lender asks what debt the NOI can support. A reading of 1.00 earns full leverage on the standard track. Select programs go lower, between 0.75 and 0.99, at reduced leverage, and LTV and terms adjust, subject to underwriting.
Program size. The bands run from $150,000 to $10,000,000 on the portfolio investor program, and the standard program stops at $3,000,000. Short-term-rental and no-ratio files stop at $2,000,000.
Why Coverage Usually Binds on a Coastal Six-Unit
Coastal buildings are expensive relative to the rent they produce. Price reflects land, location, and scarcity, while rent reflects what tenants will pay. So the NOI supports less debt than the value would allow. The leverage gate says yes. The coverage gate says not that much.
Run the numbers on a modeled building. Say the appraisal supports the leverage cap, and at that loan size NOI covers debt service only 0.90x. If you want 1.00x coverage, the loan has to shrink by the ratio of the two, or about 10%. Coverage fixes the size, and leverage never gets a vote.
Here is the same logic in reverse. Start with NOI and divide by the coverage you need. That gives the maximum annual debt service. Convert that to a loan size using the note’s terms and amortization. This back-solve is what an underwriter actually does, and it is why investors who shop on LTV alone get surprised.
Which Number Does the Lender Use for Value?
The contract price is not the loan base. The appraised value is. On a six-unit, the appraiser typically capitalizes NOI at a market cap rate. A higher cap rate produces a lower value, and a lower value produces a smaller leverage-based loan.
The standard appraisal form for small residential buildings, Form 1025, covers two- to four-unit properties. A six-unit falls outside it. Practitioners expect a narrative, income-approach report instead, with a rent schedule and operating statement. Above $2,000,000, the program requires two appraisals.
Coastal luxury buildings carry a quiet risk here: thin comparable sales. When the appraiser has to reach for comps, value gets conservative. Check the contract price against a cap-rate-based value before you apply.
How Coastal Insurance Moves the Answer
Insurance is the line item that moves most on coastal files. Wind, hazard, and flood premiums all reduce NOI. Lower NOI means lower supportable debt. Because the loan sizes off income, every dollar of added expense cuts the loan by more than a dollar.
Flood deserves its own check. On federal flood maps, high-risk zones begin with the letters A or V. Lenders typically require flood coverage on buildings in those zones, and that is true of investor lenders even where no federal mandate reaches the loan. Government-backed flood policies carry coverage caps that sit below the replacement cost of many six-units. The gap is usually filled with private excess coverage, which raises the expense line again.
Get a flood determination and an insurance quote before you pick a loan size. Insurance is the number most likely to change between the first estimate and the final file.
Interest-Only or Amortizing?
Interest-only structures help coverage because the payment excludes principal. On the high-balance program, interest-only runs 120 months on 30- and 40-year terms, to 75% leverage, with coverage of 0.75 or better, qualified on ITIA. Whether and how a six-unit term loan offers interest-only is set by that track, so ask before assuming. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
A short fixed term with a balloon is also common on the six-unit track. You are not getting a 30-year fixed here. You are getting a runway, and you need an exit: refinance, sale, or payoff at maturity. A building with unstable income or heavy deferred maintenance makes that exit harder.
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 General Rule Breaks
Several situations bend the three-limits model.
- Mixed-use buildings. Ground-floor retail income enters both the NOI and the appraisal. Commercial leases are reviewed more closely than residential ones.
- Short-term rentals. Coastal markets lean heavily on them, and a six-unit built on STR income is a different file. Under the network’s STR rules, income is documented operating history at 80% of gross, loans stop at $2,000,000, and municipal permission must be documented per property. 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.
- Pooled notes. The term loan can pool properties across markets, and coverage is then measured on the whole pool, not the single building.
- Residential-style underwriting of five to ten units. A few niche lenders use gross rent over payment on these buildings. That makes coverage look higher than an NOI-based test would. It is uncommon, so do not plan around it.
- Unstabilized buildings. A building with vacant units or expired leases does not show the income the lender needs. The appraiser values what is in place.
Which Route Fits Your Six-Unit?
The investor decision comes down to unit count, balance, and what income you can document.
| Route | Units | Income basis | Best fit |
|---|---|---|---|
| Standard DSCR | 1-4 | Gross rent | Smaller coastal rentals |
| High-balance ladder | 1-4 | Gross rent | Luxury 1-4 unit, to $10M |
| Portfolio term loan | 5+ | NOI | Six-unit, stable income |
| Agency small-balance | 5+ | Agency rules | Smaller, conforming balances |
Lendmire’s piece on how super jumbo DSCR compares with agency small-balance financing on a coastal six-unit lays out the agency side in detail.
Who This Does Not Fit
Owner-occupants should look elsewhere, because these are business-purpose loans on investment property. A building with major deferred maintenance, mostly vacant units, or an unclear permit history is also a hard fit. Above $3,000,000, the network’s overlay excludes rural property, and credit needs to be 700 or higher with citizens and permanent residents only.
What to Bring
A sound six-unit file usually includes:
- A rent roll and current leases for every unit.
- Twelve months of operating statements.
- Entity papers if you vest in an LLC, subject to program terms.
- A credit report and proof of reserves. Reserves are typically six months of PITIA on the subject (twelve for first-time investors), and cash-out proceeds never count toward them.
- An insurance quote and a flood determination.
Frequently Asked Questions
Does “super jumbo” apply to a six-unit building?
It can, but the term is a lender label with no official definition. On a six-unit, what matters is the loan track. Five or more units move to a portfolio-style term loan reviewed on NOI. The high-balance ladder to $10,000,000 is built around one to four units.
Is there a legal cap on how much a DSCR loan can be?
No. The conforming limit only governs loans the agencies buy, so it does not size a DSCR loan. The practical caps are the program ceiling, the leverage cap, and what the income supports.
What if the rent does not cover the payment?
Select programs in the network review coverage between 0.75 and 0.99, at reduced leverage, and LTV and terms adjust, subject to underwriting. On a six-unit, the realistic fix is usually a smaller loan, a larger down payment, or a lower expense stack.
Does flood insurance count against coverage?
Yes. Premiums are an operating expense, so they lower NOI and reduce supportable debt. Lenders typically require flood coverage in high-risk zones.
Can I use an LLC and cash out?
Entity vesting is welcome, with no layered entities, subject to program terms. Cash-out has its own limits: none above $3,000,000, and unlimited proceeds only at or below 60% LTV on the high-balance program. A six-unit term loan sets its own cash-out rules. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
