The Quick Read: The lender counts rent unit by unit, adds the units together, and tests that total against one payment on the new loan. Each unit needs its own supportable rent figure, and the lender’s appraisal, not your pro forma, sets the number that counts. All of this is subject to lender guidelines.
- Every unit gets its own rent figure, backed by a lease, deposit records, or the appraiser’s market-rent opinion.
- Many programs count the lower of the lease rent and the market rent for each unit.
- Vacant units are usually counted at the appraiser’s market rent, though treatment varies by program.
- Value and rent each cap the loan, and the lower limit wins.
- Clearing 1.00 coverage is not the same as positive cash flow.
You bought a fourplex with a short-term bridge loan. You rehabbed it. Now you need a permanent loan that pays off the bridge. The exit lender will not ask what you earn. It will ask what each unit rents for, and it will decide for itself.

This piece walks through that process in order. It covers what the lender is testing, how multi-unit rent gets built, where the standard rule bends, and what to decide before you ever close on the bridge.
Key Terms Defined
DSCR (debt service coverage ratio): The monthly rent the lender counts, divided by the full monthly housing payment on the new loan.
PITIA: Principal, interest, taxes, insurance, and any association dues. That is the full payment used as the divisor.
Rent roll: A list of every unit, its tenant, its lease terms, and its rent.
Appraisal rent schedule: The appraiser’s unit-by-unit opinion of what each unit should rent for at market.
Lower-of rule: The practice of counting the lower of the lease rent and the market rent for each unit.
Seasoning: The waiting period between buying the property and refinancing it. It is lender policy, not law.
Rent-ready: A unit that is finished, leased or leasable, and can be documented as producing rent.
What Is a BRRRR Rehabber Actually Proving at the Exit?
You are proving two things: the building is worth enough, and it rents for enough. The lender checks both, and the weaker result sets your loan size.
BRRRR stands for buy, rehab, rent, refinance, repeat. The bridge or hard money loan covers the first stages. The DSCR loan replaces it. 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. Your own paycheck is not the test. The building is.
| Factor | Bridge loan | DSCR exit loan |
|---|---|---|
| Job | Buy and rehab | Replace the bridge |
| Tested on | Purchase and rehab plan | Value and rent today |
| Rent evidence | Mostly projected | Leases, deposits, appraisal |
| Failure mode | Term runs out | Payoff exceeds the loan |
The last row matters most. The bridge payoff keeps growing through interest, extensions, and fees while you wait. The new loan has to cover it. If the appraisal comes in light or the rent figure is weak, you can end up short at the closing table with a maturing bridge behind you.
For the wider picture, Lendmire’s complete DSCR loans guide covers how these loans are structured. Across the wholesale network Lendmire works with, most purchase files land at 75%–80% LTV on an investment property, and cash-out refinances top out around 75%. Those are typical ranges, and every file is underwritten individually. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
How Does the Lender Build the Rent Number on 2–4 Units?
The lender builds it one unit at a time. Each unit gets a rent figure, the figures are summed, and the sum is divided by a single payment for the whole building.
Here is the sequence on a typical file.
1. The new lender orders its own appraisal. On two to four units, the appraiser typically uses Form 1025. Fannie Mae’s Selling Guide lists that form for two- to four-unit appraisals, including units in planned developments, condos, and co-ops. A DSCR loan is not an agency product. The form name is borrowed, and agency rules do not govern the loan.
2. The appraiser records rent per unit. According to an appraiser’s explainer on Form 1025, the form captures rent unit by unit, not as one blended number. Those figures roll into an operating income statement covering gross rent, a vacancy and expense allowance, and net income.
3. The lender compares lease rent to market rent for each unit. Many programs count the lower of the two. This varies by program, so confirm it before you plan around it.
4. Vacant units usually count at market rent. The appraiser’s opinion stands in for a lease that does not exist yet.
5. The unit figures are added together. That is the numerator.
6. One PITIA payment is the divisor. It covers the whole building, including taxes, insurance, and any dues.
A one-unit property uses a different form. A form description from an appraisal firm separates the 1007 single-family rent schedule, the 1025 for small income properties, and Form 216, the operating income statement. That is useful context. You will see these names in your appraisal order.
Why multi-unit can cover better than single-family
A fourplex puts four rent streams against one payment. The payment does not scale up four times, but the rent does. So coverage often looks stronger than on a single-family rental at a similar price. That is practitioner experience, and it varies by building.
Run the numbers this way, using modeled index figures rather than market data. Say a single-family rehab covers its payment at about 1.05x. A rehabbed fourplex bought with the same leverage might cover closer to 1.25x, because its combined rent is larger against its one payment. Same borrower, same percentage down, different ratio. The building did the work.
What Does the Lender Do With a Messy Rent Roll?
Rent rolls are rarely clean after a rehab. A worked example shows the effect. Picture a rehabbed fourplex, using illustrative index figures only.
| Scenario | Rent counted | Coverage read |
|---|---|---|
| All four leased at market | Full lease total | Around 1.25x |
| One unit vacant | Three leases plus market rent for the fourth | Around 1.20x |
| One lease well below market | Lower-of rule pulls that unit down | Around 1.10x |
| Vacant unit and cheap lease together | Both effects stack | Near 1.05x |
Notice the middle rows. A vacant unit is not always a disaster, because the market-rent opinion can fill the gap. A single cheap legacy lease can hurt more, because the lower-of rule drags that unit down no matter what the building could earn.
Above-market leases work the other way, but only slightly. Rent collected above market is real money. It typically does not raise the counted rent, because the market figure caps it.
What Evidence Does Each Unit Status Need?
Match the document to the unit. Every status needs something in the file, and the weak spots are where files stall.
| Unit status | What supports the rent |
|---|---|
| Leased, long term | Signed lease, deposit records |
| Newly leased | Signed lease, first month’s rent, security deposit |
| Month-to-month or expired | Prior lease plus deposits; market rent often stands in |
| Vacant | Appraiser’s market-rent opinion |
| Short-term rental | Platform history or market-data report |
The newly leased row is the one rehabbers underestimate. A formal lease, bank deposit verification, and proof of the first month’s rent and deposit are the usual document gaps. Missing paper, not weak rent, is a common reason a file stalls. Investors hit exactly this snag, so it is better to plan around it from the start.
Month-to-month and expired leases make a weaker file, not a blocked one. The appraiser’s market rent typically fills the hole.
Short-term rentals run on separate program rules. Across the network, STR purchases go up to 75% LTV, refinances sit around 70%, and cash-out tops out at 70% on short-term-rental collateral. Expect a 640+ score and about 12 months of hosting history. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
How Do You Time Lease-Up Against the Seasoning Clock?
Work backward from the bridge maturity date. Every step has to fit before it, with room to spare.
The seasoning clock typically runs from title recording, not from the day the rehab ends. About six months is the common expectation on a cash-out refinance across the network. Some rate-and-term refinances have shorter waits or none, and policies differ by lender. A plan that assumes cash-out proceeds on the new appraised value, with no allowance for the wait, is a common stall.
A sensible reverse timeline looks like this:
1. Bridge maturity and extension options.
2. Appraisal order and underwriting.
3. Rent roll finalized, tied to the leases.
4. Leases signed on every unit you can.
5. Rehab finished unit by unit.
6. Seasoning clock, which started at purchase.
Sequence your rehab so units become rent-ready one at a time. A finished unit with a signed lease gives the file real evidence. A finished unit sitting empty leaves you relying on the appraiser’s opinion. If a unit’s lease runs below market, fixing it before the refinance can raise the counted rent. If you can’t fix it, plan the loan around the lower figure.
The bridge term has to outlast seasoning, lease-up, appraisal, and underwriting. If it doesn’t, you are negotiating an extension from a weak position. Lendmire’s piece How a BRRRR Rehabber Stress-Tests the DSCR Exit at Hard Money Close covers how to test that timing before you sign the bridge.
An early refinance inside the seasoning window is possible in some cases. Many lenders then size the loan on your cost basis, meaning purchase plus documented rehab, instead of the appraised value. That can cut your proceeds well below what the new value suggests.
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.
When Does Rent, Not Value, Cap the Loan?
When the market-rent opinion is weak. The lender sizes to the lower of two limits: the LTV limit on value and the coverage floor on rent. A strong appraisal does not help if rent is the tighter limit.
Take a rehabbed building that appraises well. You request the maximum leverage the program allows. But the rent supports less debt than the value does. The coverage test caps the loan, and your payoff comes up short. That is rent acting as the binding constraint.
Here is the part many new investors miss. DSCR compares rent to PITIA only. Clearing 1.00 is not positive cash flow. Repairs, vacancy, management, utilities, and capex sit outside the ratio. On a fourplex, one empty unit is 25% of the rent. The ratio might survive it while your actual monthly cash does not.
Across the network, 1.00 is where many select programs start, and stronger ratios open better pricing and leverage. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. A larger down payment can lift the ratio by shrinking the loan. It does not erase leverage caps, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
One practical broker observation: files on small multi-unit buildings that fail usually do not fail on the headline number. They fail on documentation, a mismatch between the rent roll, the leases, and the appraisal’s per-unit conclusions. When those three tell the same story, the file reads cleanly. When they differ, expect questions.
Where Does the General Rule Break?
Several edge cases change the math.
- Legacy tenant below market. One cheap lease pulls down the total, because the comparison runs unit by unit.
- Partly vacant building. Treatment of an empty unit varies by program. Confirm it before you make an offer on the bridge.
- Five or more units. That moves out of the 2–4 unit residential lane. Plan for different underwriting and confirm eligibility early.
- Agency delayed financing. It does not rescue a BRRRR in this situation, because it needs a cash purchase, and a hard-money-financed rehab does not fit that pattern.
- Ineligible property types. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs.
- Large loans. Standard programs run up to $3,000,000. Above $2,500,000 the network generally holds to 30-year fixed structures. Reserves commonly run around six months of PITIA and step up to about nine months above $1,500,000, though they vary by lender, leverage, and transaction type.
Credit also shapes the exit. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Extended terms and interest-only periods are available through select lenders for investors who want them.
What Should You Check Before You Buy?
Model rent the way the lender will, not the way you hope. A short checklist before the bridge closes:
1. Estimate each unit’s market rent conservatively, then cut the weakest unit further.
2. Run coverage against the full payment on the larger exit loan, including taxes, insurance, and dues.
3. Test the one-vacant-unit case and the one-cheap-lease case.
4. Pick your exit lender before the bridge closes, and get terms in writing.
5. Set a pass trigger: if the conservative case fails, sell or renegotiate.
If the exit already looks tight, walk away at the offer stage. Lendmire’s hard money exit checklist lays out the steps in order. An illustrative calculator on the site can help you test coverage scenarios, but treat its output as an estimate only.
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
Do vacant units count toward the rent?
Usually yes, at the appraiser’s market rent, though treatment varies by program. A vacant unit with no lease gets less support than a leased one. If the building is partly empty, confirm the program’s treatment before you make the bridge offer.
Which rent counts if a lease is above market?
Typically the market figure. Many programs count the lower of lease rent and market rent for each unit. The extra rent you collect is real income, but it usually does not raise the ratio.
Is a signed lease required on every unit?
Not always. A lease and deposit records give the strongest support. Without one, the appraiser’s market rent often stands in, which usually makes a weaker file rather than a blocked one.
Does finishing the rehab restart seasoning?
Generally no. The clock typically runs from title recording, and it is lender policy. About six months is the common expectation on a cash-out refinance, while some rate-and-term refinances are shorter.
Does my after-repair value estimate set the loan?
No. The new lender’s appraisal and its rent figure set the loan. Your estimate is a planning tool, not an underwriting input.
