The Quick Read: No published formula sets a percentage haircut for distant comps. The effect is indirect, because sparse sales and rental comps push the appraiser toward a more conservative value and a more conservative rent, and those two numbers set the loan size and the coverage ratio.
- A lower appraised value shrinks the loan on a purchase, because leverage is sized off the lower of price or value, and it raises the cash you bring to close.
- A lower appraised rent lowers the coverage ratio, even when the signed leases look strong.
- Most programs credit the lower of the lease or the appraiser’s market rent, so a lease above market rent does not lift the number.
- Distance is rarely a hard cutoff, but some programs treat rural designation or very distant comps as an eligibility question.
- The fixes are mostly front-loaded: give the appraiser closed fourplex sales and rental evidence at the order, and know the program’s rural rules before paying for the appraisal.
A fourplex in a small town is about the most comp-sensitive residential property a DSCR borrower can buy. There are few four-unit sales nearby, few four-unit rentals to measure against, and four separate rent opinions that all have to hold. This article walks through where the damage happens, how to model it without a made-up haircut, and what the investor can do about it. The rest of the DSCR mechanics sit in Lendmire’s complete DSCR loans guide.

How Does a Fourplex Appraisal Use Comps?
The appraisal does two separate jobs on a fourplex file. It produces a value, which drives leverage, and a per-unit market rent, which drives coverage. A 2-4 unit property uses the small residential income property appraisal report, Form 1025, which carries a sales comparison grid, a rent schedule, and an income approach section.
Both jobs depend on comparables. The sales grid compares the building to sold properties. The rent schedule compares each unit to rented units. DSCR is a non-QM product, so each lender sets its own appraisal rules. The network borrows the form names from the agency world and little else.
On a purchase, the loan is sized from the lower of the appraised value or the price. Most purchase files across the wholesale network land at 75%-80% LTV, subject to lender guidelines. Whatever the appraiser concludes becomes the base that percentage is applied to.
Key Terms Defined
Comp: A comparable sold property, or a comparable rented unit, that the appraiser uses to support a value or rent opinion.
Adjustment: A dollar amount the appraiser adds or subtracts to account for differences between a comp and the subject, such as unit count, condition, size, or sale date.
Market rent: The rent the appraiser believes each unit would command, which can differ from the rent in a signed lease.
LTV: The loan amount divided by the lower of price or appraised value.
PITIA: Principal, interest, taxes, insurance, and any association dues, which together form the monthly obligation in the denominator of the coverage ratio.
Coverage ratio (DSCR): Monthly rent divided by PITIA. For a fourplex, the combined unit rents sit over the single building payment.
Why Does a Small Town Stretch the Search?
A small town may have no recent fourplex sales within a convenient radius. Appraisers describe widening the search in stages: they go back further in time with market-condition adjustments, then expand the radius, then loosen the size range, then adjust for feature differences. They also look at competing neighborhoods. McKissock’s appraiser-education guidance says the test is whether comps reflect the same market influences as the subject, not whether they sit inside a fixed distance.
There is also no universal one-mile rule. Appraiser commentary from Robinson Appraisal Group describes the one-mile figure as a lender or investor preference, not an official requirement. A lender overlay can still apply, so the program’s own rules matter more than any rule of thumb.
For contrast, the agency selling guide itself recognizes the problem. Fannie Mae’s comparable sales section says rural markets often lack recent, truly comparable sales nearby, and that sales a considerable distance away can be used when they are the best indicator of value, with the report explaining why. That guide does not govern DSCR files. It shows only that distance itself is not the disqualifier. The explanation and the adjustments are what matter.
A fourplex makes the thin-comp problem worse. Four-unit sales are scarcer than house sales, so the appraiser may reach for duplexes, triplexes, or single-family homes and adjust for the differences. Each adjustment adds a layer of judgment, and a conservative appraiser in an unfamiliar market tends to resolve that uncertainty on the low side.
Two Ways Distant Comps Cut a Fourplex DSCR Loan
The cut arrives through two different channels, and each hits a different test. Value risk hits leverage and cash to close. Rent risk hits coverage. They can happen together, and on a fourplex they often do.
| Channel | Test it hits | What the file looks like |
|---|---|---|
| Value side | LTV cap | Smaller loan, more cash to close |
| Rent side | Coverage ratio | Ratio falls short of the program floor |
| Both together | LTV and coverage | Smaller loan and a thinner ratio |
On the value side, more adjustments for unit count, condition, size, and market timing add uncertainty. Weak or dissimilar comps are the classic cause of a low appraisal. On the rent side, rental comps can be scarce or far away, and time and distance adjustments can produce a lower rent opinion. Four units mean four rent opinions. A small miss on each compounds across the building.
One more point on rent. Most programs credit the lower of the signed lease or the appraiser’s market rent. A strong lease helps the story but does not lift the ratio if the appraiser’s number is lower.
A Modeled Example: One Fourplex, Two Appraisal Outcomes
These inputs are modeled assumptions for illustration, not market data. No source supports a standard percentage haircut, so the example shows the arithmetic of the mechanism and nothing more.
Say a fourplex is under contract with a buyer targeting 75% LTV on a purchase. Run the file two ways: once with close-by comps, and once with distant comps. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
| Step | Close-by comps | Distant comps (assumed) |
|---|---|---|
| Appraised value vs. price | At price | 8% below price |
| Loan base | 75% of price | 75% of the lower value, about 69% of price |
| Cash the buyer brings | About 25% of price | About 31% of price |
| Market rent vs. lease | Matches lease | 10% below lease |
| Coverage ratio | About 1.20x | About 1.08x before resizing |
The value gap does the first damage. At 75% of the lower appraised value, the loan equals roughly 69% of the price. The down payment effectively moves from about 25% to about 31% of price, even though the contract never changed.
The rent gap does the second. A 10% lower rent opinion takes a 1.20x file to about 1.08x. A smaller loan then trims principal and interest, but taxes and insurance do not shrink, so the ratio recovers only part of the way. Still above 1.00x, but with less room.
Now push the rent opinion 20% below the lease. The same file falls to about 0.96x. Standard programs built around a 1.00x floor would stop there. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted, which usually means a lower LTV and different terms. Options a lender would review include an interest-only period, a larger down payment, or a challenge to the rent opinion. Qualification stays subject to lender guidelines, credit approval, and property review.
One caution on reading this. DSCR compares rent to PITIA only. Clearing 1.00x is not the same as positive cash flow, since repairs, vacancy, management, utilities, and capex sit outside the calculation.
Which Limit Binds First?
On a fourplex with distant comps, three tests apply at once, and the file is capped by whichever one bites hardest.
| Test | What it limits | Distant-comp trigger |
|---|---|---|
| Lower of price or value | Loan base | Conservative value conclusion |
| LTV cap (75%-80% on most purchases) | Loan size | Applied to the lower value |
| Coverage floor (1.00 where select programs start) | Eligibility and pricing tier | Low market rent opinion |
A buyer with a strong credit score and a large down payment can clear the leverage test and still fail on coverage. A buyer with rents far above the payment can clear coverage and still be short on cash to close. A larger down payment lowers the payment and can lift the ratio, but it never erases credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Credit and reserves are separate gates that comps do not touch directly. A 620 score floor exists in parts of the network, most programs want around 660, and 700 or higher opens the strongest leverage tiers. Reserves commonly run around 6 months of PITIA and step up to about 9 months on loans above $1,500,000, with details varying by lender and file.
Where the General Rule Breaks
Rural or distance overlays. Some programs treat a rural designation, or comps beyond a set distance, as an eligibility issue rather than a value input. In that case the file never gets to the arithmetic above. There is no universal definition of rural or population threshold, and it is lender-specific. Ask before ordering the appraisal.
Acreage. Excess land is typically excluded from appraised value, so a property on a larger parcel can appraise below what a buyer expects. Programs often tighten leverage as parcels get bigger.
Income approach weight. Practitioners disagree on how much the income approach helps on 2-4 units. One investor-forum thread describes the appraiser weighing both comps and income, with the lender able to restrict which approach is used. Plan on sales comparison driving value and do not count on the income approach to rescue it.
Five or more units. A fifth unit changes the underwriting category. Five-plus properties are generally underwritten as commercial and valued on income.
Property types not offered. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs. In small towns these types show up often, so confirm the building type before spending on an appraisal.
Short-term rental plans. The 1007 and 1025 rent schedules are built around long-term leases. An appraiser’s rent opinion may not reflect nightly income.
Owner-occupied buyers. Owner-occupants face a different product set. Lendmire’s piece How Much a VA Cash-Out Releases on a Fourplex at Full Value covers that route, which sits outside DSCR.
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.
What to Do Before and After the Appraisal
The appraisal is the commitment point. A little preparation before the order costs less than a reconsideration after it.
Before ordering:
1. Count real fourplex sales. Look for closed sales of four-unit buildings in the town and surrounding market, and note how old and how far away they are.
2. Pull rental evidence for each unit type. Match bedroom counts and unit mix, since mismatched rent comps are a common source of low rent opinions.
3. Ask about program rules. Confirm any rural designation, distance, or acreage overlay and the leverage that applies, before paying for the appraisal.
4. Run coverage on the lower number. Test the file at the lower of lease or market rent, with one unit empty and a trimmed value.
5. Send the package at order. Give the appraiser closed sales, rental listings, and lease copies. Ask for an appraiser who knows the county.
After a low result:
1. Check the report for errors. Look at unit counts, square footage, and condition notes.
2. Request a reconsideration of value. Supply competing sales or listings the appraiser missed, with evidence rather than opinion.
3. Restructure if the value stands. Reduce the loan or bring more cash.
4. Revisit the structure. A lower leverage tier, an interest-only period, or a select-lender path for coverage below 1.00 may apply, subject to lender guidelines.
5. Walk or renegotiate. If the numbers no longer work, a lower price may be the cleanest fix.
If the Number Still Comes In Short
Start with which test failed. A value shortfall is a cash problem, so the choice is more down payment, a lower price, or a smaller loan. A coverage shortfall is a structure problem, so the choice is more equity to lower the payment, a different term structure, or a select-lender path that accepts lower coverage with leverage adjusted. When both fail, the price usually needs to move.
Budget for a reconsideration in advance. It is a routine step on thin-comp files and works when it is supported by specific sales and listings.
Frequently Asked Questions
Is there a maximum distance for fourplex comps?
Not in the appraisal standards DSCR lenders borrow. The test is whether the comps reflect the same market influences as the subject, and the appraiser must explain the choice. A lender or program overlay can set its own distance preference, so ask the program directly.
Does the appraiser use the leases I have in place?
The appraiser forms an independent market rent opinion for each unit. Most programs credit the lower of the signed lease or that market rent, so a lease above market does not raise the ratio.
Can a low value be challenged?
Yes. A reconsideration of value works best with closed sales or competing listings the appraiser missed. If the value stands, the usual responses are a smaller loan or more cash to close.
Will the income approach lift a fourplex value?
Not reliably. Value on 2-4 units is mostly set by sales comparison, and how much weight the income approach gets depends on the appraiser and the lender.
What changes if the building has five units?
It moves into commercial underwriting and income-based valuation, which is a different path from the residential DSCR programs described here.
