Apartment Investment Property Refinance Loan Finance — The Quick Read: Unit count decides everything. A lender checks this before it even looks at the numbers. A 1-4 unit rental property generally qualifies through a DSCR-style investor loan. That loan is built around the property’s rent. A building of five units or more works differently. It shifts into commercial or federally insured multifamily underwriting. Cash-out and rate-and-term refinances are priced and leveraged as two different transactions. They are not two names for the same thing. Lendmire (NMLS# 2371349) arranges DSCR investor refinancing through a network of wholesale lenders. That network spans 39 states plus Washington, D.C. This applies to investors whose properties sit in that 1-4 unit lane.
Here’s what matters most before diving into the mechanics:

- Federal rules draw a hard line at five units for multifamily purposes — that line, not marketing language, decides which underwriting world applies.
- DSCR-style refinancing is reviewed on the property’s rental income covering the payment, not personal income documentation, subject to lender guidelines.
- Cash-out refinances top out lower than rate-and-term deals across most of the network, and they draw a seasoning expectation most rate-and-term files skip.
- A coverage ratio below 1.00 doesn’t automatically shut the door — select lenders in the network review it, with leverage and terms adjusted.
- Some property types simply aren’t offered through DSCR programs, no matter how strong the rent looks.
Which Lane Is Your Refinance In?
Unit count sorts every apartment refinance before anything else gets underwritten. A duplex, triplex, or fourplex is generally treated as a residential-style investment property. A building with five or more units falls under the federal definition of a multifamily project. 24 CFR § 290.3 defines it as “a project consisting of five or more units that has or had a mortgage…insured under the National Housing Act.” That single line explains a lot. It’s why a fourplex refinance and a twenty-unit apartment refinance look almost nothing alike. The paperwork differs. The timeline differs. The available programs differ too.
Within Lendmire’s network, DSCR-style refinancing is built for that 1-4 unit residential lane. This includes small multifamily properties that sit comfortably under the five-unit line. Once a property crosses into the federal multifamily category, things change. It typically moves into small-balance commercial financing, bank portfolio lending, or federally insured permanent debt. That’s a different underwriting universe, with its own documentation and process. Investors scaling from a fourplex into a larger apartment building should expect that shift. Don’t assume the same rent-schedule approach carries over.
Key Terms Defined
DSCR (debt service coverage ratio): a measure comparing the property’s monthly rent to its monthly housing payment — principal, interest, taxes, insurance, and any association dues, often shortened to PITIA.
PITIA: the full monthly housing obligation used in the DSCR calculation — principal, interest, taxes, insurance, and association dues, if applicable.
LTV (loan-to-value): the loan amount expressed as a percentage of the property’s value or purchase price; lower LTV means more borrower equity in the deal.
Cash-out refinance: a refinance that pays off the existing loan and sends the borrower additional loan proceeds drawn from the property’s equity.
Rate-and-term refinance: a refinance that replaces the existing loan’s structure or terms without pulling any cash out.
Seasoning: the minimum amount of time a lender wants a borrower to have owned or held a property before allowing a certain transaction, most often relevant on cash-out refinances.
Business-purpose loan: a loan made for investment or rental purposes rather than a primary residence, which changes which consumer-protection rules apply to the file.
Why Refinance an Apartment or Investment Property?
Most refinances on investment property happen for one of three reasons. Investors want to pull equity out. Or they want to restructure the loan’s terms. Or they want to reposition the property’s financing to match a new plan for the asset. A rate-and-term refinance can extend or shorten a term. It can move between structures. Or it can simply replace a loan that no longer fits the property’s cash flow. A cash-out refinance converts built-up equity into loan proceeds. An investor can redeploy that money, often toward a down payment on the next acquisition. Lendmire’s breakdown of refinancing to buy another investment property covers this in more depth.
Some investors refinance simply because the property’s rent has grown. That growth changes the DSCR math. A stronger coverage ratio can open better leverage or pricing tiers on the next transaction, even without pulling cash out. Lendmire’s DSCR refinance loan overview covers how that ratio shift plays into refinance eligibility.
How Underwriting Actually Treats the File — Step by Step
Step 1 — Unit count sorts the file first. As covered above, 1-4 units routes to residential-style DSCR underwriting. Five or more units routes to commercial or federally insured multifamily underwriting.
Step 2 — The ratio gets calculated the same way regardless of program. Whether the file is DSCR-style residential or full commercial, the math follows the same idea: income divided by debt service. On the 1-4 unit side, lenders swap in gross rent and the full PITIA payment. That replaces the commercial world’s net operating income and debt service. Lendmire’s guide to how DSCR loans work walks through that calculation in detail.
Step 3 — The appraisal builds the income number the file rests on. For 1-4 unit properties, the appraiser completes a comparable rent schedule. This form is widely known in the industry as a 1007 (single unit) or 1025 (two-to-four units). Non-QM lenders lean on that same rent-schedule naming convention as a shared verification standard. This happens even though DSCR loans aren’t sold to any government-sponsored agency. On the 5+ unit commercial side, underwriting works differently. It uses a full income-and-expense operating statement instead of a rent-schedule form.
Step 4 — Cash-out and rate-and-term are different risk categories. A rate-and-term refinance replaces existing debt one-for-one. A cash-out refinance sends equity out the door as loan proceeds. That’s exactly why it draws tighter leverage industry-wide. Across most of Lendmire’s network, cash-out refinances cap around 75% LTV. That usually comes after about six months of ownership seasoning. Purchase leverage can run higher by comparison.
Step 5 — Business-purpose classification changes the paperwork, not the math. DSCR loans are designed for non-owner-occupied investment properties. They’re business-purpose investor loans. Because of that, they’re reviewed and disclosed differently than a standard owner-occupied mortgage.
What Leverage, Credit, and Reserves Actually Look Like
For the 1-4 unit DSCR lane, most purchase files land between 75% and 80% LTV. Select high-leverage programs reach 85% LTV for borrowers carrying roughly a 700-plus credit score. Cash-out refinances generally cap around 75% LTV across the network. Roughly six months of seasoning is expected as a baseline.
| Factor | Typical Range Across the Network |
|---|---|
| Purchase LTV | 75%-80%, up to 85% on select programs |
| Cash-out refinance LTV | Up to 75% typical, ~6 months seasoning expected |
| Coverage ratio | 1.00 is a starting floor on select programs |
| Credit score | 620 floor in parts of the network; 660 common; 700+ unlocks top leverage |
| Reserves | Roughly 6 months PITIA typical; ~9 months above $1,500,000 |
| Loan size | Roughly up to $3,000,000 on standard programs |
A DSCR of 1.00 means rent covers the payment dollar-for-dollar. It does not mean the property is generating positive cash flow. Repairs, vacancy, property management, utilities, and capital expenses all sit outside that calculation entirely. Reserve requirements aren’t a single fixed number. Conservative rate-and-term files at modest leverage under $1,500,000 sometimes see reserves waived. Larger loans above that threshold typically step up to about nine months of PITIA. Larger loan balances also tend to push term structure toward a 30-year fixed above roughly $2,500,000. That’s where the network’s appetite for adjustable or interest-only exceptions narrows. A handful of states carry purchase-LTV overlays. Connecticut, Florida, Illinois, and New Jersey are among them, generally capping near 75%. Overlay-state deals are often capped around $2,000,000 as well.
A larger down payment lowers the monthly obligation and can lift the coverage ratio. But it never overrides a leverage cap, a credit floor, a reserve requirement, or property eligibility. The strongest files clear both tests at once. They have enough equity in the deal, and enough rent to comfortably cover the payment. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
DSCR vs. Bank and HUD-Insured Multifamily Financing
DSCR-style investor loans and traditional bank or agency financing solve for different borrowers. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines. A conventional bank loan works differently. It weighs the borrower’s personal income, traditional personal-income documentation, and debt-to-income ratio.
Once a property crosses the five-unit threshold, federally insured permanent financing becomes available through multifamily channels. That’s a genuinely different pipeline. It runs through lenders participating in that program and underwrites to stabilized operating income rather than a rent schedule. One version of that channel exists purely to adjust rate or term. It’s barred by statute from any cash-out component. An investor whose real goal is pulling equity needs to confirm upfront whether the tool in front of them can even do that. Confirm this before spending months in the process.
| Path | Unit Count | Cash-Out Available? |
|---|---|---|
| DSCR-style residential | 1-4 units | Yes, generally up to 75% LTV |
| Small-balance commercial / bank | 5+ units | Varies by lender |
| Federally insured refinance-only programs | 5+ units | No — statutorily barred on that specific tool |
Cash-Out vs. Rate-and-Term: The Real Difference
Picture an investor holding a fourplex at 65% LTV after several years of rent growth and appreciation. A rate-and-term refinance on that property simply swaps the existing loan for new terms. No proceeds change hands. Leverage can run to the higher end of the purchase-style range. A cash-out refinance on the same fourplex works differently. It caps lower, around 75% LTV across most of the network. That’s because equity is leaving the deal as loan proceeds rather than staying parked in the property.
That gap exists industry-wide, not just at Lendmire. Lendmire’s cash-out refinance overview and investment property refinance page break down how leverage, coverage ratio, and seasoning interact on each type of transaction. Investors weighing a cash-out draw against a smaller equity need sometimes look at an investment-property HELOC instead. Those lines cap at $500,000 total across the network, with no tier above that ceiling.
A brokerage that places files across many lenders sees this pattern constantly. Apartment refinance files often come in strong on appreciation but thin on documented rent. Those files often stall at the appraisal stage, not the credit stage. The fix is usually a fresh, defensible rent schedule before the file goes to underwriting — not a bigger down payment.
Where the General Rule Breaks — Edge Cases
Mixed-use buildings don’t blend income the way owners expect. On the 1-4 unit residential side, ground-floor commercial space is generally excluded from the standard rent-schedule methodology. Only the residential units carry into the DSCR calculation. A small mixed-use building’s commercial rent roll doesn’t simply flow into the residential income number.
Short-term rental income breaks the standard rent-schedule assumption. The market-rent schedule appraisers use for 1-4 unit properties was built around long-term lease comparables, not nightly-rate income. That’s why STR documentation varies meaningfully by lender, rather than following one uniform rule. Short-term rental rules can also vary by city, county, HOA, and property type. Investors should confirm local rules before relying on projected rental income.
A 1031 exchange running near a refinance has its own clock, independent of the loan. An investor refinancing an apartment property around the same time as a like-kind exchange has to respect a firm federal deadline. That deadline has nothing to do with lender processing. The IRS gives 45 days from the date the relinquished property sells to identify replacement properties in writing. The full exchange must close within 180 days. A cash-out refinance completed at the wrong moment relative to that window can create tax exposure. That exposure is entirely separate from the loan itself. Tax treatment can depend on how 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 or exchange strategy.
The conventional financed-property ceiling is why many investors move to DSCR-style refinancing at all. Once an investor has maxed out the number of conventionally financed properties allowed under standard agency guidelines, DSCR-style loans become the practical path forward for continued growth. They’re underwritten to the property rather than to a personal-loan count.
Sub-1.00 Coverage and No-Ratio Options
A coverage ratio under 1.00 doesn’t automatically disqualify a refinance. Programs below that 1.00 floor are available through select lenders in the network. Leverage and terms get adjusted to offset the weaker coverage. That usually means lower LTV or stronger compensating factors elsewhere in the file. No-ratio qualification is a narrower path still. It’s available only through select lenders. It’s generally reserved for borrowers who already own a primary residence. It doesn’t come with the same pricing or leverage as a fully qualifying file. Neither structure is guaranteed on any given property. Both are reviewed subject to lender guidelines, credit profile, and property review.
Some property types sit outside DSCR programs entirely regardless of coverage ratio. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered through the network’s DSCR programs, full stop.
What the Investor Decision Looks Like in Practice
Start with unit count, then layer in the building’s condition. A stabilized 1-4 unit property with solid, verifiable rent is the cleanest DSCR refinance candidate. The file leans on the rent schedule and the coverage ratio. Pricing tiers open up as credit score and equity improve. A property with deferred maintenance, below-market rents, or partial vacancy tells a different story. The appraised rent schedule may come in conservative until the units are re-leased at market rates. That can compress the coverage ratio right when an investor wants to refinance.
For anything crossing into the five-unit-plus category, the decision shifts entirely. The investor is now choosing between small-balance commercial debt, bank portfolio financing, or a federally insured permanent loan. Each option has its own documentation burden and process. Lendmire’s complete DSCR loans guide is a useful starting point for investors still sorting out which lane their next refinance actually belongs in. Lendmire’s broader apartment investment property refinance resources cover the surrounding program details in more depth.
Rental vacancy has been trending upward nationally. That tends to push appraisers toward more conservative market-rent conclusions. This dynamic flows directly into the coverage ratio used to size any refinance. An investor refinancing into a softer rental environment should expect the rent-schedule number, and therefore the proceeds available, to reflect that caution rather than a peak-market assumption.

Frequently Asked Questions
Can I refinance a fourplex the same way as a 20-unit apartment building?
No. A fourplex generally qualifies through a residential-style DSCR refinance built around a rent schedule. A 20-unit building works differently. It falls under the federal multifamily definition and moves into commercial or HUD-insured underwriting built on a full operating statement instead.
What’s the real difference between a rate-and-term and a cash-out refinance on an apartment property?
A rate-and-term refinance replaces the existing loan without pulling equity out. A cash-out refinance sends loan proceeds to the borrower from the property’s equity. Cash-out refinances carry tighter leverage across most of the network, capping around 75% LTV. They typically expect around six months of ownership seasoning first.
Does refinancing an apartment building affect a 1031 exchange I’m running?
It can. The IRS 45-day identification deadline and 180-day exchange period run on a fixed clock, independent of any lender’s process. Timing a cash-out refinance around those dates without careful planning can create tax exposure that has nothing to do with the loan itself.
Can I still refinance if my coverage ratio comes in below 1.00?
Sub-1.00 coverage doesn’t automatically close the door. Select lenders in the network review those files, typically adjusting leverage and terms to offset the weaker ratio. Outcomes depend on the borrower’s credit profile, the property, and program guidelines at the time of review.
What happens to my refinance options once a rental property crosses five units?
Once a property hits the five-unit federal multifamily threshold, standard residential-style DSCR rent-schedule underwriting no longer applies. The refinance instead moves into small-balance commercial lending, bank portfolio debt, or federally insured multifamily programs. Each option has its own documentation and process.
