Apartment Investment Property Refinance — The Quick Read: Refinancing an income property follows one of two rulebooks. Which rulebook applies depends on how many units the property has. A duplex, triplex, or fourplex usually refinances against its rent schedule. Lenders review it the same way they review any rental under a DSCR loan — they check property income against the payment. A true apartment building with five or more units works differently. It usually moves into commercial or agency underwriting. That underwriting is built around net operating income, not a simple rent check. Get this fork wrong at the start, and every number after it goes wrong too — leverage, paperwork, and timeline expectations all shift.

Key Takeaways
- Unit count decides the underwriting path before anything else: 1-4 units generally run on a residential-style rent schedule; 5+ units move into commercial, agency, or HUD-insured multifamily underwriting.
- Cash-out refinances and rate-and-term refinances are not the same product with different names — cash-out gets a lower leverage ceiling because the borrower is pulling equity out, not just replacing debt.
- On most DSCR files, cash-out leverage tops out around 75% loan-to-value, while purchase and rate-and-term deals can run higher.
- A coverage ratio of 1.00 — rent covering the full monthly obligation — is where some programs start, not a universal requirement, and stronger ratios open better leverage.
- Ownership seasoning, reserve requirements, and prepayment structure all shift the math well before a rate ever enters the conversation.
Key Terms Defined
DSCR (debt-service coverage ratio): This is a coverage ratio. It divides the property’s monthly rent by its monthly debt payment. That tells you if the rent covers the payment.
PITIA: This is the full monthly bill on a property. It includes principal, interest, taxes, insurance, and any homeowners association dues. DSCR gets measured against this number.
LTV (loan-to-value): This is the loan amount shown as a percentage of the property’s appraised value. A lower LTV means more equity sits in the deal.
Cash-out refinance: This is a new, bigger loan. It pays off the old mortgage and hands the borrower the leftover cash.
Rate-and-term refinance: This refinance swaps out the old loan without pulling extra cash. It usually qualifies for higher leverage than a cash-out.
Seasoning: This is the minimum time a lender wants an investor to own a property before funding a cash-out refinance on it.
Non-QM / business-purpose loan: This is a loan made to an investor for a rental property, not a primary home. Lenders review it under a different set of rules than a standard owner-occupied mortgage.
NOI (net operating income): This is a property’s income after operating costs. Commercial and agency lenders use this number instead of a residential rent schedule.
Where Does Your Property Fall — 1-4 Units or 5+?
This is the biggest fork in the whole topic. Lenders decide it before they even look at the borrower’s credit. A 2-4 unit property gets treated as residential for refinance purposes. A 5+ unit building does not. Full stop.
On the small side, appraisers write down market rent using the industry-standard Form 1025, Small Residential Income Property Appraisal Report. Lenders across the industry point to this format for 2-4 unit rent work, even outside agency lending. That rent number, weighed against the monthly payment, becomes the coverage ratio a DSCR file is built on.
Cross into five or more units and the whole paperwork approach changes. Instead of a rent schedule, the file runs on a commercial appraisal and net operating income. It often moves toward agency, bank, or federally-insured multifamily financing instead of residential-style DSCR. HUD, for example, insures purchase and refinance deals on existing multifamily projects through its Section 207/223(f) program. That’s a completely separate path from anything a residential rent schedule produces. It has its own timeline, its own entity rules, and often its own non-recourse structure.
| Property Size | Ownership | Underwriting Basis | Typical Path |
|---|---|---|---|
| 1-4 units | Individual or LLC | Rent schedule vs. full monthly payment | DSCR (non-QM) |
| 1-4 units, owner occupies one unit | Individual | Personal income (W-2/tax return) | Conventional |
| 5+ units | Entity | Net operating income vs. annual debt service | Agency, bank, or HUD-insured |
| 5+ units, cash-out sought | Entity | NOI-based; non-recourse common in HUD structures | Agency/bank; some HUD paths are rate-and-term only |
Lendmire is a DSCR-focused mortgage broker (NMLS# 2371349). It arranges the small end of that table — 1-4 unit residential-style investment refinances — through a wholesale network spanning 39 states plus Washington, D.C. That’s a 40-market footprint. True apartment-building deals at 5+ units usually live outside that lane. They route toward the commercial and agency side instead. Lendmire’s complete DSCR loans guide walks through how the residential side of that qualification actually works.
How Underwriting Actually Treats the File
The order of steps matters more than most investors expect. Each step narrows what the next step can do.
Step 1 — classify the transaction. A rate-and-term refinance replaces the old loan without pulling cash out. It typically opens up higher leverage. A cash-out refinance pulls equity out as cash. Lenders underwrite it to a tighter ceiling — commonly around 75% LTV on most files across the network. Why the tighter cap? The borrower walks away with money instead of just swapping one loan for another. This distinction sets the biggest possible loan size before anyone even looks at the borrower.
Step 2 — document the income. On the residential side, the appraiser confirms market rent using the standard rent-schedule format. They cross-check it against any actual lease. A vacant unit doesn’t automatically kill a file. The appraiser’s market-rent estimate can stand in for actual lease income in many cases. If a signed lease runs well above what the appraisal supports, expect the lender to ask for more proof — bank deposits, a certified rent roll, or extra lease paperwork — instead of just taking the higher number.
Step 3 — calculate the coverage ratio. On a 1-4 unit file, that’s rent divided by the full monthly payment. On a commercial or agency file, it’s annual NOI divided by annual debt payments — a related idea, but a different math entirely. Across commercial banking generally, a coverage requirement in the 1.15-1.35 range is common, according to a summary of debt-service coverage ratio standards. That’s noticeably tighter than where residential-style DSCR programs often start.
Step 4 — size the loan. Take the appraised value. Apply the program’s LTV ceiling. That gives you the biggest new loan possible before payoff and closing costs come out. On cash-out deals in Lendmire’s network, that ceiling generally sits around 75% LTV. Purchase and rate-and-term files can run higher — often 75%-80%, with select high-leverage programs reaching 85% LTV for borrowers with a 700+ credit score.
Step 5 — check seasoning. Most lenders in the network want to see roughly six months of ownership before funding a cash-out refinance. Rate-and-term refinances tend to be more flexible on this point.
Step 6 — lock the prepayment structure. DSCR loans are business-purpose investor loans, not consumer mortgages. Lenders review them differently from a standard owner-occupied refinance. They generally fall outside the disclosure timelines that apply to owner-occupied lending. That business-purpose label is also why many non-QM notes build in a step-down prepayment structure. This structure runs longer than what a homeowner would ever see on a primary-residence loan. The exact schedule varies by lender and by how the loan is priced.

What Loan Structures Actually Exist Here?
The 30-year fixed is the backbone of most residential-style DSCR refinances. But it’s not the only option. Select lenders in the network also offer 40-year terms and interest-only periods. These help investors who want lower payments in the early years. Adjustable-rate structures exist too, for those who plan a shorter hold. Loan sizes on standard programs generally run up to about $3 million. Above roughly $2.5 million, the network tends to stick with 30-year fixed structures instead of the more flexible options.
Credit requirements move on a sliding scale. A 620 floor exists in parts of the network. But most programs want something closer to 660. A 700+ score unlocks the strongest leverage tiers. Reserve requirements move with loan size and leverage too. Reserves commonly run around six months of PITIA. They’re sometimes waived on conservative rate-and-term files under roughly $1.5 million. They step up to around nine months on larger loans.
Short-term rental income gets its own lane. Lenders don’t treat it like a standard lease. Purchase leverage on STR-backed files generally tops out at 75% LTV. Refinance and cash-out leverage run closer to 70%. Lenders typically want a 700+ score, roughly twelve months of hosting history, and a coverage ratio clearing 1.00 before they’ll lean on that income. 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 at all.
Some investors don’t want to touch their first mortgage. For them, an investment-property HELOC is worth a look. But the cap on those lines is $500,000 total, with no higher tier for larger portfolios. That makes a HELOC a supplement for smaller equity pulls. It’s not a substitute for a full cash-out refinance on a larger holding.
Not every property qualifies for DSCR financing, no matter the unit count. Manufactured homes — single- or double-wide — along with log homes and barndominiums fall outside these programs entirely. That’s a property-eligibility rule. It’s not a case where the file is simply “harder” to place.
Investors weighing DSCR against a standard bank refinance should know the two run on completely different logic. DSCR looks at what the property earns. Conventional financing looks at the borrower’s personal income and debt. Lendmire’s broader comparison of the two paths goes further into that difference.
Where the General Rule Breaks
Every rule above has an edge case. And the edge cases are exactly where investors get surprised.
The 4-unit/5-unit cliff is not negotiable. A six-unit building next door to an identical-looking fourplex does not qualify the same way. One goes through a residential rent schedule. The other exits into commercial or HUD/agency underwriting with an entirely different appraisal method, timeline, and set of entity rules. Investors shopping a building at exactly the line should confirm unit count before assuming a program fits.
Not every “refinance” is built to release cash. In HUD’s healthcare-linked multifamily programs, borrowers can’t receive any cash proceeds at all. The refinance exists purely to lower cost and fund repairs, not to pull equity. It’s a good reminder that “refinance” doesn’t automatically mean “equity out,” even in federally-backed multifamily lending.
Coverage below 1.00 isn’t an automatic dead end — but it isn’t the standard either. A handful of lenders in the network will look at coverage below 1.00. They adjust leverage and terms to compensate for the weaker ratio. No-ratio structures, where the coverage number isn’t evaluated at all, aren’t part of these programs. If a file needs one, it’s outside this lane entirely. Where 1.00 does apply as a threshold, it’s a floor for specific programs, never a universal standard. Stronger ratios generally buy better leverage and pricing.
Mixed-use buildings with both long-term and short-term units are a real category, not a disqualifier. A small apartment building where some units run as standard leases and others run nightly can still be evaluated. But each income type typically gets documented and verified on its own, not blended into one number.
Certain states carry their own overlays. Purchases in Connecticut, Florida, Illinois, and New Jersey generally cap closer to 75% LTV even where the national ceiling runs higher. Overlay-state deals often cap loan size around $2 million regardless of the property’s value. An investor running the same numbers in an overlay state should expect a tighter ceiling than the network’s general guidance suggests.
What the Refinance Decision Actually Looks Like
Run the numbers on a fourplex an investor has owned for a little over six months. Say it’s now worth meaningfully more than the original purchase price. A cash-out refinance on that property is capped around 75% LTV on most files in the network. Use a modeled rent figure against the full monthly payment. If the resulting coverage lands around 1.25x, that file clears comfortably. Lenders still check reserves and credit, but the coverage math isn’t the sticking point. If the same file lands closer to 1.05x instead, it can still work. But the lender leans harder on reserves and credit score to offset the thinner margin.
That’s the practical trade every investor is actually weighing on a refinance: how much equity to pull, against how much coverage cushion is left over. Pull the maximum allowed and the ratio tightens. Pull less and the ratio loosens — but so does the capital available for the next deal. Files in markets with tighter apartment vacancy tend to support stronger rent for lender review. National apartment occupancy has been recovering some lost ground as new supply has slowed, according to Apartment List’s national rent data. Softer-occupancy conditions, on the other hand, can pressure the rent figure used for lender review, even on a property with a strong track record.
This is also where the recycle-capital strategy runs into a hard ceiling. Many investors refinance, pull equity, then buy the next property. Because cash-out leverage tops out around 75% LTV on most files regardless of credit profile, that ceiling applies on every cycle — not just the first one. Lendmire’s guide on using a cash-out refinance to buy another investment property breaks down how that recycling math plays out over multiple properties.
DSCR lending overall has grown into a much larger share of investor financing in recent years. Volume in the category grew more than 50% year over year at one point. It surpassed bank-statement lending to become the largest slice of non-QM production, according to Scotsman Guide. That growth is exactly why more lenders in the network now offer variations that weren’t common a few years ago — sub-1.00 exceptions, extended terms, STR-specific programs.
One pattern shows up again and again on files with heavy STR concentration in the mix. Rent assumptions based on standard long-term leases often come in tight. But the same property often clears comfortably once trailing twelve-month short-term rental income gets documented properly. The stronger files pull that history from a third-party revenue platform or verified statements, rather than a rough guess. They run the numbers both ways — long-term and short-term — before deciding which income basis to submit.
Tax treatment can depend on how refinance proceeds are used and how the property is titled. Investors should keep clear records and speak with a qualified tax professional before relying on any deduction. And for properties titled in an LLC or similar entity, refinance eligibility and paperwork requirements run a bit differently than for an individual borrower, subject to program terms.

Frequently Asked Questions
Can I refinance an apartment I already own outright, with no existing mortgage?
Yes — lenders typically treat this as a cash-out or rate-and-term refinance, depending on how much of the appraised value the new loan represents. It still runs through the same unit-count fork as any other refinance. A free-and-clear 1-4 unit property generally gets reviewed on whether rental income covers the payment, subject to lender guidelines, the same as a leveraged one.
Do I need to show personal income to refinance a rental property?
Not on a standard DSCR file. Qualification runs primarily on the property’s rental income covering the payment, not traditional personal-income paperwork, subject to lender guidelines. That changes if the property is owner-occupied in part — that shifts the file toward conventional underwriting and personal income documentation instead.
How soon after buying an apartment building can I refinance it for cash out?
Most lenders in the network want to see roughly six months of ownership before funding a cash-out refinance. Rate-and-term refinances, which don’t pull equity out, tend to have more flexibility on that seasoning window.
Why does my apartment refinance get a lower loan-to-value than a house I refinanced before?
Investment property gets priced and structured more conservatively than an owner-occupied home. Cash-out transactions specifically get capped tighter than rate-and-term ones — commonly around 75% LTV on most DSCR files. A 5+ unit building adds another layer, since it often moves into commercial or agency underwriting with its own separate leverage rules.
What happens if my apartment’s rent doesn’t cover the full payment?
A handful of lenders in the network will still look at the file. They typically use lower leverage or other adjustments to offset the weaker ratio. That’s different from a no-ratio loan, which isn’t part of these programs at all. Where coverage does clear 1.00, that’s a floor for specific programs rather than a universal requirement — and stronger coverage generally unlocks better leverage.
If you’re weighing a refinance on a rental property or a small apartment building and want to see how the numbers actually work, Lendmire can help compare DSCR loan options based on the property’s income, your credit profile, target leverage, and what you’re trying to accomplish with the proceeds.
