The Quick Read: Your maximum loan is the lowest result of several separate tests: a leverage cap applied to the appraised value, a rent-coverage test, loan-size limits, and credit and reserve rules. On a no-cash-out refinance of a duplex, triplex, or fourplex, the leverage cap is usually the most generous of any refinance type.
- A rate-and-term refinance pays off your old loan and returns no cash, so lenders give it more room than cash-out.
- Across Lendmire’s wholesale network, the ceiling on an investment-property rate-and-term refinance reaches 85% of value. That is a ceiling, not a promise.
- Cash-out on a standard rental tops out around 75%. Short-term-rental collateral sits lower.
- Rent still has to cover the new payment, and a typical program starts at a 1.00 coverage ratio.
- Credit score, reserves, loan size, and the appraisal can each pull your number below the cap.
What Counts as Rate-and-Term on a 2-4 Unit?
A rate-and-term refinance replaces your current loan with a new one and puts no cash in your pocket. You change the interest cost, the term, or the loan structure. The new loan covers the payoff, closing costs, and any prepaid items. Nothing else.

If the refinance returns cash to you, it is a cash-out, full stop. That puts you under tighter leverage limits and usually a seasoning clock. Seasoning is the waiting period a lender wants between buying a property and refinancing it.
The classic rate-and-term use is a takeout. You paid for the building with a bridge or hard-money loan, the work is done, and now you want long-term financing. Another is swapping an adjustable loan for a fixed one. A third is a rental that already cash-flows, where you just want a cleaner loan.
A 2-4 unit property fits well because the rent roll is built unit by unit. The appraiser typically completes a small residential income property report with a rent schedule for each door. That schedule drives the coverage number. Agency form numbers (1025 for 2-4 units, 1007 for single-family) are just templates here. DSCR loans are not agency products, and each program decides whether market rent or the signed lease governs.
How Is the Maximum Loan Calculated?
The maximum loan is the lesser of two numbers. The first is the leverage cap times the appraised value. The second is the loan size at which rent still meets the program’s coverage floor. Then loan-size limits and credit and reserve rules can trim it further.
Picture it as a series of gates. Your loan has to clear every one.
1. Value. On rate-and-term, the lender generally works from the appraised value. The cost-based sizing window, where a lender uses the lower of what you paid or the appraisal, matters mostly on cash-out. It can still show up if you bought very recently.
2. Leverage cap. Multiply that value by the program’s cap. On an investment-property rate-and-term refinance, the network’s ceiling is 85%. Real files often land lower, because 2-4 unit properties, condos, and weaker credit can all pull the cap down on specific programs.
3. Coverage. Divide the property’s monthly rent by its monthly PITIA. PITIA is principal, interest, taxes, insurance, and association dues. A typical program starts at 1.00.
4. Loan size. Standard programs run up to $3,000,000. Smaller balances route through select lenders in the network. Above $2,500,000, most of the network holds to 30-year fixed structures.
5. Credit and reserves. A 620 score is the floor in parts of the network. Most programs want around 660. A 700 or better opens the strongest tiers.
Whichever gate gives the smallest answer sets your maximum. Here is the part most borrowers miss: the leverage cap is rarely the gate that bites on a thin rent roll.
One note on the formula. Textbook DSCR, the kind in general finance references, divides net operating income by debt service. Wikipedia’s entry on the debt service coverage ratio gives that version. Residential DSCR programs work from gross rent against PITIA instead. Mixing the two up is a common source of bad math.
Two Limits, One Answer: Which One Binds?
Leverage and coverage are independent tests, and you only borrow the smaller result. A fourplex with fat equity can still be capped by rent. A duplex with strong rent can still be capped by equity. Run both before you assume anything.
Here are three modeled scenarios. These are assumptions for illustration, not market data, and they use percentages and ratios only.
Scenario one: equity-rich, rent-strong. Say your fourplex appraises at 100 units of value. Your payoff is 60% of that. Closing costs and prepaids add about 3% (a modeled assumption). The new loan needs to be about 63% of value. That sits far under the 85% ceiling, and rent covers the payment at roughly 1.3x. Neither gate pinches. The loan is small, the ratio is strong, and the pricing tier is typically better.
Scenario two: leverage-bound. Your triplex has a payoff at 82% of appraised value. Add 3% for costs and you need 85%. That is right at the ceiling. Any appraisal that comes in light pushes you over, and you would have to bring cash to closing or take a smaller loan. Coverage is fine at about 1.15x, but the cap sets the number.
Scenario three: coverage-bound. Your duplex has a payoff at 70% of value, well inside the cap. But taxes and insurance are heavy against modest rents, and coverage lands near 0.90x. Sub-1.00 coverage is available through select lenders in the network, with leverage and terms adjusted. A larger paydown at closing can also lift the ratio, because a smaller loan means a smaller payment.
That third case is the one that surprises people. Equity alone does not qualify you. The strongest files clear both tests: enough equity and enough rental coverage.
Does a 2-4 Unit Get the Same Cap as a Single-Family Home?
Not always. Programs vary, and some set 2-4 unit and condo collateral a step below single-family. Treat the 85% figure as the top of the range on an investment-property rate-and-term refinance, then expect your actual cap to depend on the program, the unit count, your credit, and the appraisal.
That is why a broker who sees many lenders matters here. Across the wholesale network, most programs we place files with land somewhere in the middle of the range for a mid-credit borrower. A few lenders will go to the ceiling for a 700-plus score with solid reserves. The strictest overlays take 2-4 unit collateral down from there. If one lender gives you a lower cap, that is not the market. It is one program.
Here is how the main factors move your number:
| Factor | Effect on your maximum loan |
|---|---|
| Unit count (2 vs 3-4) | Cap can step down on some programs |
| Credit score | 700+ unlocks the strongest tiers |
| Rent coverage | Below 1.00 adjusts leverage and terms |
| Loan size | Larger balances add reserves and rules |
| Collateral type | Short-term rentals sit lower |
What Rolls Into the Loan, and What Turns It Into Cash-Out?
A rate-and-term loan can generally cover your payoff, closing costs, and prepaid items. It should not hand you meaningful cash beyond those. If the loan exceeds the payoff plus costs by more than a lender’s tolerance, the file is treated as cash-out. That means a lower cap and a seasoning clock.
Two practical points come up constantly.
Payoff plus costs can exceed your cap. When that happens, you have three options: bring cash to closing, size the loan smaller, or wait for a stronger appraisal. Some borrowers also try a different program. Rolling costs in is convenient, but it eats into your leverage room.
What you are paying off matters. A hard-money or bridge payoff is the cleanest rate-and-term case, because the money was already spent on the property. A second lien or private loan used for other purposes can blur things. If some of that debt funded something other than the property, a lender may read it as cash-out. Ask before you assume.
On a recent purchase or rehab, the appraisal sets the loan, not your budget or your projected after-repair value. If the appraisal comes in below your hoped-for number, you may be short of the payoff. Plan a cushion.
For the cash-out side of this decision, Lendmire’s guide Investment Cash-Out Refinance LTV Rules for 2–4 Unit Properties lays out how those caps differ.
Credit, Reserves, and Seasoning
Credit and reserves rarely set your maximum on their own. They shift the cap and the pricing tier. Seasoning is the lightest part of a rate-and-term file.
Credit. A 620 score exists as a floor in parts of the network. Most programs want about 660. A 700 or better opens the strongest leverage tiers. At the top leverage tiers, expect the score to matter more than the property.
Reserves. These are liquid funds you hold after closing. They vary by lender, leverage, loan size, and transaction type. Around six months of PITIA is common. Conservative rate-and-term files at modest leverage under $1,500,000 can see reserves waived. Above that size, expect to step up to about nine months.
Seasoning. Rate-and-term is generally more lenient than cash-out, where about six months of ownership is the common expectation. That gap is a big reason investors pick payoff-only when a bridge loan is nearing its end.
Short-term rentals. If the building is an Airbnb-style property, leverage sits lower. Refinance runs around 70% on STR collateral, versus higher ceilings on standard long-term rentals. Expect a 640-plus score, about 12 months of hosting history, and a 1.00 coverage floor on refinances. 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.
Structure. The spine is the 30-year fixed. Select lenders in the network offer 40-year terms and interest-only periods, and ARM structures exist for investors who want them.
Does an LLC Change the Math?
Not the leverage math. Vesting a 2-4 unit in an LLC is generally possible, subject to program terms, and it does not by itself change the cap. Agency investment loans typically bar LLC ownership. DSCR programs generally allow 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. The CFPB’s Truth in Lending reference and the Federal Reserve’s Consumer Compliance Handbook chapter both treat business-purpose credit as generally exempt from consumer-credit rules. That is why your file documents the business purpose and the property’s income, not your paycheck.
A qualifying DSCR file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Entity papers, credit, and a payoff letter round out the package.
What Doesn’t Change With a Bigger Equity Cushion
More equity helps. A larger down payment, or a paydown at closing, lowers the payment and can lift your coverage ratio. But it never erases leverage caps, credit floors, reserve rules, or property eligibility.
Ineligible collateral stays ineligible no matter how much equity you hold. Manufactured homes (single- and double-wide), log homes, and barndominiums are not offered in the network’s DSCR programs.
And a quick myth to retire: a coverage ratio above 1.00 is not positive cash flow. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capital expenses sit outside the calculation. A fourplex can clear the test and still run thin once you add those in. Do your own operating budget before you refinance.
No-ratio is available only through select lenders, generally for borrowers who already own a primary residence.
When the Number Comes Up Short
You have a few moves when your maximum loan falls below the payoff plus costs.
- Pay down at closing. A smaller loan clears the leverage cap and lifts the coverage ratio.
- Wait out the appraisal. If a rehab just finished, a later appraisal may capture more of the improvement. An improvement may support a higher appraised value, depending on comps and underwriter review.
- Try a different program. Caps and overlays differ across the network, and a broker can shop a file across them.
- Extend the structure. Interest-only periods and 40-year terms through select lenders can improve the coverage ratio.
- Consider a sub-1.00 path. It is available through select lenders in the network, with leverage and terms adjusted.
Is a Rate-and-Term Refinance Worth Doing?
It is worth it when the new loan fixes a real problem: a balloon coming due, a short-term loan with a thin margin, or a structure that does not fit your hold. Run a simple break-even. Compare the total cost of closing to the monthly savings or risk reduction you get, and decide whether you hold long enough to recoup it.
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
How much can I borrow on a rate-and-term refinance of a fourplex?
Up to the lowest of your leverage cap, your coverage limit, and program loan-size and credit rules. The network ceiling for an investment-property rate-and-term refinance is 85% of value, though most files land lower. Rent has to cover the new payment too. The calculator on the site gives an illustrative estimate once you enter your numbers.
Can I roll closing costs into the new loan?
Generally yes, within the cap. Payoff, closing costs, and prepaids can usually be financed without the loan counting as cash-out. If those items push you past the leverage cap, you would bring cash to closing or size the loan smaller. Taking meaningful extra cash can reclassify the file as cash-out.
Does the appraisal or my purchase price set the value?
On rate-and-term, the lender generally uses the appraised value. If you bought very recently, some programs size to the lower of cost or appraisal. That window matters mostly on cash-out, so rate-and-term is often the easier route right after a rehab.
What if I own the property free and clear?
Then replacing no debt with a new loan is usually treated as a cash-out, not rate-and-term, because cash comes to you. Cash-out on a standard rental tops out around 75%. Lendmire’s piece How Much Cash a 2–4 Unit Investment Cash-Out Refinance Releases covers that math.
Can I use an LLC on a 2-4 unit refinance?
Generally yes, subject to program terms. The entity does not change the leverage cap, but lenders will want the entity papers and may look at the guarantor’s credit.
