The Quick Read: A DSCR lender runs two tests on your fourplex, one on value and one on rent, and funds the smaller loan that results. Then it subtracts your old payoff, costs, and any required reserves, and what is left is your cash. Equity alone never sets the number.
- The value test: appraised value times the cash-out leverage cap, which tops out around 75% LTV on a standard rental across most of the network.
- The rent test: the rent used for review, divided by the coverage floor, sets the largest payment the building can carry. The loan is back-solved from that payment.
- The smaller loan wins. Deep equity with thin rent gets cut by the rent test. Strong rent with thin equity gets cut by the value test.
- Net cash is smaller than gross equity. Payoff, closing costs, prepaids, reserves, and any prepayment charge on the old loan all come out first.
- Coverage is not cash flow. Clearing the ratio says nothing about repairs, vacancy, or management. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
Why Is a Fourplex Sized as One Property?
A fourplex is one building with one loan and one payment. The lender adds up the rent from all four units and compares the total to a single monthly obligation. That obligation is PITIA: principal, interest, taxes, insurance, and any association dues.

Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
PITIA is the whole monthly bill on the building, and the coverage ratio (DSCR) is rent divided by that bill. A ratio of 1.00 means rent equals the bill. A ratio of 1.25 means rent is 25% above it.
Pooling units is why small multifamily often shows stronger coverage than a single-family rental at a similar price. Four tenants share one tax bill, one insurance policy, and one mortgage. One vacant unit hurts less than a vacant house does, though it still hurts.
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 file qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Credit, reserves, and the borrower or entity still get reviewed.
Unit count matters. Two to four units sit in the residential-style lane described here. At five units and up, lenders move to commercial-style underwriting with a different formula, usually based on net operating income. A fourplex is the top of the easy lane.
If you live in one of the four units, the file leaves the DSCR lane entirely. These programs are for non-owner-occupied property. A building that is legally a triplex but marketed as a fourplex is valued and tested as a triplex.
Key Terms Defined
- Cash-out refinance: a new loan that pays off the old one and returns the difference to you as cash.
- LTV (loan-to-value): the loan amount divided by the property’s appraised value.
- DSCR: monthly rent used for review divided by the monthly PITIA.
- PITIA: principal, interest, taxes, insurance, and association dues combined.
- Seasoning: the waiting period after you take title before a lender sizes cash-out on appraised value.
- Reserves: liquid funds, counted in months of PITIA, that you must hold after closing.
- Net proceeds: what actually reaches you after payoff, costs, and holdbacks.
The Sizing Sequence, Step by Step
Here is the order a lender works through. Run it in this order on your own building and you will land close to the real number.
1. Classify the transaction. Cash-out, with the building leased and non-owner-occupied. Standard rental collateral and short-term-rental collateral follow different ceilings.
2. Set the value basis. Usually that is the appraised value. If you bought recently, it may be the lower of value and documented cost.
3. Set the rent. This is the rent the lender uses for review, not the rent you hope for.
4. Run the value test. Appraised value times the cash-out cap. Across most of the network, that cap is 75% LTV on a standard rental. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
5. Run the rent test. Divide the review rent by the coverage floor to get the maximum payment. Then work backward from that payment to the loan that produces it.
6. Take the smaller loan, then subtract. Payoff, closing costs, prepaids, reserves, and any prepayment charge on the old loan come out of it.
The rent test is the step most investors never see. A larger loan means a larger payment, so coverage drops as the pull grows. At some loan size, coverage hits the floor and the lender stops there, no matter how much equity is left.
How Does the Appraisal Set Value and Rent?
The appraisal gives the lender two numbers. One is the as-is value, which is the bottom of the LTV math. The other is the appraiser’s opinion of market rent, which feeds the top of the DSCR math.
For a two- to four-unit building, appraisers typically use Form 1025, the small residential income property report. Fannie Mae’s Selling Guide lists it for two- to four-unit properties and ties the one-unit rent schedule, Form 1007, to single-family investment homes. Fannie Mae’s form itself is designed for two- to four-unit properties, including those in a planned development.
That is a brief contrast and nothing more. Agency rules on when each form is required do not govern DSCR files. The form names carry over because appraisers already know them. The rest of the sizing logic here comes from how programs in the network actually work.
What matters is that Form 1025 captures rent unit by unit, not as one blended number. The lender sees which units are leased, at what rent, and what the appraiser thinks each should rent for.
Which Rent Counts: Lease or Appraisal?
It depends on the program. Many programs use the lower of the lease rent and the appraiser’s market rent. A few will use market rent on a vacant unit. The strictest overlays want a signed lease before they count a unit at all.
Here is where fourplexes split from houses. Say you own four units, three leased and one empty. One lender may count the empty unit at appraiser market rent. Another may count only the three leased units. The same building can show a noticeably different ratio between those two treatments, and that can change the loan size.
Mixed leases create a similar wrinkle. Older tenants on below-market leases pull the lease number down. Under a lower-of rule, your legacy rents hold the coverage back even when the appraisal says the building could rent for more.
Use the rent the appraiser can support, not the listing rent or the number you hope to reach. An appraisal that supports less rent than you expected can shrink the loan or sink the approval.
Three Fourplexes, Three Different Binding Tests
These are modeled assumptions, not market data. The point is to see which test binds. Each building is appraised at its own value, and the figures below are shares of that value.
| Profile | Existing loan | Value test (75% LTV) | Rent test supports | Binding test |
|---|---|---|---|---|
| Strong rent, modest equity | 55% of value | 75% | About 85% | Value |
| Thin rent, deep equity | 35% of value | 75% | About 50% | Rent |
| Thin on both | 70% of value | 75% | About 68% | Rent, and no cash |
Building one has rent to spare. The value cap governs. Gross cash is the gap between 75% and the 55% payoff, roughly 20% of value, before costs.
Building two has plenty of equity but soft rent. The value cap would allow 75%, but the rent test stops the loan near 50%. Gross cash is only about 15% of value, far less than the equity suggests. Many owners are surprised by this one.
Building three is thin on both. Its existing loan is already 70% of value, so equity is modest, and its rent supports only about 68%. The loan the rent supports is below the existing payoff. There is no cash-out to be had, and the owner may do better with a rate-and-term refinance or by waiting for rents to rise.
The lesson: equity tells you the ceiling on one side, and rent tells you the ceiling on the other.
What Comes Off the Gross Number?
Gross cash is not net cash. Several items come out before a dollar reaches you:
- Payoff of the existing loan, including accrued interest.
- Closing costs and prepaids, such as the appraisal, title work, and escrow deposits for taxes and insurance.
- A prepayment charge on the old loan. Most DSCR loans carry one, often stepping down over several years. Refinancing inside that window cuts net cash. Some programs trade a lock-in period for better terms. No-penalty options exist, usually at a cost elsewhere.
- Reserves. Programs commonly want about 6 months of PITIA on hand, and about 9 months on loans above $1,500,000. Whether cash-out proceeds count toward that varies by lender, so ask before you plan around it.
Add these up before you decide a pull is worth it. A 75% LTV cap does not mean you get 25% of value in cash. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Why Does the Pull Change Your Ratio?
Take the same building and pull three different amounts. A small pull leaves the payment light and coverage comfortable. A mid-size pull moves coverage toward the floor. A maximum pull may push it right to the edge, or past it.
This is why a smaller pull can be the smarter move. It can raise coverage, protect your reserves, and open better leverage and terms. Stronger ratios generally earn stronger terms, so a borrower weighing a fourplex refinance may do better by not pulling the very most.
It is a genuine tradeoff. A bigger pull funds the next purchase sooner, though it leaves you less cushion if a unit goes vacant. A smaller pull is safer, but it may not fund the deal you are chasing. Test the ratio on the new payment, with the rent the appraiser supports, before you commit.
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.
Gates Outside the Math
Passing both tests is not enough. A file also has to clear a handful of gates, and the table shows how they usually work across the network.
| Gate | What programs typically expect |
|---|---|
| Seasoning | About 6 months of ownership, measured from title recording |
| Credit | A 620 floor exists in parts of the network; most want around 660; 700+ unlocks the strongest leverage |
| Coverage floor | 1.00 is where select programs start |
| Reserves | About 6 months of PITIA; about 9 above $1,500,000 |
| Loan size | Up to $3,000,000 on standard programs |
| Vesting | Individual or LLC, subject to lender program eligibility |
Inside the seasoning window, many programs size on the lower of appraised value and documented cost. This is the bottleneck for investors who buy, renovate, and refinance in a hurry. Plan the timeline around it.
On coverage: 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Eligibility under either path depends on the borrower, the property, and the lender.
Above $2,500,000, the network generally holds to 30-year fixed structures. Extended terms and interest-only periods are available through select lenders for smaller loans.
Credit matters here beyond a pass-fail line. A stronger score can mean more leverage on the same building.
Lenders also review each building on its own. A strong fourplex does not rescue a weak one in the same portfolio. If you hold the property in an LLC, cash goes to the entity, subject to program terms.
Short-term-rental collateral follows tighter rules. Cash-out on a short-term rental tops out around 70% LTV, versus 75% on a standard rental. Expect a 640+ 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. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Manufactured homes, log homes, and barndominiums are not offered on these DSCR programs.
Where the General Rule Breaks
A few cases bend the two-ceiling model.
- Appraised rent comes in light. If your rent schedule comes up short, ask whether a lender has a sub-1.00 option. Select lenders in the network offer one, with leverage and terms adjusted. Pricing and leverage shift, so compare the offers.
- No-ratio structures. They are available only through select lenders, generally for borrowers who already own a primary residence. Treat them as a special path, not the default.
- Value falls short. A low appraisal shrinks the value test. Model the downside before you order it.
- Five or more units. The formula changes to commercial-style underwriting.
- Prepayment window. Cash-out too soon on a loan with a penalty can eat much of the gain.
- Higher coverage is not a free pass. Stronger coverage may help pricing and leverage, but it never erases the 75% cash-out cap, the credit floors, the reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
Fourplex Versus a House
A fourplex does not automatically release more cash than a house. The same percentage cap applies to a bigger value, so the dollar room can be larger. But four units mean more leases, a more detailed rent schedule, and more documentation.
| Factor | Single-family | Fourplex |
|---|---|---|
| Rent evidence | One lease or one rent opinion | Unit-by-unit schedule |
| Vacancy effect | All or nothing | One unit of four |
| Paperwork | Lighter | Heavier |
Pooled rent is the fourplex’s edge. The extra paperwork is its cost.
Common Sizing Mistakes
- Treating equity as cash. Costs, payoff, and reserves come out first.
- Using listing rent. Lenders want rent the appraiser can support.
- Sizing on value alone. The rent test often binds first.
- Reading 1.00 as profit. DSCR compares rent to PITIA only. Repairs, vacancy, management, utilities, and capex sit outside the calculation, so run your own operating budget.
- Ignoring the old loan’s penalty. It can quietly cut your net.
- Pulling the maximum. A smaller pull often leaves a healthier file.
- Assuming the program won’t change. Leverage and overlays shift with lender appetite, and every file is underwritten individually.
Before You Apply: A Short Checklist
Gather the appraisal-ready rent schedule, current leases for occupied units, the payoff statement on your existing loan, insurance and tax figures, entity documents if the building is in an LLC, and proof of reserves. Then model three things: a lower appraisal, a lower rent, and a smaller pull.
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 cash can I pull from a fourplex?
It depends on the smaller of the value-side and rent-side loans, less your payoff and costs. Across most of the network, cash-out on a standard rental tops out around 75% LTV, but rent often cuts it lower. Treat the cap as a ceiling, not a promise.
Which test usually binds first, value or rent?
Rent binds first when equity is deep and rents are soft. Value binds first when rents are strong and equity is modest. Run both before you assume either, because the building decides.
What if I live in one of the units?
Then the property is owner-occupied, and DSCR programs do not apply. These loans are for non-owner-occupied investment properties. Other financing paths exist for house-hackers, and the right one depends on your profile.
How long do I need to own the building?
Most programs in the network expect about 6 months from title recording before they size cash-out on appraised value. Inside that window, sizing often uses the lower of value and documented cost.
Does one vacant unit hurt my ratio?
It can hurt the ratio. Some programs count the vacant unit at appraiser market rent, others count leased units only. The treatment changes the ratio, so ask how a lender handles vacancy before you apply.
