The Quick Read: It depends on equity at today’s value, because a cash-out refinance on a standard rental typically tops out at 75% of what the lender appraises the property for as it stands now, and your net cash is that loan minus your existing payoff and closing costs, with no credit for the addition or ADU you have not built. The rent on the property as it exists today also has to carry the new, larger loan. Whichever limit is lower decides your budget.
- Formula: net cash = new loan, minus existing payoff, minus closing costs, minus any reserves you must fund.
- Value test: the new loan is capped at about 75% LTV on a standard rental, measured on the lender’s as-is appraisal.
- Rent test: DSCR (debt service coverage ratio) on the existing rent typically needs to reach about 1.00 or better, and the loan shrinks until it does.
- Clock test: most programs in the network expect about 6 months of ownership, counted from the recorded deed, before they size on appraised value.
- Reserves: expect to hold about 6 months of PITIA, and the cash you pull out at closing is not what satisfies that requirement.
Program terms are subject to lender guidelines, and none of this is a commitment to lend.

What Is the Cash-Out Formula, and Why Doesn’t the New Unit Count?
The formula is simple: new loan, minus payoff, minus costs, minus reserves. What surprises investors is the first term. The lender sizes that loan on its own appraisal of the property today. Your after-repair value estimate (ARV, the projected value once work is finished) is a planning number, not a loan input.
Investors often assume a finished-value appraisal is built in. It is not. A lender cannot lend against a unit that has no walls, no permit and no tenant.
Here is the arithmetic, using modeled percentages rather than sourced market figures. Say a property appraises at X. On a standard rental, the maximum loan is 0.75 times X. Subtract what you owe today and the closing costs. What remains is the construction budget.
If you owe a lot, that remainder can be small or zero, however good the plan is. Think of the loan cap as a ceiling on today’s equity, not a bet on tomorrow’s value.
What Do Three Modeled Scenarios Look Like?
The table below expresses everything as a share of the lender’s as-is appraised value. These are hypothetical inputs, and closing costs are left as a separate line you subtract at the end. The 75% cap applies to standard rentals.
| Step | Strong equity | Thin equity | Fails |
|---|---|---|---|
| Appraised value (as-is) | 100% | 100% | 100% |
| Max loan at 75% LTV | 75% | 75% | 75% |
| Existing payoff | 40% | 65% | 78% |
| Left before costs | 35% | 10% | — |
| Reading | Funds a sizable addition | Small budget only | No cash-out |
The strong-equity case leaves room for a meaningful project after costs. The thin-equity case may cover a small scope, but costs eat into a 10% cushion fast. The failing case never reaches the starting line, because the existing loan already sits above the cap.
A fourth case fails for a different reason. Equity is fine, but the current rent cannot carry the larger loan at the required coverage. The lender cuts the loan until the rent can, and the cash drops with it.
Which Limit Binds First: Value or Rent?
Three checks run side by side, and the lowest result wins. They are the seasoning clock, the LTV ceiling and rent coverage.
The value check is the 75% cash-out LTV ceiling. The rent check compares monthly rent to PITIA, which is principal, interest, taxes, insurance and any association dues. The result is the DSCR, and the program minimum is 1.00. Stronger ratios open better pricing and leverage. Some select lenders in the network will consider coverage below 1.00, with leverage and terms adjusted, but treat that as an exception to plan around rather than the standard path.
Clearing 1.00 does not mean positive cash flow. DSCR counts rent against PITIA only. Repairs, vacancy, management, utilities and capex sit outside the calculation, so build a cushion into your own budget.
For an addition or ADU, the rent check has a catch. The lender needs a lease or a market-rent appraisal on the property as it exists today. Rent from an ADU that has not been built generally does not count. Your current rent has to carry the bigger loan before the new unit earns a dollar.
How Does the Ownership Clock Change the Number?
Most of the network expects about 6 months of ownership before it sizes cash-out on appraised value. The clock starts when the deed records. It does not start when the rehab ends or a tenant moves in.
Inside that window, cash-out is typically sized on the lower of appraised value or cost basis. Cost basis is your purchase price plus documented rehab spending. Incomplete receipts can reduce proceeds, so keep invoices and draw records from day one.
Delayed financing is a related path for true cash buyers. It sizes near your documented cost, still capped by the cash-out LTV. Extra appraisal equity stays put until seasoning ends. It does not let you borrow against ARV, and it rarely rescues a hard-money purchase, because that purchase carried a lien from the start.
What Does the Appraiser Actually Look At?
The lender orders its own appraisal. That value sizes the loan, and it should include a rent schedule. On a single-family home, the rent schedule is typically Form 1007. On a 2-4 unit property, the small-residential-income report is Form 1025. DSCR is not an agency product, so those form names are borrowed conventions. Fannie Mae’s ADU income explainer confirms that a Form 1007 accompanies an ADU appraisal.
Rent comes from the appraiser’s schedule, not from a number you pick, as Dwelling Index also notes. If an ADU already exists, make sure the report captures its rent and not only the main house.
Appraisers also weigh paperwork. A practitioner guide from Oregon’s environmental quality agency says appraisers look at proof of an ADU’s legality, rental agreements and build-cost breakdowns. It is an older document, so treat it as a description of method, not current program rules.
A legal ADU may support a higher appraised value, depending on comps and underwriter review. Skip any claim of a fixed percentage uplift. An unpermitted unit typically adds no value and no income.
How Do You Size the Project Backward From the Cash?
Work the formula in reverse before you hire a designer. Your project budget plus closing costs must fit inside 75% of as-is value, after your payoff. This table shows the maximum existing payoff for a given budget, before closing costs, on a standard rental.
| Budget (share of as-is value) | Max existing payoff before costs |
|---|---|
| 10% | 65% |
| 15% | 60% |
| 20% | 55% |
| 25% | 50% |
Subtract closing costs from the payoff column to get the true ceiling. If the existing loan carries a prepayment penalty, that also comes out of proceeds.
If your numbers land outside the table, the project may need other funding first. A recently refinanced or low-equity property can yield little or no cash, and no plan changes that.
What If the Property Is Not a Standard Rental?
Short-term rental. Cash-out on a short-term rental runs at 70% LTV, against 75% on a standard long-term rental. Expect a 640+ credit score and about 12 months of hosting history. 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. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Large balances. Cash-out on the network’s super jumbo programs exists only at or below $3,000,000. A borrower at a 680 score or lower gets no cash-out above $1,500,000. Reserves typically run about 6 months of PITIA and step up to about 9 months above $1,500,000. An ADU does not move any of these hard stops.
An existing ADU. A permitted, leased ADU can add rent to the coverage test. An unpermitted ADU is generally excluded from income. Short-term use of an ADU needs a documented operating history, counted at a discount.
Property types. DSCR financing through the network is not offered on manufactured homes (single- or double-wide), log homes, or barndominiums. That applies to the main house and any structure you plan to build.
Addition versus ADU. An addition adds square footage to the same unit, so the rent change may be modest and shows up only after an appraiser re-reads the property. An ADU creates a second rentable unit with its own rent, but only after construction, permits and occupancy approval are in place.
Which Path Funds the Build?
The honest answer is that a DSCR cash-out funds the build only when today’s equity covers it. Otherwise, the sequence matters.
| Path | Credits finished value? | Best fit |
|---|---|---|
| DSCR cash-out now | No, as-is value only | Plenty of equity, rent covers larger loan |
| Bridge or other funding first, DSCR refinance after | After completion | Thin equity, unit will be rentable |
| Purpose-built renovation product | Can credit finished value | Projects that need ARV-based sizing |
The build-then-refinance route works because the later appraisal sees a completed, rentable unit. The permit, the lease and the new rent all count at that point. A larger appraisal and extra rent can then support a bigger loan, subject to lender guidelines.
The two-step plan has a cost. You carry the first loan and its closing costs, then pay costs again on the second refinance. Run both sets of numbers before choosing it.
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.
Where Does This Plan Break?
Four failure points show up in the program rules.
- Low appraisal. If the value lands under your expectation, cash stays trapped in the deal. You can recoup what you paid in some structures, but you cannot borrow on ARV.
- Lump-sum proceeds. Cash-out arrives at closing, not in construction draws. Budget a contingency for overruns, because a second round of financing may be unavailable if the numbers shift.
- Reserves. Lenders ask you to hold reserves from your own funds. Cash-out proceeds never satisfy that requirement.
- Paperwork. Missing permits, rehab receipts or a rent schedule can shrink proceeds or exclude income.
Credit also shapes the outcome. A 620 floor exists in parts of the network, most programs want around 660, and 700 and above opens the strongest leverage tiers. For a project that needs every point of leverage, that difference matters.
An agency contrast helps here, briefly. Fannie Mae’s explainer says an existing ADU’s income is counted at 75% of lease or market rent and that a renovation-loan path applies when the ADU does not exist. Those are agency rules and do not govern DSCR loans. The useful lesson is shared: existing units earn credit, planned units do not.
Pre-Application Checklist
- Equity: estimate as-is value and your payoff, then run the 75% test (70% for a short-term rental).
- Ownership: confirm the deed recording date is about 6 months back, or gather cost-basis records.
- Rent: line up a current lease or market-rent appraisal for the property as it stands.
- Permits: collect approvals for any existing ADU, and plan the permit path for a new one.
- Reserves: plan about 6 months of PITIA from your own funds, and about 9 months above $1,500,000.
- Contingency: hold extra funds outside the loan for overruns.
Calculators are useful for these steps. Any calculator figure is an illustrative estimate, not a quote. For the broader mechanics, see Lendmire’s complete DSCR loans guide.
Key Terms Defined
DSCR: the ratio of a property’s monthly rent to its monthly PITIA.
LTV: loan-to-value, the loan amount as a percentage of the appraised value.
PITIA: principal, interest, taxes, insurance and any association dues, the full monthly housing obligation.
Seasoning: the ownership period a lender wants before it sizes a loan on appraised value.
ARV: after-repair value, your estimate of worth once work is complete.
Cost basis: purchase price plus documented rehab spending.
As-is value: what the property appraises for today, before planned work.
Frequently Asked Questions
Can a DSCR cash-out refinance fund an ADU that does not exist yet?
Yes, but only to the extent today’s equity allows. The loan sizes on the as-is appraisal, so the unbuilt ADU adds no value or rent to the file. Investors with thin equity often fund the build another way first and refinance once the unit is finished and leased.
Does the lender count my projected ADU rent?
Generally no. Rent from a unit that has not been built does not count toward coverage. The existing rent on the property has to carry the new loan at the required ratio, and the appraiser’s rent schedule, not your estimate, supplies the figure.
How long must I own the property first?
Most of the network expects about 6 months of ownership from the recorded deed. Inside that window, cash-out typically sizes on the lower of appraised value or cost basis. Cash buyers may use delayed financing, which returns roughly what you paid, capped by the cash-out LTV.
Do cash-out proceeds count toward reserves?
No. Reserves must come from your own funds, commonly around 6 months of PITIA, stepping up to about 9 months above $1,500,000. Proceeds from the loan itself never satisfy that requirement.
Will an ADU raise my appraised value?
It may, depending on comps and underwriter review, but only a finished, legal unit can. Unpermitted units typically add nothing. Treat any fixed percentage uplift with caution.
