The Quick Read: Usually less than the same property would return with clean records, because the appraisal sets the loan ceiling and unpermitted space often gets excluded from value or discounted. Cash to you is the maximum loan, minus the payoff on the existing loan, minus closing costs, and every dollar cut from value comes straight out of that last number at a fixed leverage cap. The file is rarely dead on arrival, but the check can shrink a lot, and sometimes to zero.
- Cash-out on a standard rental tops out around 75% LTV across most of the network, subject to lender guidelines.
- Unpermitted space may be left out of value, discounted, or valued by comparable sales, depending on the appraiser and underwriter.
- Rent from an unpermitted unit may be left out of the coverage calculation.
- The payoff does not shrink when value does, so the borrower absorbs the full loss.
- Permitting, restoring, or taking a smaller draw are the main paths to protect cash.
The Cash Formula, Step by Step
The formula is simple: appraised value times the LTV cap gives the maximum loan. Subtract the existing payoff and closing costs. What is left is your cash.

Program availability and eligibility are subject to lender guidelines, credit approval, property review, and underwriting.
Across most programs in Lendmire’s wholesale network, cash-out on a standard rental tops out around 75% LTV, with about 6 months of seasoning measured from title recording. Coverage of 1.00 is where select programs start, and credit floors run from 620 up, with most programs wanting around 660. Reserves commonly run about 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000. These are typical ranges, and every file is underwritten individually.
Here is why the appraisal matters so much. The LTV cap is fixed, and so is the payoff. Value is the only variable, so any change in value moves the check by the full amount times the cap. The table below shows how a modest drop in value can cut cash by a larger share than the value lost.
What Does a Value Haircut Do to the Check?
An excluded or discounted space cuts the maximum loan at the same percentage as the value drop. The table uses modeled percentages only, not market data. Assume a property where the borrower expects value to support a maximum loan equal to 100 units, with the existing payoff at 70 units and closing costs at 3 units.
| Scenario | Value vs. expected | Max loan | Net cash (units) |
|---|---|---|---|
| Clean records | 100% | 100 | 27 |
| Space discounted | 90% | 90 | 17 |
| Space excluded | 80% | 80 | 7 |
| Larger exclusion | 73% | 73 | 0 |
In the table, a 10% drop in value takes cash from 27 to 17 units, a loss of about 37% of the expected cash. A 20% drop takes it to 7 units, a loss of nearly three-quarters. At a 27% drop, where value sits at 73% of expected, the check disappears, and past that point the borrower would have to bring money to closing or switch to a different structure. That break-even moves with your payoff: the higher your existing loan balance relative to value, the sooner it arrives.
Will the Appraiser Exclude the Space?
Maybe. There is no universal rule. Appraisers often can’t include unpermitted square footage in their valuation, as Redfin notes in its guidance on selling with unpermitted work. Outcomes tend to fall into a few buckets: the space is described separately, left out of gross living area, valued below permitted space, or given little or no value.
Two things drive this. First, comparable sales. If nearby homes sell with similar finished space and the market pays for it, an appraiser may support some value. If not, the number can land near zero. Second, measurement. Basements, attics and low-ceiling areas can fall outside gross living area under the ANSI measuring standard even when permitted, so exclusion can come from the measuring rules, the permit status, or both.
For contrast only: agency guidance, which does not govern DSCR loans, asks the appraiser to comment on an unpermitted addition’s quality and any effect on market value rather than imposing a flat deduction. Fannie Mae’s Selling Guide says the appraiser comments on “if any” value impact. The lesson carries over: appraisers judge case by case, and absolutes in either direction are wrong.
How Does the Appraiser Find It?
Appraisals are not permit audits, but the work often shows. The appraiser measures the home and compares the result with public records and the tax roll. A square-footage mismatch is a common trigger. Layout oddities, construction-quality problems, and safety issues can also flag it. Some work that looks unpermitted is actually permitted but never updated in assessor records, so a records check before you apply is worth the effort.
DSCR cash-outs on investment property typically call for a full appraisal with a rent schedule: Form 1007 for single-family rentals and Form 1025 for 2-4 units. Those forms are named in agency paperwork, though DSCR loans are not agency products.
The Income Side: When the Loan Shrinks Twice
The appraisal is only half the test. DSCR compares rent used for lender review to PITIA, and if the unpermitted space is a rentable unit, such as an ADU or converted garage, some lenders will not count its rent. The coverage ratio can then fall at the same time the value falls.
A lower loan means a smaller payment, which partly offsets the lower rent, but the offset is rarely complete. Clearing the coverage floor also isn’t the same as positive cash flow. DSCR leaves out repairs, vacancy, management, utilities and capex.
If coverage lands below 1.00, a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. That path generally means less cash, not more.
Step-by-Step: Check Before You Apply
1. Pull county records. Compare recorded square footage and bedroom count with what the property actually has.
2. Sort the work. Separate cosmetic updates in existing space from additions, new rooms, and electrical or plumbing changes.
3. Measure by the standard. Ask whether the space would count in gross living area even if permitted, given ceiling height and access.
4. Look for comps. Find recent sales nearby that include similar space, because they decide whether an appraiser can support any value.
5. Run the math both ways. Build the cash formula at full value and at a reduced value, and see where the check hits zero.
6. Talk to the broker before ordering. Lender overlays on unpermitted work differ, and the underwriter’s policy, not the appraiser’s report, is the last word. Lendmire can compare options across lenders in its network.
Paths When the Number Comes in Low
| Path | Effect on cash | Trade-off |
|---|---|---|
| Refinance as-is | Smaller check on reduced value | No added cost; fastest to define |
| Permit first | May restore value if the space counts | Out-of-pocket permit and inspection costs |
| Restore or remove the work | Value reflects permitted footprint | Loses the space and its rent |
| Smaller draw | Matches loan to lower value | Less capital for the next deal |
| Payoff-only refinance | No cash back | Keeps the loan structure moving |
| Delay the cash-out | Preserves option to fix first | Capital stays tied up |
A reconsideration request is a legitimate step after a low appraisal. Bring recent in-neighborhood sales that include similar space, contractor invoices, photos, any retroactive permit or final inspection, and proof the work is finished and safe, with no exposed wiring or open plumbing.
Retroactive permits cost money and the timeline varies by jurisdiction. Weigh those costs against the extra cash they might unlock. If the unlocked cash is small, as-is can beat a permit chase.
Which Work Is Low Risk and Which Isn’t?
| Type of work | Typical appraisal risk |
|---|---|
| Paint, flooring in existing space | Lower; generally reflected in value |
| Finished basement or attic | Moderate; measuring rules may exclude it |
| Added room or addition | Higher; may be left out of value |
| Converted garage or ADU | Higher; value and rent may both be left out |
| Electrical or plumbing changes | Higher; safety and insurability questions |
Treat this as a rough guide, not a ruling. Lenders also look at insurability. Shovels points out that unpermitted additions may not be covered by homeowner’s insurance, and title insurance generally doesn’t cover unpermitted work.
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.
What This Means for a BRRRR Plan
Equity on paper and cash you can pull can differ. Money spent on unpermitted work may not lift the appraisal. A rehab-and-refinance plan that counts that work toward value can come up short, so model the refinance with the unpermitted portion at zero first. If it still works, anything the appraiser credits is upside.
Plan the exit too. A future buyer’s lender appraisal may treat the space the same way. The complete DSCR loans guide covers how the program works end to end.
Key Terms Defined
Cash-out refinance: A new loan larger than the payoff of the old one, with the difference paid to the borrower.
LTV: Loan-to-value, the loan amount divided by appraised value.
Gross living area: The finished, above-grade square footage an appraiser counts toward value.
Excluded versus discounted space: Excluded space gets no value in the report; discounted space gets less value than permitted space.
DSCR: Rent used for lender review divided by PITIA, which measures whether the property’s income covers its payment.
Frequently Asked Questions
Can I get a DSCR cash-out refinance at all with unpermitted work?
Often yes, though not on every file. Many lenders let the loan proceed with the unpermitted space left out of value. Others require the work to be permitted or removed, and some decline. Treatment varies by lender, so a broker comparing several programs helps.
Does rent from unpermitted space count toward coverage?
Not always. Some lenders will not count rent from an unpermitted unit in the DSCR calculation. If the property depends on that rent to clear the floor, the coverage ratio can drop while the value drops too.
Is the appraiser required to give the space zero value?
No. There is no universal rule. Comparable sales with similar space can support some value, and the appraiser judges each case. Anyone claiming a flat zero or a flat percentage is overstating it.
What happens if the appraisal comes in low?
You can ask for appraisal reconsideration with comps and documents, take a smaller draw, switch to a payoff-only refinance, permit or restore the space first, or wait. Which one works depends on how far the check sits above the break-even.
Does a larger down payment or more equity fix this?
Equity helps, but it does not erase the 75% LTV cap on a standard rental, credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
