The Quick Read: It depends on how much value the appraiser credits to the unpermitted space. Your cash is the new loan minus your old loan payoff minus closing costs, and the new loan is a percentage of appraised value. Unpermitted work does not change the formula. It changes the value that feeds the formula, and every dollar of lost loan capacity comes straight out of your check.
- Cash equals the capped loan, minus payoff, minus costs.
- Bank statement income decides whether you qualify. Appraised value decides how much you can borrow.
- Space the appraiser excludes is equity you cannot borrow against.
- A 10% drop in value can cut your cash by more than a third, depending on how much cash you were set to receive.
- No fixed national haircut exists. Treatment varies by appraiser, work type, and lender.
Self-employed owners often finish a basement, convert a garage, or add a room without a permit, then hit a wall at the cash-out stage. Strong deposits do not rescue a low appraisal. Income documentation and collateral value are separate tests.
Key Terms Defined
Cash-out refinance replaces your current mortgage with a larger one and pays you the difference in cash.
Appraised value is the appraiser’s opinion of what a typical buyer would pay for the property, not what you spent on it.
Gross living area (GLA) is the finished, permitted, above-grade square footage that appraisers use to compare homes.
Unpermitted work is construction or conversion done without the building permit the local jurisdiction required.
Payoff is the balance you owe on the existing loan, which must be cleared at closing before you receive anything.
Bank statement loan is an alt-doc mortgage that is reviewed around documented income taken from averaged deposits over 12 months of statements.
How the Cash Is Calculated
Start with appraised value. Multiply it by the maximum loan-to-value ratio (LTV, the loan as a percentage of value) for your occupancy. Subtract your payoff. Subtract closing costs. What remains is your check.
The ceilings depend on how you use the property. Across the wholesale network Lendmire works with, an owner-occupied primary residence cash-out generally reaches up to 80% LTV with a fixed expense ratio. That drops to 75% if you use an accountant-prepared expense ratio, so the accountant route is the lower ceiling. A second home generally tops out at 75% LTV, depending on loan size and credit. An investment property cash-out tops out around 75% LTV. Loan sizes typically run from roughly $125,000 to $3,500,000, and reserves commonly sit around six months of the housing payment. All of this is subject to lender guidelines.
Those ceilings are for cash-out. Higher figures you may see for primary-residence purchases or rate-and-term refinances do not apply here.
Here is why value matters so much. The payoff and closing costs do not shrink when value does. So the entire reduction in loan capacity lands on your cash.
Why a Small Value Drop Hurts So Much
Run the numbers on a modeled home at 75% LTV. Each $100 of appraised value the appraiser removes lowers your maximum loan by $75. If the excluded space equals 10% of the home’s value, your loan ceiling falls by 7.5% of the original value.
That 7.5% comes entirely out of your proceeds. If your cash was going to be, say, 20% of the home’s value, a 10% value cut takes more than a third of it. That is illustrative arithmetic, not a market statistic. If value lands below break-even, you bring cash to closing instead of receiving it.
Here is how three outcomes compare for the same house, using ratios instead of dollars:
| Appraisal outcome | Value credited | Max loan | Your cash |
|---|---|---|---|
| Space counted fully | 100% of value | Full cap | Highest |
| Space discounted | Reduced | Lower cap | Noticeably lower |
| Space excluded | Permitted space only | Lowest cap | Smallest, or zero |
Payoff and closing costs stay identical in every row. Only the value credited, the max loan and your cash change.
What Appraisers Actually Do With Unpermitted Space
Appraisers disclose it, and they usually keep working. The agency standard is a useful contrast, even though bank statement loans are non-QM products and not agency loans. The Fannie Mae Selling Guide tells an appraiser who finds an addition without the required permit to comment on the work’s quality and appearance and on its impact, if any, on market value.
Notice the words “if any.” A practitioner analysis from Local Real Estate Online points out that the guide neither assigns zero value nor tells the lender to decline. The rule does not dictate the outcome. The individual lender’s overlay and the appraiser’s judgment do.
In practice, appraisers often decline to count unpermitted additions in square footage. HomeLight gives a bedroom-count example: an extra room in a four-bedroom home may be treated as if the home were a three-bedroom, with no value given to the extra room. Appraisers typically spot the work by comparing what they see against public records, such as a finished room missing from the tax-record square footage.
The report can land three ways. The space is counted because comparable sales support it. The space is excluded or discounted. Or the value is made subject to a condition, such as legalizing or removing the work. That third outcome is the hardest one to build a loan around.
Does Bank Statement Qualification Relax the Property Review?
No. A bank statement loan is reviewed on documented income under the applicable program, subject to lender guidelines. It looks at 12 months of business or personal statements, uses deposit averages, and applies lender-specific expense factors. Expense factors differ by lender, so never assume a universal formula.
None of that touches collateral. The property still gets a full appraisal, and cash-out files should not count on an appraisal waiver. A lender can approve your income and still size the loan down because the appraiser would not credit your finished lower level.
Lender overlays on unpermitted items vary across the network. Some programs are relaxed when the work is cosmetic. Others want the work legalized or removed. Programs that follow conventional agency-style guidelines tend to be stricter than non-QM, according to a seller-side explainer from Effective Agents, which notes those deals may need resolution before closing. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, but the condition of the property and any unpermitted work can still affect how a lender treats the file.
Not All Unpermitted Work Is Treated Alike
Size and safety drive the outcome. Here is how the main categories generally compare:
| Type of work | Likely treatment | Risk level |
|---|---|---|
| Cosmetic or minor repairs | Often little effect | Low |
| Finished basement | May be discounted or excluded | Moderate to high |
| Room addition | Often excluded from GLA | High |
| Garage conversion | Often excluded | High |
| Unpermitted ADU | Frequently excluded | High |
| Electrical or structural changes | Safety concerns raise the stakes | High |
Four factors decide where your file lands: the size of the work relative to total value, whether comparable sales support the space, the quality of the work, and whether it touches safety systems. Then the lender’s overlay applies on top.
Occupancy Changes the Paperwork
Occupancy decides which regime governs your file. A bank statement loan on your primary residence or second home is a consumer mortgage, and it follows consumer disclosure rules. A bank statement loan on a non-owner-occupied rental, including a short-term rental, is generally treated as business-purpose and exempt from those consumer disclosure requirements, though your loan officer confirms how your specific file is classified. Short-term rental rules vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income.
Leverage also differs. A rental cash-out tops out around 75% LTV, the same as a second home, while a primary residence can reach 80% with the fixed expense ratio. If you hold the property as a rental and the question becomes coverage rather than documented income, a rent-based option may fit better. The complete DSCR loans guide explains how that route works. Unpermitted rent, such as from an extra unit, is generally left out of coverage on that side.
Your Options When Value Comes In Low
You have five realistic paths, and the right one depends on how big the gap is.
1. Proceed as-is. Let the report disclose the work and take the smaller check. This works when the cash still covers your goal.
2. Permit first. Pursue a retroactive or as-built permit before the appraisal. It can take effort, but it may let the space count.
3. Remove or reverse the work. This is rare, but it fits when the conversion is small and the permitted layout is the valuation basis.
4. Do a rate-and-term refinance now. Delay the cash-out until the permit issue is resolved.
5. Walk away from the cash-out. If the value hit erases the benefit, skip it.
One trap deserves a warning. Do not plan on using the proceeds to fix the permit problem. If the unpermitted space shrinks your check, the money you counted on may not exist.
Investors running a rehab-then-refinance strategy feel this hardest. Doing the rehab without permits weakens the step where you refinance and recover your capital. Appraisers estimate what a buyer would pay, not what the work cost, so the spend may never show up in value. An improvement may support a higher appraised value, depending on comps and underwriter review. It does not add a guaranteed amount.
Exit risk follows the house, too. An appraiser practitioner blog notes that valuation uncertainty and disclosure issues come up again at resale or the next refinance.
Before the Appraiser Visits
Preparation protects your number. Work through this list:
- Pull your permit history and compare it to the work in the house.
- Tell your broker about the work up front, so the file is matched to a lender whose overlay fits.
- Gather 12 months of statements and confirm the deposit story is clean.
- Ask which comparable sales support the space, if any.
- Keep documentation of the quality of the work, such as receipts and contractor details.
Disclosing early beats surprises. Appraisers note unpermitted space and typically proceed. A mismatch you hid still shows up, and it can slow the file or reshape the loan.
Frequently Asked Questions
Will unpermitted work get my bank statement cash-out denied?
Not automatically. The agency appraisal guidance asks the appraiser to comment and assess any value impact, and non-QM lender overlays vary. The work can reduce the loan, trigger a condition, or in some cases cause a decline if it touches safety systems or the lender’s overlay forbids it. Every file is underwritten individually.
Does the appraiser value unpermitted space at zero?
Sometimes, but not always. Appraisers often exclude unpermitted square footage from living area, and some discount it instead. Outcomes depend on comparable sales, the quality of the work, and the lender’s instructions. Treat zero as a possibility, not a rule.
Does strong bank statement income make up for a low appraisal?
No. Income qualification and collateral value are separate tests. Deposits determine whether you qualify, while appraised value caps how much you can borrow. A strong income file cannot raise the value of space the appraiser will not credit.
What LTV applies to a bank statement cash-out?
On an owner-occupied primary residence, generally up to 80% LTV with a fixed expense ratio, or 75% with an accountant-prepared ratio. A second home generally reaches 75%, and an investment property cash-out tops out around 75%. These are typical ranges through select lenders, subject to lender guidelines.
Can I use cash-out proceeds to legalize the work?
You can plan for it, but do not count on it. If the appraisal excludes the space, your check shrinks, and the funds you earmarked may fall short. Resolving permits first is the safer sequence.
What to Ask a Lender Before You Apply
Ask four things. How do you treat unpermitted square footage in your appraisal instructions? Will you size the loan on the full value or only the permitted space? Does your overlay differ for finished basements, additions, or ADUs? And what happens if the report is made subject to a condition?
