The Quick Read: It depends on the type of work, how the appraiser reports it, and which lender reviews the file. No rule bans a cash-out refinance on a property with unpermitted work, but the appraisal decides whether that work counts toward value and rent.
- Value sets the ceiling: cash-out on a standard rental tops out around 75% LTV, so any value the appraiser removes shrinks the proceeds.
- Rent matters too: space that isn’t legal may not count toward rent used for lender review, which can pull the coverage ratio down.
- Cosmetic work in existing space rarely moves the needle; added rooms, structural changes and unit-count changes do.
- Typical guidance for a cash-out is about 6 months of seasoning, a 1.00 coverage floor on select programs, and a 620 credit floor, all subject to lender guidelines.
- Large retail lenders and wholesale DSCR lenders each set their own property rules, so the right fit depends on your situation.
An investor holding a duplex with a converted garage or a finished basement usually asks the same thing: will anyone lend against this? Often yes. The harder question is how much, and the answer sits in the appraisal. This guide walks through the mechanics, the structures that exist, and where the general rule breaks. The complete DSCR loans guide covers the basics of the product itself.

Key Terms Defined
DSCR (debt service coverage ratio): Monthly rent used for lender review divided by the full monthly obligation of principal, interest, taxes, insurance and any HOA dues.
Cash-out refinance: A new loan that pays off the old one and returns the leftover equity to the borrower.
Unpermitted work: Construction, conversion or system changes done without the building permits or final inspections the local jurisdiction requires.
Gross living area (GLA): The finished, legal, above-grade space an appraiser counts when comparing a home with similar sales.
Rent schedule: The appraiser’s market-rent opinion, on the 1007 form for single-family and the 1025 form for two to four units.
Open code violation: A recorded enforcement action on the property, which is a different problem from missing permits with nothing on record.
Do Banks Actually Offer This?
Large retail lenders and depository institutions are bound by federal appraisal standards, and their own policies are often stricter than the baseline. DSCR loans, though, are not agency products.
Regulated banks and credit unions follow the Interagency Appraisal and Evaluation Guidelines, which require the appraiser to analyze and report the property’s actual physical condition, use and zoning. The FDIC’s appraisal FAQ notice collects how the agencies interpret those rules. Those guidelines bind regulated institutions. They are not a DSCR-specific rule, and they don’t say how to treat unpermitted space.
Lendmire is a mortgage broker, not a lender. It works with a wholesale network of DSCR lenders and matches a scenario to the program that fits. For unpermitted work, that matching matters, because lenders differ on what they’ll count. The best program for your situation depends on the work, the appraisal, the leverage you need and your credit profile.
How Underwriting Treats Unpermitted Work, Step by Step
Step 1: The appraisal is ordered. A cash-out refinance generally gets a full appraisal with a rent schedule.
Step 2: The appraiser measures and compares. The appraiser checks the property against county or tax records. A square-footage mismatch, an odd layout or visible quality problems can reveal unpermitted work. Appraisals are not permit audits, as one contractor-side explainer notes. The appraiser spots mismatches rather than searching permit files.
Step 3: The appraiser reports it. Common outcomes include excluding the space from GLA or discounting it. Another is stating value with an assumption that the work is acceptable. Practitioner write-ups describe exclusion or discounting of the space and assumption-based reporting. Where comparable sales have similar unpermitted space, a lender may give it more credit.
Step 4: Underwriting decides. The lender chooses whether to count the work, discount it or add conditions.
Step 5: Value sets the loan ceiling. A lower value means a smaller maximum loan at the same LTV. Because the payoff is fixed, the shortfall comes out of the cash-out proceeds. A modest value miss can erase much of the cash-out.
Step 6: Rent and coverage are retested. If the unpermitted space is rented, the lender decides whether that rent counts. A unit that isn’t legal may not count toward rent used for program review. Run the coverage ratio both ways before you apply.
Step 7: Title is reviewed. Lender’s title insurance covers defects like liens, not building-code violations. A California title policy form explicitly excludes code violations, including unpermitted construction. Unpaid contractors and mechanic’s liens are a separate title issue.
What Agency Rules Say (A Contrast, Not a Rule)
Fannie Mae’s Selling Guide has an “Additions without Permits” subsection in B4-1.3-05. As quoted by secondary sources, it asks the appraiser to comment on the work’s quality and appearance and on its impact, “if any,” on market value. One practitioner reading says that wording doesn’t tell the appraiser to assign zero value, and doesn’t tell the lender to decline.
Fannie Mae’s appraisal FAQ, as secondary sources describe it, says a non-compliant accessory unit has to be shown as typical for the market through at least two comparable sales with the same non-compliant use. Appraisers debate how to apply this in practice.
None of this governs a DSCR file. A DSCR lender can be stricter or looser, which is why the same property can read differently from one program to the next.
Which Type of Work Changes the Outcome?
The type of work drives the lender’s concern more than the mere absence of a permit.
| Type of work | Typical lender concern | Usual path |
|---|---|---|
| Paint, flooring in existing space | Minimal | Usually reflected in value |
| Added room or finished basement | Value and GLA | Space excluded or discounted |
| Structural, electrical, plumbing | Safety and uncertainty | Conditions or inspection |
| Garage or ADU conversion | Legality and rent | May not count for rent |
| Unit-count change | Legal unit count | Retest value and coverage |
Cosmetic changes in existing space are usually reflected in value. Added rooms and structural, electrical or plumbing work create more uncertainty. Safety problems and unit-count changes raise the odds of a decline, while sound work supported by comparable sales is easier to underwrite.
One distinction is worth drawing. Unpermitted work with nothing on record is different from an open code violation. Open violations are a much bigger problem for any lender. Missing permits from a prior owner are a quieter issue, though that is a general pattern rather than a rule, and it varies by market.
How It Plays Out: A Labeled Illustration
Consider a modeled scenario, not a market fact. An investor owns a duplex worth, say, $400,000 on the appraiser’s opinion if everything counts. A cash-out refinance on a standard rental tops out around 75% LTV. If the appraiser excludes an unpermitted finished basement and the opinion of value drops meaningfully, the 75% ceiling applies to the lower number. The existing payoff doesn’t change, so the cash-out shrinks by the full amount of the loan-size reduction. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Rent works the same way. If the basement unit is rented and the lender won’t count it, the rent used for eligibility review falls while the monthly obligation stays the same. A file that clears around 1.3x with the unit might land closer to 1.0x without it. That is borderline on programs that start at 1.00. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted, but that is a different program, and it comes with tradeoffs.
Also keep in mind that clearing 1.00 is not the same as positive cash flow. DSCR compares rent to the full monthly obligation only. Repairs, vacancy, management, utilities and capex sit outside the calculation.
Parameters to Expect
Across the wholesale network, the typical shape of a cash-out refinance looks like this, subject to lender guidelines and individual underwriting:
- Cash-out LTV on a standard rental tops out around 75%.
- About 6 months of seasoning, measured from title recording, is the common expectation.
- A 1.00 coverage floor is where select programs start; stronger ratios open better pricing and leverage.
- Credit tiers run from a 620 floor through 660 and 680 up to 700, and the strongest tiers sit at the top of that range.
- Reserves commonly run around 6 months of PITIA, and loans above $1,500,000 typically step up to about 9 months.
- Loan sizes go up to $3,000,000 on standard programs.
Manufactured homes, log homes and barndominiums are not offered through these programs, regardless of permit status. Short-term rental collateral is a separate lane, with cash-out around 70%, and the short-term rental cash-out refinance guide covers it. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
A recent purchase or rehab raises its own question. If the cash-out is sized off cost basis, a rehab with no invoices and no permits is hard to document. Confirm how a specific program treats that before you rely on 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.
Refinance As-Is, Permit First, or Restructure?
The decision comes down to three paths, and the right one depends on how much the unpermitted work moves value and rent.
Refinance as-is. If the work is cosmetic or the appraiser gives it little weight, accept the value and move forward. This works best when the cash-out you need still fits inside the reduced ceiling.
Retroactively permit the work. If the work is substantial and sound, legalizing it can restore value and rent credit. Permit-time inspections can reveal fixes, so the cost is uncertain. Permits pulled during a rehab are generally cheaper than retrofitting later.
Restructure the request. Take a smaller cash-out, delay the cash-out, or remove or reverse the work. If the space isn’t in the rent roll or the unit count, the file can be simpler.
Two further notes for BRRRR investors. Appraisers value the property as it stands, not on the after-repair estimate, and your rehab budget is not the value. And unpermitted work can leave an insurer unwilling to pay a claim, and it creates problems at sale. Those costs sit outside the loan but belong in the decision.
What to Assemble Before You Apply
- A candid list of every change made to the property, and who did it.
- Permit history from the local jurisdiction, including any closed or open permits.
- Contractor invoices and, for structural work, an engineer’s or inspector’s report.
- A current rent roll that separates legal units and any unpermitted space.
- Your coverage ratio calculated with and without the questionable space.
Questions to Ask Before You Commit
- Does this program count rent from space that isn’t permitted?
- Will the appraiser’s value be used as-is, or can it be reviewed against comparable sales?
- Does the program require permit verification or an inspection for this type of work?
- How is a cash-out on a recent purchase or rehab sized?
- What happens if the appraisal is made “subject to” completion or repair?
A broker that shops multiple wholesale lenders can put those questions to several programs at once. That is the practical advantage over approaching a single institution.
Common Mistakes
- Assuming title insurance covers it. It generally doesn’t cover code violations.
- Assuming the appraiser will always find it, or always zero it out. Neither is reliable, and the Fannie Mae wording itself requires a comment, not a mandatory exclusion.
- Assuming automatic denial. Outcomes vary by lender and by the type of work, and a file may see a reduced value, added conditions or a decline depending on the program.
- Treating the rehab budget as the value. The appraisal sets value.
- Assuming every lender must treat it the same way. Each lender sets its own rules on unpermitted space.
- Overlooking the contrast with FHA and VA loans. Government loans tie to minimum property standards, and unpermitted structural work can trigger repair conditions. A DSCR lender isn’t bound by those standards, so a property that fails one lane may still fit another.
Frequently Asked Questions
Can I get a DSCR cash-out refinance if my property has unpermitted additions?
Often yes, but the outcome depends on the work and the lender. The appraiser reports the space, and the lender decides whether to count it, discount it or add conditions. Cosmetic changes rarely matter, while added rooms and structural work create more uncertainty. Eligibility is subject to lender guidelines, credit approval and property review.
Will rent from an unpermitted unit count toward my coverage ratio?
That is a lender-specific call. Calculate the ratio with and without the unit so you know how the file looks in the worst case.
Does unpermitted work mean the appraiser will assign zero value?
Not necessarily. The agency wording asks the appraiser to comment on quality and market-value impact “if any,” and appraisers disagree on how to apply it. Some exclude the space from GLA, some discount it, and some credit it when comparable sales have similar space.
How does lost value affect my cash-out?
Directly. The 75% LTV ceiling applies to the appraised value, and your payoff stays fixed. Every dollar of value the appraiser removes reduces the loan ceiling, and the difference comes out of your proceeds. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
Which lender type is the best fit?
That depends on your situation. Regulated banks follow federal appraisal guidelines and add their own policies. Wholesale DSCR lenders each set separate property-eligibility rules. A broker can compare programs against the specific work, the rent and your leverage needs.

Permits pulled while the work is happening cost far less than permits chased after an appraiser flags a mismatch, and that is a more affordable way to protect a future cash-out.
