The Quick Read: Unpermitted work does not automatically block a DSCR cash-out refinance, but it changes how the property is valued, and value drives the loan amount. The appraiser decides how to treat the work, and the lender decides what conditions to attach. Expect a smaller loan, a permit condition, or in some cases a decline.
- Cash-out refinances top out around 75% LTV on standard rentals, with about 6 months of ownership expected.
- Qualifying coverage starts at 1.00 on select programs, and the loan is sized on the lower of the value test and the rent test.
- A full appraisal is the norm on cash-out, so the work will be seen.
- Livability work (electrical, structural, an added bedroom or unit) is treated harder than cosmetic work.
- Permit and document the work before the exit refinance, not after. Terms depend on the lender’s guidelines, the property type, the leverage, and a full review of the credit profile.
Here is the plain version. Unpermitted work is a valuation problem first and a loan problem second. The rest of this piece walks through how underwriting handles it, step by step.

What Counts as Unpermitted Work?
Unpermitted work is any construction that needed a building permit and never got one, or got one that was never closed out. Common examples: a finished basement, a garage turned into living space, a bedroom added without sign-off, a new bathroom, rewired electrical, or a full accessory unit.
Cosmetic work is different. Paint, flooring, and fixtures usually need no permit and rarely cause trouble. The line that matters to a lender is whether the work changes the size, systems, or legal use of the home.
How Does Underwriting Treat It, Step by Step?
Think of the file moving through five gates. Unpermitted work can snag any of them.
Gate 1: The appraisal. Cash-out refinances almost always get a full appraisal. Waivers are rare at this leverage. The appraiser walks the property, measures it, and reports what they see.
Gate 2: Value. When an appraiser spots an addition without the required permit, the standard appraisal guidance has them comment on the quality of the work and any effect on market value. That means the treatment is case by case. This is general appraisal practice, as described in the Fannie Mae Selling Guide section on the improvements section of the appraisal report, and it does not set DSCR program rules. Some appraisers count the space, some discount it, some leave it out of the square footage entirely.
Gate 3: Loan sizing. Your loan is the lower of two numbers. The first is appraised value times the cash-out LTV cap, which is 75% on standard rentals. The second is the loan the rent supports at the required coverage. If the appraiser strips out value, the first number drops. Every dollar of value lost removes roughly 75 cents of loan.
Gate 4: Rent. Rent has to be supported by the appraisal’s rent schedule. On a single-family rental, the appraiser documents market rent on Form 1007, which Freddie Mac publishes as the single-family comparable rent form. For two- to four-unit properties, the appraisal uses Form 1025. Here is where unpermitted space bites. Rent from a room or unit that is not legal may not be counted. A fourplex that is really a triplex plus an illegal fourth unit gets underwritten as a triplex.
Gate 5: Title and conditions. Open permits or code violations can surface in title work or local records. Some lenders will condition closing on closing out the permit or getting a retroactive sign-off. Others will not touch it.
Why Seasoning and Paperwork Matter
Inside the first months of ownership, many lenders size the loan on cost rather than appraised value: purchase price plus documented rehab. That is the basis a BRRRR-style investor leans on. It falls apart with unpermitted work. Spend without invoices or permits generally cannot be counted in cost basis.
After about 6 months of ownership, measured from title recording, the appraised value takes over as the basis. The unpermitted work then lives or dies on what the appraiser reports.
The lesson for rehab-driven investors: your after-repair estimate is not the number. The new appraisal is. Lenders on our network do not size DSCR loans on a projected after-repair value.
What Does the Work Type Change?
Not all unpermitted work gets the same reaction. Here is how it typically sorts.
| Work type | Likely treatment | Typical fix path |
|---|---|---|
| Cosmetic updates | Usually ignored | None needed |
| Finished basement or garage conversion | Space may be excluded from value | Retroactive permit or exclude it |
| Added bedroom or bathroom | Value discounted; rent may be questioned | Permit and inspection |
| Electrical, plumbing, structural | Harshest treatment; may be a condition | Licensed repair and sign-off |
| Added unit or ADU | Unit count and rent schedule may change | Legalize first |
Livability and safety items get the toughest handling. A lender worries less about a painted deck than about rewired panels no inspector ever saw.
The Worked Example (Percentages and Ratios Only)
Say you own a duplex you bought and rehabbed. You added a finished basement bedroom without a permit. You expect a 75% cash-out on a value that includes it. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
- The appraiser excludes the basement space. Appraised value comes in lower than your plan.
- The 75% LTV cap now applies to a smaller number, so the value-side loan shrinks.
- Your payoff plus exit costs stay the same. Cash back shrinks, and a large enough miss turns a cash-out into a cash-to-close file.
- On the rent side, if the basement bedroom had been part of your rent assumption, rent used for lender review drops too. Coverage can slide from a comfortable low-1.2x toward 1.00 territory. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Two mechanics matter here. First, the break-even appraisal is payoff plus exit costs, divided by the LTV cap. Compute it before you order the appraisal. If a realistic value excluding the work still clears break-even, you have a deal. If not, you do not.
Second, a bigger loan lowers coverage because the payment rises. So a smaller cash-out can help the ratio even as it hurts your proceeds.
Where the General Rule Breaks
A few edge cases change the answer.
The lender offers a no-cash-out refinance instead. If value lands too low for cash back, some lenders will do a rate-and-term refinance at up to 85% LTV with no cash at closing, or decline. That can still be useful if you are paying off a short-term loan. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
The work is the whole point of the property. If the unit count itself is unpermitted, such as a converted garage rented as a unit, you may be financing a different asset than you think. The underwritten rent schedule follows the legal count.
The appraiser reports “subject to.” Most programs want the property rent-ready at appraisal. If value is reported subject to repairs or completion, the lender typically requires a re-inspection after the work is done.
Coverage is thin. Coverage below 1.00 is available through select lenders in the network, with leverage and terms adjusted. Pulling rent out of an unpermitted space can push you into that territory. It is a different path from the 1.00-and-up programs, not a softer version of them.
Property type. Manufactured homes, log homes, and barndominiums are not offered in the network’s DSCR programs, permits or not.
What Should the Investor Do?
Work backward from the exit.
1. Permit before you refinance. Closing out permits before the appraisal is the cleanest fix. Retroactive permits vary widely by jurisdiction, so start early.
2. Keep every invoice. Documented spend supports cost basis inside the seasoning window and shows the work was real.
3. Run break-even first. Know the lowest value that still works, with and without the unpermitted space.
4. Underwrite rent from legal space only. Build your coverage on units and rooms that would survive a records check.
5. Disclose. Hiding the work is a bad plan. The appraiser measures, and records exist.
6. Plan reserves. Reserves commonly run about 6 months of PITIA, stepping up to about 9 months on loans above $1,500,000, varying by lender and file.
A larger equity cushion helps, but it never erases leverage caps, credit floors, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage. Credit tiers typically run from a 620 floor up through 660, 680, and 700. Clearing 1.00 coverage also is not the same as positive cash flow, because repairs, vacancy, and management sit outside the calculation.

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.
Key Terms Defined
DSCR (debt service coverage ratio): Monthly rent used for lender review divided by the full monthly payment on the loan.
PITIA: Principal, interest, taxes, insurance, and association dues, the full monthly housing obligation.
LTV (loan-to-value): The loan balance as a percentage of the appraised value.
Seasoning: The ownership period a lender wants before it will size a loan on appraised value.
Break-even appraisal: The lowest value at which payoff plus exit costs still fit under the LTV cap.
Unpermitted work: Construction that required a permit and never received one or never had it finalized.
Frequently Asked Questions
Will a DSCR lender refuse to refinance because of unpermitted work?
Not automatically. Outcomes depend on the lender, the appraiser, and the type of work. Cosmetic items rarely matter. Livability work may bring a permit condition, a value discount, or a decline. Qualification is subject to lender guidelines and property review.
Does unpermitted square footage count in the appraisal?
Sometimes. Appraisers are expected to comment on the work and its effect on market value, so treatment is case by case. Many exclude or discount space with no permit. Plan your numbers on value without it.
Can I count rent from an unpermitted unit?
Usually not. Rent used for lender review follows the appraisal’s rent schedule and the legal unit count. A unit that is not legal often drops out of the calculation, which can pull coverage down.
What if the appraisal comes in low because of the work?
The loan shrinks by about 75 cents for each dollar of lost value on a standard rental cash-out. You can take a smaller cash-out, switch to a no-cash-out refinance, close out permits and reappraise, or wait.
Should I permit the work before or after refinancing?
Before, in most cases. Permitting first removes the biggest unknown from the appraisal and title review. Waiting risks a low value, a condition, or a decline.
