The Quick Read: No ranked list of providers exists, because the right fit depends on how the appraiser reports the unpermitted work, whether the lender counts the income from that space, and whether short-term rental use is legal at the address. Lendmire is a mortgage broker, so it matches your scenario to the wholesale lenders whose guidelines suit it. It does not rank companies.
- Unpermitted work does not automatically block a cash-out refinance. It can lower the appraised value, which lowers the maximum loan.
- Income from an unpermitted unit, such as a rented garage conversion, is generally left out of qualifying.
- A building permit and a short-term rental license are two separate checks. Either can reduce counted income.
- On short-term rental collateral, cash-out leverage tops out at 70% LTV, with a 1.00 coverage floor on refinances on select programs.
- Permit status is far cheaper to check before you apply than after an appraisal comes back low.
Why a Ranked List Would Mislead You
A “top providers” list sounds helpful, but it would be wrong for most readers. Each lender in a DSCR network sets its own rules for collateral, short-term rental history, and unpermitted work. The lender that fits a fully permitted cabin does not necessarily fit a house with a converted garage.

Lendmire works with a network of wholesale lenders and shops your file across them. That is the broker advantage: you see how many sets of guidelines treat your exact situation, rather than one company’s menu. The best program for your situation depends on the property, the credit profile, the leverage you need, and what you can document.
A DSCR loan, short for debt service coverage ratio loan, qualifies primarily on property-level rental income covering the payment, subject to lender guidelines. Because it is a business-purpose investor loan, it is reviewed differently from a standard owner-occupied mortgage. Our complete DSCR loans guide covers the basics.
Key Terms Defined
Cash-out refinance: a new loan larger than your current balance, with the difference paid to you in cash.
DSCR (debt service coverage ratio): monthly rent divided by the full monthly housing obligation: principal, interest, taxes, insurance, and any HOA dues.
Unpermitted work: construction, conversion, or structural change done without the building permit the local jurisdiction required.
Gross living area (GLA): the finished, permitted, heated square footage an appraiser counts toward value.
Hosting history: documented past short-term rental performance, shown through platform statements or bank deposits.
Seasoning: the waiting period a lender wants between buying a property and refinancing it.
Does Unpermitted Work Automatically Block the Refinance?
No. Nothing federal bars a refinance because of unpermitted work. DSCR loans are not agency products, so each lender sets its own collateral rules.
For contrast, the conventional baseline is “disclose and assess,” not “reject.” The Fannie Mae Selling Guide tells appraisers to comment on the quality, appearance, and market-value effect of additions made without permits. Fannie Mae’s own appraiser material adds that a missing permit alone does not make a property ineligible. Those are conventional rules, not DSCR rules. They simply show that “unpermitted” does not mean “dead on arrival.”
In the DSCR world, lenders layer their own overlays on top. Programs differ on how they treat unpermitted space, and no published figure exists for how much value gets haircut. Anyone quoting you a percentage is guessing.
How Underwriting Treats It, Step by Step
Step 1: The appraiser inspects and measures. Unpermitted work is usually caught by comparing the physical home with county or tax records. A square-footage mismatch, an odd layout, or visible quality problems will flag it. Space with no permit trail is often treated as non-GLA, meaning it adds little or no value. That is practice, not a published rule, and it varies by appraiser.
What helps an addition get counted? Appraiser commentary points to work that is well built, common for the area, supported by comparable sales, and insurable. Comps matter. If similar homes nearby sold with similar space, the market may accept it.
Step 2: The appraisal sets value, and value sets leverage. If the appraiser excludes or discounts the work, the lender underwrites the lower number. Your loan is a percentage of that value. So cash-out shrinks faster than the value does, because the percentage cap applies to a smaller base and your existing balance stays the same.
Step 3: Short-term rental income is documented separately. The appraisal does not prove your nightly income. Fannie Mae’s appraiser update notes that the Form 1007 rent schedule needs monthly-lease comparables and cannot be used to estimate a nightly fee for a short-term rental. HousingWire reports the form was not built to support this income and describes a narrative addendum as the workaround. McKissock, an appraiser-education provider, says the final income determination belongs to the lender, not the appraiser.
So lenders look to hosting history, platform statements, bank deposits, or a third-party market data report. Short-term rental files usually expect about 12 months of landlord or host experience, and a cash-out refinance leans on in-place performance, which makes that history central.
Step 4: The legality check. The lender asks whether short-term rental use is allowed at this address. Proof can include a license, a zoning letter, and HOA rules. Short-term rental rules can vary by city, county, HOA, and property type, so confirm local rules before relying on projected rental income. If permission cannot be shown, the file may fall back to long-term market rent, which is often well below nightly income.
Step 5: Income from unpermitted space is generally excluded. The usual case is a garage conversion or ADU (accessory dwelling unit) rented as its own unit. Qualifying then rests on the main house alone.
Program Numbers That Frame the Math
These are typical ranges from select lenders in our network. They are not commitments to lend, and every file is underwritten individually.
| Factor | Short-term rental cash-out |
|---|---|
| Maximum leverage | Up to 70% LTV on short-term rental collateral |
| Minimum credit score | Typically 640 or higher |
| Coverage floor | 1.00 on refinances on select programs |
| Hosting history | About 12 months expected |
| Loan size | Up to $3,000,000 on standard programs |
For comparison, standard long-term rental cash-outs top out around 75% LTV. Short-term rental collateral gets the lower 70% cap. Reserves vary by lender, leverage, and loan size, and about six months of PITIA (principal, interest, taxes, insurance, and association dues) is common.
One caution about the coverage number. Clearing 1.00 is not the same as positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the calculation.
The 1.00 floor applies to the standard refinance programs in the table. Some select lenders in the network will consider a file below that line, but that is a separate path, and it generally means a lower loan-to-value and different terms.
Which Kinds of Work Carry the Most Risk?
Not all unpermitted work is equal. Cosmetic, safe work that does not change how the home is used usually draws, at most, an appraiser comment. Additions, garage and basement conversions, and structural, electrical, or plumbing changes sit at the risky end. One California source, LA Construction Compliance, says title policies there exclude code violations, so title insurance will not rescue a bad permit situation. Treat that as an illustration from one state, not a national rule.
| Scenario | Likely effect on the file |
|---|---|
| Cosmetic update, no change of use | Often an appraiser comment only |
| Unpermitted deck or minor structural work | Possible value discount; lender overlays vary |
| Converted garage or basement, not rented separately | Space likely not counted in value |
| Rented unpermitted unit or ADU | Unit income generally excluded from qualifying |
| Permitted ADU in a city that restricts nightly stays | May count only at long-term rent |
Those outcomes can stack. A lower appraisal, a 70% cash-out cap, and excluded unit income can turn a planned cash-out into a smaller cash-out, a no-cash-out refinance, or even cash to close. When the permit trail is murky, it is common for brokers to see the cash-out amount, not the approval itself, take the hit. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
A Worked Example
Say you own a short-term rental purchased at a price that has since appreciated. You expect the appraisal to support a certain value, and you plan to borrow at the 70% cash-out cap. A converted garage that you rent as a separate guest suite is unpermitted.
The appraiser leaves that space out of GLA, so the value comes in lower than you planned. The same 70% cap now applies to a smaller number. Meanwhile the lender drops the garage suite’s income from qualifying. Your coverage ratio, which looked comfortable at around 1.3x with both units, might fall toward 1.0x on the main house alone. That combination can shrink cash-out, push the file toward a lower-leverage structure, or leave it at a no-cash-out refinance.
These inputs are modeled assumptions to show the mechanics. They are not market data. Your outcome depends on the appraisal, the lender, and the property.
What Are Your Options When the Work Is Unpermitted?
Four paths come up on these files:
- Proceed as is. Works when the work is minor, common for the area, and not producing counted income. Expect the appraiser to comment on it.
- Reduce the ask. Plan around the lower value and the main house’s income only. This keeps the loan simple.
- Fix first. Permit and document the work, then reapply. Legalization can be slow and costly, and costs vary widely by jurisdiction, so get local quotes before committing.
- Delay or restructure. If the file is thin, build more hosting history or wait for the license situation to clear before refinancing.
BRRRR and rehab investors should check permit status before the refinance, not after. Your after-repair value assumption does not set the loan. The appraisal does. And the condition follows the property to resale, to insurance claims, and to the next lender.
Insurance, Title, and the Misconceptions
Insurers often cover the structure regardless of permit status, according to Custom Home. But standard homeowner and landlord policies typically exclude short-term rental activity. You generally need a specialized short-term rental policy or endorsement. Liberty Mutual’s ADU page explains the difference between homeowner, landlord, and short-term rental coverage.
A few myths worth clearing up:
- “Unpermitted work kills any refinance.” No. Lenders set their own rules, and the conventional baseline is disclosure plus a market-value assessment.
- “If it looks professional, it counts.” Appraisers rely on records, permits, and market evidence, not looks.
- “The appraisal proves my short-term rental is legal.” It does not. License, zoning, and HOA proof are separate.
- “The 1007 will show my nightly income.” It will not. Multiplying a nightly rate by 30 does not make it valid.
- “All DSCR lenders do short-term rentals.” They do not. Some decline them, some require full hosting history, and some accept market-data projections.
Provider Types, Compared Neutrally
When people ask for “top providers,” they often mean provider types. Here is how the categories differ on this problem.
| Provider type | Unpermitted work | Best fit | Trade-off |
|---|---|---|---|
| DSCR lender | Own overlays; varies by lender | Investors qualifying on rent | Short-term rental rules differ widely |
| Portfolio bank | Often strict on permits | Strong personal income files | Heavy income documentation |
| Hard money or bridge | Flexible on condition | Short-hold or fix-first plans | Shorter terms, higher cost |
| Jumbo lender | Conventional-style appraisal review | Larger owner-style files | Rarely suited to nightly-rental income |
A broker’s job is to match a scenario to the right category and then to the right lender inside it. That means asking what the appraiser is likely to do before you submit, not after.
What to Prepare Before You Apply
Assemble these first:
- Permit history or a records search for the address.
- Contractor invoices and photos of any work.
- Platform statements and booking history.
- Your short-term rental license or zoning proof.
- Insurance declarations showing short-term rental coverage.
- Entity documents if the property sits in an LLC, subject to lender program eligibility.
Disclose what you know. Concealment risks a denial and creates problems later with insurers and the next buyer.
Frequently Asked Questions
Can I take cash out on a short-term rental with an unpermitted addition?
Often yes, though the amount may shrink. The appraiser may exclude the space from value, and a lender may exclude any income it produces. Short-term rental cash-outs are capped around 70% LTV on that collateral, so a lower value cuts the proceeds directly.
How does a lender find unpermitted work?
Usually through the appraisal. The appraiser compares what they measure and see against county or tax records. A square-footage mismatch or an odd layout flags it.
Is a short-term rental license the same as a building permit?
No. A building permit covers construction. A license or zoning approval covers the rental use. A lender can check both, and either can reduce counted income.
Do I need tax returns?
Qualification runs primarily on property-level rental income covering the payment, subject to lender guidelines. Hosting history is the main document for short-term rental files. Specific documentation requirements vary by program.
Should I permit the work first or refinance as is?
It depends on the type of work, the income it produces, and your timeline. Minor work common in your area may be fine as is. If the unpermitted space drives your income, fixing first may be the cleaner path.
