You can sell your Florida house with an unpermitted addition through Cash Flow Deals. You choose between the Fast Cash Offer, where we buy your house as-is and close, and the Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. An unpermitted addition does not stop a sale by itself. It does mean the added square footage usually will not count toward appraised value, and most lenders will not fund a buyer's loan until the work is resolved or excluded.
| Factor | Traditional Listing | Cash Flow Deals |
|---|---|---|
| Timeline | FHA lenders in particular pause or deny funding once an appraiser flags unpermitted work, often forcing a relist or a search for a buyer who does not need a mortgage; VA and conventional lenders are generally more flexible if the space meets safety standards. | You choose the Fast Cash Offer or Premium Cash Offer. The number is agreed before any work starts, and it changes only if you agree. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens. |
| Repairs | Buyer may demand the addition be retroactively permitted, brought to code, or removed before closing. | Work is re-costed only if something structural is found; otherwise the price holds. |
| Fees / Costs | Commission is negotiable since the Aug. 17, 2024 NAR Sitzer/Burnett settlement, plus the seller often eats the cost of retroactive permitting or a price cut for the missing square footage. | On the Premium Cash Offer, Cash Flow Deals is paid as a separate line item on the closing statement, not a markup on price. No listing commission to Cash Flow Deals on the Fast Cash Offer. |
Why an Unpermitted Addition Complicates a Florida Sale
An unpermitted addition is work done on your house, a room, a garage conversion, an extra bathroom, that was never inspected and signed off by the local building department. The square footage exists, but the county's record of your house does not show it. With Cash Flow Deals, you can compare the Fast Cash Offer, where we buy your house as-is and close, with the Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. You choose which offer fits your situation, with the unpermitted work disclosed upfront.
How an Unpermitted Addition Affects Appraisal and Financing
Appraisers typically will not credit unpermitted square footage toward a home's value, even when the addition was expensive to build and looks finished. FHA lenders in particular will not finance a property with known unpermitted work until it is resolved, which usually means the buyer either pays without a mortgage or the seller fixes the permit problem first. VA and conventional lenders are generally more flexible if the space meets safety standards, but the FHA gap alone shrinks the pool of buyers who can even make an offer, and it tends to invite lowball numbers from the ones who do.
What Florida Disclosure Law Requires You to Tell a Buyer
Under Johnson v. Davis, the Florida Supreme Court's 1985 ruling, a seller must disclose facts known to them that materially affect the property's value and are not readily observable to the buyer. An unpermitted addition, along with unpermitted electrical, plumbing, or roofing work behind it, fits that description. Florida's First District Court of Appeal confirmed in Rayner v. Wise Realty Co. of Tallahassee that selling a house 'as is' does not waive that duty. A buyer who signs an as-is contract still has not agreed to eat an undisclosed unpermitted addition they never knew about.
Cash Flow Deals' Process for a Property With an Unpermitted Addition
With Cash Flow Deals, you choose between the Fast Cash Offer, where we buy your house as-is and close, and the Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. Here is how your process works: 1. Request your walkthrough and disclose the unpermitted addition upfront. 2. Compare both offers. The number is agreed before any work starts, and it changes only if you agree. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens. We cover repair costs, and we figure out a way, so nothing comes out of your pocket. With Premium, only what your buyer's lender requires gets fixed, with repair costs settled from the sale proceeds, from our share rather than your number. With Fast Cash, we buy as-is, with no repairs for you to make. 3. If you choose Premium, you sign with us and give us permission to bring a buyer in our place. Your home may be listed through Silver Door Realty, a licensed Florida brokerage, with a licensed agent and scheduled showings. Your buyer signs a new contract directly with you; title transfers once, directly from you to that buyer, whose lender funds the purchase once financing conditions are met. 4. On Premium, Cash Flow Deals is paid as a separate line item on the closing statement. If your buyer's loan falls through, that is our problem, not yours, and you can still take the Fast Cash Offer at its own number or choose the Premium Cash Offer if financing can be resolved.
What Happens If the Addition Turns Out to Have a Structural Problem
For your Fast Cash Offer or Premium Cash Offer, the number is agreed before any work starts, and it changes only if you agree. The one exception: if something structural surfaces that was not visible or disclosed before we signed — foundation issues, hidden moisture, old wiring, cast-iron drain failure — we re-cost it and bring the number back to you. You decide. You can walk away. We disclose what we know at offer time so this almost never happens. Hidden conditions can include foundation issues, hidden moisture, old wiring or cast-iron drain failure. We disclose what we know at offer time. For your unpermitted addition, a foundation tie-in or wiring problem discovered once the work gets inspected is brought back to you for review and any agreed change, rather than buried inside a lower number at closing.
Common questions
Do I have to disclose an unpermitted addition when I sell my house?
Yes. Under Johnson v. Davis, Florida sellers must disclose known facts that materially affect a property's value and are not readily observable to the buyer, and Florida courts have confirmed an as-is sale does not waive that duty.
Will an unpermitted addition kill my buyer's FHA loan?
It often will unless the work is resolved or excluded from the valuation first. FHA lenders in particular generally will not fund a property with known unpermitted work, while VA loans are more flexible if the space meets safety standards.
Does the added square footage count toward my home's appraised value?
Usually not. Appraisers typically exclude unpermitted square footage from the valuation even when the addition was expensive and looks finished.
Can I sell without fixing the permit issue on the addition first?
Yes, you can sell to a buyer who does not need financing, subject to disclosure. With Cash Flow Deals, you choose between the Fast Cash Offer, where we buy your house as-is and close, and the Premium Cash Offer, where a pre-approved FHA or conventional buyer we already have, ready to go, pays more and buys directly from you. A buyer relying on a traditional mortgage will usually need the issue resolved or credited before their lender funds. With Premium, only what your buyer's lender requires gets fixed; we cover repair costs, and we figure out a way, so nothing comes out of your pocket, with those costs settled from the sale proceeds.
