Selling a House With Polybutylene Pipes in Florida

Polybutylene pipe doesn't have to sink your sale, but it can sink a buyer's mortgage approval and your homeowners insurance quote. Cash Flow Deals is one option that locks a net price before an inspector even walks the property, so a gray plastic pipe from the 1980s doesn't turn into a renegotiated number two weeks before closing.
| Factor | Traditional Listing | Cash Flow Deals |
|---|---|---|
| Timeline | A buyer's lender can pause or deny financing once an inspector flags polybutylene, adding weeks or killing the deal outright | Net price locked before the pipe material even becomes a financing conversation |
| Repairs | A full repipe often runs several thousand dollars, and buyers or their lender may demand it before closing | Repairs including a repipe get scoped after the price is already locked in |
| Fees / Costs | Some insurers charge more or decline to write a policy with polybutylene present, which can scare off buyers before an offer arrives | Cash Flow Deals is paid as one line item on the closing statement, not a markup on the locked price |
What Polybutylene Pipe Is and Why So Many Florida Homes Have It
Polybutylene is a gray plastic pipe that builders installed widely in U.S. homes from 1978 to 1995 because it was cheap and fast to run compared to copper. Florida has a particularly large share of it, partly because of the construction boom that followed Hurricane Andrew in 1992, which fell squarely inside that installation window. The pipe became infamous because chlorine and other oxidants common in municipal water supplies react with it over time, making the pipe brittle from the inside out until it cracks or bursts, often with no warning. That defect led to a major class-action settlement in the mid-1990s, commonly known by the case name Cox v. Shell Oil Co., that gave affected homeowners a window to claim compensation toward replacement.
Why Insurance Gets Harder With Polybutylene in the Walls
Some Florida insurers decline to write a new policy once polybutylene is identified during an inspection, and others will renew an existing policy but exclude or cap water-damage claims tied to the plumbing. This is not a uniform rule across every carrier. It's a practice that varies company to company and policy to policy, so a seller who suspects polybutylene in the house should ask their current insurer directly what happens at renewal, and should expect a buyer's insurance shopping to take longer or turn up fewer available carriers.
Why a Buyer's Lender Can Complicate a Traditional Sale
FHA does not have a blanket requirement to repair or replace polybutylene piping just because it's present. But individual lenders, including some working FHA, VA, and conventional loans, can and do require a licensed plumber to replace it before they'll fund, based on their own overlay guidelines rather than a fixed government rule. That means a seller listing traditionally does not know whether polybutylene will become a closing condition until a specific buyer's specific lender weighs in, sometimes deep into the underwriting process.
Cash Flow Deals' Process for a House With Polybutylene Plumbing
Cash Flow Deals' Process: 1. Request a net-price walkthrough, so the pipe material gets addressed before a number is even discussed. 2. Cash Flow Deals confirms what's actually in the walls, since not every gray pipe from that era is polybutylene. 3. Cash Flow Deals locks the net price before deciding what, if anything, gets repiped. 4. Title transfers once, seller to buyer, on a set closing date that isn't waiting on a lender's plumbing opinion.
The Locked Price and the One Exception
Cash Flow Deals is a Florida real estate investor that locks in a net price for a seller's house before repairs are scoped, using a novation-based, flat-fee process arranged through its licensed FL brokerage partner, Silver Door Realty — not a traditional listing, and not a brokerage itself. That order matters most on a house where the plumbing itself is the risk. 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.
Common questions
How do I know if my house has polybutylene pipes?
It's typically a dull gray or off-white plastic pipe, often visible under sinks, at the water heater, or where the main line enters the house, and it's most common in homes built or replumbed between 1978 and 1995. A licensed plumber can confirm it in a short visit if you're not sure.
Will my insurance company drop me if they find polybutylene?
It depends on the carrier. Some decline new policies or add exclusions once it's identified, others don't treat it differently. Ask your specific insurer directly, since this varies company to company and isn't governed by a single statewide rule.
Does polybutylene affect FHA loans?
FHA itself doesn't have a blanket rule requiring replacement. But individual lenders processing FHA, VA, or conventional loans can require a licensed plumber to replace it before funding, based on their own guidelines, so the answer can differ buyer to buyer.
Do I have to replace the pipes before Cash Flow Deals buys the house?
No. The net price gets locked before repairs, including plumbing, are scoped. What gets repaired and by whom is worked out after the number is already set, not before.
