Buying a House With Mold in Florida: What to Ask

Buying a house with mold in Florida

A mold finding on an inspection is usually a water finding. The question for a buyer is where the water came from, whether it's fixed, and what it will cost to remove what's left. Florida law also gives you some help from the seller.

What inspections find

Ceiling stains under the roof, a valley, a plumbing vent, or the attic air handler.
The AC closet: a rusted pan, a stained floor, a musty smell, growth on the air handler.
Behind and under sinks and the water heater: soft cabinet floors and stained drywall.
Flooring: lifted laminate, stained tile grout, a warm spot on the slab that suggests a hot water line leak.
Fresh paint in one spot on a ceiling. Worth a moisture meter reading.

A general home inspector notes these. If the smell or the stains point at something bigger, a licensed mold assessor can measure how far the moisture went. Mold inspection and testing.

What the seller has to tell you

Florida's Supreme Court held in Johnson v. Davis (1985) that a home seller who knows of facts that materially affect the property's value, which aren't readily observable and aren't known to the buyer, has a duty to disclose them. A known, hidden leak or mold problem is the kind of fact that rule is about.

Florida also requires a written flood disclosure for residential sales, at or before the time the contract is signed (section 689.302). The seller states whether they know of flooding that damaged the property while they owned it, whether they filed a flood insurance claim, and whether they got federal flood assistance such as from FEMA. In a metro where Hurricane Ian alone produced 1,829 federal flood claims, read it carefully.

What to ask before closing

What caused it, and when was that fixed? Ask for the invoice: roofer, plumber, AC contractor.
Was it remediated? By whom? Ask for the scope, the Florida mold remediator license number, and any post-remediation report.
Was there an insurance claim? For what, and was it paid?
How old are the roof and the AC? In Central Florida those two drive most of the water.
What does the flood disclosure say, and is the house in a mapped flood zone?

Then get a written price for any remaining work before you negotiate. Published national figures put a typical job at $1,500 to $9,000. What mold remediation costs.

Questions Orlando homeowners ask

Should I buy a house that had mold?

It depends on the cause and whether it was fixed. Mold that followed a repaired leak and was properly removed is a solved problem. Mold with no known cause, or a seller who can't show what was done, is a reason to get an assessment and a written price before you commit.

Do Florida sellers have to disclose mold?

Under Johnson v. Davis, a Florida home seller who knows of hidden facts that materially affect value must disclose them, which can include a known leak or mold problem. Florida also requires a written flood disclosure under section 689.302.

Can a house with mold be saved?

Almost always. Mold is a moisture problem with a cleanup attached. Fix the water source, remove what can't be cleaned, clean the rest and dry the structure. In Orlando that usually also means getting indoor humidity down. Whole-house jobs exist, but Fixr's whole-house figure is $10,000 to $30,000, far below the cost of the house.
