It is difficult to say. Ask the mold experts there. Some friends of mine bought a house in Bonsall, California. REALLY nice house on hillside property in an exclusive gated community.
A hot water tank had leaked when the property was unoccupied, and by the time anyone noticed, there was mold.
They repaired it according to the guidelines. But, the house stood there vacant for months because everyone was afraid of the mold. They made a lowball offer to a "motivated" seller and got the house.
Fast forward three years. Yearly inspections have revealed that mold is not present, and there are no problems. This is in the hills north of San Diego, so would think it has a high humidity like Florida.
You just don't know. You must protect yourself with contracts that will have all mold problems paid for by someone other than you. Don't know if they actually do that, or once you buy it, it's your problem, and the seller evaporates. So, you have to ask yourself how bad you want the house. What is the worst case scenario on future mold. And whether you want to buy or pass.
Future disclosures may call for you to reveal the mold problem even if it has been cleared up. Not a good selling point ..............
