A big factor when considering the dangers of randon is where you're at.
Before moving to Florida 18 years ago, I lived in Southeastern Pennsylvania. Because of the presence of coal in the rock strata throughout much of the area, radon testing is often done. Sometimes I think it's as common to have radon tests there as it is to have termite inspections here in Florida. These tests are taken very seriously All radon test records are kept on file with the state of Pennsylvania and must be disclosed to future Buyers.
However, one factor which I don't believe gets enough consideration is how airtight the home is. Older homes can be very drafty and poorly insulated. A home like that is not going to present the same potential for allowing radon buildup inside as a newer home which may offer less possibility of air leaks.
Also, the amount of time people spend in a home over a lifetime is a factor in whether randon affects them as well. In our mobile society, I'm not sure many of us stay in one home for 20 years anymore. Does that mean you shouldn't test for radon? Not at all. Buyers should conduct whatever tests and inspections they feel are needed to be comfortable with their purchase.
So you do have the house on the market? Your letter doesn't actually say that. Your brothers are owners and you can't sell it without their signatures. If they don't want to sell it, you can't do it. Why not sell your share to your brothers and move? To you, it's the same end result as if you sold the house.... more
