Just make sure you list it as a contingency in your contract so if it does have radon you can have the seller pay for the mitigation system or have the right to pull out of the sale. Many areas have radon, call your health department. Where I live there is a lot of shale so most homes in my township have radon and a mitigation system. IMHO if the area if it is not common pass on the house due to resell. If it is common u won't find a house without it. -- This post is made with meat biproducts.
We put a bid on a house today for a house that has a mitigation system in place. We will be scheduling a Radon inspection for $100 once everything else gets signed (amongst other inspections). -- A government big enough to give you everything you want, is strong enough to take everything you have. -MLK
