When meeting with buyers for the first time, we explain what to expect from the home buying process. One of the things we go over is inspections, radon being one of them. In our area there is a good chance that there will be elevated radon levels upon testing.
When we look at houses, radon systems are looked at as a positive feature not only because it is less likely radon will be present (we will still suggest a test be done) but also because it indicates the seller understands the issue and has been proactive in dealing with it. Having a system present has never been a factor to decrease the of value a home in this area.
A radon mitigation system can be a great selling point to a home. Obviously, every home can be victim of radon, but knowing there is a pro-active measure in place is a great feature. I agree with you Donna!
Most likely yes. That is a situation that although remedied, is not cured and causes people concern. Anytime you have a health concern, unless it is totally eliminated, your home will be at a disadvantage compared to a similar home without the concern.
