Radan Test- Help!

[Anthony Pelaez]

Hello fellow investors,

For some context I was going to close on a house Today on Feb 23rd. Our inspection report came back on Feb 21st and the home tested positive for Radan. Anything above 4 is bad and our report came back at 46.4 which is extremely alarming and dangerous. The builders first response was that we had to deal with it + get retested if we wanted to and if we wanted to push closing back we would have to pay $500 a day. To which made the decision to back out, and our realtor sent a communication to the builders. Minutes after we hear from the builders saying they will pay for the retest and they will let us push closing back without a cost. At this point it was too late for us. 

Some questions I have:
- Are mistakes common on a Radan test?
- ⁠The builders want to charge us $7,500 for backing out. This was included in the initial contract we signed when we put the $1,500 deposit. We want to fight this expense because we aren’t backing out just cause, we are backing out for a serious reason. What do you suggest?
