This level should not be a deterrent to buying a home. In fact, any level should not be a deterrent to buying a home because radon can almost always be reduced in a home, and to levels below the EPA guideline of 4. Many times post mitigation tests are in the range of 1-3. The level of 2 would be a very good result for a home that had a mitigation system installed to reduce the level from a much higher number. As long as the issue is resolved in the real estate transaction, the radon level should not be a deterrent to buying any home. Achieving lower radon levels when the starting concentration is between 2 to 4 is not likely to be something a radon contractor would guarantee under typical conditions for a set price.
