Mendy's Original Take

From the Mendy Realty archive, first published by Mendy Lipsker.

In a recent mailing, DovBer Kahn of Kahn Home Inspectors sent the following emphasizing the dangers of radon. Like carbon monoxide, radon is odorless, tasteless, and invisible, but just as deadly.

When purchasing a property, it might be a good idea to see if the owners/sellers have had the property tested for radon. If you are selling your property, having the results of a radon test would assure your potential buyers that you have been a consciousness owner and taken care of the property.
