Can I ever find a clean home?

[Guest guest]

My family has been out of our mold contaminated home for 15 months. We abandoned the house and all our possessions. We have moved our 3 young children 5 times in an attempt to find a "safe, clean" environment. We feel like we want to try to buy another house after being cooped up in tiny apartments. We were supposed to close escrow next week on a house but just got the mold testing back and sure enough, it too was positive for mold. That makes 3 houses in a year. Are all houses contaminated to some extent? I feel like I'm on a tight deadline because if we don't buy before our credit is ruined from the financial devastation of all this, I fear it will be a long, long time until we can buy. The reason I am so committed to buying is that I don't believe we can property control our living environment unless we own (i.e., remove carpet to control asthma, repair water leaks immediately, etc.).

I guess I am just discouraged. I really wanted this house but at the same time am terrified to get into another "Mold trap". Any recommendations from others who have been in my shoes?
