This is the dillemma I am in. There was an unknown water leak in a pipe between walls at my primary residence ( betw master bathroom and a bedroom. I only got aware something was wrong when the adjacent bedroom wall in my child's room started to "have bubbles"..Called a plumber immediately. They fixed the pipe. Insurance came out, refused the claim " it had been an ongoing problem based on the mold pattern in the crawl space". Sorry for long post..  I called 2 mold specialists to get quotes. Lower one was 5k. I don't have that available at this time....single mom raising 3 kids.

I do however have a paid off property that I have would like to sell to mediate the above situation. The tenants in this particular property have 3 months left on their lease. I met an agent and I would  like to list.( ran out of options) ... Don't want my kids sick. How do I approach the tenants about my listing this property, showings? I hate to have to do it, but I see no other choice at this point... 

Sorry for the long writing above.
