As a Florida Mortgage Broker and Investor, I know how easy it is to sell property FSBO, it ain't rocket surgery!  

My wife had a surgery last year that was paid for in cash.

There is no remedy to that one.

Just stay true to your investment criteria and make sure that the numbers work when trying to remedy these issues and you should be ok 

And many fly by night investors came in to fix and flip without proper flood remediation. 

Just this year walked away from a deal when the seller would not remediate radon.  

I have my money tied up in a purchase that I have been in too long due to my appendix and needed time to recover when it ruptured.Now back and fully recoved from the 3 surgeries.

I might be phrasing it incorrectly- Alliance Environmental did the tests that showed we had asbestos in the popcorn ceilings and they are a company who can provide remediation, but they are not the company who caused the problem.

Apparently remediation is going to cost around $2,000 with and if I want to prevent it in the future, a $100 / month servicing contract for bedbugs. 

She will be needing surgery, and then will be stuck at home and to a wheelchair for 2-3 months after surgery.
