Due to CO issue I had to ask the tenants to vacate the property until I was able to remedy the situation.

What else does the property need besides a roof and mold remediation?

There is your incentive, not my problem, breach the terms of our note and face a storm of collections under the remedies provided within the note.Statistically, my triggers are a very, very small portion of the assets I have managed but the key concept there is, trust me my friends, I know my tools better than you.

My only remedy if they didn't agree to correct the errors would have been to sue.

It can be remediated, but no way to give you a cost.

Did you end up closing on the home and performing any remediation on the issue?

After all, I lived in a house that needed to be remediated which it was successfully.

By my remedial investigation, I don't see more than 60-70K in work here.

I had to do a double take on that to confirm you are in the U.S.A ... and here I thought only Canadian municipalities could miss an effective solution to a situation by such a wide margin.Taking away affordable places to live is going to remedy drug use issues?
