I did not know that the Seller would be providing all money necessary to remedy the deferred maintenance. 

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 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. 

We are talking roof, electrical, termite tenting, some stucco remediation, internal cosmetics, kitchen, etc.

In my initial networking leap forward here I'd like to offer up my knowledge of mold remediation, fire and water damage, carpet cleaning, and general contracting.

If your real estate agent has no knowledge of this type of form, they should still be able to contact the listing agent in order to have the smell remediated.
