Is there a remedy that we can remove equipment.

Rather than try to force that on him, I would like to know what a reasonable remedy would be for breaking the lease.

One way to remedy this is to read, listen, read, listen, read and watch everything you can for free about Real Estate. 

Many foundation repair companies (and some pest control) offer services for crawlspaces, to include mold remediation, encapsulation, etc.

As part of the renovation, all of these were remedied however the violations were not cleared as I suspect the renos were done without the full permitting.The purchase agreement had a requirement to clear the violations prior to sale but the Seller and I agreed a fairly substantial seller credit to clear the violations as it was recognized there were risks around the renovation work and potential non compliance with permits that I may have to remedy.

I use a remediation company and he typically sets up 4 to 6 machines.

After the tenant moves into your home, things become your responsibility.As a more immediate remedy, try to do away with those trial leases.

We remediated what could be found sent pictures jumped though all the hoops and they still said they weren't going to renew.Got a new policy that has a 25k deductible just to make the premiums tolerable.

She went ahead and hired a pest company, signed a contract for the next 18 months, to come and remedy the problem.

Even beyond those, I believe that I won't run into many vacancy issues.Despite the sellers opinion that the property needs "no work", I believe there are a number of things my partner and I would like to remedy.
