The sole remedy of the lender is the property.Now take the rest of the states and Texas in particular Mississippi for sure.. and you can foreclose get the asset then sue in court in a different action for a deficiency judgment and get a judgment against the home owner.. this is used when there Is in sufficient equity to protect the lender..

What are the steps I should take to remediate?

I personally think the remedy is E and O insurance and sellers disclosures.. just because its wholesaled does not alleviate the brokerage or seller from providing Sellers disclosures we all see them if we are doing for real real estate deals with licensed agents. 

We used the insurance company's preferred vendor for the smoke remediation… but we ‘made out like bandits’ on the painting / fixture replacement because they were wrote up  like $8,000 for the work and it probably took us 20 hours of work and $750 in materials to put things back together.  

Building finally resolved and remediated it this year and now i am selling the property.

My biggest mistake was thinking that I could lay down new LVP on the main floor of my last house hack, 1 month out of shoulder surgery and I quickly pivoted to a local professional.

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.
