@Michael Sontheimer  Note buying a property and transferring the title to an LLC doesn't release you from it.

I was told by investors from my local REIA to get the seller who’s facing pre foreclosure to sign an authorization to release information form.

I asked that he release me from the lease agreement and move out within 10 days in exchange for $1000.

You cash flow it well and if tenant ever leaves you have great upside potential releasing to another tenant.

We limit our exposure by only lending 65% of the after repair value and if our borrower needs repair funds, we hold them in escrow and release them in draws.

The bad news is it won't be released until the spring. 

Because it was a residential tank, it was of a size considered "non-regulated" so a contractor was able to remove and dispose of it.In our case, there was no leakage so my client only paid the cost of the removal, which I believe came to a few thousand dollars.If there HAD been a release of oil, then the NH Department of Environmental Services would have gotten involved.

We have asked the buyers to sign a Mutual Release and they will not.

Perhaps you can consider making a monetary offer (like the security deposit) in exchange for the keys, and get her and her mom to sign a release of all claims.  

Has anyone who rented out condo units was ever mandated by the Condo building Property Management company to release the Credit Check and Background check information of their Tenants to the Building Manager as part of the tenant approval process for the lease?
