The courts would likely require the PMC to refund the tenant and then pursue you for reimbursement -> that would cost them time & money IF it made financial sense to hire an attorney to chase you.Kudos to @Adam Bartomeo for getting this right!

If they say no, you might consider small claims court.

I say “even more than” because I saw one case where the sheriff’s sale was challenged in court, and the challenge lasted almost a full year - then add nine months plus deed recording time for the IRS to redeem.But those IRS liens do eventually expire (assuming proper notice was given).

---Send them a text confirming they are giving up claim to any & all personal possessions left behind and save their response.You could pursue them for damages in Small Claims Court, doubt they would show, but you would need their new address to properly serve them. 

If that looks good, I do my own google check and also look at local court records just in case something was missed by the background check.

if she can prove the extra payments i would take it to court.  

The general process is to go to small claims court to sue them for any additional damages.

Eventually I had enough money saved that I was able to buy 3 houses for cash in one year: a 2br/1ba 1000sf tired old rental for $37k; a 2br/1ba 1400sf home with several extra rooms for $46k from a court-ordered estate sale; and a 2br/1.5ba 1100sf repo I called the cat piss house for $37k (interestingly enough I have bought 5 houses for $37k, not sure why this number was successful).

It may require a formal court petition.There are most likely heirs, you just didn't go deep enough with ancestry to determine who they are.

The function of location can never be underestimated.
