Anyone ever successfully negotiate a fee for the retrieval of tax or mortgage foreclosure overage accounts, for a previous property owner?

For reference, I was using the following sites to retrieve the data: https://www.deptofnumbers.com/... http://www.city-data.com/

If he has a mortgage on that house it's recorded somewhere and is easily retrievable.2.

Sheriff deputy said I could either store it or take it to the dump if it wasn't retrieved.  

One day one of the adult children came over, opened up the garage door, retrieved a shirt on a hanger, closed the garage door, and got back in her car and drove off.The father had moved out of the house and dropped by one day to tell us his now ex-wife and the rest of his family had drug issues, were detached from reality, and couldn't accept the fact that the house was sold and they had to move on.

Very efficient.They came back 2 days later to retrieve their belongings.

“Katy Christian vacated the house prior to Hurricane Beta.Unfortunately she contracted Covid 19 was hospitalized.She is now in quarantined as eveyone who has lived in my house since March.We are testing weekly and sanitizing everything weekly.She and I were not in your house before or after she tested positive.Unfortunately some of her furniture could not be retrieved because of the Virus.Remains in your home and must be forfeited.We’ve offer it for free for pick up.

I was able to get my bottom tenant's deposit back after the deal closed but was unable to retrieve the deposit for the upper tenant.2.

If a tenant accidentally throws something away and later wants to retrieve it, they are only digging through their own trash and not the neighbor's pile of dirty diapers and cat litter.

I thought of just classifying them all as mortgage payments (creating a new type of account), and then at EOY to take the mortgages' statements and retrieve the amount of interest paid, along with prop taxes and insurance paid from escrow accounts.Is there a better way of doing it?
