Searching local records, I see that in 10 years, only one property has not been redeemed, and it was donated by the purchaser as wetland park space.

Just be sure to get a satisfaction document signed and recorded to show this lien has been cleared when this gets paid off.

My title company said they do lien searchs only outside of the title insurance, no death records search or probate or anything.

Would we need to wait a year or two to build enough of a track record with lending?

I have been manually researching county records for a while now, but wanted to see what the BP community recommends using for this.

In many of them, there is not a relative posted on the property records anywhere and doing obit searches seems like there may be no next of kin.

Sounds like you have done that in record time.

The only knowledge of the property/condition is from public record and just driving by.
