One small answer as to the process ...

I noticed that the Borough had to do a second public notice (same material, week later).  I also noticed that the fine print reads that up until the property is auctioned, the owner can pay off the amount listed including any interest accrued but only by cash or certified check.  Cash is no big deal if it is easy for you to get to Borough Hall and you have no qualms about carrying around a large amount.  Certified checks require a visit to a bank, which if you are already having problems because the signer is ill, in a nursing home, or this is part of an estate can be really problematical.    Especially since you can be charged more than is listed on the public notice as there may be more interest yet.  Then imagine being out of town or worse, out of state.
