The mortgage dates from 1983. The estate’s legal paperwork that she prepared dates from 1999. That part is consistent.
The part that the GP author didn’t explore deeper is that it appears she took over the estate and effective cut off all of her 7 siblings from receiving any benefits. I suppose you could argue that it was indeed hers alone (thanks to being named on the mortgage) once her father/”husband” passed, but of course none of that seems to have been a subject of probate.
Get a load of the mortgage company - Kadilak. What, they can’t spell Cadillac? And they used a P.O. Box address instead of a street address. Red flags all over this thing.
It crossed my mind that maybe there are 10 years of SS checks that were cashed after father/husband died?
