I doubt that; and she will only owe the mortgages if they were on the house before Laci died.
The mortgage was a pretty hefty one as I remember. They had refinanced it to put in the pool. Ron couldn't even afford a little fishing boat (he just wished for one) so doubt he and Sharon could assume that debt. So who do you think would get stuck with the second mortgage? Scott's parents took it out with another party IIRC.
