I guess if she can afford the mortgage on her own income, and she's not planning on any alimony, and her debt level is low, perhaps she could get a mortgage. In my case, the bank told my XW that she had to wait for a settlement, and I don't think they even looked into the details. Although since her earning power is pretty low they might not have looked very far.
As to her comments, she is clearly trying to guilt you into giving her a better deal. Ignore her comments and listen to your lawyer. Stick to your guns, your mantra is "let the judge decide, then."
