Does she own the land free and clear? If so I think you have her get a loan against it then use that money to pay for new house and you happily make loan payments.. should the wheels fall off you simply go away and she does what she has to do.. asking them to take some risk and responsibility but no financial obligation is fair.. she trusts you and you trust her, easy peasy-maybe!!
and Biden has done such great things? He’s only made the wealthy more wealthy and he can barely remember his own name.. if you can find someone better than Trump then go for it but it’s not drooling Joe for sure.. please keep your uneducated nonsense off here..
