u did not state exactly where her home is or its size. Often, poeple can economically save their home by using it for different reasons; likeputting in an assisted care facility.[might be ideal for her if you canhelp coordinate.]or she sells her house to you. With that cash, she pays off her debts totally.Then, you give her a life estate. When you have paid off that mortgage, you then, buy whatever other home you want. Everyone wins and she can life in the home forever.YOU did not state where you want to buy your new home in 2 yrs orwhat you wanna pay for it ..but I am available to guide you [both]
