Hi! Thank you so much!
Would it be possible for in the less than 3 year time frame required for us to sell her the house and use our equity as her home loan if you will? Aka - take her down payment in cash and then accept mortgage payments with an agreement that she will refinance at some point if/when the interest rates become reasonable again and pay off our "loan" to her. The interest rates are mainly what would make the place unaffordable to her right now. She will have a down payment because she needs to sell her current home in order to move back "home".
