Since many of us may have to face this, I am trying to understand the situation:
1. Is she not well? Since you say she is only 60, hence can’t get Social security/medicare. I am wondering how you are planning for healthcare? As an aside, if she is in good health, might it be a good idea for her to get some employment to get some health insurance. That will also ease the cash flow. It will help her a lot if she can complete the minimum credits for social security since she has such a long retirement to face.
2. Since big bucks (i.e. losses) are involved in home selling/buying in these unstable times, (a) Why can’t she continue to live in AZ (b) How about renting out AZ home and renting a small apartment here. The cash flows may be closer to match.
