As a realtor, I can tell you that if you list at a high price, you can both be on the market and be in very little danger of selling. Especially today. The work of keeping the house up to showing condition will largely fall on her, since she is home most of the time. I would recommend pricing it slightly above market comparables, and then let it sit on the market for a while. She may tire of keeping it clean and decide to take it off the market.
