Second Home - Sell now or wait?

My grandmother (IL resident) owns a condo in FL (second home) that has no mortgage and has a month-to-month renter in place. It is willed to her trust.

She will be moving to NC to live with me and she has some medical expenses upcoming. She has a retirement investment fund she could draw from, but it might be easier to sell the condo and keep a sum of cash available from the sale to use instead.

Tax penalty-wise, is it more advantageous to the estate for her to sell the condo now or to keep it and continue to rent, using her retirement investments for the medical expenses instead? We are trying to make an appointment with her financial advisor this week but haven't gotten a call back yet, so I thought it might be nice to get some extra guidance before we speak to them.
