Gotta live the dream, Cliff.
Don't know which option is best but makes sense to me to keep your home. Rent it out for a year.
Buy a unit used. Fairly new. Be patient. A great deal will present itself. The rent covers all costs
Give it a whirl.
If it's not for you, you can do plan B.
But at least you tried.
Livin the Dream.
You don't want regrets.
