Will you be working? If so then a home near your work or a reasonable commute would make sense.
Do you have friends or family that you would like to be near?
Will you be a snowbird or part time resident? Then you might want something resort like.
What activities do you like? Dining, Shopping, Golf, Tennis, etc. You can look for homes in areas that have the type of amenities you need.
