We've met many people who have been full timing for 5-10 years and don't have homes to worry about. Given that, if you are not absolutely sure you will love full timing like we do, then I would keep the house or sell the house and save the money in case you decide to purchase another house if you don't like full timing. Renting isn't usually an option and unless it's someone you absolutely trust I wouldn't leave my home with house sitters. I would start with trips about 4-6 weeks long to see how you like it, then increase to a couple of months trips. Bottom line is have a backup plan whatever you decide to do. We've been full timing for 4 years and do not want another home.
