By all means have a plan. Full timed for five years then bought another house in 09. I made enough from the sale of my house in California in 05 to pay cash for my RV, buy another house when we were ready and retire at 52. Would not have been possible otherwise. Only you'll know if it's doable. I don't think you'll see home values as high (ridiculously over valued) as they were in 05 again if your selling a home. Perhaps a home base park will work as well for you. Look into the Escapees club and care center.
