i would try and keep your house if i was you and rent it while your travelling ,then if it don't work out for you which is often the case or if you eventually get tired of it which again is often the reality for a lot of people you haven't burnt all your bridges and there's no better thing than bricks and mortar for an investment and time fly's as you get older you don't want to end up with f**k all and a battered camper ,just my thoughts
