My first impression is that renting it out would be better for you. The transaction costs of selling now and then buying something when you return would not be worth it, especially if you still really like living there and would like to return in a year. Also think about storage costs for your stuff if you sell it, rent costs when you coming back and need to find a place etc... I also wouldn't do business with your friend in that situation, especially if he can't afford it. Find market rate renters, take deposits and hire a professional management company to look after it while you are gone
