Hey guys, need some input from those of you who have experience. Recently I had some viewings to rent out my condo unit. Got some interested foreign students offered to rent for 3 years. I have usually done only 1 year so far. On one hand seems ok to me because I don't need to worry for the next 3 years. But on the other, if there are any problems, also means locked down for 3 years. (They seem ok lah when meeting them) Also, cannot raise rent.

Any advice?
