If you're buying the property for any purpose other than flipping then ROI from the sale of the property itself shouldn't be a serious consideration. Either you're living there and sale doesn't really matter so long as you don't get shafted too badly whenever you do sell or you're renting or using it commercially in which case the cost to acquire is sunk and the returns from that should more than make up for change in value and whatever you get from a sale at the end is just a bonus.
