I think so many bars are being rented at the moment because the owners can’t sell them, but they want to get out because they arent making much money!! Running an English bar, in my experience, is one of the less lucrative ways of making a living in Spain, especially in the current climate… You’d probably do ok in the height of summer (that is July and Aug) but there’s also the rest of the year to think about. Also, do you really want to be stuck in a bar when there’s that lovely sun to enjoy ?!
Good luck anyway, whatever you decide to do..
