Suggest you put a month or two aside and come over on an extended holiday/inspection trip......that way, anywhere that catches your interest ,at least you can sit outside or nearby and get an idea of the foot-fall/passing trade/plusses and negatives of your potential purchase.......without really doing your homework as regards licences,staff costs,stock replenishment,opening hours,profit and loss calculations ,rent retentions ,community charges,income tax bills and the new 7% IGIC tax on everything,etc.(not to mention your residencias/empadronamientos/social security registration costs to you personally) then you risk ´´falling at the first fence´´as many do here.
As I said best of luck with the average working week of 12-14 hours per day,7 days a week......all for a measly wage initially (if at all) .....sorry to sound so negative but that is the reality of opening a new business here at the moment.....and the fact that ,on the whole, nearly every person in authority who you will deal with will speak ONLY Spanish to you....makes sorting things out really difficult.
If it were me.....whatever you have been quoted to buy, TRIPLE (at least) that figure in order to begin trading
AND ensure you keep enough money set aside to leave if it all goes ´´bottom-up¨´
PS........If the business was successful ....why is it up for sale in these difficult times????? not every bar owner is up for retirement
