Tenant signed lease in August for second year in house, no probs at all last year. Agreed to increased rent of E50 euros a month. This extra E50, over and above the E800 of last year, (its a lovely brand new perfect 4 bed house in a large midland town on good estate) has NOT been paid in either August or Sept. He has been contacted --said he instructed his bank, was contacted again last week 3 weeks after first time, and says he will go right in to his bank again to tell them. What option is left to me if he does not pay, any ideas please? Thanks in advance.
