I rent to my ex , I did so in desperation when he had no where to go , We have a rental agreement now and my life is hell . He did 7,000 in damage before the lease and now is there girlfriend in tow and not following rules . ( No leaving cigatrette butts around , cleaning up after himself ) etc and he has not repaired all the damage and still lives there for cheap money when the rest of the city pays about 400.00 more a month for the same housing. So what can I do to get him out ? I live in Massachusetts
