Normally I don't socialize with my tenants but they were paid up for the next 6 months so I decided to take him up on it.We had such a good time we decided to make a weekly tradition of going out for wings and by the end of the lease we had become such good friends not only did we get wings weekly but they also invited me to go on vacation with them and they invited me to be a part of their wedding at an inclusive resort.They only rented from me for 14 months and they got a heck of a deal but they are now lifelong friends.
