I haven't gotten any calls yet but will definitely work with all my tenants (they all happen to be pretty solid) that have issues. Also I don't believe anyone mentioned A class people is better than B class or B is better than C. It is just easier to pay the bills (most of the time) for A and B class than C class. My A class is filled with engineers & doctors. B class is teachers and mostly working professionals. I don't have too many I would classify as C but they are more blue collar/restaurant. People wise...they are all great. But their ability to pay rent in a time like this will vary significantly. A class can dip into savings, retirement, CC, friends and co workers and probably come up with the rent. C class might find that difficult.
I think at the end of the day, we are all just people and hopefully everyone can work things out in the end. It is real estate investing after all...not real estate money tree. This is a true test to see if you've built a good system that didn't' over leverage with healthy reserves.
