Only time I'd be a landlord is if I had lots of cash and only dealt with middle and upper class folks... No low class people for me, no thank you
Orly?? Maybe as law enforcement but as a property manager / support-service person, i'm sure they have their own headaches. Some folks are so used to having subservient sycophants that you might never get any rest. Some of that entitled genre will push for every detail to go exactly their way with no room for reason or compromise.
I believe you earn your cash as a landlord, no matter the socioeconomic strata.
