For example, I have bought a property in an undesirable area, and noticed that the rent and value hasn't changed much.

The following night at 1am I was awakened by sheriffs pounding on my door & was arrested for trespassing.

When I hear "affordable" I always think, undesirable since price is always based on supply and demand.

Look at SF  Portland and Seattle.. big movement back to the burbs because of companies leaving. now they are leaving because of defund the police and homeless and other social issues have made living there undesirable to many..

I've been pounding the table on Detroit since I figured it out in early 2019. 

Less inventory= better chance the seller will tell you to pound sand if you try any of the above.

I wouldn't even return the cleaning fee to be honest, I'd politely, or maybe not so politely, tell her to go pound sand..Rain.

An owner brings in a 20-pound dog for a rabies vaccine.

The property is extremely mismanaged and the tenants are quite undesirable. 20 of the units are affordable housing tenants and 5 of them are on a master lease with this company who lets the homeless community use the units.

Lots of them try, but you can just tell them to pound sand.
