I understand that you’ve had a bad experience with AHP. Perhaps they are understaffed, or too big. I will send my tenant a 3-4 question survey.
AHP does provide a recommendation on rental rates at the end of the lease … and since 2000 they have always (OK, 3 times, not much of a sample size) recommended for me to keep the same rate.
If the owner tells them to raise the rent AHP will do it. The renter will likely leave and the owner will find out what the current market rate is to get a new tenant.
As a side not, I don’t think the term “lowly renter” really applies these days. You are living in a place for about 4% of the current “value” annually. That’s like getting a mortgage of < 3%. Renters are living like kings now. How about "kingly renters" or "queenly renters" ?
