We were quiet, predictable, don't-rock-the-boat tenants, and the rando owner mentioned that they valued that enough that raising rents wasn't worth the potential risk of new tenants who might cause them more hassle.
My sister was a sex worker for a while when she was younger, and trying to do things like rent was difficult because her income fluctuated a lot (always enough to cover rent, but she'd save during good months for poor ones) and she was technically self-employed. Or if you're on any form of disability, or if you had a medical issue that trashed your credit, etc. People getting out of prison, and so on.
If you stray from the happy path, woe unto you when dealing with large companies.
We ended up finding a friend-of-a-friend who had a bedroom to rent, but she will not (at least in the near-term) be able to rent an apartment.
At the time, I was legally limited in the amount of money I could make because I was relying on Medicaid and subject to income limits. I have MS and not having access to MS drugs is very, very bad and risks permanent consequences. The drugs also are ridiculously expensive (I think my monthly medication is about $30k/dose).
I had money, it was just all earned under the table on the grey market. Not a situation a corporate landlord is going to deal with, but I never missed a rent payment and I'm a very good tenant (clean, report issues promptly, read and adhere to the lease, etc).
I'm no longer subject to those income limits and I have a W2 job now and could qualify for an apartment based on that, but for a long time that wasn't true. On the margins, you end up having to look for the small time landlords, employers, etc. because if you're decent and you can talk to them, you can get a shot.
If you have that level of acumen, you likely don't have to be a sex worker.
