Friend tried renting some property in FL. It was a miserable experience with tenants who constantly trashed the places, having to hound them for rent while she had to pay the mortgage on time, etc. She eventually sold it and said "Never again."
Not counting corporate landlords, cause that's a whole other can of worms, 50% of landlords are below average landlords, and 50% of tenants are below average tenants. So 75% of leases have one below average party, antidotaly anyway. (Obviously this isn't real math)
We rented a house after we moved out of it. It was a nightmare, and we'll never do it again. They stopped paying rent for months, then wouldn't move out. If they had a legitimate hardship we would have worked something out, but they were just shit people. We ended up having to take them to court to get them out. If they had just left without it going that far, we wouldn't have even pursued the back rent. The house was deep down nasty when we got in after they left.
There are definitely predatory landlords, and there do need to be protections in place. However just because someone charges money to live in a property they own, they aren't necessary brutal capitalists out to fuck over anyone they can
