That's frightening re squatters. Here the only obstacle is a sheriff has to serve them - no private. Once that's done court takes five minutes.It's not a complicated process. In most states.... I've heard some horror stories out west with clients that have dealt with sophisticated squatters that have basically stolen their property with never- ending evasion techniques.
That said, I'm slowly extracting myself from my rental portfolio. I'll take my equity that's built up nicely over the last 10-20 years and dump it into the stock market and my own personal consumption, rather than play this game any longer.
The trends politicaly are obvious and they aren't positive towards mom and pop landlords. The result will be large private equity firms taking over the rental real estate market. I'm sure they will care a lot about their tenants and the improving the local neighborhood. This will be the big win for dimwits like Cori Bush.
As to your other points you certainly no better than i. What i do know are tons of landlords including my family and every one are mom and pops and need the money
