It seems doable, until all the shit you described happens. After which the 15~20% cut (the kinda rates these companies want over here) doesn't seem so bad anymore. Especially compared to the loss. A friend of my aunt had a tenant with some mental disorder that wasn't able to find a job again after covid, yes that means 4 years of not paying, the landlady didn't have the balls to kick the tenant out, and now the court proceedings might take another year. So yea, there is a risk, but only if you ignorantly chose to do it your self without knowing what you're going into.
