The only people who ask this question are people who haven’t been landlords. Every single one of my friends who has, can commiserate with me as a former landlord.
Maybe buy a vacation home to rent, or an apartment complex. And of course being a part- or full-time landlord is a perfectly reasonable job.
But if you think that being a landlord just means having someone else pay your mortgage, I guarantee you will think differently after a year with even exemplary tenants. And most tenants are far from exemplary.
