How to rent out houses for profit?

I want to start buying houses and renting it out to others to make a profit. For example, I buy a house for 400k and I take a mortgage on it for 500$ a month for a certain number of years. So to profit, I get a tenant who will pay me 2k a month so I make a 1500$ profit a month, and eventually misusing the regular costs. Is this a good business to do as a side job? How does it work? Is it risky? I think the most risky part is finding a tenant that won t f**k me over!

Obviously I will have to have cold credit scores and own a house for my family meanwhile. Thanks!
