If you're planning on using an management company, plan on breaking even, at best. You'll have a tenant that doesn't give a shit about your property and a management company that doesn't care either, and you can expect any meagre profit you might get back from the management company to be soaked up in the repairs and refinishing that'll be necessary between tenants.
If you want to do this, maximize your profit by purchasing a fixer-upper for well below market value, put in the work yourself, and then forget the management company - interview the potential renters yourself. Price the rental high to weed out the dirtbags, and then be very very picky who you end up renting to. It'll save you money in the long run if you wait to find the responsible renter. It's effort on your part, but money ain't free. Real estate is not something you can just throw money at and walk away and wait for it to grow. Successful real estate investing is actually one of the hardest ways to make your money make money, although the returns can be good if you get good at it.
Oh, and get a lawyer who specializes in representing rental owners to advise you. Very important.
