There's quite a bit of optimism in those numbers.
I bought a house in the Bay Area in the 90s and the mortgage was well over $3K (remember interest was over 7%) and an equal house back then was renting for $1300 (my rent at the time for a 3br house in south San Jose).
Try to run the numbers for any property you like. Remember to include taxes and insurance and maintenance. Just to break even is not easy and then you'll have to work for free on the maintenance. Or pay a rental management company, which is another 8-10% taken from the rent.
