100 dollars per door

[Luis Saez]

I've listened to most of the podcasts. And I've noticed that as a potential buy and hold investor, the podcasts indicate that you want to have at minimum $100 cash flowing per door. Now i live in CT and this number doesn't make sense. I have friends, who without trying have 2 one-family homes cash flowing enough to cover the entire cost of a 2012 bmw. The cash flow covers the car payments, insurance, gas and maintenance. And he lives in new haven, CT, and that city hikes your auto insurance premiums substantially. He didn't give me a number, but I'm guessing he's cash flowing like $800/month at least. Is he full of it, or is CT just a different beast? Because i do note that most places in the US have homes selling for 100k according to podcasts, but most homes in CT are least 1.5-3 times that number easily. What am i missing
