Duplex House Hack Cash Flow Question

[Dave McCulley]

I am looking to get out of my current SFH and into a duplex to house hack. I know cash flow is very important and getting the best deal is the most important thing.

If I break even of have to pay a little in mortgage by renting out one side and house hacking the other all while building equity in it, is this not a good idea since it's not cash flowing yet?  

I want to get into duplex owning, but as far as living in one, I don't want to be in a class C neighborhood and would have to pay more.  

Anyone have any expertise in this area?
