Looking for MFH 1-4 units - with Positive Cashflow?

[Rocky Rock]

I'm looking for MFH (1-6 units)/duplexes rental property in any state/city (Class B or A). My budget is $300-500K, planning to put down 25% - What are my chances of finding any properties with a Positive Cash flow.

Do you've any suggestions in which sate or city - I should be looking. I live in California (north) but right now prices are v steep here, positive cash or breakeven is also tough.
