Expensive Multi-Fam w/ 10% Down

[Blake Alexander]

Hey BP!

I have a client who is looking to buy a 4 unit multi-family with 10% down. The issue is prices in my area generally require 40%+ in order to cash-flow. There are also rent controlled tenants in many of these buildings who are nearly impossible to get out, many of whom are paying 1/2 market rent. 

Is there a better way to go about this search? Can I reverse engineer this in a way to find only the buildings that will cash flow at 10% down?

Any help would be appreciated!
