Financing for 100 SFHs in Chicago

[Dooreuhn Cee]

My goal is to move from 20 to 100 SFH, buy and hold, cash flow properties in Chicago. The portfolio will consist primarily of SFHs because I prefer the neighborhoods, tenants and stability of such in comparison to multi-units.

However, financing is much more difficult because I cannot carry 100 mortgages on personal credit (cap of 10) and options are limited for corporate and commercial loans on SFRs.  I have not been able to identify any local banks as of yet.  The only national company so far that fits this bill is B2R now Finance America who I am already working with (Ridge only makes personal loans).  

Does anyone have suggestions? I'd also like to hear about strategies for building large SFH portfolios.
