Building a multi-use building

[Jay S.]

Hi,

I own several SFR rentals as well as a 15-unit apartment building. Along with my architect partner, I'm now looking at building a multi-use, both retail and residential building on a lot we possess in urban SoCal. Is there a book or other resources you can recommend that discusses construction loans, bridge loans, and the final stabilized commercial loan (the latter I am well versed in). The lot is on the order of 12,000 sqft.

Also, does it make any sense to pursue "Affordable Housing Finance"? 

i.e.

http://www.housingfinance.com/

Are there government incentives over the conventional construction process?

Thx,

J
