The inventory is very low for multi-family in my market but rents are good and in high demand with a quality, stable job base here in our rural community.I have an opportunity to purchase a multi-family property from a gentleman who wants out of the business.  

Based on the location I would guess it has been rented before.

The Southbay to be specific based out of Gardena, CA. 

I don't have any experience with them.however since they are CA based and did not post a CA BRE license number or CFL or NMLS I suspect they do not lend on 1 to 4 units as those require those above licenses if your in CA.Also I am always a little curious about those that say they lend from 20k to 20 million LOL.. no one can make a dime on a 20k loan... so thats curious.Lastly and this is just a personal pet peeve I just don't care for companies that don't list their principals and a small bio on their web page so you can look into the owners on google and make sure they are upstanding citizens.. again maybe its a marketing thing and maybe I am all wet but thats my preference I want to see who the principals are... they should be proud to put themselves up there ( again my pet peeve LOL)Just don't sent any up front money..

On the other hand, I also wouldn't advise going for an A property based on the possibility of appreciation.

When you finance it out, most banks will base the loan on the lower of the strike price or appraised value.  

Get a quote based, at the very least, on each trade.

Just want you to know that my company is based in IL and Silicon Valley. 

When we are underwriting an acquisition, I might glance at the market CAP just as a stick-in-the-ground reference, but will base our offer on the performance of the business and the quality of the revenue streams.  

A local bank will qualify you based on debt to income ratio.
