It's actually a legal duplex, non conforming as it's in a SF zone.

Keep in mind that if you do a conforming owner occupied type loan you will be required to live there for a period of time before renting it out. 

@Kyle Weckman Some other options are through either a conforming loan or HML.

A VA loan is 100% financing only up to the conforming loan limit of $424,100.

This isn't to say that because of this they are all "legal & conforming" however, this pair of buildings (sold as a bundle) are.In regards to the condo part of this, I didn't know much about it until the last day or two after doing some deep diving into the statutes.
