Fast Funding for California Commercial Real Estate

Rubicon Mortgage Fund, LLC has funded private commercial loans since its inception in 2008, all over California.

We are a direct private lender that specializes in short-term bridge loans for commercial and residential acquisitions, refinancing and equity cash out for business purposes, new commercial construction loans (SF Bay Area only) and hard money for rehab fix & flip. We understand that occasionally loans do not fit into the standard model of traditional commercial lenders; therefore, we focus on funding non-conventional commercial loans.
