Finding a portfolio lender

I recently closed on my 10th property and, according to Fannie Mae, I'm cut off! I have been looking into other options such as blanket loans and portfolio lenders, so that I can continue investing. From what I understand, a portfolio lender is the way to go. However, I'm having trouble finding one in my area... that will do loans out of state. I live in California but my rentals are all in other states (since California is ridiculously over-priced). Any tips on what to do or how to find a lender that will accommodate me? Am I searching for something that doesn't exist?? Thanks.
