Sterling Bank is lending on case by case in Oakland,Ca. You might want to find out which bank (Sterling or NCB) is financing the other units in the building in which you are interested this will indicate you which one of the 2 banks in the US might finance your loan. Or hard money lending can be an other option. Good Luck
Jenny Shore has done them for a long time. She is with Alternative Mortgage Services in Emeryville: 866-861-5708. I have not used her or had clients with the need, but colleagues I know and respect have used her for their TIC clients, and been very happy. Good luck!
