Need title & loan servicing recommendations for seller financing

[Kevin Wong]

I have a potential multifamily deal in Los Angeles with the seller willing to finance. High level, I understand how the seller financing works, but dont know the granular stuff of how to get it into an agreement and serviced. Are there specific title companies locally more familiar with seller financing? And who does the loan servicing and collect the payments?  Anyone who has done this in Los Angeles I'd appreciate any tips.
