I wanted to know if anyone has had any experience doing lease options in California. Wanted to know the best practices for: 

1. Obtaining loan/mortgage information from the lender of the property, including any clauses that may trigger due-on-sale. 

2. Notifying this Lender that they will be receiving payments from a different entity (my company) and to send future statements and notifications to this entity instead of the current borrower (seller). 

Basically, I want to know how to best ensure that the mortgage (and insurance) payments are made in timely manner and that the seller doesn't use these checks for some other purpose.
