Raising money is all about marketing and sales (not real estate specific) so either hire marketing agency and read sales books, or hop on some LinkedIn courses on marketing and sales.Not sure the legal structure to use: talk to accountants and attorneys.Need deal flow: talk to brokers and go to a lot of networking events.Lending terms: start calling banks and loan brokers.From there, it is all risk mitigation. 

If you are a legal property manager in your state the owner should have the unfettered ability to allow you to act as his/her agent to enforce the lease, whatever provisions they may contain plus whatever your state laws allow.

It is right on the fringe of being legal/illegal, and lawmakers have been talking about how to regulate it for years because it can be a dangerous process that leaves end Buyers feeling like they weren't represented.....especially when they see the closing statement and find out how much the wholesaler made just by getting to the Seller first. 

Consider balancing liability protection with administrative costs, and consult with a CPA to align your structure with your financial and legal goals.This post does not create a CPA-Client relationship.
