No (institutional) lender will finance 100% of your purchase price as a purchase, all lenders want "skin in the game".

I like this option better than a Wrap because for me its just easier to understand and navigate, especially if lender calls the loan.With all this being said...I am just looking for those that have direct experience with using Lease to own to get into Multifamily and Apartment building type projects.

Lenders usually determine whether properties are lendable based on the debt service coverage ratio. 

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

There's a post right above mine from a lender... there's always a lender offering $$$ even when people can't afford it. 

Find a couple of lenders who lend in the area you are looking at. 

If they are up for renewal and you elect to non renew them you must stop accepting funds from the occupants after the lease expires (accepting rent after the lease expires may make it appear you have a tenancy at will agreement). 

Quote from @Ryan Konen: You are correct that comping software like Privy, Propwire, and Propstream primarily rely on public records for their data, such as county assessor records, MLS feeds, and sometimes 3rd party aggregators.

Courtesy of Dodd Frank, its doubtful the self employed will ever be viewed by lenders as favorable as a w2 employee.

They can also be more forgiving on condos (warrantable versus non) at times.
