Based on my initial research, I have decided to look into multifamily properties which I will hold in the long-term and rent out (otherwise leverage the property for the next deal).

If you're considering a mentor I would try to not think about how much money they charge, do pros and cons of a few that you like (excluding $ amount), pick your favorite based on the value they bring, then factor in the money.

FYI  roof.io charges $2/tenant  (www dot roof. dot io/pricing/)

The owner would literally charge me a super low interest rate and hold the note probably no longer than a year.

That was their initial approach - to petition the seller for a return of their EMD, but I felt that wasn’t fair as the seller didn’t do anything wrong - the bank and their realtor were at fault.I may not have mentioned this but the HOA provided all needed documentation of renter/owner ratio before the offer was submitted - bank had that paperwork from day 1 but didn’t decline based on it until the day closing was scheduled to occur.

What I’m looking for is an example of an “Exclusive Right to Lease” agreement for a commercial building and some guidance on how to charge (not fee specific) and maybe some tips on marketing such an animal.

In exchange they will charge you a higher interest rate.Hopefully one of those 3 can work for you. 

The commission you charge yourself is one of your costs as selling as a consumer.

They do mandatory yearly inspections of all rentals, and charge yearly fees for each unit.

With that said, yes, they're taking advantage of you and you need to take charge.
