Though I have no interest in the transactional job of real estate, these sort of things (doing management, easy access to properties on the market) make getting my license more and more attractive on a practical level.

If lender's experience is a rather integral part of the transaction and it's on-going operation it would make sense to have a premium over just a passive capital rate. 

Whichever of us provides the management side of the transaction has 51% ownership so decisions can be made.

Sometimes you need to hold their hand throughout the transaction as most sellers are clueless about the process. 

I have done, been involved in, and/or brokered thousands of transactions over those 42 years. 

In fact Fanniemae has up to 80% LTV product.

The lawyer used during the transaction should have it or the mortgage company.

No, this would be considered "Prohibited Transaction" by the IRS.

When this transaction is done, I will be receiving $20,000 profit thereabouts (not considering closing costs, agent costs, etc).

Regardless, if you're dealing with cross-border transactions you need to make sure you have the right structure, banking/lender/property manager relationships, CPA and lawyer in place.
