You could determine FMV for property management and compensate the party providing it even if it's one of you. 

My desire would be to tender a contract to purchase the property, pay off their loan while ensuring the owner receives fair compensation and I receive the house.

For the record, I receive ZERO compensation for making this referral!

We would bring in compensation to make it worth it too him and he seems to be open to the idea as long as we can figure out a way to do it without too much penalty on his side.

Thereby the seller doesn’t end up taking the property off the market for t0 days, and gets “compensated” $100 when the borrower exercises his option to withdraw from the deal. 

But, they will owe you that money whether regardless if whether they buy a property or not.It is when you tie your compensation to the actual closing of a real estate transaction, whether flat fee or percentage based, that would create trouble for you regarding licensure.

The walkthrough can play a critical role in determining compensation.

But we'd also like to be compensated for this cost especially since we are offering our residents a service. 

If the seller’s offered compensation is equal to or greater than 2.5%, I will retain up to 3% of the sale price as my commission.

Do I provide my own document for what we're asking for that includes loss of use (and compensation for my time)?
