One issue I keep running into is their refinance is based off of total cost(acquisition and renovation) as compared to Market appraisal.   

@Michael DohertyInstead of trying to figure out the perfect equity split to pay you for finding and running the deal, charge an annual PM fee and a one time acquisition fee. 

@Laurie ClarkstonThere is no quick calculator that will tell you how your tax will change upon acquisition of a rental property.There are too many variables from investor to investor1) Investors can be in different federal tax brackets2) Investors can live in states with different tax rates3) EtcThere is possibly a quick way that you can see an estimate of what the change will beYou can research what marginal tax bracket you are in. 

If the interest has been held for seven year on the date of inclusion the deferred gain is discounted by 15%.If the interest in the QO Fund in held for ten years on the date of actual disposition, then any additional post-acquisition gain due to appreciation in the value of the QO Fund interest can be eliminated under an election to treat basis equal to fair market value.To benefit from the maximum discount (15%), the investment must be made by 12/31/2019.

Update: In a few short months since acquisition, 6, we have driven our rents from a per door average $660 to $810.

Typically lease terms are for 49 or 99 years.Also, generally you cannot finance land acquisitions using conventional financing, so you can't leverage the purchase unless you really know what you are doing.

Pertaining to Kris Krohn: (As of 2/25/2020)To partner w KK and his team, its $10k to $25K to join his partnership program (he has 3 levels) then $2K to $5K Acquisition Fee Plus the 50% equity split per property.

In fact Loren guided me through my first court auction acquisition.

Should I expect the acquisition price per SF to decline as the building's size increases, e.g. 100 unit property vs a 10 unit property?

The answer is probably to line up financing, and move forward with acquisition but you should really form a plan about the types of investor you want to be and what you hope to accomplish.
