Help with structuring a commercial purchase deal!

[Mac Usher]

Hi BP Family, 

I am thinking through a potential opportunity for a deal and I would like your insight on different ways to approach it. I'll give you some specifics.

Property:
 Building is 8855 Square Feet
 3-5 Acres of land
 Ideal for a small manufacturing company.
 Will require heavy cleanup and code updates

Financing:
Owner is looking to sell in the former of a Lease Purchase or Direct Sale.
Owner may be in position to Owner Finance.

Purchasing:
I have an interested buy who would like to pay a large down payment and then make monthly payments to finish the purchase over the next 5-7 years.

Me:
I would like to own a portion of the property also for equity reasons but I don't have any cash.

Question:
What are some fair and creative ways to approach this?

Thanks BP!
