Help basing lease off price per acre vs price per sqft
I have someone asking about basing the lease off of the acreage over the sqft. Property is listed at $3m, 15000sqft and would lease at $15/sqft. It’s also 3.79 acres and could possibly go for about $7500 an acre. 

The person is saying that based on those figures there would be that if you base the lease on a per acre basis there would be $45k of incremental NOI. 

I have no idea how he came up with $45k, any thoughts?
