Price per acre or sq. foot of land for ~3 acre parcel for chain

[Ed Long]

I know a lot of this is 'it depends'.    

Looking at 5,650 - 11,300 SF Industiral/Flex on ± 3 AC
• Outparcel to Home Depot Shopping Center (across the street), +-400ft road frontage facing HD, backs up to major interstate.

Area is good, land is level, zoned properly and I've seen a lot of BKs across the home depots in my area (for some reason) and was thinking this is a similar setup.  

After searching, I could not find a good reference to determine the % of land cost for a chain like BK to determine if this is a feasible Invesment.
