Calculating sqft for RV/Boat Storage

[Trent Kloter]

Hello.

I'm running an analysis on a RV and Boat deal. The property is RV and Boat with some storage pods. 

When it comes to calculating the price per sqft, what sqft # would you be using? the sqft of all the spaces + storage pods? or the sqft of the entire parcel? (# of acres)?

I'm used to calculating the net rentable sqft of storage properties and I always exclude outside parking in NRSF.
