Question on Commercial Lease

[Frank Painter]

Hope this is the right place for this.

I'm venturing into a retail business and after some negotiation have been given the following numbers for space 

3,500 SQFT of commercial retail space in a small strip mall that include a supermarket and walgreens, and salvation army donation store.

$18 per sqft with $6 CAMS per sqft

3 year lease with 3% yearly increase

Is this reasonable?
