Field notes
The calculation method treats rent and NNN/CAM as monthly costs, applies annual increases, and counts the tenant’s net build-out cost in month one. The page also cautions that NNN estimates are reconciled against actual costs annually and advises asking for the prior two years of figures. It describes the results as comparison estimates, not legal, tax, or financial advice.
