I had to chuckle today when I reviewed an email from a commercial PM. (not just one PM but a PM, an administrator and an accounts department). One side was disputing the rent review mechanism (ratchet between CPI and market). Kept arguing it was the Lessor of Market or CPI. Doh! (This one was switched on). The other didn't know what a ratchet was or how to interpret it. They fessed up that they were new to commercial property. When pointed out the error of their ways, they calculated the CPI review - still had no idea so sought the assistance of the accounts department - wrong base dates and no idea how to adjust. We had to explain ie put all the numbers down in order of calculation so they could understand it. I printed the email as backup for a legal instruction - there were 8 pages!!! - I didn't see the whole story until I printed it, all I cared about was matching the result to the agreement and thought it would be simple (result was on the front page). I've got a sore head. Moral of the story - vet your PM for your CIPs.
