When a broker emails a new rent roll for [PROPERTY], ask me before doing anything. If I say yes, copy the latest model in [FOLDER], update unit rents, occupancy and expirations from the new rent roll, and tell me how NOI, IRR and cash-on-cash changed. Check the rent roll totals against the broker's PDF and list any mismatch. Never overwrite the original model.
Replace [BRACKETS] with your details. {{double braces}} are fields your automation tool fills in.
