How CAM Reconciliation Works

Tenants pay estimated CAM monthly based on the annual budget
At year-end, actual expenses are tallied and compared to estimates
If actuals exceed estimates, tenants owe a true-up payment
If actuals are lower, tenants receive a credit or refund

Just a heads up, in some markets CAM reconciliation can confuse tenants and burden operators—some prefer modified gross or gross leases to simplify billing.
