Check the statement period and opening balance
Confirm which dates the statement covers. If it shows an opening balance, carry that figure into your review; it may explain why this month's payout differs from this month's rent. Not every statement uses the same fields, so follow the one you have.
Find money received, not only rent charged
Rent billed and rent collected are not always the same figure. Look for the amount actually received during the period and for any other income listed. If an expected payment is missing, ask your manager what status the statement reflects.
Review charges, reserves and transfers
Check each fee, repair charge, reserve movement or transfer against its label and your agreement. A reserve may be money held rather than money spent. Ask what an unfamiliar entry represents before treating it as an expense or a payment to you.
Reconcile the amount paid to you
Follow the statement's own calculation from opening funds and money received through charges, funds held and the final disbursement. If the result does not match the amount you received, ask which item or timing explains the difference. Keep the statement and agreement together for that conversation.
Ask about any owner-statement entry you cannot match
Name the period and the exact line item when you contact your manager. Ask what work or transaction it represents, when it occurred and where it appears in the agreement or property records. That is more useful than guessing from a label alone.
