- HOA dues
- Rent
- Assessments
- Utilities in limited circumstances
- Other recurring property amounts
Is a Proration a Fee
No. It allocates an existing expense or income between the parties.

- Amount
- Closing date
- Whether paid in advance or arrears
- Contract
- Escrow method
- Local tax calendar
- Agreed possession terms
Frequently Asked Questions
Does the buyer always receive a credit?
No. The direction of the credit depends on who paid the bill and which period it covers.
Can prorations change?
Yes. A closing-date change or updated bill can alter the amount.
Are prorations always exact?
Some use estimates when final information is unavailable, subject to the contract and escrow instructions.
Ask escrow to explain which period each proration covers and why it appears as a debit or credit.
