Match the version and category
Check the project, issuer, phase, unit size, plan version, effective date and valid-until date. Make sure the schedule refers to the option you are considering.
Look at dates and totals
A fixed calendar date differs from a payment due after a notice or milestone. Ask how previously paid amounts, membership fees and adjustments relate to the total.
Clarify extra charges and discounts
Ask which charges are included or additional, when a discount begins and ends, its calculation basis, and whether it can be combined with another offer. Keep the issuer’s current document.
