Match the unit number, plan, stated area and measurement definition against official documents. Identify how balconies, parking and common areas are described and which elements have been included in the quoted price.
Read the payment schedule, charges, handover date, delay and termination provisions, and the seller’s transfer obligations. An area discrepancy or alleged breach needs assessment against the agreement and rules governing that transaction.
Do not overlook an arbitration clause: it can affect whether a court hears the dispute. Compare the forum, seat, language and likely costs without assuming that either litigation or arbitration is always preferable.
