Developer payment plan or bank mortgage - which is better?

Developer payment plans (e.g. 80/20 or post-handover) are usually interest-free, need less cash upfront and are tied to construction milestones held in DLD escrow — ideal during the build. Bank mortgages charge interest but spread cost over up to 25 years with smaller monthly payments, suiting ready homes. Many buyers use the developer plan first, then take a mortgage at handover.
