The AED 35,000–55,000 JVC range and the AED 25,000–40,000 International City range look close on paper, but the gap in what you get for it is not just about the building — it is about how much of the saving survives contact with a daily commute. Discovery Gardens sits in between on price partly because Ibn Battuta Metro access is priced into the rent, not because the flats themselves are noticeably better.
Work out the real cost of International City's distance from a metro station before signing — taxi or fuel costs on a daily commute add up over a year in a way that erodes the headline saving, sometimes past the point where JVC would have worked out cheaper overall. If you do not need to commute daily, that calculation changes considerably and the cheapest option stays cheapest.
