Registered transactions from the DLD in Dubai and ADREC in Abu Dhabi, community by community. These are transfer prices, what buyers really paid, not the asking prices portals show. Every sale is read against its own like-for-like median: same area, same property type, same bedroom count.
The registry publishes no project name against a sale, so like-for-like here means the same registration area, the same property type and the same number of bedrooms. Selling and want your own number first? The instant valuation uses exactly this data. Methodology.
