Yes. It is official land registry volume from TKGM Parcel Query — actual title-deed transaction data, not scraped listings or estimates.
What does the map actually show?
It shows district property sales at parcel level: how many buy-sell transactions each parcel saw in the year you pick. Dense clusters mark the streets where the market is genuinely moving.
How do I use this in a real estate market analysis?
Transaction volume tells you where demand is real rather than advertised. Pair it with price data and you can tell a client whether an area is heating up or just expensive.
Can I look at previous years?
Yes, you can select the year and the analysis type, so regional trends over time become visible instead of a single snapshot.
