Median of 22 new-build transactions across 9 buildings within 2 km over the last 24 months. We compare apartments of similar size. Source - notarial deeds, RCN registry.

Notarial deeds reach the registry with a delay of several months, so part of the gap is price growth over that time. Above transaction prices does not always mean overpriced: construction stage, standard and views matter.

9 developments within 1,5 km, median 9500 zł/m². This investment: 0,0% vs neighbours.
