Price against the market

Asking price vs actual transactions

Developer asks
10 700zł/m²
Actually paid (new-build)
9801zł/m²
Difference
+9,0%

Median of 146 new-build transactions across 8 buildings within 2 km over the last 12 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.

11 developments within 1,5 km, median 9680 zł/m². This investment: +10,5% vs neighbours.
