The area figures come from quarterly data for the last 12 months (Q2/25, Q3/25, Q4/25, Q1/26*), while the city figure above comes from annual statistics for 2025. The periods differ, so the figures do not add up. Areas with fewer than 6 sales in 12 months are missing from the list, but their sales are included in the city figure.

The average price is in euros per property from completed sales over the last 3 years, and the number of sales is a count. The area figures do not add up to a citywide average: the register does not publish cells with fewer than three sales, so some of the municipality's sales fall outside this list. Sales of detached houses on leased plots are not property sales and are not in the register at all.

Home price estimate: Sastamala

The figures above are area averages. The value of an individual apartment differs from them depending on its condition, its floor, what has been renovated in the housing company and the maintenance charge. AsuntoAnalyysi calculates an estimate from these using completed sales in your own postcode area.

Two factors weigh differently on the estimate at different price levels, and they work in opposite directions. A renovation costs the same in a cheap and an expensive area, but in a cheaper area a smaller sum is deducted from the estimate, because the area's average price already includes its typical repair backlog. The maintenance charge, on the other hand, is a fixed amount per m², so its share of the apartment's value grows as the area gets cheaper. At the €1,314/m² level of Sastamala, that means this:

FactorIn a 70 m² apartmentShare
Upcoming pipe renovation −€30,700 −33.3%
Maintenance charge €1/m²/mo above the area level −€5,300 −5.7%
The contract price of a pipe renovation, as the shareholder's portion, is about €1,000 per m² of apartment, or about €70,000 for a 70 m² apartment. When the area's price per m² is below the reference level of €3,000/m², the full contract price is not deducted from the estimate: a full deduction would count the repair backlog twice. The deduction is then the same share of value in every area below the reference level, but smaller in euros the cheaper the area is. Percentage-based factors (condition, energy class, floor) have the same effect regardless of price level. 70 m² is an example size here, not calculated from the data.
