## Prices per m² by apartment type

Average prices per m², weighted by number of sales, from completed apartment sales in postcode area 15170 over the last 12 months (Q2/25, Q3/25, Q4/25, Q1/26*). The example price shows what a typically sized apartment would cost at the area's average price per m².

| Type | €/m² | Sales | Change | Example |
| --- | --- | --- | --- | --- |
| 2 rooms | 873 | 23 | +4.1% | €48,000 55 m² |
| 3+ rooms | 909 | 13 | – | €73,000 80 m² |

The missing types (studios, terraced houses) had fewer than 6 sales in 12 months in this area, so no reliable average price is shown.

## Price trend Q2/23–Q1/26*

Price per m² by quarter. The annual change comes from a sales-weighted regression over the whole series, not from the difference between the first and last quarter, so noise in a single quarter does not swing the figure. A quarter marked with an asterisk is preliminary. For 3+ rooms, Statistics Finland publishes only isolated quarters for this area, so they are not charted and no annual change is calculated.

## Sales volume trend in the area

How many apartment sales took place in postcode area 15170 per quarter, stacked by apartment type: 197 sales in total over Q2/23–Q1/26*. The number of sales reflects turnover in the area: in an active area price estimates are more reliable and time on market shorter, while fading volumes signal cautious buyers.

The count is published even for quarters with no published average price, so the chart also shows apartment types with few sales. The last quarter (Q1/26*) is preliminary, hence lighter.

## Detached house sale prices 2017–2026

Postcode area 15170 had **9** detached house sales in 2024–2026, at an average sale price of **€192,278**. Prices have been stable over the whole period, despite differences between individual years. The figure is the **total property price**, plot and building together, and is not adjusted for house size. [How the detached house figures are calculated (in Finnish) →](https://www.asuntoanalyysi.fi/tietolahde-ja-menetelma#omakotitalo)

| Year | Average price | Sales |
| --- | --- | --- |
| 2026* | 189,167 | 3 |
| 2025 | 193,833 | 6 |
| 2023 | 253,000 | 5 |
| 2022 | 287,667 | 3 |
| 2021 | 263,833 | 12 |
| 2020 | 167,667 | 3 |
| 2018 | 172,333 | 3 |

The average price is in euros per property and the number of sales is a count. The register has no floor area for the building, so **a price per m² cannot be calculated** and the figures are not standardised for house size: large and small houses share the same average. Sales of detached houses on leased plots are not property sales, so they are missing from the register entirely. Year 2026* is still in progress and will be completed later, so it is left out of the annual change.

## Rent level and rental yield

Average rents for non-subsidised rental homes are at the level of **Lahti** (2026Q3): Statistics Finland does not publish rents by postcode. The rental yield uses this area's realised price per m² and the city's rent level, so it is indicative.

| Type | Average rent | Example | Gross | Net |
| --- | --- | --- | --- | --- |
| 2 rooms | 12.89 | €710/mo 55 m² | 17.7% | 11.0% |
| 3+ rooms | 11.52 | €920/mo 80 m² | 15.2% | 8.8% |

Average rent is in euros per m² per month. Gross yield = annual rent / debt-free price. The last column subtracts a typical maintenance charge (€4.88/m²/mo, national level). It does not account for empty months, renovations, housing company loans or taxes.
