Home Buyers Find Surprising Bargains in Helsinki Suburbs as Rents Outpace Mortgages

For the first time in over a decade, buyers in select Helsinki suburbs are discovering that their monthly mortgage repayments can be lower than the cost of renting a similar property. Data released this week by the Helsinki Region Environmental Services Authority (HSY) reveals that neighbourhoods such as Kontula and Kannelmäki are leading a shift that could reshape the city's residential market.

Surging Rents, Steady Prices

The timing of this reversal is critical. Helsinki rents have crept upward, fuelled by a succession of interest rate hikes between 2022 and 2025 that pinched both landlords and tenants, followed by a growing inflow of migrants to the capital region. The supply of new units from city-backed schemes like Heka’s recent blocks near Mellunmäki Metro Station has done little to dampen fierce demand. Across the board, average asking rents for a two-bedroom apartment in Vuosaari now stand at €1,470 per month, up 9% from last year according to property portal Oikotie.

In contrast, the average sale price for a similar flat in Kannelmäki has dropped to €237,000, down 5.5% compared to June 2025, largely due to nervous sellers listing en masse this spring. Factoring in the current average 3.3% interest rate on a 25-year mortgage, monthly repayments come in at roughly €1,150—a difference of over €300 versus the median rent for the same size apartment nearby. The numbers are even starker in parts of Kontula, where some mortgage holders pay up to €385 less each month than tenants in comparable blocks on Keinutie or Porttitie.

Where the Numbers Work

“You can now buy a 62 square meter two-bedroom on Kaustisenpolku in Kontula and end up with a monthly repayment around €1,040,” said a data analyst at Realia Group, the city’s largest property services provider, speaking on background. “That same unit fetches €1,400 if offered for rent—and that's assuming you beat the queue.”

The confluence of slow resale growth and runaway rents means buyers with moderate deposits—often aided by government-backed ASP savings accounts—are finally getting better value than renters in eastern and northern districts. HSY’s analysis shows that in Puistola and Malminkartano, the rent-versus-buy equation tipped in buyers’ favour as early as February 2026. Even outside the ring rail line, in settlements like Myllypuro, the difference has reached €160 per month for standard family flats near Metropolia University; ownership now appears a financially prudent option for many long-term residents.

Yet, for those looking further west in Espoo or downtown in Kamppi, renting remains the cheaper—and often only viable—pathway, with purchase prices and entry costs still tipping the balance away from buyers.

Should Renters Take the Leap?

For would-be homebuyers, timing may be crucial. This affordability gap is being watched closely by municipal housing officials, with city economists noting that if rents continue their ascent, suburban homeownership could see a surge in popularity. First-time buyers are being advised to look closely at HSY's online affordability map and to consult lenders about fixed-rate deals, especially if they’re considering districts along the Vantaankoski rail corridor or eastern branches of the metro.

Meanwhile, property agents report that viewings in Kontula and Kannelmäki have doubled since May, sometimes drawing crowds more typical of the city centre than outer ring suburbs. As the market adjusts, Helsinki’s housing affordability sees its sharpest mid-year shakeup since 2010, and for renters sitting on the fence, the cost of waiting just got steeper.
