Mortgage Interest Costs Double in Five Years as Irish House Prices and Rents Continue to Rise

Dublin: The monthly interest cost of a mortgage in Ireland has doubled over the past five years, according to the Central Statistics Office (CSO), highlighting the growing financial pressure on homeowners and prospective buyers.

The increase has been driven by a combination of rising property prices and higher mortgage interest rates. Meanwhile, rents have climbed by 36 per cent over the same period, adding to the difficulties faced by households struggling to find affordable accommodation.

The CSO report shows that residential property prices in Ireland increased by 41 per cent in the five years to August 2026. Rents also rose by 36 per cent during that period, reaching their highest levels since records began in 1996.

Rental costs have increased every month since July 2021, according to the report. The continued rise has placed considerable pressure on tenants, particularly those who are unable to enter the property market.

The cost of maintaining and repairing homes has also increased significantly. CSO figures show that repair and maintenance costs rose by 19.3 per cent over five years, reflecting higher prices for the goods and services required to carry out household repairs.

Mortgage interest costs reach highest level since 2008

Mortgage interest costs reached their highest level since October 2008 in October 2026, according to the CSO. The increase reflects the combined impact of higher borrowing rates and rising property values.

Figures from the Central Bank of Ireland show that the average interest rate on new mortgage loans stood at 3.52 per cent in September 2026, compared with 2.72 per cent in September 2021.
