"The Irish property market will likely continue to stabilise for the next two years, in our view," the analysts said.
"The heavy slump in the Irish housing market appears to have bottomed out," the report states.
House prices rose in the last three months of last year. This was the first time there was rise in a three-month period compared with the previous quarter for almost two years, S&P said.
But recovery is a long way off because of limited mortgage lending by banks and a glut of unoccupied properties.
The introduction of the property tax this year may also act as a drag on the market, according to the report.

Only Britain and Germany are expected to see house prices rise this year, according to S&P.
