Estate agent Sherry Fitzgerald has said second-hand house prices rose by just 0.1% during the final three months of 2006.
Strong growth in the first nine months, however, brought total growth for the year to just over 18%.
Second-hand house prices in Dublin actually fell by 0.7% in the final quarter, though the rate of increase for the year was 22.2%.
Sherry Fitzgerald economist Marian Finnegan described 2006 as 'a year of two halves', with spectacular growth in the first six months moderating in the second half. She expects a slowing towards single digit percentage growth in 2007.
