The figure comes from the Principality's House Price Index.
The average house price in Wales has reached a new high of £174,319 during the first quarter of the year.
The figures come from the Principality's first House Price Index.
The report finds the average house price in Swansea stands at £169,587.
In Neath Port Talbot people can expect to pay £122,948 and £154,893 for properties in Carmarthenshire.
Tom Denman, Interim Finance Director at Principality Building Society, said: "While the average house price in Wales has steadily climbed to reach a new high, there are signs that the market is cooling slightly.
"While higher employment, consumer confidence and low interest rates have helped to keep the market demand steady, a rise in the cost of living could result in house prices growing at a more modest rate during the rest of the year."
