According to the Central Bureau of Statistics, the National Statistics Office (CSO) has reported a decline of 0.5 per cent in July.
This is the first annual decline since May 2013, economists said.
Statistics show that prices rose marginally by 0.3 per cent in July.
However, there was a significant decline in the number of transactions during the month.
Prices are now stable despite the devastating effects of the epidemic on the economy.
Prices were higher in April and May but flat in June.
Experts say the price index is based on stamp duty filings, so the impact of the corona virus on the market has taken some time and it will take some time for solicitors to send it to revenue.
