Listed real estate agency McGrath says it expects a full year core earnings loss of $6 million to $6.5 million due to continual headwinds across the nation's housing market.

The ASX-listed realtor said on Friday market conditions for the 2019 financial year had been challenging with transaction volumes and property values in Sydney, Brisbane and Melbourne further subdued in the 12 months to May.

"While we have seen a general improvement in interest and enthusiasm in the market, we are yet to see this translate to an increase in listings," chief executive Geoff Lucas said in a statement.

The increased loss estimate follows the group's March update where Mr Lucas revealed an underlying EBITDA loss of $4.5 million for the eight months to February, 28 2019, with the company reporting subdued property market expectations, evidenced by generally lower listing volumes and average sale prices.
