Real Estate Institute of Tasmania president Adrian Kelly said concern over job losses meant people were reticent to buy.

He said job losses in some regions had meant families needed to relocate, hoping to both find work and sell their home.

Aqua Real Estate director Daron Gumley said property listings in George Town had risen along with concerns over continued operations at Rio Tinto's aluminium smelter and BHP Billiton's Temco magnesium plant at Bell Bay.

``Take into consideration BHP and Rio Tinto, the relocation of the major port movements from Bell Bay - this on top of rising costs for investors being land tax and also the rise in water and sewerage costs,'' Mr Gumley said.

He said there had been an increase in listings from investors wanting to offload stock that they believed had reached their capital growth potential.

``We have seen a drop in price over the last 12 months from the asking price of around 10 to 15 per cent.

``In saying that, the prices were pushed to an artificial ceiling buoyed on by pending projects here so, inevitably, they had to fall sometime.

``With the lack of demand on rental properties, this doesn't allow the rate of return expected by investors with what they saw as a place to invest with the pending pulp mill that had enticed them to look here.''

West Tamar Harcourts sales consultant Vaughan Rose said Beaconsfield property listings had risen but sales in the area had dropped since BCD Resources' decision to close the town's gold mine by June.

The decision will put 103 full-time employees, 16 casual staff and 32 contactors out of work.

Mr Rose pointed to Bell Bay industry uncertainty and the pulp mill for both investors and home owners selling up.

``And there are certainly people who purchased their property in 2008 and 2009 who won't get that same figure back now,'' Mr Rose said.

Property and commercial listings have also risen in Burnie with an agency principal reasoning it was because the region's economy was as dire as it was 15 years ago.

First National Burnie principal Deanne Lamprey said although listings had risen, surprisingly, Burnie's median price had remained stable.

``While our level of sales have reduced from two or three years ago Burnie, quite surprisingly, has been sitting around $225,000,'' Mrs Lamprey said.

She said properties from mainland investors were predominantly coming on the market though they were in no desperate need to sell.

Buyers were likewise in no desperate need to purchase, turned away by news of a worsening state economy, she said.

Mrs Lamprey said signs of economic woe in the region could be seen in closed shopfronts.

``We're seeing a lot of empty shops sitting there for sale at the moment, similar to what it was like when times were bad in the late 1990s,'' she said.
