Sydney investors are increasingly buying properties in Brisbane solely on photographs and skipping inspections.

Agents in Brisbane suburbs considered “unfavourable” said investors have boosted house prices in what have historically been more affordable suburbs.

These include Inala, Woodridge, Eagleby, Forest Lake and Slacks Creek, all 25 minutes south of the city. All featured in Queensland Police Service’s top suburbs for unlawful entry with intent in 2014-15.

White Knights Realty Logan agent Kym Whalan said blind-buying Sydney investors had flooded into​ the Logan market.

“Out of every 10 sales, five will be investors, and two will not have viewed the home, and that is a modest estimate,” he said.

“Often it seems as the investors have no idea about the area’s reputation. Or maybe they are overlooking them because of the good house prices.”

He said a wave of Sydney investors had targeted Woodridge, a suburb of Logan , which boosted prices.

“I think locals might be wondering to themselves why it is becoming more expensive all of a sudden.”

Professionals Beenleigh office manager Lesley Waters said it was more common for Sydney investors to buy in Eagleby without viewing the homes first.

“We are seeing about 70 per cent of Sydney investors buying without seeing the homes,” she said, but added that she believed investors were well informed.

“I always make sure to explain the area to buyers, and make sure they are not under the wrong impression,” she said.

“But investors are drawn to being close to the highway, the location between Brisbane and the Gold Coast and also good rental returns.”

But buying properties without seeing them prior have raised some issues between agents and investors.

Coulson Real Estate Inala agent Daphne Orley had to drop the price of one of her homes after an investor complained about discrepancies between the photos and the property after buying.

“I dropped $7500 off of a house price that was bought from an investor who hadn’t seen the home because of cracks that did not show up clearly in photos,” she said.

Her past two sales in neighbouring southside suburb Acacia Ridge sold without inspection.

LJ Hooker Logan City manager Tony Hall said that although investors bought blind, they were usually followed by an inspection from someone close to them.

“Sometimes you will have the buyers get someone they know in the area, like family or friends to view the property for them, and they will go off of that advice,” Mr Hall said.

“I have had homes crash after a follow up inspection, just as I have had homes go through after a follow up inspection.”

Other agents have enforced visual inspections.

New Image Real Estate Marsden agent Christine Carroll has included a clause in her listings.

“I do not sell without a visual inspection. In my view it is the ethical thing to do, because it puts the ball into the buyers court, and at the end of the day I want them to know what they are buying and it is in the best interests of the buyers,” Ms Carroll said.
