The amount by which house prices have increased over the past decade, according to new lobby group Australians for Affordable Housing. Incomes increased by just 57% during the same period.

The sale price of Ballarat grazing property Trawalla. The sale has buoyed an otherwise depressed rural market.

The price hopes for rugby league player Darren Lockyer's Brisbane house. Lockyer put the property up for auction in early August but has been unable to find a buyer.

The reported price of the Robina Woods and Colonial golf courses, which mining boss Clive Palmer bought this week. The golf courses went on the market in July after Playmore Golf went into receivership.

The annual rent at the new Gant store in Queen Street, Woollahra. The menswear store is moving to premises vacated by Robert Burton, who is moving across the street.

The indicative gross rental yield in mining boomtown Port Hedlund. Tim Lawless, head of research for RP Data, says mining towns can be attractive prospects but warns that they are unstable investments.

The price hopes of a property listed by the Leal family in Paddington. If the property sells for that price it would smash the previous Paddington record of $7.75 million.
