The development lobby is keen to convince everyone that the affordability problem is caused by low supply of residential land - but few people believe them, based on the latest poll on hotspotting.com.au.

Given a range of options from which to nominate the major cause of low affordability, the most popular choice was the natural property cycle. Around 40% of respondents believe the problem is simply a product of the sharp increase in prices during the recent boom.

22% believe that high buying costs is the biggest problem. Only 17% feel that low supply of residential land is the root of the issue and 13% suggested taxes that add to the cost of new homes were the problem.

Just 8% blame rising interest rates.
