Real Estate Rule of Thumb is a Myth

Real Estate Rule of Thumb is a Myth

There is a real estate rule of thumb that adding a set percentage to an advertised property list price will get you close to the selling price for a home. Ten percent used to be the magic number bandied around. This rule of thumb is false.

Real estate sellers are generally responsible for setting the property list price, sometimes with the aid of valuers and/or automated valuation models.

In Baulkham Hills, NSW the difference between the sold price and the list price for each auction ranged from 0.5% to 14.1% (March 2017). Whereas in Bulleen, VIC the difference ranged from 10.4% to 28.1% (March 2017).

The difference between the advertised list price and final selling price of a property varies widely.

Therefore do your own research using independent property price predictions.


Here are the top 10 most accurate suburbs for list prices:

NSW Suburb Sold Price vs List Price
1 Kingsgrove 4.4%
