This weeks property advertisement takes us to West Pennant Hills, where you could buy a house and land package for as 7700 pounds ($15 400) in Lisle Circuit in 1967. That was the equivalent of $179 000 in today's money according to the RBA Inflation Calculator.

I decided to see if I could find the house featured in the advertisement and it appears that it is still standing according to Google Earth. It is located at 4 Lisle Circuit. The front fence is gone but a few trees and shrubs have grown in its place.
