The following property was advertised at $1,300,000 on the first day of posting. http://www.realestate.com.au/property-house-nsw-wahroonga-120204997 The agent changed it to "Expressions of interest" in next few days. The property got sold for $1,490,000 at the end. An increase of $190,000 in just two weeks!! I went to inspect the property, while there were good potentials, but the "environmental" factors did not impress me at all. The good: 1. 650 metres to train station 2. corner block with sub-division potential (but house is right in the middle of the block) The bad: 1. next to rail way -> occasion noise (health concern) 2. 5 metres from main road -> constant noise, polluted air (health concern) 3. 20 metres from Pacific Motorway -> constant noise, polluted air (health concern) 4. 400 metres from the exhaust stacks of M2-M1 link tunnel -> concentrated polluted air (huge health concern) Obviously, money before health And of course, kudos to the agent as a seller agent. She just got $186,200 more for the seller (& $3800 for her company).
