Auckland homeowners are facing a complex set of factors that could erode property values, extending beyond broad economic trends. While national house prices remain relatively stable, experts warn that seemingly minor issues – from unkempt neighbouring properties to the proximity of infrastructure – can significantly impact a home’s worth.
Property economist Ed McKnight, of Opes Partners, highlighted the impact of neighbouring properties. “If your neighbour’s property looks like a mess – overgrown lawns, rubbish piling up, cars on the front lawn – that could develop it harder to get a premium price for your property,” he said. “Buyers tend to pay premium prices for the dream home. If next door makes it seem more like a nightmare, then the price premium will fall.”
The issue isn’t limited to aesthetics. Construction activity next door can as well be detrimental. McKnight recounted a recent case in Ōrākei, Auckland, where a homeowner attempting to sell found their prospects hampered by a neighbour demolishing a house to build a five-story apartment building. “It was hard to get someone to pay a premium price for a property when there’s going to be noise and disturbance next door for the following three years,” he explained. He emphasized the lack of control homeowners have over such situations, noting that even a well-maintained property can suffer from a problematic neighbour.
Beyond immediate neighbours, broader development trends are also playing a role. Auckland’s townhouse boom, while addressing housing density, can temporarily devalue existing properties. Cotality chief property economist Kelvin Davidson noted that the intensification push, while government-driven, can reduce privacy and sunlight for established homes. However, Realestate.co.nz spokesperson Vanessa Williams suggested that in areas saturated with new townhouses, properties with gardens and garages might actually increase in value due to their relative rarity.
Environmental factors are also gaining prominence. Recent weather events have heightened awareness of flood risk, with approximately 20% of Auckland buildings located in flood-prone areas. Williams stressed the importance of buyers researching flood zones before purchasing, as properties in risky areas may command lower prices, and owners may be unaware of the risk until they attempt to sell.
Less obvious factors can also have a measurable impact. McKnight previously stated that properties within 250 metres of power lines could be worth up to 20% less, although the impact diminishes with distance. He also found that power lines blocking a view could reduce a property’s price by 27%. Simple monopole cell towers had no discernible impact, but “armed monopoles” – those with antennas – could lead to a 10% discount for nearby homes.
Aircraft noise and proximity to correctional facilities can also affect values. While a 2018 report on new Auckland flight paths indicated no impact on property prices, Davidson noted that homes consistently overflown by planes can face challenges. Similarly, a UK survey found that 36% of people would live near a prison, but half would expect a price discount of almost a third to do so. However, Davidson also pointed out that prisons can bring employment to areas with limited opportunities.
Recent issues with sewage ponds in Christchurch, causing offensive odours and health concerns for residents, highlight another potential devaluation factor. While reports indicate no immediate impact on property values, the situation remains ongoing.
