Stop Looking at the Performance of House Prices

Key Takeaways

  • 1City-wide house price statistics hide significant suburb-by-suburb variation.
  • 2Price movements under 10% are normal market fluctuation, not meaningful trends.
  • 3Historical price data is less valuable than current knowledge of what is available at your price point.
  • 4Create a ranked feature priority list and score properties during viewings to make objective decisions.

Almost every potential house buyer will ask "what are house prices doing at the moment?" This concern stems from not wanting to purchase a property today only to watch its value decline.

Almost every potential house buyer will ask "what are house prices doing at the moment?" This concern stems from not wanting to purchase a property today only to watch its value decline significantly soon after.

The Problem with Data on House Prices

Most homebuyers rely on city-wide house price statistics to inform their decisions. However, these broad metrics mask substantial variation within individual suburbs. As an example, December 2019 data showed Auckland with a -0.1% change overall, but specific suburbs performed vastly differently-Grafton rose 4.4% while Westmere dropped 10.4%.

Why Suburbs Vary Significantly

Several factors explain price divergence across neighborhoods:

  • Infrastructure improvements (like new motorways or tunnels) increase accessibility
  • Previous overvaluation or undervaluation correction
  • Major local business closures affecting employment and property demand

Reconsidering What "Price Drop" Means

The author argues that movements under 10% represent market fluctuation rather than meaningful decline. A $800,000 property valued at $760,000 might still sell for the original price if buyers find it sufficiently desirable.

Recommended Strategy for Home Buyers

Rather than monitoring price trends, prospective buyers should:

Step 1: Determine Affordability - Consult banks or mortgage brokers to establish what price range you can realistically purchase within.

Step 2: Attend Numerous Open Homes - Visit at least 20 properties in your approved price range to understand what features you receive at your budget level.

Creating a Feature Priority List

Develop a ranked list distinguishing "must-have" from "nice-to-have" features, then score each property during viewings.

Key Takeaway

"Historical data is meaningless. The goal is to know when you have found a good deal by having good, current knowledge of what is available at your level of affordability."

Why are city-wide house price statistics misleading?

Broad city-wide metrics mask substantial variation within individual suburbs. For example, while Auckland showed -0.1% overall, specific suburbs varied from +4.4% to -10.4%.

What is considered a meaningful house price drop?

Movements under 10% represent market fluctuation rather than meaningful decline. A property valued slightly lower might still sell for the original price if buyers find it desirable.
