How to Know If a House Is Overpriced in NSW

The Overpricing Problem

Not every asking price reflects reality. Some properties are priced 10–20% above what comparable homes in the area actually sold for. Others are strategically underpriced to attract competitive bidding. Without data, you can't tell the difference — and that uncertainty is what costs buyers money.

An overpriced property isn't just a bad deal. It's a financial risk. If you pay above the local comparable range, you may find yourself in negative equity if the market softens. Your mortgage lender will likely value the property at what the data supports, not what you agreed to pay — meaning you could face a valuation gap at drawdown.

How to Check: Compare Against Closed Sales

The only reliable way to assess whether a property is overpriced is to compare its asking price against what comparable properties in the same area actually sold for. Not what they were listed for. Not what the agent says similar properties are "worth." What buyers actually paid, as recorded in the NSW Valuer General.

Here's what to look for:

• Percentile position — If the asking price sits above the 75th percentile of comparable closed sales, the property is at the upper end of the local market. Above the 90th percentile, it's likely overpriced relative to transaction evidence.
• Price per square metre — Compare the asking price per m² against the median $/m² of recent closed sales nearby. This normalises for size differences and gives a clean comparison.
• Days on market — Overpriced properties tend to sit on Domain or MyHome for longer. If a property has been listed for 90+ days without a sale, the market is telling the seller the price is too high.

Red Flags That Suggest Overpricing

• Asking price is 15%+ above the median closed sale price for comparable homes in the area
• Few recent transactions nearby (thin market), making it easier for sellers to set aspirational prices without market correction
• The property has been relisted or had a price reduction — this often indicates the original asking was too high
• Agent emphasises "unique features" or "potential" rather than comparable evidence — because the comparables don't support the asking price
• The price per m² is significantly higher than neighbouring closed sales of similar type and condition

What to Do If You Suspect Overpricing

If your research suggests a property is overpriced, you have several options:

1. Bid below asking — anchor your offer to what the comparable data supports, not the inflated asking price
2. Present your evidence — sharing Valuer General comparable data with the agent can reset expectations (agents respond to data)
3. Wait it out — overpriced properties eventually reduce or are withdrawn; patience is leverage
4. Walk away — the most powerful tool in any negotiation is the willingness to say no
