What Vendor Discounting actually captures

Vendor Discounting is the percentage gap between the original listing price and the final sale price. If a property listed at $800,000 sells for $760,000, the vendor discount is 5%.

Data providers report either:

  • The median vendor discount across all sales in a suburb over a period
  • The proportion of sales that traded below listing (vs at or above)

Both metrics tell the same story: how much pricing power do sellers have?

The bands that matter

  • Under 2% — sellers in control. Most properties sell at or above listing. Auction bidding often exceeds reserves.
  • 2–4% — normal market. Healthy negotiation. Neither side dominates.
  • 4–6% — softening. Buyers pushing back. Sellers starting to compromise.
  • 6–8% — cooling. Clear shift toward buyers. Rising vendor capitulation.
  • Above 8% — weak. Sellers cutting substantially. Often precedes headline price falls.

Perth currently sits at 1.2–2.0% across most suburbs — unusually tight, consistent with the broader low-DOM / high-D/S story.

Why Vendor Discounting matters more than it looks

The relationship is asymmetric: low vendor discounts almost always accompany strong markets, but high vendor discounts don’t always mean weak markets.

Low VD signals:

  • Listings are realistically priced
  • Buyers are willing to meet or exceed asking
  • Sellers have negotiating leverage
  • Future price growth is more likely

High VD can mean:

  • Market is weakening (most common interpretation)
  • OR sellers are starting with unrealistic prices
  • OR the mix of stock has shifted (more distressed or motivated sellers)

A suburb with 6% VD and rising DOM is definitely cooling. A suburb with 6% VD but stable DOM might just have aggressive listing agents.

VD as a leading indicator

VD tends to widen before headline price data shows declines. The sequence is usually:

  1. Buyer demand softens (measurable in D/S ratio)
  2. DOM starts to tighten, but from low base
  3. Sellers begin accepting lower offers (VD widens)
  4. Median sale prices start to fall
  5. Headline data catches up 2-3 months later

Investors watching VD data can often spot cooling 3-6 months ahead of the property commentary.

How to read Perth’s current VD

Perth’s sub-2% vendor discount across most suburbs reflects the extreme seller’s market currently in place. What matters for investors is the trend, not the level:

  • VD compressing further (e.g., moving from 1.8% to 1.2%) = market strengthening
  • VD stable (around 1.5-2.0%) = market at high but stable
  • VD widening (moving back toward 3%+) = early signal of cooling

When Perth’s VD eventually moves above 3%, that’s the signal interstate investor momentum is fading and a normalisation is underway.

Using VD in suburb selection

For each suburb, TopBurb tracks:

  • Current VD percentage
  • 12-month VD trend
  • VD quartile ranking within the city
  • Correlation between VD and median price (do periods of VD compression precede price gains?)

A suburb with declining VD and rising D/S is almost always in an early growth phase. A suburb with widening VD and falling D/S is usually in early decline — even if the headline median price hasn’t moved yet.

VD is one of the earliest honest signals you get. Most market participants don’t watch it. That’s the edge for investors who do.
