Your buyer evidence guide

Understand the home before the offer.

The useful records, what they mean, and the questions they leave open. Start here, then explore the evidence below.

The listing we observed

3 bedrooms · House

Listing details describe the advertised home. They do not verify its condition or approved use.

How much price evidence fits

43 sales in the wider suburb/type pool

The wider pool is not a set of identical homes. Bedroom count, condition and location within the suburb affect comparability.

Published auction evidence · model trained through an unavailable cutoff

What deserves a closer look

  • price cut $200k — to $1.4M
  • asking $1.6M
  • first tracked by our radar (the portal doesn't publish its list date)

These are recorded events, not evidence of the seller's motivation.

What we still cannot tell you

  • No settled-sale history is available in this page's records. This does not mean the home has never sold.
  • Direct price support is limited. Read the comparable sales and the estimate's uncertainty together.
  • Public records and an automated estimate cannot establish whether the home is defect-free, what the contract contains, or why the owner is selling.
Questions to take to the inspection

Use these with the agent and your independent advisers. An answer is something to verify, not a fact we have recorded.

  1. Which recent sales are most comparable to this home, and how do their size, condition and position differ?
  2. What repairs, alterations or water issues are documented, and what can an independent inspection verify?

The estimate is a model output. The records are evidence. Your inspection and document checks fill the gaps.

Is the asking price plausible?

This is a comparison with the evidence we hold, not a valuation or a recommended offer.

Confidence: Low — based on 43 comparable auction sales (4 of this exact configuration) · model runs ±11% for this configuration · confidence held at Low — under 20 same-configuration sales · the model's typical miss is ~11% against published results — every hit and miss

How this estimate was made
  • Method: Comparable-sales grid · version 2026-08-11-v5
  • Inputs used for this home: no per-address records were available; this uses location and configuration only
  • Comparable support: 43 sales in the wider suburb/type pool; 4 of this exact configuration
  • When to be more cautious: Condition, aspect, renovation and the contract are not model inputs and can move the eventual sale price.

Where every number comes from
  • Fair value: Comparable-sales grid 2026-08-11-v5 — trained on 146,492 published auction sales; configuration-level (suburb × type × beds), not an appraisal of this exact home
  • Comps: published Domain auction results for Adelaide — suburb × configuration matches, not hyper-matched to this address
  • Evidence trail: tracked by our radar from portal listings, web-archive checks and published auction results — each entry dated

What changed recently?

  • 24 Aug 2026 first tracked by our radar (the portal doesn't publish its list date)
  • 24 Aug 2026 asking $1.6M
  • 9 Oct 2026 price cut $200k — to $1.4M
  • 11 Oct 2026 on market 47+ days — first tracked by us, a lower bound

What to inspect before you offer

  • Condition, aspect, renovation and the contract — these can materially change price, and the estimate cannot see them.

These are due-diligence prompts, not a verdict on this property.

⏱ Days on market — this campaign

47 days since our daily sweep first saw this listing.

The portal's own campaign may have started slightly earlier than our first sighting. Longer campaigns tend to mean more negotiating room — the board's "Longest listed" sort exists for exactly that reason.

Similar properties — on the market now

The 6 listings above are on the market now: same house category, within 1 bedroom of 3, asking within 20% of this one, in Adelaide or a suburb whose centre is within 3 km — ordered by how close the asking price is. That is the whole rule: a filter, not a recommendation, and nothing here judges which home is better.
