Given the $9,800,000 ask, is this worth your time?

Why this ask?

  • FactListed for sale, asking $9,800,000(Listing record · 23 July 2026)
  • FactLand 3,233 m²; no building size recorded.(Property record)
  • CalculationAsk is 295% above the Wahroonga median recorded sale ($2,480,000, n=38, last 12 months).(Districts calculation from recorded sales)
  • CalculationIf it leased at Wahroonga's advertised median rent ($1,000/wk), implied gross yield would be 0.53% — this is not a rent for this listing.(Districts scenario calculation)

What could make it worth more?

No upside evidence detected in the data Districts holds for this lot.

What could make it worth less?

No detected risks — but see the checklist: absence of evidence is not an all-clear.

What should you verify next?

  1. 1Official planning layers are still retrieving for this parcel — check back before relying on zoning or overlay absence.
  2. 2No hazard layer has been retrieved — confirm flood, bushfire and heritage exposure from council mapping before an offer.

Each line above is labelled. A fact is quoted from the named source, with its date. A calculation is worked out by Districts from those facts — you can check the arithmetic. An interpretation is Districts' opinion of what the evidence means, not a fact, a valuation, or advice. Anything we haven't retrieved yet is marked as missing rather than treated as a pass.

Estimates only, at standard investor rates — no first-home or owner-occupier concessions applied. Not included: lenders mortgage insurance (usually applies when borrowing more than 80% of the price), loan application and settlement fees from your lender, the foreign-purchaser duty surcharge, and building insurance — in Queensland the property is at your risk from the first business day after signing, not from settlement. Verify with your conveyancer.

Stamp duty and transfer fees: New South Wales schedules from 2026-07-01. Ongoing council rates and land tax are not included.

Capital growth

NSW

Why this lot, not just this suburb

Why could this property outperform?

Planning layers have not been retrieved for this property yet. A suburb median or growth rate is not a reason this particular lot would outperform. Funded catalyst catchments are not loaded. A TOD badge is not this product.

What could kill that thesis?

Confidence: low

Official flood overlay has not been retrieved (pending). Missing layer is unknown, not “no.” NSW has a statewide DA API. Nearby (100–800 m) applications are not loaded for this property yet.

Rental

Income, competition, and yield

What will it realistically rent for?

Confidence: low

No advertised rent is recorded. Suburb median rent $1,000/week — not this address. An inferred likely-rent range is not shown until official bond series are loaded for this dwelling type and bedrooms.

What competition will it face?

Current comparable rental listings within 400 m of this lot are not loaded. NSW has a statewide DA API. Nearby (100–800 m) applications are not loaded for this property yet. Supply pressure needs comparable listings near this lot plus a nearby DA pipeline. Neither is loaded. Suburb vacancy or leased-tape days are not this property’s competition.

What does the yield actually look like?

Confidence: low

Gross yield if leased at the suburb aggregate is 0.5%. The yield that matters is the one on achieved rent, which has not been inferred for this address. Net yield (land tax, rates, insurance, vacancy) is not loaded. NSW net yield needs land tax and VG inputs that are not loaded. Gross yield from listings is not net yield.

Verdict

What this means for this property

Districts view

Not enough official evidence yet to underwrite this as an investment.

Detail

The same ten questions apply to every property. Missing flood, nearby DAs, achieved rents, or lot geometry is unknown — not “no.”

Do not treat a suburb median, an advertised yield, or a listing score as the case for this lot.

The evidence loaded so far isn't enough on its own to change a buy, offer, or walk-away decision for this property.

Evidence

What is known for this property

Districts asks the same ten questions of every property. If one shows as unknown, that data isn't published for this state or hasn't been loaded yet — the question stays visible so you can see exactly what's missing.

1 of 10 questions answered so far

  • Development optionality of this lot

    Unknown

    Planning layers have not been retrieved for this property yet.

  • Nearby development pipeline

    Unknown

    NSW has a statewide DA API. Nearby (100–800 m) applications are not loaded for this property yet.

  • Honest achievable rent

    Knownlow

    This is not “bond data says this address leases for $X.” The comparable figure is a suburb advertised/median rent, not this property. Official bond files (postcode or suburb × type × bedrooms) are not loaded yet.

  • Rental supply pressure

    Unknown

    Supply pressure needs comparable listings near this lot plus a nearby DA pipeline. Neither is loaded.

  • Why is this cheap?

    Unknown

    The constraint stack has not been retrieved for this lot, so Districts cannot explain a discount versus land size.

  • Lot-level flood

    Unknown

    Official flood overlay has not been retrieved (pending). Missing layer is unknown, not “no.”

  • Catalyst exposure

    Unknown

    Funded catalyst catchments are not loaded. A TOD badge is not this product.

  • This lot's DA history

    Unknown

    Development applications have not been queried for this parcel.

  • Statutory land value versus ask

    Unknown

    NSW Valuer General land values are not loaded for this property yet.

  • Net yield / holding costs

    Unknown

    NSW net yield needs land tax and VG inputs that are not loaded. Gross yield from listings is not net yield.
