What should you know about this lot before spending serious money?

Why this property?

  • FactLast recorded sale $1,530,000 (26 Oct 2025).(Recorded sale)
  • FactLand 351 m²; no building size recorded.(Property record)
  • CalculationRecorded House sales in Rostrevor (last 5 years) with land size: median $2,147/m² of land (n=105). Districts calculation from recorded sales — not a valuation.(Districts recorded sales)

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.

Capital growth

SA

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.” Nearby development applications are not loaded. This lot’s own applications are a separate question.

Rental

Income, competition, and yield

What will it realistically rent for?

Confidence: low

No advertised rent is recorded. Suburb median rent $643/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. Nearby development applications are not loaded. This lot’s own applications are a separate question. 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

Yield cannot be shown without both a price and a rent figure. Net yield is not estimated from gross advertising copy. Net yield / holding costs are not estimated outside NSW without inventing land tax.

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

    Nearby development applications are not loaded. This lot’s own applications are a separate question.

  • 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

    Statutory land value is not available as free bulk data in this jurisdiction. Do not fake it with a suburb median.

  • Net yield / holding costs

    Unknown

    Net yield / holding costs are not estimated outside NSW without inventing land tax.
