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

Why this property?

  • FactLast recorded sale $842,000 (25 Sept 2025).(Recorded sale)
  • CalculationLand 700 m² against a 140 m² dwelling — the land is most of what is being bought.(Districts calculation)
  • CalculationRecorded House sales in Seacombe Heights (last 5 years) with land size: median $1,143/m² of land (n=41). Districts calculation from recorded sales — not a valuation.(Districts recorded sales)

What could make it worth more?

  • InterpretationA large lot with a small dwelling means the value case rests on the land and what the zone allows on it, not the house.
  • FactZoned Hills Neighbourhood (HN) under the Planning and Design Code.(Location SA · 31 Aug 2026)

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. 1No 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?

Confidence: low

Zoned Hills Neighbourhood · HN (Planning and Design Code). Official parcel area about 698 m². Dual occupancy is not confirmed from the controls loaded for this lot. Two-lot subdivision is unknown without minimum lot size and frontage. This is a screen, not a planning certificate. Zoning and lot facts are a starting point, not proof this lot outperforms the suburb. Funded catalyst catchments are not loaded. A TOD badge is not this product.

What could kill that thesis?

Confidence: low

Flood overlay has not been queried for this lot. Missing layer is unknown, not “no.” Street frontage and true lot geometry are not confirmed without open cadastre. Minimum lot size is not loaded, so two-lot subdivision is not confirmed. 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 $640/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.

3 of 10 questions answered so far

  • Development optionality of this lot

    Knownlow

    Zoned Hills Neighbourhood · HN (Planning and Design Code). Official parcel area about 698 m². Dual occupancy is not confirmed from the controls loaded for this lot. Two-lot subdivision is unknown without minimum lot size and frontage. This is a screen, not a planning certificate.

  • 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?

    Knownmedium

    Official parcel about 698 m² — land size can look like optionality. No material overlays were returned that would explain a discount. That is not proof the price is fair. Nearby DAs, easements, and flood-layer gaps can still explain a cheap-looking listing — those are not all loaded.

  • Lot-level flood

    Unknown

    Flood overlay has not been queried for this lot. 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

    No DA adapter returned applications 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.

Listing material

Listed by Harris Real Estate Blackwood

A fresh start in a quiet enclave that holds the seaside close…

A vacant block is one thing. A generous 700sqm parcel with a 19.04m frontage (approx.) at the end of a quiet enclave? That represents an entirely different calibre of opportunity.

This is your rare chance to redefine the story on Crystal Road. With the existing three-bedroom residence beyond revival, the stage is perfectly set for a striking new architectural build (STCC) that takes full advantage of the expansive proportions and leafy outlook.

Framed by not one but two reserves, daily life begins on serene green trails that weave seamlessly into your morning routine, while quality schools, Westfield Marion, and the coastline all sit within easy reach.

Read the full description

For the astute buyer, the possibilities extend even further… whether undertaking an extensive renovation to breathe new life into the existing home, or designing a bespoke family residence from the ground up, this address promises exceptional versatility.

Whatever the vision, this unique allotment offers a rare equilibrium – seclusion, convenience, and the scope to create something truly remarkable.

A fresh beginning? There could be no better place to start.
