Given the $450,000 ask, is this worth your time?

Why this ask?

  • FactListed for sale, asking $450,000(Listing record · 4 Feb 2025)
  • FactLand 1,955 m²; no building size recorded.(Property record)
  • CalculationRecorded Land sales in Tumby Bay (last 5 years) with land size: median $173/m² of land (n=38). Districts calculation from recorded sales — not a valuation.(Districts recorded sales)
  • CalculationAsk is 17% below the Tumby Bay median recorded sale ($540,000, n=23, last 12 months).(Districts calculation from recorded sales)
  • CalculationIf it leased at Tumby Bay's advertised median rent ($434/wk), implied gross yield would be 5.02% — this is not a rent for this listing.(Districts scenario calculation)

What could make it worth more?

  • FactZoned Neighbourhood (N) under the Planning and Design Code.(Location SA · 2 Sept 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.

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: South Australia schedules from 2026-07-01. Ongoing council rates and land tax are not included.

Capital growth

SA

Why this lot, not just this suburb

Why could this property outperform?

Confidence: low

Zoned Neighbourhood (Planning and Design Code). Official parcel area about 1,331 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 $434/week — not this address. An inferred likely-rent range is not shown until official bond series are loaded for this dwelling type and bedrooms. No recorded off-street parking — often a discount versus the suburb median for the same beds.

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

Gross yield if leased at the suburb aggregate is 5.0%. 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. 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.

4 of 10 questions answered so far

  • Development optionality of this lot

    Knownlow

    Zoned Neighbourhood (Planning and Design Code). Official parcel area about 1,331 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 1,331 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

    Knownmedium

    No development applications were returned for this parcel. That is not a statement about nearby lots.

  • 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.

The potential is great, with the block being leveled and ready to build -

you could also be thinking of subdividing and building your home and some investment properties. This is the perfect location.

With very limitied blocks in the town center ready to build be sure to take a serious look. Near by comparison land have been selling, but are less than half the the size.

Endless potential
