— the upper register · twelve months —
Every recorded sale in the luxury tier (level 39 and above) of Premier Tower between May 2025 and May 2026 from publicly available registers. Forty-seven disposals catalogued. The lower thirty-eight floors are excluded — structurally distinct sub-market, materially higher turnover, lower per-floor pricing — their inclusion in any comparable-sales model would distort the result.

Position

Premier Tower rises seventy-six storeys above Spencer Street in Melbourne's western central business district. The architectural and pricing midpoint sits at level 38. Everything from level 39 upward forms the upper register — fewer trades, longer holds, materially higher per-floor pricing. Unit 5101 sits at level 51, thirteen floors above midpoint, in the mid-band of this register.

The most apples-to-apples comparators are presumed same-stack units on the "01" line — Unit 5101's exact column. Two such sales settled in the twelve-month window: 7101 (level 71) at $1,069,700 and 3801 (level 38) at $886,800 with a car space. These bracket the subject and anchor the primary estimate. Floorplan equivalence across the "01" line is inferred from unit numbering and is unverified at the cadastral level — see Section VI.

The Register · 12 Months

All Premier Tower disposals at level 39 and above between 13 May 2025 and 27 May 2026, as reported in the primary public sales register. The adjusted column re-prices each comparable to the subject's configuration (level 51, no car, 63 m²) at current market — applying car-space hedonic (−$75,000), level differential (+/− $2,500 per floor general; +/− $7,815 per floor for the "01" line corner stack, derived in-tower), and a time decay of −3.5% per annum based on observed in-building capital growth.

Method · Four Cross-Checks

Four independent angles. None is sufficient alone. Treated as cross-checks rather than convergent estimators — they all draw from the same underlying register and are therefore correlated. The role of multiple methods is to surface dispersion, not to validate a point estimate.

— Approach A · "01" Line direct anchor —
Same stack — presumed same floorplan
n=2 · small-sample caveat applies
Per-floor coefficient from 7101 vs 3801 spread (33 floors): $7,815 / floor
Caveat: derived from n=2; standard error is large.

From 7101 (L71): $1,069,700 − 20×$7,815 = $913,400; ×0.965 time = $881,000
From 3801 (L38): $811,800 + 13×$7,815 = $913,400; ×0.968 time = $884,000
"01" line mean: $882,500
Approach B · Broad 2BR/2BA sample · adjusted
17 direct matches · level & time adjusted
Mean of 17 adjusted: $860,177
Median: $846,900
Trimmed mean (excl. high & low): $854,300
Approach C · Price per square metre
cross-check via $/m² · industry-standard normaliser
Inferred sqm of comps (Premier Tower standard floorplates):
— "01" line corner 2BR: ~70 m²
— "06/07" line corner 2BR: ~63-65 m²
— "02/03/04/11" compact 2BR: ~55-58 m²
Implied $/m² for upper register 2BR/2BA: $13,200 – $14,800
At midpoint $13,800/m² × 63 m² = $869,400
At lower bound $13,200/m² × 63 m² = $831,600
At upper bound $14,400/m² × 63 m² = $907,200
Caveat: sqm of comps inferred, not measured — see Section VI.
Approach D · Settlement-slippage adjustment
advertised prices typically 2 – 5% above settled in soft market
Public-register median of adjusted set: $854,300
Apply −3.5% settlement slippage haircut: ×0.965

Disposition · Economics

At the base-case clearing price of $855,000, transaction costs absorb approximately $23,000 — selling commission 2.0%, marketing $4,000, conveyancing $1,800. Net cash proceeds approximate $832,000. The subject is held against a $473,000 senior mortgage; equity released on close approximates $359,000.

Gross Proceeds

Net to Vendor

Equity Released
$359,000
after mortgage payoff

Versus the original acquisition price of $851,000, the base case clears effectively at par. Bear case ($795,000) yields equity release of approximately $300,000. Bull case ($895,000) yields approximately $399,000. The capital-at-risk gradient between bear and bull is therefore $100,000 — the principal range of negotiation leverage.

Limitations · Adversarial Review

This dossier rests on a public-register dataset. It is materially less reliable than a sworn certified-practising-valuer report. Below is a candid inventory of structural weaknesses — investors should weigh these before treating any figure above as authoritative.

— Statistical fragility —
The $7,815 per-floor coefficient driving Approach A is derived from two data points. The standard error on that slope is large and unquantified. If either anchor was a motivated or distressed sale, the "01" line analysis collapses to n=1 and the central estimate could move materially in either direction.
— Unverified floorplan equivalence —
The "01" line same-stack assumption is inferred from unit numbering, not from cadastral plans. Premier Tower may have mirror or layout variations across the 33-floor span between the two anchors. Verifying this requires access to the building's title plan or developer floorplate documentation.
— Area inference not measurement —
Square-metre figures for comparables are inferred from Premier Tower standard floorplate conventions, not measured per unit. A single 5 m² mis-estimate at ~$13,800/m² shifts the implied value by approximately $70,000. This is the largest unaddressed variable in the model.
— Advertised vs settled —
Public-register prints are last-known advertised figures, not settlement-confirmed. Soft markets typically print 2–5% above settlement. Approach D captures this generically; instrument-grade settlement data would refine it.
— Bottom-half freefall signal —
Lower-register prints show an annualised pace of decline of approximately −22% over the most recent two-month window (April 2026 sale below February 2026 sale despite higher floor). If this contagion crosses the midpoint, the entire upper-register estimate moves down by 6 – 10% over the next 90 days. The bear scenario assumes 30% contagion transmission.
— Survivorship —
The register shows what sold. It does not show what was withdrawn, passed in at auction, or relisted at lower prices. The current building "for sale" register shows ten listings — modest supply overhang exists. The market may be thinner than closed-sale velocity implies.
— Subject-specific factors not captured —
Aspect, view orientation, finish, furnishing, current owners-corporation fees, days-on-market for the subject itself, and any building-defect status (cladding rectification, structural matters) are not modelled. Each can move the achieved price by ±$30,000.
— Recommended verification —
Cross-validate against settlement-grade paid data sources. Commission a sworn certified-practising-valuer report (approximate cost A$500) before the Statement of Information is finalised under the Estate Agents Act 1980 (Vic). Treat figures above as a structured opening posture rather than as a binding valuation.
