54 Duffy Ave, Thornleigh

VG property id 3017528 · spans 52 street addresses

This is a subdivision-scale land record, not a single building. The NSW Valuer General keys 52 street addresses of this estate to one record, so every figure on this page spans the whole subdivision. It is kept for reference and is not part of our building index — each address has its own property page.

This record spans 52 street addresses: 37 Sefton Rd · 54 Duffy Ave · 20 Silver Ash Way · 18 Silver Ash Way · 2 Poinsettia Way · 28 Silver Ash Way · 12 Melaleuca Way · 3 Gum Tree Way · 2 Gum Tree Way · 4 Silver Ash Way · 5 Jarrah Way · 3 Poinsettia Way · 16 Allamanda Way · 13 Silver Ash Way · 9 Wild Ash Way · 3 Allamanda Way · 5 Cassinia Way · 19 Silver Ash Way · 31 Silver Ash Way · 3 Jarrah Way · 18 Allamanda Way · 5 Dryandra Way · 2 Wild Ash Way · 15 Allamanda Way · +28 more. Sales, resale and turnover figures on this page cover all of them together — the NSW Valuer General keys every lot's sale to this one record.

This building has 69 recorded sales since 2014; 83% of its 12 tracked resales sold above the owner's purchase price. Every figure below is a government record with its source named — and the last section lists what the public record cannot tell you.

What this dossier cannot tell you

Stated so a gap never reads as a clean bill (rule 7's positive form — silence is not evidence):

The strata books. Levies, the capital-works (sinking) fund, insurance, AGM minutes, and any defect claims in progress are not public records. Only a strata report — a paid inspection of the owners corporation's own books — has them. If you are serious about a unit here, buy that report; nothing on this page substitutes for it.
When the building was actually completed. No registration date is held for this building. Occupation certificates aren't in our sources; a conveyancer can obtain them.
Bedrooms on sales records. The Valuer General publishes no bedroom counts, so the sales above are every configuration pooled — a $732k sale and a $1.38M sale may be different-sized homes, not a price swing.
Why any individual vendor is selling. The patterns above are the building's record; no line on this page is a claim about a particular home or owner.
