Quick Answer
In Sydney, the cost of moving is often more than $150,000 in fees you never get back — stamp duty, agent commission and moving costs. For many families, an attic conversion delivers the extra space they need for a similar or lower cost, while keeping their suburb, school and neighbours.
The Hidden Cost of Moving
Upsizing sounds simple until you add up the transaction costs. On a typical Sydney upgrade, the “dead money” you spend just to move — before you've gained a single extra square metre — looks like this:
Figures are indicative for a Sydney purchase around the $2m mark and will vary with price and lender.
Convert & Stay
Add the space you need to the home you already love — no stamp duty, no agents.
- Keep your suburb, school and community
- No stamp duty or selling fees
- Invest in your own asset, not fees
- Stay in your home during the build
Sell & Move
A bigger home can be the right call — but only once the true costs are on the table.
- Makes sense if you want a new location
- Best when you need much more space
- Suits a change in lifestyle or work
- Factor in $150k+ of non-recoverable fees
