Property Advisory for Upsizers — Moving to a Bigger Home

June 23, 2026

Upsizing is one of the most complex property transactions most Australians will undertake. You’re selling one home and buying another — often simultaneously — with significant financial and logistical pressure on both sides of the transaction. Collings Property Advisory gives upsizers expert guidance on both transactions at a fixed fee of $4,500 + GST per side.

The Problem Upsizers Face

Most upsizers make two critical errors: they either sell too cheaply (because they’re in a hurry to buy) or they buy too expensively (because they’re emotionally committed to the upgrade). Without independent guidance on both sides, upsizers consistently leave money on the table.

Common Mistakes Upsizers Make

  • Selling before securing the next property, creating pressure to buy quickly
  • Buying before selling, creating bridging finance costs and pressure to sell cheaply
  • Not negotiating hard enough on the purchase because they’re emotionally committed
  • Not understanding the true cost of upsizing — stamp duty, moving costs, renovation
  • Choosing the wrong agent to sell the existing home

Frequently Asked Questions

Should I sell first or buy first when upsizing?

This depends on your financial position, the market conditions and your risk tolerance. Collings Property Advisory will help you assess both scenarios and choose the strategy that best suits your situation.
