Common Seller Mistakes: Michael Tomadakis’ Evidence-Based Advice

September 5, 2026

After 12 years in real estate and hundreds of auctions, Michael Tomadakis has seen the same seller mistakes impact results time and again. As Collings’ Sales Executive and auctioneer, he shares the errors to avoid—and his top advice for preparing a home for market in the Inner North.

Most Frequent Seller Mistakes

  • Overpricing—setting expectations based on hope, not evidence
  • Not investing in property presentation (styling, repairs, cleaning)
  • Poor timing—ignoring seasonal or market trends
  • Choosing an agent for the highest appraisal, not honest advice
  • Failing to understand which sale method truly suits the property

Michael’s Seller Preparation Checklist

  • Seek realistic, evidence-based price guidance
  • Style and present the home to maximise first impressions
  • Ask for a clear sale strategy (auction or private sale—and why)
  • Fix minor issues buyers will notice
  • Understand your local competition

Why Transparency Matters

Michael is known for giving vendors honest advice, even when it goes against their preconceptions. Sellers are best positioned for success when they base their strategy on evidence, not just optimism.
