Due diligence is the essential research you conduct before buying a property to avoid costly surprises. This process helps you make an informed and confident decision.

Key checks include reviewing a LIM Report for council information, a Builder’s Report for structural issues, a Valuation Report for market value, and the Report of Title for ownership details. Also, consider if the area and property fit your long-term plans. Securing finance pre-approval is another critical step in your due diligence.
