Due diligence is the essential process of checking a property before you buy to avoid costly surprises. It involves personal research into the area and affordability, alongside reviewing key documents with your legal expert.

Essential checks include a:

- LIM Report for council information on consents and risks.

- Builder's Report to identify structural or maintenance issues.

- Valuation Report to assess market value.

- Report of Title to confirm ownership and land restrictions.

Securing finance pre-approval is also a critical part of this process.
