Due diligence is the essential research you do before buying a property to avoid costly surprises and make an informed decision.

Key checks involve reviewing important documents with your legal expert, including:

- A LIM Report for council information and risks

It's also vital to research the area, check council rates, and confirm your finance pre-approval is in place before making an offer.
