When purchasing real estate, I recommend Buyers obtain Pest and Building Inspections (and a Strata Records inspection if purchasing strata titled property) prior to entering into a Contract or bidding at an auction.
You may nominate your preferred Pest, Builder or Strata Consultant or see my Links page for Consultants I can personally recommend for properties within the Hunter region.
Having read many Pre-Purchase Inspection Reports over the years, I will be able to assist you in this regard.
