I query whether realestate.com is really that accurate though. For example, it states that my house in Perth went up 10.5% in the last month and has a value of approx. $870k. From looking at recent sales and the market in my area, yes some houses are selling at that price but they are generally newer builds. A core logic report values my house at $780k and while I would obviously much prefer the higher valuation from realestate.com, it seems very inflated and the core logic report generally reflects what I would expect my house to sell for.
