I love the BOQ property app and use it all the time to get information I am looking for. But I know that the estimated sales prices are all over the shop and would never rely on them to be anywhere near accurate. My brother is pondering selling a house and I ordered a report on it, and also one on a house we own. Our property has a UCV of $760k and the estimated price range is $690k-870k with "high confidence". It would be a rare thing indeed for an inner ring property to sell for under the UCV. We had this property valued a year ago at $950k. The houses that this automated system used to compare with ours are each on blocks ranging from less than half to just over half the land size of our block. Houses look similar enough for a comparison. We have a large block, but they are not that rare that some computer could have searched for sold properties with larger sized blocks to compare ours with. How can a smart system (?) tell me the UCV is $760k and suggest sale price would be so far out? The emails I get from Onthehouse are worse. Our house photo is very old (midway through a renovation we did nearly 20 years ago - obviously no photos available since then as we've never sold or rented it). They give price range from $900k to $1m with a "low accuracy" comment, and that estimate may well be correct. We've just had a valuation done but haven't yet asked our broker for the value. But the "similar properties recently sold" they've used is for a two bedroom unit which sold last month for $270k. Someone needs to tweak the way the computer finds the comparable properties.
