While checking that the weeds had been killed (seems like they haven't), we also decided to go have a look at Metricon's display they were auctioning off for charity just four streets up from my block. It was more or less the same build, but slightly bigger - a Delta 24 on a 12.5x32m block. Most of it was much the same, though the electrical throughout was very basic, with tiles rather than timber.
The auction was a bit of a sad state though - not only were there only about 10 groups of people turn up, many really were there just to have a look. One of the sales agents had a bit of a chat with me, and asked how much I thought it would go for: "Oh, probably around 386, give or take". "Give or take? That's a very specific number". :)
As for actually bidders? Only a single bid at $380k, so I felt sorry for her. To put in any specific number and then not have anyone willing to challenge it basically means you could have said less.
Says a lot about the current market though since this one only just managed to sell.
