In the UK there are several free websites you can use to find historical house sale prices for an area
Sites like this one:
http://www.houseprices.co.uk/
where you just stick in a postcode and it gives you the historical sales for that area, prices, whether the place was a flat, semi, terrace, etc.
e.g.
http://www.houseprices.co.uk/e.php?q=RG1+2PU
Is there a similar service in NZ?
QV looks the closest, but as far as I can tell it charges nearly $20 for that sort of info. Is there anywhere does it for free?
cheers
