Dids – you mention the Kyero figures – personally I wouldn’t give Kyero any credence whatsoever.
They publish asking prices (so there can be huge discrepancies between sensible and not) and they only base their figures on what sometimes are extremely limited numbers of property.
The village I live in has an average price of 600k – great! Not really, they based that on one property!
So, personally, I can only suggest one use for the paper that comes out of a printer with Kyero figures on it. 😉
