How come land registry says haringey ( for example ) increased by 23.3% in the last year

But Zoopla says Haringey increased by only 13.78 % ?

if it pleases you for someone to say so then please take it from me that the higher estimate is unquestionably the more reliable of the two.

What I can't understand is why zoopla still refuses to take the land registry stats after the second year. Check the last two years on Zoopla, still only 18.12% for the last 24 months ?

How many major websites do you know who manages to get away with being so wrong on the key information they provide ?

I think there might be some sort of bug in zoopla.


My area has similar figures, i.e. LR 20%+ , zoopla circa 12%.


yet unquestionably the actual zoopla estimate on individual houses are moving in line with the LR figures.

Zoopla have advertised this information wrongly for as long as I can remember. If it's a bug how many billion pound websites continue to have a bug for so long without fixing it ?

not unusual, most companies with big websites and databases have extremely buggy software.


The problem is that if they have a problem in the software, rather than taking the extra time to fix it properly they will fix it quickly with a "workaround". yet further down the line the "workaround" will cause more problems and yet more workarounds are created.


Until eventually the whole system just becomes a collection of workarounds which cant be unravelled and eventually development on the site grinds to a halt as the developers have their hands full dealing with all the bugs that get reported daily due the previous workarounds.


It's why big IT projects are extremely prone to failure, especially in the public sector where everything is done on the cheap

It's just an Algorithm that needs tweaking, really not that hard.

according to the LR a flat in walthamstow sold for £165,000 in july 2013 and sold again for £1,000,000 4 weeks later.

That's a conversation I have at least once a week with a client, everytime there is an excuse why it can't be done.

Zoopla is a big pile of poo. For instance it currently tells me that my house is worth £5,427 more than I paid for it three months ago. However it also tells me that it has increased in value by £9,481 in the last three months (it knows what I paid for it as that has been published on the LR for a while now).

Still, nothing that can't be remedied. I will just tell it that the house now has an extra reception room, new wall paper and a loft conversion and it will go up by another £50k or so. Job's a good 'un.
