How To Bag A Bargain This Christmas

Published in Property & Home on 29 August 2008

This site promises to give you an accurate estimate of what your home is worth. But does it work? Emma Lunn finds out.

Do you fancy finding out how much your house is worth? Tempted to make a speculative offer on the pad down the road that isn’t even on the market? Interested in finding out what your friends paid for their place?

If the answer’s ‘yes’ to any of these questions then zoopla.co.uk could be for you. Set up by the founder of DVD rental service LoveFilm, Zoopla claims to be the UK’s first community property website.

In my opinion, it’s a gift for voyeurs and property porn addicts everywhere, because Zoopla provides free, instant value estimates on more than 26 million homes –- in other words the UK’s entire housing stock.

What I like about it is that, unlike other property search engine sites, Zoopla lists details of all the properties in the UK rather than just those on the market. As well as checking out what their place is worth, users can set a TemptMe! Price which is the price they would consider selling for or make a TemptMe! Offer on any home listed on Zoopla.

Basically the site gathers information from public sources and groups it all together. From historical sales prices from the Land Registry, economic trends and property characteristics in any given area, a proprietary algorithm (secret formula) calculates how much your house it worth today.

How accurate is it?

Let’s put it to the test.

I recently went through the remortgage process, and my new mortgage lender had valued my flat in south London at £286,000. I consider this to be a pretty accurate estimate – after all, unlike estate agents, it’s not in a lender’s interest to bump it up a bit.

But Zoopla says otherwise. After I’d typed in my postcode and located my flat, the site said it was worth a paltry £205,000. It also claimed the value was down £7,442 from a year ago but up £11,289 from two years ago.

£81,000 is a pretty big discrepancy in my opinion. As I live in a block of six flats which is one of four blocks making up an estate, I thought I’d check what my 23 neighbours’ – whose properties are pretty much identical to mine – are worth.  The results are a bit confusing. Despite Zoopla basing its figures on previous sale prices and local information, identical flats on my estate ranged in value from £187,500 to £245,000.

However, once users have ‘claimed’ their home it’s possible to add details to the site to get a more accurate estimate. I claimed my flat as my own and added details about the number of rooms, decorative state, heating, parking and outside space. Yet, the value of my beloved abode was only bumped up to £220,851, still more than £60,000 short of the recent lender’s valuation.

So how can my place be worth less than both the maximum value of identical flats and my recent valuation?  I had a new bathroom put in last year for God’s sake, and the whole place has been transformed from the dump it was when I moved in, to the trendy bachelorette pad it is now.

Zoopla itself says it relies on users inputting details to give more accurate valuations but despite doing so, my flat is still shown at a less than 80% of its true value.

So what are other people’s experiences? Has Zoopla got it right and I should simply face the fact that my flat is worth less than I like to think? Or are web valuations such as this not to be relied upon?

Emma, only by selling your flat can you establish its true, that is, market value. Your surveyor may have 'valued' it at £286k, but I suspect a buyer would be willing to pay much less than that in this environment. The different between the two figures would be your 'mark to market' loss.

'Your surveyor may have 'valued' it at £286k, but I suspect a buyer would be willing to pay much less than that in this environment.'

Notwithstanding the turbulent market conditions, my experience is the opposite.

The primary purpose of a remortgage valuation survey is to ensure the property provides sufficient collateral for the loan. The extension to this is that the lender could potentially make a claim against the surveyor should it become clear he over valued the property at that date (in the event of a loss incurred following repossession).

Therefore it is in the surveyor's interest to err on the side of caution.

Yes, I thought surveyors acting for lenders would err on the side of caution - that's why I'm confused. I could understand an estate agent giving a higher price but not a surveyer. I guess the only way to find out is market it for sale but that's a bit drastic...

I have just checked the price of two semi-detached houses on my road (attached to each other). They are identical in every way (save for decoration) and Zoopla values one at £348,000 and the other at £403,000. I suspect the discrepancy is in a large part due to when each of them was last sold. Zoopla must apply the area's average increase/decrease since that date. A case in point about how useful housing market statistics are when taken to the micro level.

I tried Zoopla the other day - on my own house and my Mum's house. I thought both values were conservative (lowish). However it was interesting to experiment with hypothetical home improvements eg put in double glazing and see how much difference it makes. The terms and conditions of Zoopla require honesty, but I think it's OK to do this as long as you don't leave any misinformation on the site at the end of the day.

Beware!
My central Edinburgh property is estimated by Zoopla to be worth £91,548. Two years ago it was valued for equity release at £450,000, and property in this specific area is continuing to rise in value.

Just tested my house price estimate and it is (bit depressing) but very accurate.

Sounds like there must be an error on your property jocktamson (probably a mistake in the Registrars of Scotland data) - you should contact Zoopla and get them to sort it out.

Mortgage appraisals do tend to overvalue property - don't know why - and don't think it is unreasonable to have a range of values for "identical" properties - they never are identical anyway - which way they face, views, security, decor etc.

I tested Zoopla for my house. It was quite easy to fill in the form and all went well until they asked me for my estimate of its value. I thought the idea was that they told me their estimate? (The site is in beta mode and not yet fully developed.)

So I gave an estimate which I think was too high in retrospect. The problem may be that the other side of my street has bigger houses which are worth more than my side, and that may have confused them as it is the same postal code as mine.

So bear that in mind if you're using it. In other respects the site is nice and brings a lot of info together. I particularly like the birds' eye views.

Using sale price and date can bit rough as it can depend on the gap between the date the price was agreed and the sale price as well as any enhancements of course. I agreed the sale price of my old house and purchase price of my new one in January '07 but the completion for these was in May '07 during which time prices went up significantly in the SE.

Mouseprice do something similar http://www.mouseprice.com/

Compared to what I what was agreed in Jan and paid in May these sites now say:

For my old house Zoopla say the price has gone up 6.2% whilst Mouseprice say 3.7%

For my new house Zoopla say the price has gone up 0.4% whilst Mouseprice say 4.2%

Quite a difference!

I purchased my current house 4 months ago at 210,400. Now due to seperation/divorce it looks like i will be selling it sometime in the near future, Zoopla estimates it at between 202,000 and 212,000. So i can only figure from this that its going to be the lesser of the 2 as house prices have fallen, but with a bit of luck i could still sell it and walk out debt free once all the solicitors and estate agents are done. Fingers crossed for the future!!!!

For the UK, Zoopla maybe something new. But in reality there is nothing new or innovative about it. Infact the entire website offering is more a less a mirror of www.zillow.com (long established and successful).
Zillow has - Make Me Move, Zoopla came up with TemptMe
Zillow has - Zestimate, zoopla came up with Zed-Index (Infact Z-Index was a possible name Zillow was going to use, but actually canned it for Zestimate instead - see bottom of page http://www.zillow.com/corp/About.htm)
etc etc etc
It is clear from my own perspective, that the founders have seen a successful US based web business, have essentially mirrored it's offering with a view to a possible acquisition by Zillow once they IPO.
Whilst there is absolutely nothing wrong with this (in fact I am all for this type of exit strategy), I do find it rather annoying when reading their about section, where they appear to claim to have conceived the concept of Zoopla all by themselves, when it is clear they did not. Richard Barton and Lloyd Frink (founders of Zillow) did.
So for all those wannabe Entrepreneurs, it is simple. Look at what other countries are doing, that the UK does not. Rip of their business model, go and see a VC, and they will give you 1.5m to get going.
