Mark Posniak looks at the benefits and drawbacks of automated valuation models
There are few in the industry who remain unfamiliar with the term ‘AVM’, or who don’t know what it stands for.
In the few years since automated valuation models (AVMs) have been available in the UK, they have taken quite a significant hold on the mortgage market. According to a number of estimates, they now account for up to 20 per cent of all mortgage cases. You only have to look at the trade press to see the extent of their uptake among lenders.
London Mortgage Company, Preferred and Southern Pacific Mortgages – all owned by Lehman Brothers – recently announced the launch of AVMs.
Platform has unveiled a ‘same-day’ mortgage offer using AVM technology and its Click online system.
Praxis Mortgages has teamed up with Kensington to launch its first product designed specifically for borrowers who want a fast-track offer using the new technology.
There are not many lenders who haven’t already got an AVM proposition in place, or who are not in the process of planning one.
Indeed, within the bridging sector, Cheval is shortly to link with UKValuation and become the first to have an AVM-backed bridging product that will greatly speed application turnaround.
The ins and outs
AVMs work on the basis of taking detailed statistical information such as property size, location, social statistics and demographics and translating them into a value. This information comes from established sources such as Land Registry, historical valuations and sales values and complex algorithms are then applied to the data resulting in a valuation.

A typical valuation will give an estimated value of a property and a probable value range showing an upper and lower limit with a 10 per cent margin either way. This takes into account factors such as the state of the internal structure, confidence in the marketplace and recent sales in the area. The valuation can then be modified in the light of the precise circumstances of the property, and is then given a confidence rating.
The convergence of AVMs with physical valuations has been helped by the recent release of up-to-date Land Registry figures, which has boosted the quality of data.
Currently, the UKValuation model returns nearly four out of every five valuations within 10 per cent of the reference value, which is a 40 per cent improvement on three years ago.
This impressively accurate valuation methodology has given the mortgage industry the confidence to embrace the technology, where in the past it might have been reluctant.
Right technology, right time
Lenders and brokers have also come to view AVMs as the right technology at the right time. The desire to deliver swifter mortgage offers has never been more marked and AVMs are a great tool in speeding up the process.
All sides of the industry want the certainty and convenience of rapid valuations. The traditional approach of appointing surveyors and then waiting for valuation reports has slowed the mortgage process and acted as a brake on case turnover.
The new technology takes out the uncertainty of what can be a two-week-long wait with certain mortgage lenders, and helps provide enhanced service; reductions in cost; and increased speed of turnaround. This is good for business in terms of referrals, repeat clients and case volume.
Speed is becoming a big differentiator for lenders. If you can get an offer to the customer quicker than your competitors, then you have an edge. The difference between an offer in hours and one in days will decide where a customer takes their business.
Fortunately, the coming of age of AVM technology has been recognised by the rating agencies for UK residential mortgage securities. This acceptance has been a key step forward for AVM credibility and is thanks to big improvements over the last few years in accuracy.
The rating agencies are apparently convinced that the difference between AVMs and previously-recorded conventional survey inspections is now very small.
Not without drawbacks
The AVM process is not without its drawbacks, however. Under-valuation and over-valuation can pose problems for lenders. If an AVM under-values a property, then this could ultimately impact the lender’s case volumes with too-low AVM valuations preventing a borrower and lender from proceeding.
If the AVM over-values a property, then the risk is an increase in default costs as the lender discovers that its security, as measured by the LTV, is significantly lower than was understood at the time the loan was agreed.
AVMs are currently most suitable for individuals who are looking to remortgage, or buyers who have a high level of knowledge about the property in question.
Some maintain that AVMs do not work on certain types of property. They say newly built houses and flats, or properties in isolated areas, cannot be accurately assessed. Many insist that buy-to-let properties also need to be traditionally valued, as AVMs cannot accurately predict rental income. However, it should be noted that the technology is still developing and a number of lenders have announced buy-to-let products backed by AVMs.

Some lenders question the impact AVMs will have on ‘Treating Customers Fairly’ (TCF). The concern is that, when a client is potentially at risk, the industry has to think about TCF. Either brokers in their advice, or lenders in their paperwork, have to highlight the risks of not taking out a conventional survey.
This last concern should have been allayed in part by the recent Financial Services Authority (FSA) ruling that lenders must have an independent valuer to assess AVMs. The FSA has ruled that, under Basel II, all results must be traced back to a suitably qualified individual who can offer an independent opinion on the risk.
This means the use of AVMs must be within a process that can be ascribed to an independent valuer.
Despite these teething issues, the popularity of AVMs can only grow. I expect their use to become much more widespread. The Council of Mortgage Lenders’ research predicts that they will account for 40 per cent of all mortgage valuations by 2012.
The issues outlined above will be overcome as the sophistication of the modeling advances. Buy-to-lets, new builds and flats will soon be accepted as suitable for the use of AVMs.
The genie cannot be put back in the bottle.

Technological development is leading to rapid changes in the way that professionals perform their business and we in the mortgage industry are no exception. One of the changes is the introduction of AVMs used in basic residential valuations - the times when lenders issued offers with a “subject to valuation” stamp are over, or at least can be over if a customer chooses so. Whether involved in a race to get a contract signed or trying to meet the deadline on a new build property deal, instant offers through AVMs can help those up against the clock as they are effectively removing the need for a physical valuation. AVMs can estimate the current market value of a home based upon various analytical methodologies and data elements e.g. comparable sales prices, home characteristics and historical property price appreciation, which enables lenders to issue unconditional & binding offers in minutes. Additionally funds can be released by lenders as soon as satisfactory certificate of title is received - AVMs clearly speed up the whole application to completion process and will become more and more important in our industry. Not only do they give the client certainty and speed, they also give brokers a competitive edge because they can quickly proceed to their next case. Some people say that there is an element of risk involved and their argument is based on the premise that physical valuations are “always right”. But those trying to knock AVMs probably can’t afford the technology themselves and it seems that they are hiding their lack of resources behind their indisposition. Obviously not all properties are suitable for an automated valuation - the more unique a property is the less data will be available on it. A thatched cottage in the Lake District will be more difficult to value using an AVM than a three bed Semi in North London. However, as time goes by and more data is gathered more and more properties will fall into the AVM net. Same applies to the Buy to Let market, as we gather more data about different rental yields in the UK, AVMs will become available for Buy to Let investors, too. Automated valuations are growing in acceptance and it’s clear that they will continue to do so. Any lender serious about offering genuinely competitive levels of service will need to embrace them fully. They have a huge potential, and the more data AVM providers like Hometrack collect about the UK housing market, the faster and more efficient the process becomes for everyone involved. To edeus and the other most advanced lenders, AVMs are synonymous with a high standard of service and other lenders will learn to recognise that. Those refusing to take them on board will fall further and further behind the levels of service being offered by their competitors and face a rapidly shrinking market.

Automated Valuation Models (AVMs) have received a substantial amount of attention in 2007 with a number of specialist lenders announcing their implementation. After significant development and testing by their providers AVMs have been welcomed by the great majority of industry pundits and their arrival in the mortgage market has been well documented.
Currently only a handful of lenders utilise AVMs and so it is early days to cast in stone what their future will be. One thing which does seem certain is that an increasing number of lenders are intending to implement AVMs in the future and as such their prospects look relatively rosy. Those utilising AVMs at present may do so under a maximum LTV limit reducing exposure and I am sure that they couple this with well structured and expert affordability models and risk modelling.
The FSA have recently issued their guidance on the use of AVMs, a confident nod to the expected prevalence of these valuations throughout the industry. Given that the monitoring of property values is intrinsic to risk management for any lender, the FSA's decision not to implement an industry-wide LTV limit is an encouraging tick in the box for AVMs.
Brokers have openly welcomed AVMs, and where they eliminate the five day turnaround time expected of a standard valuation, this optimistic position comes as no surprise. As far as consumers go, it's still early days for your average borrower to have a full grasp of the numerous benefits of AVMs.
With this is mind, many will continue to seek their brokers' advice when it comes to selecting an appropriate valuation method. Research from BM Solutions One Specialist Survey found that 86% of brokers believe that they should get a full choice of valuation, suggesting that although brokers expect increased AVM usage; it will not be at the total expense of conventional valuation reports.
Following the implementation of AVMs, the obvious benefit to brokers and consumers alike is that lenders can now issue offers at point of sale. In an ever competitive industry, this provides a valuable string to a lender's bow.
With AVMs accepted as a core valuation choice for the future market, it's important that we continue to educate consumers to appreciate the suitability of these valuations according to their circumstances.
Another significant step forward will be the use of AVMs for Buy to Let applications. Relying on the automated determination of rental assessment in addition to property valuation is big move for lenders, but one that is already beginning.
AVMs are still enjoying a honeymoon period in the market, but brokers have made it clear that there is a real expectation for all lenders to be able to provide the choice. As with anything in the dynamic mortgage market, it's impossible to accurately predict what the future holds for AVMs. But as more lenders look to implement AVMs, and others expand their usage across schemes, the future looks like it could be bright indeed.

AVMs are being heralded as the big breakthrough in mortgage lending, because they enable the offer process to be fast-tracked. There is no doubt that without AVMs instant point of sale offers would not have become a reality, but that doesn’t mean that AVMs are perfect in every instance.
To understand their strengths and weaknesses, you need to understand how AVMs work. In simple terms, a property’s value is assessed based on the value of similar property in the same geographical area. So, for example, a 3 bed semi on a housing estate which is opposite a similar house worth £280,000 and next door to another similar house worth £280,000 is probably going to be worth……..£280,000!
In circumstances such as low LTV remortgages, an AVM is good enough. Even for purchases where the buyer needs a quick offer, an AVM may be fine. However, there are circumstances where they don’t work quite as well.
If, for example, the property in question is of a unique design and there are no similar properties in the area against which an accurate comparison can be made, it may not be possible to provide an AVM. If the LTV is also very high, the lender may be unwilling to use an AVM. AVM providers such as Hometrack give a measure of confidence (Hometrack’s ranges from zero to seven with seven giving the highest measure of confidence and hence accuracy). For lenders who securitise mortgages, this level of confidence is particularly important. The proportion of securitised loans that use AVMs will increase over time, but on a gradual basis as investors and rating agencies become used to them.
It also needs to be remembered that, as useful as AVMs are in speeding-up the offer process, they give borrowers no insight into the true state of the property they are about to buy. A physical inspection of a property may still be required which will, of course, be an additional cost to the borrower.
For packagers AVMs are a double-edged sword. On the one hand, they threaten income because they remove the need to instruct a valuer. With margins under pressure, this is not necessarily good news. On the other hand, the ability to make a quick offer usually means the applicant is happy to proceed and less likely to pull out or go elsewhere. AVMs can therefore help reduce the number of aborted cases, which has to be good news.
Will the use of AVMs increase in the future? Inevitably, but they are not the perfect panacea that some industry commentators are making them out to be. They have their strengths but also their weaknesses and brokers as well as lenders need to bear both in mind when advising clients.
