Are AVMS putting your clients at risk?

There are many elements of the homebuying process that could benefit from greater automation, but the rise of automated valuation models (AVMs) is an area where we should perhaps be concerned.

It’s worth remembering that a mortgage valuation is for the protection of the lender, not the borrower and the type of valuation undertaken therefore depends on that lender’s risk appetite and commercial demands. On a low loan to value (LTV) transaction on a low margin product, for example, a lender may be comfortable with a very light touch valuation and may indeed have a commercial imperative to take this route to minimise fees and ensure it achieves profitability on the deal.

Here's some information on the different types of valuation that are currently being used by lenders. You may also find it useful to visit the website of the International Valuation Standards Council, which is the independent global standard setter for valuation practice and the valuation profession.


An automated valuation model (AVM) is a statistical valuation of the property based on past performance of similar properties in the area. An AVM is the ultimate light-touch valuation, based entirely on data and an algorithm and lenders will not generally charge for an AVM. 

Desktop valuation

A desktop valuation is relatively new and is the next step on from an AVM, using a combination of online data, local knowledge and services like Google Street View. 

Drive-by valuation

The most light-touch physical valuation is a drive-by valuation, in which a valuer will literally drive past the property to check on the external condition and ensure that the property is consistent with its surrounding properties. 

Market Valuation

A full inspection is a physical inspection as part of the mortgage process and could cost between £200 and £1000. It is worth noting however, that this is still for the benefit of the lender and is not as comprehensive as a homebuyer report or building survey


Lenders are increasingly deferring to AVMs, particularly on lower LTV cases and often they don’t even offer buyers the opportunity to upgrade to a physical inspection of the property. Consequently, my experience of the market is that on half of valuations, nobody even goes through the front door to review the property.

This might seem advantageous for your clients, who see physical valuations as a hold-up in the homebuying process, but that isn’t necessarily the case.

If nobody is going into the property, who is going to point out that walls have been removed or a loft converted without meeting building regulations, for example. Or pick up on areas of poor condition that could be costly to rectify.

A lender might be happy to take on the risk, based on an AVM, but your client could be taking on a liability that they might not be able to afford.

In an environment of low property transaction volumes, there is greater emphasis on client retention by delivering exceptional customer experience and also maximising conversions. If you are not discussing the value of a physical inspection of a property, you could be letting your client down and may even leave yourself open to potential claims in the future from clients who claim,

“Why didn’t you tell me that I needed to have a survey done?”

Addressing whether or not a client should have a survey early in the process could even help to improve the success rate of transactions. Purchasers are currently required to confirm that a survey has been at least considered when they sign the title. The problem is that this is at the end of the process and can cause additional delays if, at this stage, they do decide they want the property to undergo a full inspection.

So, rather than wait for the tail end of a transaction when delays can be critical, raising the issue at day one can provide buyers with more confidence and help the process to run more smoothly. 

Not every buyer will want a physical inspection, but at least by talking about the options early on in the process, you can demonstrate that you are working in the best interests of your client and protecting their investment.

Examples of different types of property survey are available.

Here's what our customers say


Professional, efficient surveyors. Get the job done in a timely manner, had our survey back within 5 days of inspection. All team members I spoke with (Tiffany and Billy) were really lovely. Highly recommend. :)


I have only just started working with Stephen and he has already demonstrated the high levels of customer attention and dedication that this company has. The first impression he has caused is such that made me write this review. I have no doubt that the continuous service will be of same level. Looking forward to working further with Stephen. Well done!

Lease extension - I found Daniel Grove very professional and had an excellent understanding of all aspects relating to this transaction. Advice was invaluable, and it was nice to come across someone who did exactly what they said they were going to do. Would not hesitate in recommending the firm and Daniel to anyone who has a lease to extend.

Petros Kyrkilis

Amazing job and fully professional treatment. The surveyor went above and beyond to check for everything, when he could have easily claim lack of access. In addition he was more than happy to answer questions over the phone and be there to explain the steps.

Lynn Wilson

Within 48 hours I received my detailed report from Joe Arnold which enabled me to see the property as it was and not through rose-tinted glasses! The report highlighted areas where money might need to be spent and provided guidance on questions for my solicitor - just what I needed. Overall, the survey enabled me to re-assess my offer and in this respect was invaluable. Thank you for a friendly and professional service.

100% choose this company. As first time buyers we had a mortgage valuation which said the house was fine. The Arnold & Baldwin survey found over £30,000 of problems. Holes in the roof with daylight visible, damp, woodworm, broken sash windows and poor electrics. This company helped us renegotiate and save a fortune.


Arnold & Baldwin came recommended and I’ve got to say they were brilliant - not just in identifying issues with the property I was looking at but in the way they kept me informed and up to date (ie picking up the phone instead of just posting / emailing communications with you). After dealing with estate agents for so long, it’s nice to have someone who is genuinely on your side.

From my initial interaction with the firm I found them to be prompt, courteous and helpful. I received a detailed Homebuyers report within a week of instructing and was given the opportunity to talk it through with the attending surveyour. Overall excellent service all round, would certainly recommend this firm.
