HOME buyers are facing bills for thousands of pounds by failing to have a sufficient survey of their new property before moving in.

A survey from the Royal Institution of Chartered Surveyors found that a quarter of buyers who only had a mortgage valuation report had to make unplanned building works to their property after purchase.

On average, the bill for these works, such as damp proofing or repairing a roof, came to £1,818 – but the cost can be much higher.

Home surveys help buyers make informed decisions on whether to go ahead with buying a property, before legally committing themselves. Despite their importance, many buyers remain confused about surveys.

A mortgage valuation report is often wrongly assumed to be a building survey. Actually, it is purely an indication of the property’s value for loan purposes, prepared for the lender, not the purchaser.

Most importantly, it won’t uncover any potential problems.

Even if you are paying for a mortgage valuation report, RICS still recommends you arrange a survey with your own surveyor.

There are two options available; an RICS Homebuyer Report, which provides an inspection and report on the property’s condition, plus a valuation.

A building survey is more detailed, and is often the best option, particularly if the property is in a bad state of repair, has been significantly altered, or if you are planning a major conversion or renovation.

David Dalby, RICS residential director, commented: “In difficult economic times it makes sense to ensure you are getting the best possible value when purchasing a property.

“No one wants to find a nasty surprise down the line, or pay over the odds for a property that needs lots of work.

“A survey not only gives you a price valuation, but also a detailed report of the state of the property. Armed with this information you are in a much stronger position to decide whether to proceed with the purchase, or negotiate a better deal.”
