Property prices have soared at a record pace as desperate buyers have jostled for the limited number of new homes on the market.

Yet even though demand is high, sellers are not guaranteed to turn a profit from their bricks and mortar. From interior faux paus to dubious paperwork, sellers could unintentionally shave tens of thousands of pounds from their property price, or even kill a sale altogether. 

Telegraph Money spoke to property experts about the most common ways you could accidentally damage your house price.

1. Too much ‘you’

Robin Gould, of buying agency Prime Purchase, warned an over-personalised property was a big deterrent for potential buyers. 

“I viewed a property on behalf of a client which had an outdoor swimming pool with a tiled mural of the owner on the bottom. Why any buyer would want a lasting reminder of the previous owner is beyond me,” he said. 

“Unsurprisingly, the client didn’t buy it. But if the vendor did eventually find a buyer, one of the first jobs would have been to retile the pool, which could easily have cost hundreds, if not thousands of pounds.”

A survey of more than 2,000 adults by GoCompare Home Insurance found one in ten would be put off buying a home with over-the-top décor or carpets. An untidy house was a red flag for 18pc of respondents. 

Sarah Cull of Strutt & Parker, an estate agency, said being too bold with colour and styles in rooms which were expensive to change, such as kitchens and bathrooms, was especially off putting. 

She added: “Buyers often loathe to undo something which has recently been finished, but not to their tastes. Some flare in styling is fine and features like curtains and paint can be easily changed, but bigger, bolder fixtures can start causing issues.” 

2. Overdeveloping your home 

As the saying goes, less is more. Overdeveloping a house and making it too big for its plot can knock tens of thousands of pounds from its price tag, according to Ms Cull. 

“Owners have the best intentions when extending or adding to their house, but if it doesn’t balance with the garden space then it can really devalue a home,” Ms Cull said.

“It really does depend on the price of the property, but say a house was on the market for between £700,000 and £800,000 then overdevelopment is capable of reducing the price by £50,000.” 

3. Suspect paperwork

With so much time spent indoors since the pandemic hit, many owners turned their hand to home improvements. But planning and consent rules can be complex and it is not always clear what changes need permission. This, warned Ms Cull, has often led to issues when selling.

“Sellers not getting the necessary consents or building regulations for works in both listed and unlisted properties can really damage the price, or even kill the deal altogether,” she said. “On top of this, a serious breach of consent can involve hefty fines.”

In some lucky cases retrospective permission, awarded after works are completed, can be granted, but anyone buying the property risks instead being ordered by the council to revert the property back to its original state.
