Property expert Stuart Douglas has given an insight into why many people's homes don't sell. Stuart, 48, is best known for presenting the hit Channel 4 shows Worst House on the Street and Can't Sell, Must Sell alongside his sister Scarlette.

The siblings are currently in the middle of filming the next series of Can't Sell, Must Sell, with Stuart giving us an insight into what fans can expect from one of the episodes - and the common mistake people make when it comes to selling their property.

He exclusively told the Daily Express: "We are there because these houses cannot be sold and we are there to work out why. In this particular episode, it was clear to see why. Every cupboard, every drawer, every room had things in it.

"You couldn't really move. She would work from home. Her home, in essence, was her storage unit. It was crazy. We had to declutter and make the home appealing to the general public.

"When you critique someone's property, it's almost like an attack on their personality. We don't want to do that. If you are staying and you are going to live there yourself, by all means, have it how you want because it's your home."

Stuart revealed the simple tasks that homeowners can do that will likely increase the chance of selling a property.

He continued: "If you're trying to sell it, you need to depersonalise and do simple things. A general clean and a declutter go a long way. That's what we had to do. It was a hard task, but somehow we managed to pull it off."

"It's very interesting what you see behind closed doors. You know how you live yourself but it's very interesting to see how other people live. I find it surprising that they don't know why their house isn't selling when we come into the property and it's clear to see why.

"It's just trying to make sure they understand the reasons why without being offended, because we don't want to offend anyone, we just want to help them sell their house."

Stuart also highlighted the differences between homeowners on Worst House on the Street compared to Can't Sell, Must Sell.

He explained that buyers know they've purchased a property that needs significant improvement when appearing on Worst House on the Street, so they're more open to advice and changes.

Whereas, on Can't Sell, Must Sell, homeowners are emotionally attached to their homes and like them as they are, making them more resistant to criticism and change, even when improvements are clearly needed.

Stuart observed: "With Worst House on the Street, because they have brought their house wanting to make it the nicer house on the street, they're more willing to listen.

"They know that they've brought something that needs a lot of work or something that isn't that nice on the eye or not very desirable. But they've brought in a good area. They literally just need our help. There's no way near as much kickback because they make their house great."

He added: "On the other hand, on Can't Sell, Must Sell, that is their pride and joy. The house is exactly how the owners want their house. You have to tread carefully.

"When we go there, and there are things that are blatantly obvious that need to be changed, those are things that the owner genuinely likes and wants to keep.

"You do get a bit of an obstacle. They don't like the change. It's the change that's tough because people have been in there a long period of time. They want their house as it is, they like the way they are able to live in it, so it's a lot of upheaval and change and that doesn't always go down well."

Stuart and Scarlette recently concluded their latest renovation project on a house in Bournemouth.

They launched Keys or Coffee in December last year and began renovating a home - designed by social media - which is now up for grabs. And the best part, you only need to spend £3 - the price of an average coffee.

Keys and Coffee was launched in the hopes of making home ownership "accessible, meaningful and exciting".

Members of the public can enter the draw to win the property here.

There are also bundles available, with a trip to Rio for two with a coffee tour and a separate prize of £5,000 up for grabs.

The winner of the property, and the other prizes, will be announced on April 19 at the Ideal Home Show.
