What it's like trying to sell the flat that belonged to Britain's most famous serial killer

Reuben John works for the Paul Simon estate agent and his job is to sell a beautiful one-double bedroom, top floor flat with its own private balcony in one of London’s most sought after areas, Muswell Hill. The flat is being offered at the bargain price of £300,000 ($US460,000).

London has one of the hottest property markets on the planet right now, and this seems like an incredible deal. It is easily worth £375,000 or more, in any other location.

There is just one problem …

… But first, here’s a look at the flat! It looks incredible, right?

Look at all this space!

Well, this apartment isn’t for everyone.

It happens to be where serial killer Dennis Nilsen lured home between nine and 12 young, homeless, gay men and prostitutes, with the promise of food or alcohol, and murdered them.

Nilsen moved intoFlat 23D, Cranley Gardens in North London in October 1981 and was arrested 16 months later when the drains became clogged with bits of rotting corpses. He used to chop up the body parts and flush them down the toilet. This is what it looked like when Nilsen lived there:

It has been over 30 years since those gruesome events but it looks like people still cannot seepast Nilsen’s legacy tothe incredible real estate deal that’s now on offer in lovely, leafy North London.

Estate Agents Paul Simon are upfront about the flat’s history. It’s website boldly says:

Reuben John, the Paul Simon agent for the property, tells Business Insider that “when we initially marketed the property, we were inundated with enquires and booked an average of eight viewings a week. We are now only achieving minimum interest, say one or two enquiries a week.”

The Cranley Gardens flat was sold at auction for £250,000 ($US384,000) in August 2013 to a developer who, according to a Business Insider source, wanted to renovate the property and make a bumper profit. They believed it was going for nearly £100,000 ($US153,673) less than comparable properties in the area at the time.

The owner did a great job. Look at this renovation:

It looks absolutely nothing like the time Nilsen lived there:

However, the owner has struggled to offload the property since last year.

The flat may have a past but John, who said he would happily buy the flat himself if he had the budget and was looking to buy in the area, highlighted how awesome the flat actually is.

If the property’s history wasn’t an issue for people this property would be going for around £375,000 ($US576,680). It would also have a return of 5% for buy-to-let investors who could rent it out.

It even has an awesome private balcony, which is rare in London flats at this price. One prospective buyer remarked to John that the property had “killer views”:

But, unfortunately, John said people are only offering “ridiculously low” offers at the moment but remains optimistic: “The right buyer will pop their head up, we hope!”

It can’t help that even some of his co-workers won’t even go into the property to show people around.

“One of my religious workers said he felt the presence of Jins (ghosts) and refused to do viewings,” said John to Business Insider.

Crucial question: is the property haunted?

“Being a person of logic and science, I don’t think it is. Saying that, just because you can’t see it, doesn’t mean it’s not there. So I’m sitting on the fence with that one, like any good estate agent,” he said.
