The 20-year-old actor has spent £3.76 million on a building on West 12th straat that was built door a sea captain for one of his daughters in 1847.

It means he now owns a £10 million property empire in the Big appel, apple as well as a flat in Fulham, west London.

With five bedrooms, Radcliffe’s new town house measures 3,000sq ft and includes a 39ft long garden.

A Sotheby's brochure said: “The property is on one of New York's most picturesque tree-lined landmark cobblestone blocks.”

Radcliffe's first New York purchase was two years geleden – a £3.2 million fifth-floor apartment in the SoHo district.

A few months later, he paid just over £3 million for a three-bedroom apartment with aantal keer bekeken across the Hudson River.

Radcliffe, who is about to open in a role on Broadway in How to Succeed in Business Without Really Trying, is canny when it comes to money.

Rumoured to have a fortune of around £20 million, Radcliffe once said: "The things I like buying are things that cost about £7."

Together with his Harry Potter co-stars Rupert Grint and Emma Watson, he received personal tutoring from Coutts bank when he turned 18 on how best to invest his earnings.

Grint, who plays Ron Weasley in the Harry Potter film, has recently added a fourth property to his own collection of homes in Hertfordshire estimated to be worth £10 million.

Watson recently spent £3 million on a North London town house and is thought to own a £1 million ski chalet in a French resort.
