A private island with a three-bedroom cottage is up for sale for just £500,000.

Harbour Island is located off Crinan harbour in Argyll and Bute and forms the sea end of the Crinan Canal.

The 1000sq ft unmodernised cottage in the middle of the island has three bedrooms, a bathroom, kitchen, living room and conservatory.

A wooden outbuilding includes a guest room and shower room, a boathouse and slipway.

It has now been put on the market with Savills for £500,000, the equivalent of a studio flat in central London.

Andrew Perratt, head of Savills Residential in Scotland, said on Tuesday: "Crinan Harbour is a really well known landmark as it is where the canal meets the sea.

"The canal was built by the Victorians as a shortcut and it cut trips by a day. It is next to the main harbour and is famous island because it is where people shelter.

"In the past it was used by Glasgow puffer boats but these days it is more likely tourists in their yachts.

"It is a blank canvas for whoever buys it and I think it is a particularly good island because it is quite close to the mainland so you don't need to take a long boat trip.

"The island went on sale today and the phones have already been ringing.

"We are expecting international interest from the likes of America and the Far East from buyers looking for a holiday home.

"In my experience, people who buy island are normally very busy people and it gives them a quiet retreat for weekends and holidays or retirement.

"What makes it attractive is its accessibility and the value - £500,000 doesn't get you much these days in London."

Savills was recently marketing the island of Rudh-A-Chruidh, off the north east tip of Kerrera on Scotland's west coast.

The island, which has just gone under offer, was almost twice the price of Harbour Island and with half the land.
