House prices may be stalling, but home owners in one Perthshire street might have less to worry about than most - after it was named the most expensive in Scotland.

Houses in Caledonian Crescent, in Auchterarder, have an average value of £1.8m, according to the Scottish Property Rich List which was published yesterday.

The crescent narrowly beat Balmoral Court, another street in the town, into second place. Average home values stand at just over £1.5m in Balmoral Court.

The rich list highlights the hot spots across Scotland and is published by Zoopla.co.uk, the property valuation website.

Auchterarder is home to the world-famous Gleneagles Hotel and Golf Course and the legendary former world snooker champion Stephen Hendry, so perhaps it is no surprise to see that the two most expensive streets in which to buy a property are located there.

Scotland's capital city has reaped the rewards of the property boom over the last few years and Edinburgh dominates the remainder of the list of the top 20 highest-value streets with 12 around the capital making the grade.

These include Wester Coates Avenue, which came in at third place with property values averaging £1.4m, and Easter Belmont Road, where properties are priced at just under £1.3m.

Edinburgh now has 213 streets where house prices currently stand at more than £500,000, according to Zoopla. This compares to just 109 such streets in Scotland's largest city, Glasgow.

Just squeezing into the top 10 most expensive streets in which to live is Main Street in St Andrews, where homes average just over £1m. But while these properties in Scotland are doing well, Britain's most costly streets are still, unsurprisingly, all in London. The most expensive was named as Kensington Palace Gardens - Princess Diana's old street.

The average house price there is £41.4m and current residents include steel tycoon Lakshmi Mittal, who paid £117m for his home.

The street, dubbed Billionaire's Row, is so exclusive that prices are £34m greater than its closest rival, Compton Avenue in Hampstead, North London.

When it comes to the most expensive areas to live in Scotland, the rural parish of Humbie, in East Lothian, takes the top spot with an average value of £390,105. This is closely followed by Milltimber, a suburb on the outskirts of Aberdeen, where properties average out at £368,818.

The suburb is known to be home to the more wealthy residents of Aberdeen, many of whom are foreign oil industry employees.

A number of suburbs of Edinburgh also have a strong presence in the top 20 areas. These include the Morningside area of the capital, which comes in at number three with an average value of £327,716. The Highland village of Plockton, meanwhile, is at number five with an average value of £318,323.

At the other end of the spectrum, homes in parts of the east end of Glasgow cost an average of £63,810, while the islands of the Outer Hebrides have average property prices as low as £73,296. Wick in Caithness, Stevenston in Ayrshire and Lochgelly in Fife are also listed among the 20 lowest value areas.

Alex Chesterman, chief executive officer of Zoopla.co.uk, said: "The Property Rich List provides the most in-depth guide to property values in Scotland, as well as the rest of the UK, highlighting where's hot and where's not and is updated continuously, allowing us to report on movements and trends."

The report comes amid fears that the credit crunch is beginning to affect the property market in Scotland, with the number of transactions and new mortgage approvals falling.
