The Scottish market for homes worth over £1 million witnessed an “unprecedented level of activity” in 2021, according to Rettie, with a record 419 such homes sold.
The previous high was 289 seen in the 2007 market boom.
Edinburgh accounted for two-thirds of such sales.
Rettie said this level of activity was almost 50% higher than the already buoyant 2020 market and saw the total value of £1m+ house sales in Scotland jump from just over £400 million in 2020 to £583 million in 2021.
Rettie MD Simon Rettie said: ““The surge in £1m plus house sales over 2021 has been a notable feature of the post-lockdown housing market.
“Such sales are now well ahead of their previous peaks and nearly 50% ahead of 2020 levels.
“One response to the post-lockdown world has been people’s willingness to consider more rural areas and accessible towns, and the sharp rise in demand for this type of living has caused prices to surge in some of these areas, pushing the most desirable properties over the £1m mark.
“This is clearly seen in parts of East Lothian as well as north of Stirling and east of Loch Lomond.
“However, Edinburgh remains at the heart of the Scottish £1m market, accounting for two-thirds of such sales.
“Nevertheless, here too there has been a greater diversity of such sales, with more pushing out to locations such as Colinton and Trinity, outside previous core prime areas.”
Counting only homes registering values over £1 million, and excluding the likes of farms, estates, land or commercial buildings, 2021 saw a staggering jump in sales at the top of the market.
Rettie said there were 419 registered home sales over £1 million, almost 50% higher than 2020, which itself was the highest recorded figure since the 2007 market boom.
In terms of value, the average £1m+ house sale in 2021 was £1,392,000, down slightly from values of over £1.4 million in the preceding three years.
This has been due to the volume of homes now breaking through the £1 million threshold.
The number of homes selling just £50,000 over the £1 million threshold increase by 85% from 2020 to 2021, rising from 12% of the £1m+ market to 15%.
