Demand for sporting estates in the Highlands and Islands remained "robust" during recession-hit 2010, according to sales agent CKD Galbraith.
During the year, the firm was involved in the purchases of Leys Castle Estate in Inverness and Garanahyne Estate on Lewis.
CKD Galbraith partner John Bound said the market was not recession-proof.
But he added that it had not suffered in the same way as the sales of residential properties.
Mr Bound said buyers saw sporting estates as a long-term investment which provided them with enjoyment, but also supported fragile rural communities.
He said: "Our assessment of the market is that it has been relatively stable, not recession proof by any means but estates are not subject to quite the same price sensitivity that is experienced in the residential property market.
"You seldom see an estate being marketed at a knock down price and there is still a lot of money at the top end of the market."
The firm said north estates were rich with deer, grouse and salmon.
Earlier this month, Scottish surveyors reported a slowing of the housing market with prices slipping even further.
The Royal Institution of Chartered Surveyors (RICS) said 20% more members reported that prices fell rather than rose in November.
