We sold our small farm in Scotland in 2017 and did not get a home report done as the farm is classed as a commercial property. We had about 47 acres & had been running a small livestock business -selling beef, cattle, a few sheep & hay. VAT registered etc...
Our solicitor was experienced in agricultural property sales and was happy that we didn't need the home report to sell the farm. If you're serious about this property I would suggest getting confirmation from a good local solicitor who knows about agricultural sales.
Our buyer got a land agent to do a survey - to value the house, farm buildings and the land. He used Galbraith.
Hope this helps
