Selling a house is a frustrating, time-consuming venture at the best of times—so imagine trying to sell an entire village.

Or, as in the case of Spanish-based realtor Mark Adkinson of Galician Country Homes, up to 400 villages.

“It takes a year just to get the paperwork together,” Adkinson, 67, told Fortune from his office in Lugo, Spain, in the far northwest of the country. “We’re currently working on a village where 24 different people have plots of land. How do you get 24 people into agreement [to sell]?”
