Currently there are three houses and one combined shop and tea room for sale on the open market. Am not sure, but that may be a record for Berneray at any one time.
Details and links of these available on the Berneray website (one of my hobbies is messing around with this website):
The houses are offers over 150K, 110K and 30K. As you may expect, the lower the price, the more work that is required on the house. The 30K one is an ambitious property developers dream. Also - if you aren't used to the Scottish system, note the "offers over"; houses are usually sold on a "sealed bid" auction basis.
Still; with four properties for sale, an ex-resident of Berneray returning to get married today in nearby Lochmaddy (reception in the hall in Berneray), and the sheep dog trials on the machair this monday coming, there's no shortage of gossip, speculation and chatter around the island at the moment.
