I see a poster (?liz's daughter) posted on Manxforums and got referred to en.wikipedia.org/wiki/Kate%27s_Cottage - "The typical nineteenth century Isle of Man stone-walled cottage was occupied by the Mountain Shepherd Cecil Rhodes Tate and Gladys Tate and a BBC commentator mistakenly referred to "Tate's Cottage" as Kate's Cottage." quotes ref to Motocourse History of the Isle of Man Tourist Trophy Races 1907-1989 by Nick Harris 1990(1st Edition) Hazelton Publishing ISBN 0-905138-71-6.
Judging from its position I suspect it was only occupied during summer months
