In summary- agreed private sale on house early July. House never went formally on the market although EA did show one couple round but there were no photos, no Rightmove presence, nothing on EA website.
In the past week I have had 4 postcard things in the post from removals firms to my address so not random distribution. Is it possible that someone has passed on information to removal firms about sold houses? It just seems weird that its happened this week!! They are all local firms - I'm tempted to ring one up and ask them why they sent it!!
