My mum has been looking for a house for ages and saw one on Rightmove she liked today. It's being marketed by an EA. Anyway, one of her friends lives fairly near the house ( although they don't know them) and said he'd go around to knock on the door to say she's interested. They owners have arranged a private viewing for next week.
Personally, it's not something I'd do or have done myself but wondered if there were any drawbacks/ things to be aware of doing this?
