I don't mean try and cut out the agent, but merely to tell them why I want the house in case it sways their opinion. I've found out the house I'm buying 130 Mike's away is owned by landlords living about a Mike from the flat I've just sold (I've moved in temporarily with my partner 30 miles away). I could probably track them down via Facebook or ask friends to drop a letter through the door.
Is that a normal thing to do or do I have to hope that the agent would pass on my letter?
