Hi Neil, please see my opinion below, i am not saying i am right and this is the only way to do it, but i know it works for many of my clients!!
Is the answer to the question not dependant on what you are looking to achieve from the canvassing?
What sort of return are you looking to get? Tout/canvass letters are going to be sent to clients who have recently placed a property on the market with another agent, who is likely to have tied them into a contract and be actively marketing and generating viewings! Whilst you may know that the agent with the instruction is useless and you could do a far better job, it’s unlikely that the vendor will be unhappy at the point you (and i imagine every other local agent) first tout the property!
Is it not better to write saying you have noticed they are moving but have not registered with your company and in order to provide your clients with a fantastic service, you go to great lengths to ensure you have every buyer looking locally registered, hence your letter, this gets them to register which provides you with contact details which in my opinion, is job done, if your staff are on the ball then a rapport is built and that vendor can be spoken to every week without thinking you are just trying to get the instruction.
Is the most important question-Why were you not called out initially?
Leaflets do work but only as brand awareness, if you were to drop 20,000 flyers, only about 7% of them people would be looking to move at the point you drop them, leaflets need to be regular and give a reason to be kept or remembered, do not tell people how great you are as it will be chucked out, give them something to interact with, it does not need to be associated with property, puzzle them or make the flyer appeal to kids, then it will be kept or remembered, if this is regular, then when they come to sell, you will be the first name they think about??
