If you have clients that want to buy a home take them on a thorough tour and write down the addresses of every home they liked. Then, get the actual names of the owners of the homes. This is very easy. You can go to a list company or look up the tax records online.
The reason you want the real name is because if you have anything other than the actual owners names on the letter it looks like it was spit out by a computer and not a real person.
The more ‘real’ and personalized the letter is the better your chances are of getting a response.
