I’m sorry, I really don’t want to rain so your parade, but post cards seem like a poor method to find a seller. It may work, kinda like bandit signs, they must work, if not why are so many using them? In my opinion all these do is lesson your brand. I get a couple cards every week offering to buy my house from some strange city that I have never been to. From the receiver of this card it appears to be some kind of scam.
Do you want to buy any/every house in the city, pay pennies on the dollar, paint it and sell it for a 30%-40% profit? To me that is what that is what post card is saying, trying to find someone in desperation, for a quick sale.
May I suggest you “drive/walk fo dollars. Find the house which has potential as a buy and hold investment, find the owner and gently make contact stating that you are interested in buying a home in that neighborhood and if he/she has ever considered selling could we possibly meet for coffee and speak of the possibilities.
Yes, it is slower. Can’t do a bunch a month. But it gets results.
