If this business was as easy as it sounds, everyone would be doing it. Most of the time, selling real estate requires skill. I have not seen your listing, so I do not know now it is being marketed.
Just taking your statements at face value, every good REALTOR does what you just said. It is the WAY that these activities are executed that makes the difference.
For example, no offense to JR and Michael, but suggestions like those you suggested may not be in David's best interest. Sticking a sign in the yard that says "buyt this will $500 down" violates a number of principles and probably lending regulations in various states. Besides, you're not selling a car, you're trying to attract the largest number of qualified buyers.
Also, if David was selling his property without representation then handing out flyers at real estate offices is not going to do anyone any good either, except the people that sell you the paper and the toner!
Without rehashing the numerous posts regarding marketing a home, the basic principles of marketing apply:
1. How many comparable homes are on the market?
2. Have you seen any of them and how they are being marketed?
3. Why should a buyer purchase yours rather than any of the other homes?
Answer that question and you are in business. If all the homes are being marketed the same way, and they are all comparables, then you are understanding that to make a home marketable.it takes strategy.
