Of course the agents and companies will run ads featuring your house, but not for the reasons you expect.

You see, the main job of advertising is not to sell your house directly. Advertising creates phone calls and some of those callers become clients of the agents answering the calls. This builds up a pool of homebuyers looking for property in general, all represented by selling agents. Multiply this by all the agents and companies who also advertise homes, and there is a large pool of homebuyers in the market at any given time – all of whom are represented by selling agents.

The agents representing those homebuyers know about your home because it is listed in the Multiple Listing Service, has been on office and broker preview, and because your agent may have also sent flyers to all the local real estate offices.

The agents match up their clients with available homes, one of which may be yours. Then they show the homes to their clients, who eventually make an offer on one.  That is how your house gets sold. Ads create a pool of clients, one of which buys your home. Ads do not usually sell your house directly.
