If that is not your real objective, then you have many choices. The best one for you really depends on the METHOD you may select to get your home sold.
You may choose:
One guy asked about selling a house via raffle tickets.
The method you choose dictates the audience that will be attracted and therefore the venue through which your ad must appear.
Or you can just buy the biggest sign you can find, put an ad on Craigslist and stick out a couple dozens bandit signs.
