I'll respectfully disagree with Ms. Linda Lorenzo below. You can obtain mass media even with the smallest of brokerages. The average Realtor knows nothing about search engine optimization or online marketing. In our market, our board provides a syndication service so when I list a house it feeds to hundreds of places. But I also blog the listings so it creates presence as well. If you're relying on the mass media places, forget it. Long tail online marketing strategy is more effective and I'd be happy to back that up with references.
Less than 1% of homes sell via open house. The fact is, unless the buyer is not committed, or a pain in the xss, then they will choose to go through a Realtor since the service is paid for by the seller.
Case in point..... I hold open houses on occasion because the seller believes I'm working for him. I said on occasion, right? "Here's what I get: We just started looking and haven't even decided if we want to move. We've been looking in this neighborhood since they started building 6 years ago. I'm looking for my daughter but I don't know what she wants. I don't trust Realtors, they'll all just trying to get my money. (My response: Really? I'd be happy to have my pastor call you with a referral about my services to him. His response: No because he's probably lying too. Trust me, this is not the person you want buying your house if you have a choice of buyers.)
I'm sure you've got at least $100,000 tied into this house. Why risk such a big investment? You'll have more risk for a law suit, waste hundreds of hours, get less since you will not know what your house is really worth resulting in low ball offers and may take one due to frustration. Not staging it right will cost you at least 6% according to NAR surveys.
Bite the bullet and get a great Realtor. I know some in your market.
