When you sell the house, offer people the reasons for the success (agent or not) and the "how to's".
Some people do really well on their own- the curiousity of potential sellers can benefit from the perspective of a successful for-sale-by-owner experience. I might even steal some of your ideas.
The other aspect is that there are a lot of other vehicles for marketing your home, some of which are only available through a realtor. Unless your local market is robust and homes are selling at a brisk pace, you will likely benefit from a realtor's marketing experience and capabilities.
A realtor also has access to market information that is comprehensive and reliable that can help to assure that your home is properly positioned in the market. An overpriced home may get inquires, but you need a ready, willing and able buyer with an offer to actually sell your home. If the home is not priced correctly, it will either sell quickly for less than the market value, or it will stay on the market for a long time and finally may sell for less than it would have if priced correctly in the beginning. That is where a experience realtor brings value to the transaction.
Good luck with selling your home, regardless or whether you do it by owner or through a realtor.
If you can do it, then do it. Most people hire a lawyer when they get in a lawsuit, most people hire a mechanic when their car breaks down, most people hire a doctor when they are sick, most peple hire an accountant to do their taxes....AND most people hire a realtor when they are buying or selling, Thier service is really a true value wiether you want to believe it or not. If you think you can sell it on craigs list and save some bucks, every realtor on Trulia wuld say go for it!! Unfourntuately it's a complicated process...... They will represent you and get it done easier, trust me! And I dont know one damn realtor on here! No ties, I'm a loan officer
If so, I would have sold many all my properties thousands of times over.
My commission is earned for doing and knowing much more than Craiglists. Craigslist is only a very tiny, little part of what I do for my clients..
