So, just so I am clear, your thought is that if you can find a Realtor who will work for below market compensation, then you will net the most (or lose the least) when you sell, is that correct?
Think about it.
A Realtor that will agree to work at a discount...off the bat, as a preliminary point of asking "why you should hire me?" well, you might want to interview a couple of Realtors and compare.
Just looking at the link below, your market appears to be declining. So, just my humble opinion, but what if you are wrong with your assessment of market value. Most owners think their homes are worth more than they are, and in a declining market, the goes double. BTW, an appraisal is not the same as a market analysis (it depends on the purpose of the appraisal. If the market is headed down, which it appears to be, then an appraisal , which is based on closed sales, lags the market conditions and overstates the value).
