Most just throw it on MLS and let the market run its course. The same effort goes into selling a 200 grand house that goes into selling a 400 grand house. I would put my negotiating skills up against any realtor, in fact I negotiated a better deal than my last realtor when he was ready to take the sellers offer without a counter.
Unfortunately, you're probably not far off, especially the way the market has been in recent years - some will just throw a million-dollar listing on MLS and call it a day. I try to put forth the same effort on all transactions, if for no other reason than a $40k investment condo deal done professionally may result in millions of dollars of business from both the initial client and referrals. Conversely, one of the transactions that took the most of my time - about 80 hours - netted me all of $600 in commission, no further business (despite promises otherwise), and no known referrals (despite promises otherwise). I just try to do the best on every transaction.
I know a good agent in Austin, she sold my mother's house in RR a few years ago - absolutely professional, mostly does RELO work which requires it. PM me if you'd like her info.
