Home buying: you pay $200k for a house. Add a few thousand more for closing costs, thousands more for paint and new flooring and deferred maintenance. Now you're into it for $220k. Conservatively. Six months, a year down the road, you have to sell. Probably just to get what you paid for the house out of it, the sales price is $232k, factoring in the realtor commission. 
What's the solution? Give realtors 2%? Sell it yourself, with attorney fees? Take a loss?
