Just because it cost $7mm to build does not mean it is worth $7mm today. Get some comps of other homes in the area to see what they have sold for. Are there any comparable homes in the same neighborhood?
I would certainly NOT settle for splitting commissions if you secure the buyer. You need to get an option, then do the HBS. You should get everything over the strike price. The agent should get 2-3% of the option price – which is paid by the seller.
You need to do aggressive marketing – and it has to explain what are the benefits of that area and that house vs other choices in that price range. *if you can’t answer that, don’t do the deal)
