When to sell a new construction home

[Mark Caragio]

I am starting a project to subdivide a property I own--in the heart of Silicon Valley and in the CUSD--and plan to sell one of the two homes as soon as possible.  At what point should I list it?  I'd like to pay off the construction loan asap, so I was hoping to list it shortly after framing starts, sometime late this Spring.  I have been advised, however, to wait until it is complete.

And, along this line, is it advised to pay the 2.5% - 3% to a listing agent, with it being a brand new home and (assuming it remains) a hot real estate market.  Three much less impressive, nearby properties sold in less than a week for over asking, and currently there are only two other 4+ BR homes listed within a 2 mi. radius.

Finally, what should I offer the buyer's agent in the listing, if I FSBO it?
