Ah I had a CL deal fall apart (my fault) on a TSPP yesterday. I asked for more photos (since there was ONE in the ad from 20 feet away). Seller got back to me right away (AM) and stated pics to follow in a bit. Whilst waiting for pics I guess someone else already negotiated the price down to $3200 and was going to pick it up that night. Seller has been really nice, I guess guy dropped off a check and is waiting for it to clear to sell.
Morale of story don't wait for more photos and deal on price beforehand I suppose... I didn't want any bad juju or spoil someones sweet deal so I didn't bother with trying to give him $100-$200 extra on price.
Hope it went to someone who wont flip it.
