Is this a new development
Is this a proposed house or being built
How far along are the houses if they are being built
Whether the seller will accept a lower offer depends on a lot. If this is new construction, then the builder will figure out what it will cost to build the proposed house and then list it at that price. If the builder hasn't begun building it, then they usually don't accept lower offers because there is nothing there yet. If they are going to take a lower offer, then they are probably going to cut something out to bring the price down to what the offer is. If the house is already built then they may accept a lower offer to get the house off their books. Usually builders construction loans aren't due until the house is completed so they may come down a little in price to get it sold. Hope this helps.
