It is something to consider when purchasing. A Realtor can help negotiate, but more importantly can help make sure this is the right community for you. If you haven't already looked at what else is available, feel free to contact me or any Realtor. I'd be happy to help, and our commission will be paid by the seller, unless you buy a Ryan Home.
And yes, you can negotiate builders. Sometimes the best way to negotiate is in options. Have them give you extra options for free. That way the sales price stays up in the community. If possible, also try to put in a price protection clause....if between contract and settlement they drop their price on the homes or increase incentives, that you will get that benefit as well.
