While driving through newer additions searching new construction, having a knowledgeable Realtor at your side is important. will be your guide when navigating the myriad of new homes today to locate one that's right for your family.
In real estate, you can always negotiate. However, with new construction, it depends on the builder and how long the home has been available. Developers in new additions like to keep prices near their asking point because buyers already in the area expect new construction to be comparably priced to what they already purchased. (You'll appreciate that same courtesy if there are undeveloped lots near the home you eventually purchase!) But, depending on how far along the project is and what the market is doing at that point in time, a builder will often allow a few concessions.
For example, if the home is pretty much move-in ready, you have little to no negotiating powers. But if the home has been sitting fully furnished, like a show or model home, and there haven't been many offers - then the builder might be willing to work with you. The longer the home has been on the market, the more the builder has invested.
In situations where a builder won't budge, ask for assistance in other areas. Ask for help with the closing costs, or more amenities, like an allowance for window treatments, a garage door opener, a fence or landscaping, or an extended home warranty. Or take the contrary route. If a home is nearing completion, you can often save money by passing on suggested upgrades from the builder and installing things yourself.
While you should always negotiate a home warranty so problems can be fixed, it's also imperative you get a home inspection before closing. Inevitable problems can be repaired (by the builder) before you move in and larger problems identified before it's too late. Since an inspection is relatively inexpensive, some new home buyers get an inspection after being in the home for 10 or 11 months - that way, the builder can make the repairs before a 1 year warranty expires.
