When scoping out newer neighborhoods looking for new construction, having a knowledgeable Realtor at your side can be the difference between a good home buying experience and a bad one. will be your guide when navigating the myriad of new homes today to find one that's a match for your family.
In real estate, you can always negotiate. However, with new construction, it depends on the developer and how long the home has been on the market. Developers in new additions don't like taking lower than their asking price 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 current market conditions, builders have been known to allow a few concessions.
Consider a home has been on the market a long time and the builder has a lot sunk into it, then you have some room. The same goes for show or model homes that have been sitting for a while. However, if a home was just completed, it's unlikely you'll get a deal.
You can always ask for assistance in other ways when purchasing new construction. For example, closing costs are one way for you to save without lowering the price of the house. The same goes for amenities - ask for things an allowance for window treatments, a garage door opener, a sprinkler system or landscaping, or an extended home warranty. That can go the other way around, too. If upgrades are already in the plan, see if you can get the builder to remove them - you might be able to install them later yourself at a savings anyway.
While you should always negotiate a home warranty so problems can be fixed, get a home inspection before your purchase regardless. Inevitable problems can be repaired (by the builder) before you move in and larger issues identified before they become your problem. 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.
