If you become seriously interested, the advertised price will rise as the developer tries to sell you the extras. Buying extras lets you semi-custom design your home. But ask yourself what you really need and how much it will cost. First Be practical. A fireplace and hot tub are not.
Some developers are less ethical in pricing extras than others.
Negotiate Ask for one free extra for every two you buy. For example, if you pay top dollar for good carpets, tile and kitchen cabinets, ask the developer to throw in a better stove at no charge. And don't be afraid to ask for the right to buy and install extras on your own. Your best bet is to buy from a developer who includes a new house warranty from an independent insurance company. Typically, they cover workmanship and materials for one year, plumbing, electrical, heating and air conditioning systems for two years and major structural defects for ten years.
