Accurate pricing requires detailed specifications and input from suppliers and trade contractors. Done properly, the process takes days to weeks. Buyers who do not understand the complexity of this process and the importance of clearly written, detailed specifications sometimes compare floor plans based on cost per square foot. For instance, buyers comparing two homes that each include 4 bathrooms and 4 baths might find one is built for $81 a square foot and the other for $92. However, the apparently more expensive home might include a level of quality, features, and materials justifying the higher cost—items the buyers truly want. Study the details of materials and features included in the square footage you are buying and select your home and builder based on comprehensive information.
