One of the biggest mistakes when choosing the right floor plan is that you forget to picture your own family cooking in the kitchen or you don't take into consideration how your bad back may not like going up 3 flights of stairs throughout the day. Assess your lifestyle before choosing a floor plan. Do you like a single story or multistory home? Do you prefer an open floor plan or are individual rooms with partitions better? Determine what you have become accustomed to in a comfortable home.
While you can change your floor plan in the future, remember you can't change the location. With this in mind, don't make the mistake of falling in love with a floor plan and forgetting about the property and surroundings of your home. If you fall in love with the layout of a master bedroom in floor plan, but don't like how it looks out over the street in the model home – chances are your home in your location will have a totally different aesthetic, view and therefore feel different. Remember when choosing a floor plan; ensure the interiors will fit with your location.
