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.
If you're shopping around for homes one of the best ways to experience the floor plan of a home before you buy it is to walk through the developer's model homes before hand. One of the easiest mistakes is to get sold on the upgrades that a home stager and contractors have upsold the model on! Try and strip away the gorgeous finishes, the upgraded carpet, color coordinated wallpaper and drapery and focus on the layout and flow of the rooms. This will help you make an informed decision when choosing a floor plan.
