A floor plan. When you visit an apartment complex to look at an apartment to rent, the first thing the manager does is hand you floor plans of their apartments. When a family has a floor plan of a house or apartment that they are thinking about moving into, they can begin to visualize where furniture would go and how each room would be used. When a family is going to move into an apartment complex, they look at the apartment floor plans for two weeks solid imagining where the computer will be going, where the TV will sit, and where they would position the stereo speakers. The same holds true for commercial lease or buy property.
Floor plans work.
They keep your property in a prospective buyer's mind long after they have left. Go into any drug store and you'll find a dozen magazines or books full of home plans. Because people love looking at them. Open the Sunday World Herald's Real Estate section and you'll find a model home with a floor plan. Macman Graphics can produce a sales flyer for a property unlike anything you've seen.
