Agree. It was an exaggerated suggestion to emphasize a point. One way to determine is by factoring property square footage into a formula that caps the size of a home and the amount of parking required on the property to accommodate the living capacity within the house. Ex: 5,000 sq.ft. property allows for a maximum 2500 sq.ft. home with 2-car garage. Bottom line: it has to be viewed from a more comprehensive thought approach than a single focus of the size of the home only. There's also parking, sewage, refuse collection, taxes, etc.
