Dawn Gross and Tom Kent live in a crowded two-bedroom condo that overlooks a freeway. This home has cathedral ceilings and an open floor plan, but when you account for their two dogs, two turtles and seven fish, there is not a lot of room left for them. Furthermore, the noise from the freeway is a constant irritation, the tandem parking is inconvenient, and the laundry is jammed into the guest bathroom. Bottom line: It is time to buy a bigger home.
