Besides looking for an oven that's big enough to cook a Thanksgiving turkey, make sure the range has two burners big enough for large pots. If you have young children, life will be easier if cooktop controls are out of their reach. If your children are in elementary school, it's prudent to position the microwave oven at a height where they can warm food. Older people may appreciate wall ovens and a dishwasher raised a foot higher than the standard toe kick starting point. If you depend on a lot of small appliances, electrical outlets should be positioned where you're likely to need them.
Most model homes offer double sinks.
Basins at least seven inches deep are more practical than shallower offerings. Stainless steel may be standard. The more nickel, the higher the quality, too. Ten percent nickel is best. Determine if the enamel sink in the model is an upgrade.
