"To not power-wash the exterior or leave mud dauber and wasp and bird's nests in your eaves and above your doors? You've got to be a fool to do that."
Whether inside or out, less is more when it comes to clutter.
"I usually start in the closets," Dana says. "Your closets should be half-full with nothing on the floor. Why? Because most people looking for a house have outgrown their previous house. Showing them that you've still got room to grow gives them a reason to buy."
Kitchens and built-in bookshelves should showcase spaciousness by following the rule of three. For kitchens, there should be no more than three countertop appliances. Meanwhile, bookshelves should be divided into thirds: one-third books, one-third vases and pictures, and one-third empty.
The home office should be very generic so any type of professional can imagine living there, Dana says.
"Otherwise, it can be a distraction: 'What does he do for a living? How much money does he make?'" she says.
Dana's tip for toddler parents is to pack away extraneous "kiddie litter" and keep a laundry basket handy.
"When you get that phone call one hour before a showing, toss everything in that basket and take it to the car with you and your kids, and you're all set," she says.
