True, most would-be homebuyers and sellers in colder climates still call it quits from late November until late February or so.
But Knapp says consumers who face job relocations, divorces or other situations requiring an immediate move keep the market humming all winter long.
"There are fewer buyers and sellers in the marketplace during the winter, but they're all serious buyers and sellers," he says. "They all have a sense of urgency or they wouldn't be in the market at all."
But how can a would-be seller attract a buyer when there's ice on a home's walkway, snow covering the flower beds and little natural light to make a place look bright?
Here are five things Knapp says homeowners must do if they want to heat up the chances of selling a property this winter:
1. Set a realistic price
House hunters expect discount prices in the winter, because they know that any homeowner who lists a property during the period really needs to sell. So Knapp recommends that sellers list their homes at realistic prices to begin with — without any extra "air" for haggling.
"We've been in a buyers market for so long now in most of the country that buyers are trained to lowball," he says. "The best way to avoid that is to price a home accurately in first place."
If possible, you or your agent should commission your home's advertising photos before it snows. If that's not feasible, make arrangements to have a photographer come out the first time the snow melts — even if it's just a brief winter thaw.
You always want your home to have good "curb appeal" — a nice appearance that's apparent from the moment a would-be buyer pulls up to the curb — but winter snow and gloom make that tough.
A good real-estate agent or professional home stager can help you make your home's interior look warm and friendly no matter how dreary it is outside. Knapp says you should start by decluttering the home, putting as much stuff as possible away — preferably in offsite storage — to make your home look clean and roomy.
You always want your home to look as bright as possible to potential buyers, but sparse winter sunlight can make that a real challenge.
