We know it's cold out there, especially if you've got an apartment to sell. But the heat is always on in Curbed Marketplace, our property listings board. And this month, we're turning it up a little with a very special offer: List your for-sale property anytime before January 31 and pay just $25. That's half off! You'll get the same glorious full-page listings, with unlimited photos, full-length descriptions, broker profiles, and links back to your property page. More importantly, you'll get in front of our audience of more than 250,000 real-estate-obsessed New Yorkers. So go on, give it a go.
