Whether you use a Realtor or hang a for-sale shingle yourself, the house you’re trying to sell needs to look enticing. You could spend weeks sprucing the place up yourself, or get Lisa Kauffman Tharp to do it for you. A Boston College grad and former HBO producer, she’s the area’s premier home-staging consultant. She rethinks and rearranges rooms, renting updated furniture, hiring house painters, and minimizing accumulated tchotchkes. Studies show staged houses spend half the time on the market that their as-is brethren do—suggesting that sometimes you have to spend a little to make a lot.
