“There is a serious lack of new listings, and although prices are through the roof, homeowners are reluctant to sell, because it’s so hard to buy again unless you are moving to a less expensive area where you can afford to outbid other buyers,” said Redfin chief economist Daryl Fairweather. “Sellers who are concerned about finding their next home are asking buyers for a rent-back agreement, which allows the seller to stay in the home until they can move into their next one. Offering a rent-back agreement can also be a winning strategy for buyers with flexible timelines.”
