Sales of previously owned homes have fallen for 10 consecutive months. It's making some home sellers so desperate they're offering buyers cash to purchase their properties. It all comes down to the Federal Reserve's ongoing fight against surging inflation, which has effectively put an end to pandemic-era mortgage deals. With higher monthly mortgage payments and near-record-high home prices, fewer Americans are purchasing homes. Indeed, data from real estate brokerage Redfin indicates that in the fourth quarter of 2022, home sellers gave concessions -- such as money for home repairs and mortgage-rate buydowns, a technique in which a seller pays a fee at closing to secure a lower mortgage rate for a buyer -- to buyers in 41.9% of home sales. That's the highest rate Redfin has ever recorded over a three-month period. "Buyers are asking sellers for things that were unheard of during the past few years," Van Welborn, a Redfin real estate agent from Phoenix, said in the report. "They're feeling empowered, partly because their offer is often the only one, and partly because they know sellers have built up so much equity during the pandemic that they can afford to dole out sizable concessions. "With fewer deals taking place, home prices are falling in cities across the country -- even in previously hot markets like Austin and Phoenix. According to Redfin, a record 22% of home sales made by its agents in the fourth quarter of 2022 included both a concession and a final sale deduction. Additionally, a record 19% included both a concession and a listing-price cut while the home was still on the market, and a record 11% included all three incentives.Brian Lewis, a housing expert and broker with Compass real estate, says that in cities like Los Angeles and Chicago a general lack of homes for sale is also helping shift the market in favor of buyers. "Here's the thing about America, we don't have inventory," Lewis said in an interview on Fox on Thursday. In Richmond, Virginia, it's tight. In some areas of Chicago, it's tight. When home prices and mortgage rates are both high, buyers are reluctant to dive in. That means sellers need to compete for the few that are willing to make offers under such conditions. Lewis said these dynamics have made it unmistakable that "homebuyers have way more power" than sellers. "It took a while, but seller expectations are coming back down to earth," Welborn said.
