Home sellers now substantially outnumber home buyers in the U.S., indicating a shift to a buyer's market, according to an analysis released on Thursday by real estate brokerage Redfin. A year ago, sellers outnumbered buyers by a smaller 6.5%. Redfin estimates that 31 of the 50 most populated metropolitan areas are buyer's markets, where sellers outnumbered buyers by at least 10% in April. The biggest buyer's market in the U.S. is Miami, Florida, where there are 197% more sellers than buyers with a median home sale price of $574,696. The strongest seller's market was Newark, New Jersey, with an estimated 5,200 sellers and nearly 10,000 buyers in April.
