San Diego's home prices are rising rapidly, ranking second in the country. The president of the San Diego Association of Realtors attributes this to inflation and high demand. San Diego's annual home price increased by 6.5% in September, the highest in two years. Experts predict that prices will continue to rise due to a lack of inventory. Construction costs and other expenses make it difficult to increase housing supply. The low number of home sales in September contributed to the price increase.
