Home prices in Seattle saw little change from August to September, an indication of a seasonal slowdown in the local market. 

Earlier this year, Seattle-area home prices saw month-to-month increases between 3-5%, according to the latest S&P CoreLogic Case-Shiller Home Price Index. 

While the slowdown is on track with national trends, Seattle home prices are still up 23.3% from the same time last year. 

The Case-Shiller index monitors a three-month rolling average of home prices in parts of King, Snohomish and Pierce counties. Because the measure lags by two months, the latest data reflects sales in September.

Seattle price growth ranked seventh in the country behind Phoenix, Tampa, Miami, San Diego, Dallas and Las Vegas, the report noted. Compared to last year, Seattle prices rose faster than Los Angeles, New York and San Francisco. 

All 20 major cities the index tracks reported all-time high home price growth compared with a year ago.
