Understanding Closed Sales Data in Real Estate

Closed sales data tells the real story of a market. Learn how to read it and use it to your advantage as a buyer or seller.

Closed sales data is the most accurate picture of what's actually happening in a real estate market. Unlike list prices or pending transactions, closed sales represent real money - what a buyer actually paid and what a seller actually accepted. In South Bay, we analyze closed sales weekly across every zip code to track where prices are moving, how quickly, and whether sellers are getting above or below their asking price.

The key metrics to watch are: median sold price (what the middle transaction looks like), average days on market (how long homes sit before going under contract), and sale-to-list ratio (the percentage of asking price sellers are actually receiving). When the sale-to-list ratio exceeds 100%, it signals a competitive market where multiple offers are common. In peak years in Manhattan Beach, we've seen averages of 103–107% above list.

One number many buyers overlook is the months of supply. This represents how long it would take to sell all active inventory at the current rate of closed sales. Below 2 months is a strong seller's market. Above 5–6 months shifts toward buyers. The South Bay beach cities have consistently operated at 1–2 months of supply for most of the past several years, which explains the sustained price appreciation we've seen.

For sellers, understanding closed sales in your specific neighborhood - not just citywide - is what separates a precise pricing strategy from a guess. Two homes on the same street can have dramatically different closed sale comparables depending on their age, remodel status, and lot size. Our team builds custom comparable sets for every listing so our sellers price with precision rather than optimism.
