Below are charts for a handful of leading market indicators that update in real time, sourced directly from the San Francisco MLS. Scroll down to see the supply and demand trends measured by inventory, new listings, days on market and final selling prices.

Median Number of Days on Market prior to Acceptance of Offer (DOM)

Under 30 days is considered a fast moving market. Below 20 days reflects extremely high buyer demand for new listings. This figure would be even lower except that many San Francisco agents prefer to show their listings for 10 to 14 days before the seller even reviews offers, so as to fully expose the home to as many prospective buyers as possible and thus maximize the potential of a bidding war.

Median Sales Prices

Median sales price is that price at which half the sales occurred for more and half for less. It typically conceals a large variety of different prices in the underlying individual sales, and can also be affected by other factors besides changes in home values, such as seasonality and large changes in the distressed, luxury-home or new-construction segments of the market. Short-term fluctuations are much less meaningful than longer-term

Average Dollar per Square Foot Values

This statistic is based upon interior living space and doesn’t include garages, basements, decks, patios or rooms built without permit. Typically, square footage figures come from appraisals or tax records, but square footage can be measured in different ways and the figures can be unreliable. Also, a fair percentage of listings don’t even
report square footage so the statistic is only based on those sales that do. These values should be considered very general statistical approximations.

Number of New, Active, Pending & Sold MLS Listings

New listings are hugely impacted by seasonality, with a rush of new listings typically coming on market in early spring and early autumn, then dropping precipitously during the summer and especially the winter holidays.

The number of listings on the market at any given time is determined by 3 big factors: seasonality, buyer demand and the motivation of prospective sellers to sell. In the 5-year line chart, one can see the huge decline in
listings available to purchase at any given time over the past 4 years.

Percentage of Listings Selling over List Price

Large percentages of sales in which the price is bid up above asking price usually signifies spirited buyer competition for new listings. Before 2012, this percentage typically ran between 20% and 40% of sales. It has climbed to new heights in recent years. This is another statistic that is affected by seasonality: Higher percentages in spring and autumn, lower during the summer and winter holidays.

Median Percentage of Sales Price to List Price

This statistic is becoming distorted because many SF listing agents are underpricing, and sometimes egregiously underpricing, their listings. Still, sales prices consistently well above asking prices are a classic sign of
a very hot real estate market.
