The Redfin Housing Demand Index is the industry’s first and only measure of housing activity prior to purchase. It is based on thousands of Redfin customers requesting home tours and writing offers in 15 major metro areas. The Demand Index is  seasonally adjusted, with 100 representing the baseline level of homebuyer demand posted in January 2014. All periods thereafter can be compared to one another in a relative sense. For example, a Demand Index reading of 116 in January 2015 implies that homebuyer demand in that month was 16 percent higher than it was in January 2014. Similarly, a level of 120 in June 2018 means that demand was 20 percent higher than it was in January 2014, and roughly 3 percent higher than in January 2015.

Redfin will publish its Demand Index on the last Tuesday of each month at 8 a.m. Eastern time.  The Demand Index will use available information at the time it’s run (the middle of the following month), but due to the smaller sample sizes and variable reporting times from different Metros, the latest Demand Index value for each Metro may be revised on the subsequent release.

Redfin is the only U.S. real estate brokerage that can track every tour and offer at scale because its agents are employees of the company who all use the same technology platform to track their work and client activity.

Tours are weighted by averaging the number of tours per written offer. The index adjusts for Redfin market share growth by taking the raw number of tours and offers in a given month and dividing by an exponentially weighted sum of Redfin’s share of sales over the prior six months. Sales activity outside of the portions of the market in which Redfin operates are accounted for by assuming demand follows a lognormal distribution with respect to price. The undersampled parts of the distribution are filled in using Redfin’s offer and tour information from the well sampled portions, and utilizing a maximum likelihood estimation approach to calculate the parameters of the whole lognormal distribution. This allows us to calculate the shape of the entire demand distribution using our available tour and offer data. Finally, we employ a statistical technique to estimate and remove statistical noise and the predictable seasonal patterns in the data to arrive at a seasonally-adjusted demand series.
