Analyzing the Pace of Housing Inventory and Demand

Question: When should I expect more homes to be put on the market for sale?

Answer: 2020 was an unusual year for housing inventory because we saw so little inventory come out during the spring, when the pace of new listings peaks, and an explosion of listings, especially condos, from late summer through the holidays. Here’s a link to a column I wrote that visualizes how unusual 2020 was for housing inventory in Arlington. Even though my analysis in this column and previous columns focuses on Arlington, similar patterns show up and can be applied across the DC Metro.

It is much more likely that the pace of new listings will follow a more traditional pattern this year, with the number of homes listed for sale increasing steadily from now to the spring, peaking for about mid-March to mid-May, and then dropping steadily through the rest of the year, with a brief post-Labor Day spike.

Weekly Pace of Listings, by Housing Type

I’ve always shared and seen monthly breakdowns of listing inventory, so I thought it would be interesting to break it down a bit further into a weekly chart and see if there’s a noticeable difference in the seasonal pace of new listings of single-family homes/townhouses and condos.

The following chart does just that and pulls data from the five years spanning 2015-2019 (I threw out 2020 because it’s an anomaly). The weekly percentages represent that week’s share of total annual listings. Note that the data for the first and last weeks of the year aren’t always full weeks because of how Excel calculates weeks.

As it turns out, the pace of listing inventory for single-family homes/townhouses and condos is nearly identical throughout the year, aside from a slightly higher pace for SFH/TH in the middle of the spring and a slightly lower pace for SFH/TH during the dog days of summer.

What can buyers looking for a home in 2021 take away from this chart? You can expect a significant increase in listings beginning around mid-February, buckle-up for the most options in April and May, plan your vacations in July and August, look-out for the post-Labor Day surge, and hopefully you’ve found your dream home by the holidays!

Weekly Pace of Listings, by Year

The pace of new listings remains pretty consistent year-after-year, as shown by the chart below. There were only a handful of weeks with unusually low listing activity, compared to previous years. I’m guessing there was major weather activity during those weeks that caused some homeowners to delay or accelerate their listings by a week or two to avoid the drag of bad weather.

The consistency you see in the five-year chart below is also reflected in longer (ten and fifteen year) charts, but those get a little too messy for display.

Weekly Pace of Listings and Contracts

The pace of listing inventory and contract activity is highly correlated. The “chicken or the egg” question is whether more/less listing activity drives more/less contract activity (demand) or does demand dictate listing activity or do buyers and sellers just have similar patterns of behavior and thus the pace of supply and demand naturally correlate?

I think that it’s mostly due to number three, a natural correlation of behavior patterns that cause the pace of supply and demand to move in tandem. This is also supported by data like the new-listing-to-new-pending ratios not being very seasonal.

Using the chart below, one could even make the argument that the best time to list a property for sale is the last 2-3 months of the year, when the pace of contract activity (demand) consistently exceeds new listings (competition). However, I’ve analyzed “success metrics” like days on market and sale-to-ask-price ratio based on the month a property is listed and overwhelmingly found that February-May/June produce the most favorable results for sellers.

I hope these charts were interesting and helpful to you! If you’d like to discuss buying or selling strategies, don’t hesitate to reach out to me at Eli@EliResidential.com.
