In November 2021, the median sales price for new construction homes in Ada County was $601,301— passing the $600,000-mark for the first time. This is an increase of 39.8% compared to the same month last year.

This record reflects a variety of market factors that were present prior to the pandemic — namely increasing costs of land, labor, and materials — as well as the ongoing impact of pandemic-related shutdowns that continue to create delays in increase costs in the global supply chain. (recent article from the National Association of Home Builders provides more context on this, and includes comments from a local custom home builder, Steve Martinez of Tradewinds.)

Speaking with Christine Comstock, Managing Associate Broker for CBH Homes, she echoed these sentiments, particularly on the impact of materials on the final price of a new home: “Lumber is a constant moving commodity. We work hard to keep our pricing in check in the midst of a fluctuating market. We are averaging a 24% increase year over year.”

The external pressures causing delivery delays are also beginning to impact the number of sales for new homes, which were down 32.2% year-to-date compared to last year.

Also effecting new construction sales, is the uptick in existing inventory over the past six months. There were 426 existing homes available for purchase at the end of the month, an increase of 217.9% compared to November 2020.

There is a strong correlation between the existing inventory and new construction pending sales (properties under contract with an accepted offer that should close within 30-90 days). Looking at activity since January 2019, we have seen new construction pending sales go up when existing inventory dips, then begin to slip as existing inventory increases.

You’ll always have a certain number of buyers in the market that are strictly looking for a new home, but existing homes are often the starting point for many buyers looking for something that’s move-in ready. So as existing home inventory has been limited, some buyers shifted to the new construction market. Then as delays in delivery occurred, and as more existing inventory is becoming available, some are reverting back to the resale market. This ebb and flow may seem obvious, but the big takeaway is that the demand for homes remains strong in our area, and motivated buyers continue make purchasing decisions based on what’s available.

The strong and consistent demand for housing is apparent when examining the Months Supply Inventory (MSI) metric, which takes the number of homes for sale divided by the average number of sales by month for the preceding 12 months. As of November 2021, Ada County was at just 0.9 months for existing homes and 1.5 months for new construction. This means, if no additional homes were listed, the supply of homes for sale would run out in less than two months. A balanced market — not favoring buyers or sellers — is typically between 4-6 months of supply.

Notable statistics from November 2021:

  • The median sales price for existing homes was $510,000, up 19.7% year-over-year and a slight 1.9% drop from October.
  • Existing homes were spending an average of 25 days on the market before going under contract, 92.3% longer than the 13 days we saw a year ago.
  • Total sales were down 7.8% from a year ago, primarily from delays in the new construction segment, as existing sales were up 3.5%. More existing inventory resulted in more existing home sales.
