October 2018 Market Report


 Key Takeaways:

  • October 2018 marks a full four years of falling inventory, specifically in the number of existing homes for sale in Ada County.
  •  This lack of inventory compared to demand is one of the primary reasons that the median sales price continues to rise compared to last year.
  •  The median sales price in October 2018 was $321,398, up 0.8% from the previous month and up 19.9% from October 2017.


October 2018 marks a full four years of falling inventory, specifically in the number of existing homes for sale in Ada County, when looking at activity by month year-over-year.

There were 870 existing homes for sale in Ada County in October 2018, down 15.0% from October 2017 and down 48.8% from October 2014 when the decline began.

As we’ve outlined in previous reports, there are many reasons the Boise Region is facing a lack of homes for sale. These include the continued population growth, the trend of people choosing to stay in their homes longer than we’ve seen historically, among others.

This persistent lack of existing home inventory is one of the two primary reasons that the area’s overall median sales price continues to rise compared to last year; the second reason, increasing land, labor, and material costs for new homes. For October 2018, this resulted in a median sales price of $321,398, up 0.8% from the previous month and up 19.9% from October 2017.

This nearly 20% increase year-over-year in the overall median sales price for October was primarily due to a higher share of new home sales during the month ― reaching 27.7% of all closed sales, up 10.1% compared to October 2017.

We’ve been talking about the drop in existing inventory literally for years now, but what’s interesting about today’s market is that we’re seeing more and more new construction sales. Whether you’re looking to buy an existing home or a new build, your REALTOR® is going to advocate for you throughout the transaction. And if you’re thinking of selling, these recent numbers indicate that despite the turn in temperature, it’s still a good time to put your home on the market.


In October 2018, 36 homes sold in Gem County, up 28.6% from October 2017. This left 57 new and existing/resale homes available for sale at the end of the month — down 19.7% from the same month last year. Despite persistently low inventory, Gem County has seen strong sales numbers for the last four months.

The median sales price for homes that sold in October was $199,450, based on activity over the past 12 months — up 11.1% over the same period last year. There are two primary reasons that the median sales price rose compared to last year — the lack of inventory compared to demand, and an increase in the share of new homes sales in October.

Five new homes sold in Gem County in October 2018, the same number as October 2017. However, new home sales made up a larger share of total sales at 11.1% in October, compared to the average of 5-6% we typically see in Gem County. New homes typically sell for higher prices than existing homes due to increased land, labor, and material costs, so when the share of new home sales increases, so does the median sales price.

Apparently, the colder temps haven’t deterred buyers in Gem County. If you’re thinking about selling, now is a great time to put your home on the market. Talk your REALTOR® to find out what your home may be worth and what options are available based on your specific situation.

“Getting to Solutions” Listening Session on Growth

Getting to Solutions

Soren Dorius, Director of Government Affairs for BRR, started the listening session by sharing some key findings from the Second Annual Treasure Valley Survey a survey conducted by BSU to explore public opinion on growth, transportation, and other issues. This project was funded in part by a $15,000 Smart Growth Grant secured by BRR.

The group shared ideas and solutions about how to maintain the quality of life during this time of growth, thoughts on what area would be the next good candidate for higher density projects, what features and places need to be “off limits” to development, the role of transportation, how REALTORS® can participate in public meetings, and much more.

Residential Perspective on the Recent BOMA Meeting

A few members have asked for our thoughts on the IBR article about a recent BOMA meeting.

At that event, speakers discussed the need for commercial real estate professionals and developers to prepare for a market downturn and understand the elements that are transforming how the commercial market operates.

On the residential side, Boise Regional REALTORS® (BRR) and other industry economists, do not sense a major downturn is imminent in our local housing market. In contrast to the commercial market, the residential market is peaking, at least in terms of prices, due to exceptionally low inventory levels compared to the number of buyers moving into our area. It’s classic supply and demand that is pushing up prices.

As noted the IBR article, all markets are cyclical, both commercial and residential. In the housing market, many cite economist Homer Hoyt, who found an 18-year cycle between market peaks. Looking out from the last market valley, some economists are forecasting that the housing market will continue to grow through 2024 or 2026, with market fluctuations between now and then, barring any unforeseen world events or disruptions.

The hope is that when the market cycles back down, it won’t drop back into a recession, but shift back to a more balanced market for buyers and sellers. BRR will continue to watch trends in prices, inventory, unemployment, wages, and economic development, and educate our members on any changes.

While BRR does not make official forecasts, we agree with the sentiment that to survive in real estate long-term, agents must be able to adapt. That requires a solid foundation of professional practices and knowledge, while continuously learning about new trends, consumer needs, advances in technology, and changes to legal and regulatory environments.
