Residential Investment Property Summary and Outlook

Pandemic-driven demand for rentals is pushing vacancies to record lows throughout the Boise metro area.

Boise's significant population growth over the past ten years was only accelerated as COVID-19 gripped the country at the beginning of 2020.

People are fleeing overpriced and overcrowded coastal cities as work-from-home flexibility has become a reality for many.

Limited inventory and increased demand have caused local home values to surge to new records.

Despite average rents increasing 26% over the past three years, strong house price appreciation in the purchase market continues to keep renting, at least somewhat, affordable by comparison.

The shortage of properties in the purchase market is driving potential buyers to the rental market.

At the end of 2020, single-family vacancies declined to 1.5%, down from 2.95% the year prior. Multifamily vacancies fell to a record low of 0.69% from 2.32% in 2019.

When vacancy rates rose above 4% in the second quarter of 2020, it appeared to us to be more a reflection of the reluctance of renters to move during a pandemic than inherent weakness in the rental market. The first quarter of 2021 has made it vividly clear – demand for rentals is almost literally off the charts.

Both single-family and multifamily rents are at or near all-time highs. At the beginning of 2021, we saw the most popular unit types for each, three-bedroom houses and two-bedroom apartments, jump to new records of $1,934 and $1,249, respectively.

Still, recent rent price records are more of a reflection of demand than aggressive price increases by landlords. At the beginning of 2021, by our calculations, more properties may be below market rates than at any other time in the last three years. However, a new round of rental increases in the first half of 2021 is beginning to close the gap (albeit only slightly).

Property owners had initially been reticent to raise rental rates as the pandemic set in and were slow to catch up.

While record-low vacancy rates may have been brought on by a confluence of events that are not likely to repeat themselves, market forces will continue to keep vacancies below their long-term averages (and rental rates high) for the foreseeable future.

Note: Historical market vacancy rates average 5% to 6% for both single and multifamily rentals.


The median home price in Boise, ID (metro) is $506,089. In the first quarter of 2021, the median sales price for duplexes was $550,000, $775,000 for fourplexes, and $1,100,000 for apartment buildings (defined as five or more units).


Rents at 30% or below household income are typically considered affordable. In fact, many property management companies require a minimum income of at least two and a half to three times the asking rent. Based on U.S. Census data, the median household income in Ada County is $66,293, equating to rents of $1,657 per month.
