Residential Investment Property Summary and Outlook

Demand for rentals throughout the Boise area continues to remain healthy. None of the property managers we have spoken with are reporting any issues filling vacancies.

The Coronavirus pandemic is creating new uncertainty in the purchase market for single-family houses, despite lower mortgage interest rates. We expect people that had been considering buying to show a slight preference for renting, at least for the near term.

Monthly rents for all property types are at or near all-time highs. Despite the average rent increasing nearly 15 percent over the last twelve months, the strong house price appreciation in the purchase market continues to keep renting, at least somewhat, affordable by comparison.

Additionally, we continue to see high demand, particularly for short-term rentals from people moving to Idaho from other states.

The significant uptick we saw in multifamily vacancies in the first half of 2017, most likely due to the completion of a number of new construction projects, has completely reversed itself. For 2019 as a whole, single-family vacancies declined to 2.95 percent, down from 3.04 percent the year prior. Multifamily vacancies declined to 2.32 percent from 2.38 percent in 2018.

While we continue to see a slight uptick in single-family vacancies, rates are still well below the long-term averages. Historical market vacancy rates average 5-6 percent for both single and multifamily rentals.


The median home price in Boise, ID metro area (Ada County) is $364,490. In the first quarter of 2020, the median sales price for duplexes was $367,000, $570,000 for fourplexes, and $1,000,000 for apartment buildings (5+ units).


Rents at 30 percent or below household income are typically considered affordable. In fact, many property management companies require an 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 $60,151, meaning rents of $1,504.


While there are no signs of a drop in demand for multifamily units from potential renters, we continue to see a steady stream of new supply, albeit at higher price points.
