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 to are reporting any issues filling vacancies.

We see high demand, particularly for short-term rentals, from people moving to Idaho from other states. This helps explain the jump in four bedroom single-family rentals to $2,044 in Q2 2018 (all-time record high).

The significant uptick we saw in multifamily vacancies in the first half of last year, most likely due to the completion of a number of new construction projects, has mostly reversed itself. For 2017 as a whole, vacancies rose to 3.35 percent, up from 3.10 percent in 2016. Still much lower than the 5 percent rate we saw at the beginning of last year.

The increases in single-family vacancies we saw in 2016 did not continue into 2017. Last year we saw vacancy rates drop to 2.98 percent from 3.30 percent in 2016.

While vacancies increased in 2016 compared to the year before, it is essential to keep in mind vacancies in 2015 were near record lows. Historical market vacancy rates average 5-6% for both single and multifamily rentals.


The median home price in Boise, ID metro area (Ada County) is $320,260. In the fourth quarter of 2018, the median sales price for duplexes was $299,450, $560,000 for fourplexes and $677,450 for apartment buildings.


Rents at 30% or below household income are typically considered affordable. In fact, many property management companies require an income of at least 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, it is apparent supply at the higher price points is catching up with demand. In Boise, last year we saw the completion of the Arboretum (162 units), Havenwood (48 units), Kensington (323 units), The Fowler (159 units), The Watercooler (37 units), Tree Valley (32 units).
