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.

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 rental rates to $2,044 in Q2 2018 (all-time record high).

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 2018 as a whole, vacancies declined to 2.38 percent, down from 3.35 percent the year prior. Even that was lower than the 5 percent rate we saw at the beginning of 2017.

Single-family rents remain near all-time highs. Despite the average rent increasing 8.6% over the last twelve months, the strong price appreciation in the purchase market continues to keep renting attractive by comparison.

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% for both single and multifamily rentals.
