Vacancy Rate for Rentals in the Boise Idaho Market:
First Rate Property Management's current vacancy rate is 1.6%. In the week ending March 31st, FRPM's vacancy rate was 1.1% as compared to 2% - 4% for the Boise/Nampa area rental markets.

Boise/Nampa Area Rental Market Summary:
All indications from the Q1 2013 survey are that the rental market is highly favorable for rental property owners enjoying low vacancy rates and rental rates rising even over the frigid winter. Vacancy rates continue to hold an impressive position in Ada County that is notably better than the national average. All market segments surveyed in Ada County saw an increase in rents with the exception being 5-bedroom, single-family homes, which is a segment with an often limited amount of data and therefore larger margin of error.

Canyon County saw a significant improvement in the multi-family vacancy rate, which was previously a drag on rental performance in the county. With this improvement, vacancy rates by every measure in the Treasure Valley are outperforming national averages. Rents increased for all Canyon County market segments other than one-bedroom, multi-family, which was flat.
