Miami was the most competitive rental market this year, according to a new report from RentCafe. The South Florida enclave was followed by Grand Rapids, Orlando, Harrisburg and North Jersey.

RentCafe analyzed the 135 largest markets in the U.S. where data was available, examining metrics including the number of days apartments were vacant, what percentage of rentals were occupied, the number of prospective renters competing for an apartment, what percentage of renters renewed their leases, and the share of apartments completed this year. The firm then calculated a Rental Competitivity Index (RCI), to measure how competitive the rental market was this year.

Miami topped the list due to record-high occupancy and high lease renewal rates "a combination of factors — including the lack of state income tax, business-friendly climate and booming tech scene — attracted droves of Millennials and even Gen Zers looking to work and live in the Sunshine State," the report notes. On average, a record 32 renters competed for a vacant apartment in Miami, and rental units were filled in 25 days.
