CHICAGO—The US dollar store sector has continued to expand in the past year due to consumers’ demand for low-cost goods. That expansion has also opened up a lot of opportunities for investors that want to jump into this robust segment of retail. Cap rates for single tenant net lease dollar stores increased by 15 bps from the second quarter of 2015 to the second quarter of 2016 to a 6.65% cap rate, according to a new report from the Boulder Group, a net lease firm in Northbrook, IL.
