Axiometrics Analytics researcher Sophie Zatterstrom Gore looks at 28 metro areas throughout the country to get an idea of where rents were the most affordable in 2015 as well as further in the past, and where they are expected to be the most affordable in the future.
Gore looks at rent to income ratios, looking at 30% or more of income spent on rent as unaffordable, noting that Little Rock, Salt Lake City, Las Vegas and Indianapolis score as most affordable. Gore writes:
Each dot is color-coded according to its 2015 rent-to-household income ratio. It ranges from light yellow for markets with a rent-to-income ratio less than 20%, to red for markets with ratios from 50-54%.
