The 10 most affordable places to live

% of monthly income spent on housing: 18.2%
% of monthly income spent on commuting: 8.3%
% of monthly income spent on utilities: 4.6%

Rising home prices and flat wage growth have reduced affordability in 89 of the 100 largest housing markets in the U.S., according to Trulia.

In Louisville, the median listing price was $159,900 with middle class homebuyers spending almost 13% of their monthly income on commuting and utility costs.

To determine affordability, Trulia calculated how much a median income household would spend on housing, utilities and commuting in the 100 largest housing markets in the U.S. To determine housing affordability, Trulia assumed a 30-year fix rate mortgage with a 4% interest on each metro's median home price based on Trulia's August listings. Property taxes and insurance were also included in the calculations. Trulia used data from the 2013 American Community Survey to determine the median monthly household expenditure on utilities (water, electricity and gas) and commute time to work in each metro.
