One specific cost pressure in Denver is the combination of high property values and rising property tax bills.

Renters are also affected indirectly since landlords pass rising property costs through in rent increases. Areas in Denver's eastern suburbs and in cities like Aurora and Lakewood offer somewhat lower rents while still providing access to the metro's job market.
