Every figure is modelled on the county's own median home with 20% down at 7.03%. Property tax and electricity are county and state specific; homeowners insurance uses the NAIC average premium for that state, which ranges from 0.16% of home value in Hawaii to 1.16% in Oklahoma. Maintenance and water are national estimates. Full methodology.
