What a typical home costs per month in Oklahoma
A home valued at the Oklahoma median of $199,800 (the Census Bureau's figure for owner-occupied homes), bought with 20% down at 7.4% over 30 years, comes to about $1,306 a month. That is $1,107 in principal and interest, $133 in property tax and $67 in insurance.
Over a year that is 24.1% of the state's median household income of $65,039. Keeping housing costs near 28% of gross income would take a household income of about $55,992.
