Frequently asked questions

What is the 30% rule for housing?

A widely cited rule of thumb is that total housing costs should stay under 30% of gross household income. HUD uses the 30% threshold to flag 'cost-burdened' households and 50% for 'severely cost-burdened.' The rule is a starting point, not a hard limit.

What costs are included in this comparison?

The slider compares your 30% monthly budget against each county's median monthly owner cost with a mortgage (Census ACS table B25088). That figure includes mortgage, real-estate taxes, insurance, utilities, and HOA fees. Your actual number depends on down payment, rate, and home price.

How many US households are cost burdened?

According to HUD CHAS 2017-2021, about 44.5% of US households pay 30% or more of income on housing, and 20.7% pay 50% or more.

Where does the county data come from?

Median owner cost, home value, rent, and income figures come from the Census ACS 5-year estimates. Fair Market Rents come from HUD. Cost-burden rollups come from the HUD CHAS dataset.
