Annual Household Income: $240,074

💡 What does Household Income mean?

Includes: wages, salaries, self-employment income, Social Security, pensions, investments, unemployment, public assistance, and rental income.

Does NOT include: capital gains, non-cash benefits (like food stamps), or tax refunds.

Household = any group of people (or a single person) living in the same housing unit.
