How much you need to earn to rent in Lake Cassidy

Many landlords and housing programs use 30% of gross income as the most a household should spend on rent.

At that guideline, the median gross rent of $1,734 a month ($20,808 a year) needs an income of about $69,400 a year.

This is arithmetic on the published medians, not a rule any landlord must follow; screening criteria vary and some places limit how income may be weighed.

Income against housing costs since 2015–2019

2015–2019 and 2020–2024 American Community Survey 5-year estimates
	2015–2019	2020–2024	Amount of change	Verdict
Median household income	$99,531 (±$9,209)	$113,403 (±$14,608)	+13.9%	No measurable change after inflation
Median gross rent	$1,722 (±$1,028)	$1,734 (±$607)	+0.7%	No measurable change after inflation
Median home value	$469,200 (±$56,130)	$705,000 (±$66,234)	+50.3%	Up after inflation

The Census Bureau publishes 2015–2019 dollars in 2019 dollars and 2020–2024 dollars in 2024 dollars.

Prices (the CPI-U, US Bureau of Labor Statistics) rose 22.7% between 2019 and 2024, so a dollar figure’s verdict compares the two after raising the earlier one by that much, using the Census Bureau’s test for a difference.

The two periods do not overlap, as the Census Bureau recommends for 5-year estimates.
