Methodology: How We Determined The Most Expensive Places To Live In The Evergreen State For 2025
The two most important things to think about when it comes to being able to afford a city in Washington are:
- How much money do I make?
- How much do I have to spend to live there?
You need to understand your costs in the context of how much money you make.
For example, if the median household earns $100,000 and spends $40,000 on housing, it’s actually cheaper to live there than a place with a median income of $50,000 and housing costs of $21,000. You might spend more on housing, but you have more money overall to play with.
With that example in mind, we derived several statistics from the latest Census American Community Survey 2019-2023 around incomes and costs. They are:
- Overall Cost Of Living Index
- Median Home Price / Median Income (lower is better)
- Median Income / Median Rent (Higher is better)
- Median Home Price
You can then compare these metrics in each of the places in Washington to figure out which is the most expensive.
You are left with a “Cost of Living Index” by taking the average rank of each of these metrics for each city.
So we used that cost of living index to rank all of the 119 places in Washington that have more than 5,000 people.
The place with the highest cost of living in Washington according to the data is Mercer Island. We updated this article for 2025. This article is our tenth time ranking the most expensive places to live in Washington.
