Concerned about increasing property taxes as valuations soar

My husband and I bought our home in 2013. We love living in Bellevue but we could not afford to buy the home we are living in if we had to buy it today. Each year our property valuation increases and last year the valuation increased by over $500,000. I am really concerned that as we retire and live on a fixed income that we won't be able to afford to continue to live here. I love our neighborhood as we can walk to parks and many services such as a grocery store and restaurants.
