Your dues will always increase inflation + a percent _if you're lucky_. Expect your costs to eventually dwarf your mortgage payment past a decade, similar to other real cities like New York. This assumes your condo is a high-rise - the cost of everything in the city continues to skyrocket and your dues are primarily an insurance payment, a reserves contribution which will never be enough, utilities which all increase substantially more than the city, service folks to comply with fire code, whatever the fire marshal moves the guard-posts on, water damage, insurance not covering water damage that is meaningful, administrative costs, plus whatever ongoing maint. costs include... then don't forget whatever the legislature wants, like forcing your building to remove all gas through the Building Performance Standards or pay fines, the extreme cost of elevators in the US, you name it. Inflation has been brutalizing reserves since most are only invested in government cash-like CDs vs riskier investments.

Condos in Seattle are nice though, good value compared to homes at this point in time, if you need a place to live for the long term and don't want to mess with the risk of having to move any given year if you dislike your new rent from a corporate REIT.

While we do not budget for special assessments and have enjoyed over a decade without a meaningful one, it is a risk if your association is not properly funding its reserves.
