Seems like a reasonable goal and you are on your way to achieve it. I think the question you need to answer is if buying a condo is right for you. Do you plan to stay in Seattle? Will a condo still cover your needs 5 years down the road? Or would you rather save for a little longer and buy a single family home that you can stay in for 10+ years?

Also, how does the condo and HOA fees fit your budget? Are you lowering retirement savings for the monthly payment?
