What this means for your life
Typical rent runs $2,501 a month in Seattle versus $2,941 in Boston, so Seattle is 15% cheaper. A meaningful but not dramatic gap. Factor it into your budget alongside salary differences between the two markets. Over a year the spread is about $5,280, enough to notice in savings, not enough to ignore schools, safety, or pay. Seattle still wins on housing cost; just do not let a 10–20% rent edge override a job that only exists in Boston.
