I live near this now, and my answer is mixed. separate the monthly budget from the arrival budget. The monthly budget has housing, cars, childcare, utilities, insurance, and activities. The arrival budget has deposits, furniture, movers, repairs, hotel nights, and all the annoying things nobody posts on Instagram. In Seattle & Bellevue, dark winters and housing prices are the two categories I would not underestimate. A move can still be financially smart and still feel expensive during the first six months.
