I’m 21, living in Washington State and I’m looking to move out for the first time.
My current job pays $26.40/hour, 40 hours a week, and I’m potentially starting a second job in plumbing that pays $22/hour, also 40 hours a week.

I’m looking at 2-bedroom apartments, ideally in a decent/safe area, and I’ve been seeing places around $1,500–$1,800/month. I’m also a dad, so having a comfortable place for my son is important to me.

A few questions:

What would you consider a reasonable rent budget with this income?
Would $1,700/month be comfortable or am I stretching myself?
How much would you recommend having saved before moving out?
What expenses do first-time renters usually underestimate?
