Does Seattle cap rent increases?
Not as a national rule, and not as a rumor. Coverage is an address-and-housing-type question. Seattle has local just-cause and rental-housing rules on top of RCW 59.18. Confirm coverage with the City, then the state chapter. Ask Renting in Seattle. Then read Washington Residential Landlord-Tenant Act for the Washington floor.

A lease still in term is not the same as month-to-month. The letter in your hand may be a renewal offer, a notice, or something that does not apply yet. Keep it. Do not treat a blog percentage as the law.
