Rent: the biggest variable by far
Da Nang and smaller cities offer serviced rooms — furnished, with weekly cleaning, sometimes a pool — from around 6-9m VND a month, which is why so many first-time teachers start there. In Ho Chi Minh City, District 7's Phu My Hung area is noticeably cheaper than Thao Dien or central District 1, where a comparable one-bed studio can run 12-16m VND or more.
Hanoi splits similarly: rooms in Cau Giay or Tay Ho's quieter streets undercut the lakeside apartments popular with expats. Sharing a two-bed apartment with another teacher is the single biggest saving lever most people skip in their first month.
