alt Hacker News[1] tells me a $350k mortgage with a 10% deposit, paid off over 15 years, costs $2,585 per month. That's $31k a year.
That kind of income with that kind of house price should be pretty comfortable, given you don't mention supporting a family. If your non-housing bills are costing $109k a year, there's a good chance you could reign in your lifestyle choices.
When many people talk about a salary of $140k, they're using pre-tax numbers. $140k can easily shrink to $90k, $80k or even $70k after tax.
