[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.
Don't forget real estate tax and sales tax. In some places, real estate tax is about 20-30% of the rental cost. Sales tax is as high as 10% in some places.
But that's not $140->$70 after tax, that's $140k->$70k after tossing $24k into retirement investment savings, another $5k into healthcare savings, possibly another $1,500 towards healthcare premiums (huge amount of variability there), and then finally taxes.
