800 K house for my income?

[Jack Komson]

Hi!
Can I afford $780,000 house in my situation?
1) 20% down payment 2)my credit score - 800, wife's credit score - 750. Title will be on both of us, morgage only on me.
3) 31 years old
4) a stable job at a large corporation that I started 6 months ago: $159k base salary+10% bonus+$15k special bonus+$16k in stock for next 4 years (vested annually); good health insurance
5) $10k car loan
6) no other debt
7) pregnant wife (1 child coming soon)
8) wife is a university student and still has 2 more years; $16k in annual tuition. It is very plausible she will get at least $60k job after graduation

Thanks!
