Is it sustainable to take on a mortgage that equals 45% of my net income?

My wife and I buying a Utah home under special financing face a $2,500 monthly payment on a $379,000 property while earning $5,600 monthly. Has anyone managed this ratio?

Mortgage at 45% of net means tight budget limits. Does anyone with similar ratios have spare funds for emergencies? I’m curious about your experiences handling unexpected costs.
