There's the minimum amount you'd need to qualify for a mortgage. (the lender)

There's the Dave Ramsey 25% of net take-home toward a mortgage.

and then there's somewhere in the middle, with 30% of your gross income.

This is assuming a 5% down payment and a 0.25% mortgage insurance factor for a conventional loan and $0 other debt.
