There are a lot of opinions on how this should look, so I'll give a few scenarios with estimates.

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.

This is also accounting for property taxes and homeowners insurance. So states with higher escrow (taxes/insurance) will see a lower max purchase amount.

part three: 30% gross income rule

This is what a large majority of people will agree on, or at least around this amount. This doesn't take into account income tax. Just gross percentage of your income
