Income Needed to Afford a $600,000 House (2026)

$600,000 is the median or near-median price in many of America’s most desirable metro areas — Portland, Denver, Austin, Nashville, and the suburbs of Washington DC and Boston. At this price point, you are buying into competitive markets where bidding wars, waived contingencies, and strong pre-approval letters are the norm.

The income required is roughly $166,000 with 20% down — a level that typically means two professional incomes or a high-earning single professional in tech, healthcare, law, or finance. The $120,000 down payment plus $18,000-$30,000 in closing costs means the total cash outlay exceeds $140,000 before you move in.

At $600K, the interest rate has an enormous impact on affordability. The difference between 6% and 7.5% on a $480K loan (20% down) changes the monthly P&I by nearly $500 and the income needed by roughly $21,000/year. This makes rate shopping — getting quotes from at least 3-5 lenders — one of the highest-value activities in the home buying process. A 0.25% lower rate saves approximately $72,000 in interest over the life of the loan.
