A rough answer, plus the assumptions behind it — because your real number depends on your full financial picture.
Using an illustrative 6.75% 30-year rate and a 20% down payment ($200,000), a $1,000,000 home runs approximately $5,800–$5,900 per month for principal, interest, taxes and insurance (before any HOA dues).
Applying a 28%–36% housing-to-income guideline suggests a gross income of roughly $197,000 to $253,000 per year. At this price point, most Denver purchases require jumbo financing, and lenders typically look closely at cash reserves in addition to income.
Buyers with significant assets but variable or complex income (business owners, executives with equity compensation) often explore asset-based or alternative qualification alongside traditional income-based underwriting.
