$800,000 is the baseline reality in competitive coastal markets and an aspirational price point in mid-tier cities. In the greater Los Angeles basin, San Diego, Seattle, suburban New York, and even parts of Boise and Salt Lake City, $800K represents a typical family home in a decent neighborhood. The buyers at this level are almost exclusively dual-income professionals or single earners in the top 5% of incomes.
With 20% down, the income requirement is approximately $220,000. At this level, the mortgage payment alone exceeds $5,000/month, so maintaining adequate retirement savings, emergency reserves, and insurance alongside the housing cost requires careful financial planning. Just because a lender will approve you at 28% DTI does not mean you should max out that ratio — keeping housing costs at 25% of gross income provides a more sustainable long-term position.

Income Needed to Afford an $800,000 Home
Based on the 28% front-end DTI rule:
| Down Payment | Loan Amount | Monthly PITI | Income Required |
|---|---|---|---|
| 5% ($40,000) | $760,000 | $6,130 | $262,700/yr |
| 10% ($80,000) | $720,000 | $5,812 | $249,100/yr |
| 15% ($120,000) | $680,000 | $5,487 | $235,200/yr |
| 20% ($160,000) | $640,000 | $5,163 | $221,300/yr |
| 25% ($200,000) | $600,000 | $4,840 | $207,400/yr |
| 30% ($240,000) | $560,000 | $4,517 | $193,600/yr |
Assumes 6.75% rate, 30-year term, $800/mo taxes, $320/mo insurance. PMI included for <20% down.
At $800K, the jumbo loan threshold starts to become relevant. With 20% down, you are financing $640,000 — below the standard conforming limit of $766,550 in most counties. However, in non-high-cost counties, putting less than 15% down could push your loan above the conforming limit, triggering jumbo loan requirements: higher rates, stricter credit requirements (often 720+), and larger reserve requirements (typically 6-12 months of payments in liquid assets). If your loan is close to the conforming boundary, adjusting your down payment to stay under the limit can save you significantly in rate and qualifying hassle.
