How Much Income for an $800K House? The 2026 Guide

To afford an $800,000 house, you'll typically need an annual income between $207,000 to $260,000, depending on your down payment, credit score, and existing debt.

This calculation follows the standard 28/36 rule used by most lenders, which limits your housing costs to 28% of your gross monthly income and total debt payments to 36%.

With a 20% down payment ($160,000) and current 2026 interest rates around 6.40% for jumbo loans, expect monthly housing payments of approximately $4,800 including principal, interest, taxes, and insurance.

Your exact income requirement will vary based on your financial profile and the lender's specific criteria.

The 28/36 Rule Baseline Calculation for an $800K House

Most lenders use the 28/36 rule to determine how much house you can afford. For an $800,000 home with a 20% down payment, your monthly mortgage payment will be around $4,800.

Using the 28% housing ratio, you'd need a minimum gross monthly income of $17,143, which equals $205,716 annually.

However, most financial experts recommend aiming for $220,000 to $240,000 to ensure comfortable affordability.

How Down Payment Size Affects Income Requirements

Your down payment dramatically impacts the income you'll need:

• With a 15% down payment ($120,000), your monthly payment jumps to approximately $5,200, requiring an income of $222,857.
• A 25% down payment ($200,000) reduces your monthly payment to $4,400, lowering the income requirement to $188,571.

Remember, putting down less than 20% on a jumbo loan often means higher interest rates and additional fees.

Credit Score Requirements for Jumbo Loans

Since $800,000 exceeds the 2026 conforming loan limit of $766,550 in most areas, you'll need a jumbo loan. Lenders typically require a minimum credit score of 700, but scores of 740+ get the best rates.

A 20-point difference in credit score can cost you $200+ monthly in higher interest payments.

Debt-to-Income Ratio Limits

Jumbo loans generally cap your debt-to-income ratio at 43%, though some lenders allow up to 45% with strong credit. If you have $2,000 in monthly debt payments (car loans, credit cards, student loans), you'll need a higher income to qualify.

With existing debt, aim for an income of $240,000 to $260,000 to stay within acceptable DTI limits.

Current Interest Rates and Monthly Payment Breakdown

As of 2026, jumbo loan rates average around 6.40%. On a $640,000 loan (after 20% down), your monthly breakdown looks like this:

• Principal and interest ($3,950)
• Property taxes ($1,000 estimated)
• Homeowners insurance ($600)
• Potential PMI or jumbo loan fees ($250)

This totals approximately $5,800 monthly.

Cash Reserves and Closing Costs

Lenders require 6-12 months of mortgage payments in reserves after closing. That's $28,800 to $57,600 in liquid assets beyond your down payment.

Closing costs typically run 2-5% of the purchase price ($16,000 to $40,000), bringing your total upfront cash need to $204,800 to $257,600.

Hidden Homeownership Costs

Beyond mortgage payments, budget for annual maintenance costs averaging 1-3% of home value ($8,000 to $24,000 yearly).

High-value home insurance can cost $3,000 to $8,000 annually, and property taxes vary widely by location but average $10,000 to $20,000 yearly on an $800,000 home.

Income Scenarios by Risk Tolerance

Conservative approach ($260,000 income): Keeps housing costs at 22% of income, leaving room for unexpected expenses and retirement savings.

Moderate approach ($240,000 income): Uses the standard 24% housing ratio with some financial cushion.

Aggressive approach ($220,000 income): Pushes closer to the 26% limit, requiring strict budgeting elsewhere.
