Income Needed for a $1 Million House: What San Diego Buyers Should Know

What Does It Actually Take to Buy a $1 Million Home?

A $1 million home is not an unusual purchase in San Diego. In fact, it is close to the median price in many neighborhoods throughout the county. That means a large share of local buyers need to understand exactly what kind of income is required to qualify for a mortgage at this price point, and what other factors lenders look at beyond your paycheck.

The short answer is that most buyers will need a gross annual household income of roughly $200,000 to $250,000 to comfortably qualify for a $1 million home purchase with a conventional loan. But that number shifts based on your down payment, your debt load, your credit score, and the loan program you use. This article breaks down how lenders calculate affordability and what you can do to put yourself in the best position possible.

How Lenders Measure What You Can Afford

Lenders do not simply look at your salary and approve or deny you. They use a formula called the debt-to-income ratio, or DTI, to figure out whether your monthly income is enough to cover your proposed mortgage payment plus any other recurring debts you already carry.

Here is how it works: your total monthly debt obligations, including the new mortgage payment, car loans, student loans, minimum credit card payments, and any other installment debts, are divided by your gross monthly income (before taxes). The result is your DTI ratio, expressed as a percentage.

Most conventional loan programs want to see a total DTI at or below 43 to 45 percent. Some loan programs allow up to 50 percent with compensating factors like strong credit and significant cash reserves. But the lower your DTI, the stronger your application looks.

Front-End vs. Back-End DTI

There are actually two DTI numbers lenders consider. The front-end DTI looks at your housing costs alone, principal, interest, property taxes, homeowner’s insurance, and HOA dues if applicable, divided by your gross monthly income. Lenders generally like this number to be at or below 28 to 31 percent, though conventional loans are more flexible than older FHA guidelines.

The back-end DTI adds up all monthly debt payments, not just housing. This is the number that gets the most attention in underwriting. Keeping your back-end DTI under 43 percent is a reasonable target for most buyers at this price point.

Running the Numbers on a $1 Million Purchase

Let’s look at a realistic scenario. Assume a buyer puts 20 percent down on a $1 million home. That means a $200,000 down payment and a $800,000 loan.

At a 7 percent interest rate on a 30-year fixed mortgage, the principal and interest payment alone comes to approximately $5,322 per month. Add California property taxes, which are assessed at roughly 1.1 to 1.25 percent of the purchase price annually, and you are adding another $917 to $1,042 per month. Homeowner’s insurance typically runs $150 to $300 per month for a home at this value. If the neighborhood has an HOA, that could add another $200 to $600 or more.

A reasonable estimate for total monthly housing costs, excluding HOA, lands between $6,400 and $6,700 per month. With an HOA, that can easily climb to $7,000 or higher.

Income Required Based on That Payment

If a lender wants your housing costs to stay at or below 31 percent of your gross monthly income, you would need a gross monthly income of at least $20,645 to $21,600 to support a $6,400 to $6,700 housing payment. That works out to approximately $248,000 to $259,000 per year in gross income, assuming you have very little other debt.

If you carry significant other debts, say, $1,000 per month in car payments and student loans, the income requirement climbs further. In that case, your total debt load of $7,400 to $7,700 per month at a 43 percent back-end DTI would require gross monthly income of about $17,200 to $17,900, or roughly $207,000 to $215,000 annually. But at the 31 percent front-end limit, you still need the full income figure just for housing. The binding constraint depends on which ratio your lender uses more strictly.

Bottom line: plan on needing somewhere between $200,000 and $260,000 in annual gross income for a $1 million purchase, with the higher end applying when you have other debts or make a smaller down payment.

How the Down Payment Changes the Math

Putting 20 percent down is the most common benchmark discussed, but it is not the only option. A larger down payment reduces your loan amount and monthly payment, which lowers the income you need to qualify. A smaller down payment does the opposite, and may also trigger additional costs.

Putting Less Than 20 Percent Down

On a conventional loan, putting less than 20 percent down means you will need to pay private mortgage insurance (PMI). PMI is an additional monthly cost that protects the lender if you default, and it typically runs between 0.5 and 1.5 percent of the loan amount annually. On an $850,000 loan (10 percent down), that adds $354 to $1,063 per month to your housing cost, which pushes the required income even higher.

On a $1 million purchase with 10 percent down ($100,000 down, $900,000 loan at 7 percent), your principal and interest payment rises to approximately $5,987 per month. Add taxes, insurance, and PMI, and total monthly housing costs could easily reach $7,500 to $8,000 per month. That would require gross annual income in the range of $290,000 to $310,000 assuming a 31 percent front-end guideline.

Putting More Than 20 Percent Down

If you can put 25 or 30 percent down, the loan amount drops significantly. On a 25 percent down purchase ($250,000 down, $750,000 loan), your principal and interest at 7 percent drops to about $4,990 per month. Total housing costs come down to roughly $6,000 to $6,300 per month, reducing the income requirement to approximately $230,000 to $240,000 annually. A larger down payment also strengthens your file and may help you qualify for better rate pricing.

The Role of Credit Score

Your credit score affects not just whether you qualify, but what interest rate you receive. Even a small difference in rate has a big impact on payment at loan amounts this large.

Consider the difference between a 6.75 percent rate and a 7.25 percent rate on an $800,000 loan. At 6.75 percent, the principal and interest payment is approximately $5,190 per month. At 7.25 percent, it jumps to about $5,462 per month, a difference of $272 per month, or $3,264 per year. Over 30 years, that is nearly $98,000 more paid in interest.

To qualify for the most competitive rates on a jumbo or high-balance loan at this price point, most lenders want to see a credit score of 720 or higher. Scores above 740 or 760 tend to unlock the best pricing. If your score is in the 680 to 700 range, you may still qualify, but expect a higher rate and potentially stricter DTI requirements.

Jumbo Loans vs. Conforming Loans in California

One thing California buyers need to understand is how loan limits work at this price point. The federal government sets conforming loan limits each year, these are the maximum loan amounts that Fannie Mae and Freddie Mac will purchase. In most of San Diego County, the 2024 conforming loan limit for a single-family home is $1,006,250, which means some $1 million purchases may fall within conforming limits depending on your down payment.

If your loan amount stays at or below $1,006,250, you can use a standard conventional conforming loan, which tends to have more flexible guidelines than jumbo products. If your loan exceeds that limit, you are in jumbo loan territory. Jumbo loans are held by the lender rather than sold to Fannie Mae or Freddie Mac, so each lender sets its own guidelines. Jumbo products typically require stronger credit, higher reserves, and stricter DTI limits.

For many San Diego buyers purchasing at $1 million, a 20 percent down payment results in an $800,000 loan, well within conforming limits. But buyers putting only 10 percent down would have a $900,000 loan, which is also within the conforming limit for San Diego County. This is an important distinction because conforming loans are generally easier to qualify for and often carry slightly better rates than jumbo products.

What Counts as Income?

When lenders calculate your qualifying income, they do not just look at base salary. They consider all verifiable, stable income sources, but they have specific rules for each type.

W-2 Employment Income

If you are a salaried employee, your base pay is straightforward. Overtime, bonuses, and commissions can also be counted, but the lender will typically average them over a two-year period and require that they appear consistently on your tax returns and pay stubs. You cannot simply show a large one-time bonus and expect it to boost your qualifying income unless there is a clear two-year history of receiving it.

Self-Employment Income

Self-employed buyers often run into complications here. Lenders use your net income after business deductions as shown on your federal tax returns, not your gross revenue. If you write off significant expenses, your qualifying income may be much lower than what you actually bring home. Some lenders offer bank statement loan programs that allow self-employed buyers to document income using 12 or 24 months of bank deposits rather than tax returns, though these loans often come with higher interest rates.

Investment, Rental, and Retirement Income

Rental income from investment properties can count, typically at 75 percent of the gross rent to account for vacancy and expenses. Retirement income, Social Security, and pension payments can all be used. Investment distributions and capital gains income can count in some cases if they have a history and are expected to continue. Every income source has its own documentation requirements, so it pays to lay everything out clearly with your loan officer from the start.

Reserves: The Overlooked Requirement

Many buyers focus entirely on the down payment and forget about cash reserves. Reserves are funds you have left over after closing, money sitting in a savings, checking, or retirement account. Lenders want to know you have a financial cushion in case something goes wrong.

For a conforming loan, reserves requirements vary but can range from two to six months of housing payments. For a jumbo loan, lenders may require six to twelve months of reserves. On a $1 million purchase, six months of housing payments at $6,500 per month equals $39,000 in required reserves, in addition to your $200,000 down payment and closing costs.

Closing costs on a $1 million purchase in California typically run between 1 and 2 percent of the purchase price, or $10,000 to $20,000, depending on whether you pay discount points, prepay HOA dues, or negotiate seller credits. Total cash needed to close, including down payment and closing costs, can easily reach $210,000 to $225,000, and then you still need reserves on top of that.

Common Mistakes Buyers Make at This Price Point

At a $1 million purchase price, the stakes are high and the margin for error is narrow. Here are the mistakes that come up most often.

• Underestimating property taxes. California’s base property tax rate is 1 percent, but Mello-Roos assessments and other special taxes can push the effective rate to 1.25 percent or higher in many San Diego communities, especially newer developments.
• Ignoring HOA dues. HOA dues are included in your DTI calculation. A $500 monthly HOA on a $1 million condo can add meaningfully to your required income.
• Opening new credit before closing. A new car loan or credit card application right before closing can change your DTI and potentially kill the deal.
• Counting on bonus income that has not been verified. Lenders require a two-year history for variable income. If you just started a new job with a higher salary, that income may qualify, but recent bonuses from a prior employer may not.
• Not shopping loan programs. At the $1 million price point in San Diego, depending on your down payment, you may qualify for conforming, high-balance conforming, or jumbo products. Each has different guidelines and rates. Getting multiple quotes can save you a meaningful amount over the life of the loan.

What If Your Income Falls Short?

If your income is close but not quite there, you have a few options worth exploring before you give up on a $1 million purchase.

First, consider a co-borrower. Adding a spouse, domestic partner, or family member to the loan combines your incomes, which can significantly improve your DTI ratio. Both borrowers’ credit scores and debts will also be considered, so this works best when both parties have solid credit profiles.

Second, look at whether paying down existing debts could help. Eliminating a car payment of $500 per month improves your monthly debt picture by $500, which at a 43 percent DTI cap effectively lets you qualify for about $1,163 more in monthly housing costs, which translates to a substantially larger loan.

Third, a larger down payment reduces the loan amount and monthly payment. If a family gift or asset sale can boost your down payment from 10 to 20 percent, it may be enough to bring your DTI into qualifying range without any change to your income.

Real-World Context for San Diego Buyers

San Diego consistently ranks among the most expensive housing markets in the country, and a $1 million purchase is a realistic scenario for a wide range of property types, from a three-bedroom home in a coastal neighborhood to a newer townhome or condo in a suburban community. Many buyers at this price point are dual-income households combining two professional salaries, or long-time homeowners using equity from a prior sale to boost their down payment.

The good news is that San Diego’s high-cost designation means conforming loan limits are elevated, giving buyers access to conventional loan products even at significant loan amounts. The tighter guideline landscape of jumbo loans applies to fewer buyers than it would in a lower-cost county.

The most important step any serious buyer can take is getting pre-approved before shopping, not after. A pre-approval at this level requires documented income, full credit review, and a realistic look at your full financial picture. It also lets you move quickly and credibly when the right home comes along, which matters in a competitive market.

Frequently Asked Questions

Can two people combine incomes to qualify for a $1 million home?

Yes, and this is one of the most common ways buyers at this price point qualify. When you apply for a mortgage with a co-borrower, the lender considers both borrowers’ incomes together, which reduces the DTI ratio and improves your qualifying strength. Both borrowers’ debts and credit scores are also factored in, so it works best when both parties have manageable debt and solid credit. Two borrowers each earning $120,000 per year, for example, would have a combined gross income of $240,000, well within the typical qualifying range for a $1 million purchase.

Does the interest rate really make that big a difference on a $1 million home?

At loan amounts this large, even a quarter-point difference in rate has a noticeable impact. On an $800,000 loan, the difference between a 6.75 percent and 7.25 percent rate is roughly $272 per month. Over the life of a 30-year loan, that adds up to nearly $98,000 in additional interest. This is why credit score matters so much at this price point, borrowers with stronger profiles qualify for better rates, which can mean real money saved over time. It also makes it worth taking the time to shop loan programs and lenders rather than accepting the first offer you receive.

Are there loan programs that make it easier to buy a $1 million home in California?

Because San Diego is a high-cost area, conforming loan limits are elevated, up to $1,006,250 for a single-family home in 2024. This means many buyers can use conventional conforming loans rather than jumbo products, even at the $1 million price point. Conforming loans generally have more flexible DTI guidelines and competitive rates. For buyers who need a larger loan amount, jumbo products are available but come with stricter reserve and credit requirements. Some lenders also offer bank statement loans for self-employed buyers who cannot document income through traditional tax returns. The right program depends on your income type, credit profile, down payment, and overall financial picture.
