Other factors that affect how much home you can afford

Income isn’t the only factor that goes into whether you can afford a mortgage on an $800k house. Here are some additional elements to keep in mind:

— Interest rate: This is one of the biggest components in how affordable a mortgage feels. Even a tiny difference can move your monthly payment and add up over the life of the loan.

— Credit score: Your credit score plays a big role in landing a favorable interest rate. Especially for conventional loans, lenders like to see a minimum of 620.

— Debt-to-income (DTI) ratio: This metric compares your gross monthly income to your monthly debt payments. Many lenders prefer a maximum debt-to-income ratio of 43%, but your mileage may vary.

— Property taxes: These can look very different depending on the state you’re buying property in. Rates range from just 0.32% in Hawaii all the way up to 1.77% in New Jersey.

— Down payment: The bigger the down payment, the smaller your initial loan, which lowers monthly costs. It also makes you more attractive to lenders since it signals you’re less likely to default.

Lender and borrower budgeting rules

Each lender follows a set of guidelines to decide who qualifies for a mortgage and what interest rates to offer. These include:

— The 35/45 model: This metric compares your gross and net (after-tax) income. It recommends that your total debt payments, including your mortgage and personal loans, shouldn’t exceed 35% of your gross income or 45% of your net income.

— The 25% after-tax rule: This guideline focuses on mortgage payments alone. It suggests using no more than 25% of your net income for mortgage payments.

How much is a down payment on an $800,000 house?

For any mortgage, your down payment size depends on the lender and the type of loan. Here are the most common ways buyers finance an $800,000 home, from zero-down options to loans that require an up-front payment.

No down payment on an $800k mortgage

Two government programs offer mortgages with zero down: Department of Veterans Affairs (VA) loans and United States Department of Agriculture (USDA) loans.

VA loans are only available to eligible active-duty service members, veterans, and surviving spouses of veterans. USDA loans offer zero-down options and flexible credit requirements for low-to-moderate income buyers. To qualify, you must live in an approved rural area and have a moderate income below USDA-set limits.

A small down payment on an $800k house

Federal Housing Administration (FHA) loans offer low down payments and flexible credit criteria. With a credit score of 580 or higher, you can put down as little as 3.5%. If you’re in the 500–579 range, however, you’ll need to put down 10%.

Conventional loans, by comparison, offer more flexibility than many people realize. You don’t need to put down 20% — some lenders accept as low as 3% if you have a strong credit profile. There’s one hitch: If you put down less than 20% on a conventional mortgage, you’ll have to pay private mortgage insurance (PMI) until your equity passes that threshold.

$800k house mortgage affordability scenarios

Let’s take a look at a few different scenarios you may face:

— A 30-year fixed-rate mortgage keeps the interest rate the same for the life of the loan. It spreads payments over 30 years to lower monthly costs, but you pay more interest overall.

— A 15-year fixed-rate mortgage maintains the same interest rate for 15 years, but the shorter term means higher monthly payments.

— An adjustable-rate mortgage starts with a fixed interest rate for a set period (e.g., five, seven, or 10 years) before adjusting annually. Initial payments will be lower, but you might face higher costs in the future.

FAQ

How much should you make to buy an $800k house?

You may qualify for an $800,000 mortgage if your income falls between $200,000 and $260,000. But income alone doesn’t determine affordability. Many other factors, like your down payment, credit score, and mortgage interest rate, influence how much you can afford.

What’s a common rule of thumb for the proportion of income spent on housing payments?

Determining how much to afford an $800k house can be tricky. The 28/36 rule makes it easier to estimate:

— Housing costs: Your mortgage payments, including property taxes and insurance, should be no more than 28% of your gross income.

— Total debt payments: Your mortgage plus other debt payments should make up no more than 36% of your gross income.
