How to Calculate True Cost of Homeownership Beyond the Listing Price

The listing price is only the start. Owning a home comes with costs that arrive every month and every year, and some that arrive all at once. Adding them up before you buy shows what you can really afford. This is general information, not financial advice.

Upfront costs

• Down payment: often 3% to 20% of the price, depending on the loan.
• Closing costs: lender fees, title insurance, appraisal and taxes, commonly 2% to 5% of the loan amount.
• Inspection: paid before you commit.
• Moving and setting up: movers, furniture, appliances, window coverings.

Monthly costs

• Principal and interest: the loan payment itself.
• Property taxes: vary widely by state and county. Check the county's rate, not the seller's current bill, which may reflect older assessments or exemptions.
• Homeowners insurance: rising fast in areas with storm or wildfire risk. Get quotes before making an offer.
• Mortgage insurance (PMI): usually required on conventional loans with less than 20% down.
• HOA fees: common for condos and planned communities, and they can rise or come with special assessments.
• Utilities: often higher than renting, especially in a bigger or older home.

Maintenance and repairs

A common rule of thumb is to budget 1% to 4% of the home's value each year for maintenance, more for older homes. Roofs, water heaters, heating systems and appliances all wear out on their own schedule.

A worked example

These numbers are assumptions to show the math, not typical figures for any area. A $400,000 home with 20% down:

• Loan of $320,000 at 6.5% for 30 years: about $2,023 a month in principal and interest.
• Property tax at 1.1% a year: about $367 a month.
• Insurance at $1,800 a year: $150 a month.
• Maintenance at 1% a year: about $333 a month.

Total: about $2,873 a month, over 40% more than the loan payment alone, before utilities or HOA fees. Run your own numbers with the mortgage calculator with taxes and insurance.

Compare homes fairly

Price per square foot helps compare homes of different sizes, but a cheaper home with a high HOA fee or an old roof can cost more to own. Look at the full monthly cost. Zillow Price/SqFt adds a price per square foot badge to listing cards on Zillow, and Zillow's own listing pages show an estimated monthly payment you can adjust. See condos vs houses.

Don't forget

• An emergency fund for repairs, separate from your down payment.
• Selling costs later, such as agent commissions and closing fees.
• The time you'll spend on upkeep.
