Cost of Owning

The True Monthly Cost of Owning a Home (Beyond the Mortgage)

The payment in a mortgage ad is usually just principal and interest. The real monthly cost of owning a home adds property tax, insurance, mortgage insurance, HOA dues, utilities and money set aside for repairs. On a $400,000 home bought with 10% down at 6.5%, principal and interest come to about $2,275, but the full monthly cost is closer to $3,675, roughly 60% more.

The seven costs of owning

1. Principal and interest

The loan payment itself. On a fixed-rate loan it stays the same for the life of the loan. Early on, most of it is interest: in the first month of a $360,000 loan at 6.5%, $1,950 of the $2,275 payment is interest and only about $325 reduces the balance.

2. Property tax

Usually paid monthly through your lender’s escrow account. It depends on your home’s assessed value and the combined local rate, and it can rise even when your loan payment doesn’t. Effective rates differ widely between states and even between neighboring towns. Our guide to how property tax is calculated explains the formula.

3. Homeowners insurance

Lenders require it, and it is also usually paid through escrow. Premiums depend heavily on location, the age of the roof, local weather risks and your claims history. In areas exposed to hurricanes, wildfire or hail, premiums have risen quickly in recent years. Get a real quote for the specific address before you make an offer, because a national average can be far off.

Standard policies don’t cover flood damage. If the home is in a high-risk flood zone (a zone starting with A or V on FEMA’s maps) and the loan comes from a federally regulated lender or a government-backed program, the lender will require separate flood insurance, and even outside a mapped zone it can be worth pricing.

4. Private mortgage insurance (PMI)

On a conventional loan with less than 20% down, you’ll usually pay PMI. It protects the lender, not you. The cost depends on your credit score and down payment; our example uses 0.5% of the loan per year. The good news is that it ends: under the federal Homeowners Protection Act you can ask in writing to cancel it once your balance reaches 80% of the home’s original value (on schedule or sooner through extra payments), if you’re current, have a good payment history and the home hasn’t lost value. It must end automatically when the balance is scheduled to reach 78%. FHA mortgage insurance and the fees on VA and USDA loans follow different rules. See how to get rid of PMI for the details.

5. HOA or condo fees

Common in condos, townhouses and newer subdivisions. Fees can range from a small yearly charge to several hundred dollars a month, and associations can raise them or levy special assessments for big repairs. Ask for the association’s budget and reserve study before you buy.

6. Maintenance and repairs

The cost most first-time buyers underestimate. A common planning rule is to set aside 1% to 2% of the home’s value each year, more for older homes. Repairs don’t arrive monthly: you may spend little for two years and then replace a roof or a furnace. Saving a fixed amount each month smooths that out.

7. Utilities

Electricity, gas, water, sewer, trash and internet. A house is often larger than the apartment you’re leaving, and some costs a landlord used to cover (water, trash) become yours. Ask the seller or the utility companies for the last 12 months of bills for the address. Our example assumes $400 a month; your number may be very different.

Worked example: $400,000 home, 10% down

About 38% of the true cost is invisible in a typical “monthly payment” quote.

Costs that change over time

• Taxes and insurance rise. Your escrow payment is recalculated every year, so the total payment on a fixed-rate loan can still go up.
• PMI goes away. Once it’s removed, your payment drops.
• Maintenance grows with age. Systems wear out on their own schedule: water heaters, roofs, HVAC.
• Interest shrinks, principal grows. The payment stays the same, but more of it builds equity each year.

How to estimate your own number

1. Get a loan estimate or use the rate a lender quotes you.
2. Look up the property’s current tax bill on the county website. Don’t use the seller’s bill if they have exemptions you won’t get.
3. Get an insurance quote for the address.
4. Ask for HOA documents and 12 months of utility bills.
5. Pick a maintenance percentage based on the home’s age and condition.
