Regular Home Expenses People Forget About

Most people would agree that buying a home is one of the (if not the) biggest purchases you’ll make in your lifetime. In early 2026, Redfin put the median home price in the US at $429,226. Undeniably, paying over $400,000 for something is a massive purchase, but the cost of home ownership doesn’t end there.

Maintenance, utilities, and insurance are only the beginning of home expenses. These items are often more than people expect, so research and look at actual numbers. Additionally, things like HOA special assessments, additional insurance coverage, and high deductibles increase costs. Even little things like light bulbs, touch-up paint, and batteries add to your budget.

Owning a home continues to generate expenses long after you pay off the mortgage. But not everyone thinks about these costs, especially first-time home buyers, and they can sneak up on you if you’re not prepared.

Taking A Closer Look At Overlooked Home Expenses

If you’re a homeowner or considering buying a house, you might find it insulting to hear something like, "You need to pay for utilities and maintenance." You get it. You’re responsible for everything when you own a home, from the landscaping to the light bulbs. You also know that the mortgage payment isn’t just principal and interest. You’re aware that you’ll have property taxes and insurance rolled up into your payment.

But that isn’t what this article is all about, because as you said, you already knew that. Instead, the information here is meant to prompt you to take a closer look at these expenses and how they could surprise you. As well, there are certain expenses tied to owning a home that you may not have thought about, or perhaps underestimated. Let this be a guide to helping you prepare for all the possibilities. Then, you can be in the best position possible when deciding on a huge investment such as buying a home.

A Clearer Idea Of The True Costs Of Home Maintenance

Knowing that you’re responsible for all of the home maintenance is a good start, but it’s also pretty vague. Unless you dig in a bit to get some information, you could go into home ownership greatly underestimating how much money you'll need to maintain a home. The general rule-of-thumb is to plan on spending one- to four-percent of your home’s value on maintenance.

If you buy a home worth $300,000, that means $3,000 to $12,000 a year goes toward repairs and upkeep. However, even that’s a pretty wide spread. To better plan, consider the age and condition of your home. Newer homes that are in good shape might require the one percent number, whereas a fixer-upper needs the four percent.

The Little Repairs Add Up

If you’re unsure, play it safe and aim for somewhere in the middle. Even homes in excellent condition will experience regular wear and tear throughout the year. For example, small repairs, like leaky faucets, a running toilet, or a broken light fixture, could add up to $500 a year. Call a plumber to tackle a simple problem, and you’ll pay another $75 to $150 on top of the repair costs for the service visit. It all adds up, so count everything.

Yard And Outdoor Costs

Taking care of your yard is an ongoing project that could run you anywhere from $200 to $600 or more a year if you take the DIY route. The larger your yard, the bigger your lawn care budget needs to be. If you opt to use a lawn service, these numbers rise dramatically. You may pay $50 to $100 per visit. Then there are additional considerations, such as tree trimming, sprinkler maintenance, pool care, and gardening.

And remember, these are just examples of ongoing needs. In addition, you need to think about the inevitable “unexpected” expenses. For example, a tree threatens to cause damage to your roof or foundation, and you need to hire someone to remove it. You could be looking at anywhere from $2,000 to over $10,000, depending on the tree and its location.

HVAC Maintenance

Even if the home you buy has a brand-new HVAC unit, you still need to pay for service every year. Ideally, you’ll have the unit serviced twice, once before the summer and once before the winter. These annual services usually run between $100 and $300. You also need to replace the air filters, which can cost anywhere from $50 to over $200 a year, depending on the size, type, and how often you need to replace them.

Beyond routine annual service, it’s also a good idea to get ducts cleaned every few years to remove dust and debris buildup. Duct cleaning can cost roughly $300 to $700. Like everything else, what you pay depends on the size, location, and condition of your home.

Regular Cleaning And Upkeep

When you own a home, keeping it clean isn’t just about dusting, mopping, and sweeping. Over time, things get dingy, and you’ll likely need to clean the gutters, pressure-wash the walkways and siding, and touch up the paint. Perhaps you have a chimney that requires routine cleaning. These things all add more money to your expense sheet.

You could pay anywhere from $300 to over $1,000 a year on routine cleaning and upkeep. These things may not seem like big expenses when you tackle them one at a time. However, step back and look at the big picture, and you can see how it all adds up pretty quickly.

Miscellaneous Items

Don’t forget about all of the little things you buy along the way, like light bulbs, batteries, tools, cleaning products, and decor upgrades. These things add to your costs, as small as they seem at the moment. You could spend $300 a year just on light bulbs. If you like to spruce up throw pillows and patio cushions yearly, you’re looking at another $300 to $1,000. Even changing the batteries in the smoke alarm and carbon monoxide detectors (which you should do yearly) takes money.

Pest Control

Pest control costs vary by location, as different areas are susceptible to different critters. But you can plan to spend around $300 to $600 per year on routine preventive services. In the South, it’s common to need a termite contract and regular, specialized termite treatments.

These can cost anywhere from $1,500 to over $6,000 for an initial treatment, and yearly upkeep can be around $150 to $300. If you end up with an infestation, there may be additional charges to handle the problem, depending on your contract terms. Then there are the extra costs for repairing any damage. 

Handling Utility Prices That Fluctuate

You know you have to pay utilities, and you may get a pretty good estimate from previous homeowners or your own experience. However, be prepared for fluctuating prices. Certain utilities spike in different months, and sometimes they catch people off guard. For example, if you have electric and natural gas, your electric bill may be significantly lower in the winter, maybe $75 a month. However, in the summer, it jumps up to $300 a month. Water usage also fluctuates throughout the year.

To better prepare for these fluctuations, look at a year’s worth of utility costs and divide them by 12 to get an average. Put this amount into a dedicated savings account each month and pay your utilities from that account. For example, if you add up all of your utilities and realize that in one year you spend $3,000, that’s an average of $250 a month. Start putting $250 a month into your utilities account, and set all your utilities to auto-draft from that account. Even if your utilities come to only $125 one month, you still put $250 a month into that account, so it grows. Then, when you have a higher month where utilities are $450, what you need is there, and your monthly budget isn’t thrown off kilter.

Insurance Gaps, HOA Fees, And Extra Coverage

Beyond the costs of property taxes and homeowners’ insurance, consider that these amounts typically go up every year. If you live in areas hit with a lot of claims, (think Florida and hurricanes), insurance rates can rise dramatically.

Extra Insurance And Deductibles

You may need additional coverage for wind and hail, floods, or earthquakes, depending on where your house is. You'll still need money to cover your insurance deductible, which could be $10,000 for some. (And if you have more than one type of coverage, you could be facing multiple deductibles for one incident.)

Many people opt for higher deductibles to lower their monthly premiums, and some policies, such as wind and hail, set the deductible as a percentage of the dwelling coverage. So if your deductible is 3% and your dwelling coverage is $400,000, you’re looking at $12,000.

Rising Property Taxes

Property taxes tend to go up each year. Additionally, some people who bought new-construction homes found their property taxes increased significantly after a year due to confusion over assessments. When they first bought the house, taxes were assessed only on the land. Once the home was factored into the equation, some people saw their taxes double or triple.

Surprise HOA Costs

If you live in an area with an HOA, you know you’ll have a monthly HOA fee. These fees can rise, but it’s extra charges you want to watch for, like special assessments, which aren’t always expected. For example, if the HOA’s clubhouse needs a new roof, the cost can show up as an increase in your monthly fees.

Staying Realistic About The Costs Of Home Ownership

If you’re not into math and you just want to keep it simple, plan to spend between $300 and $1,000 a month on your home (beyond the mortgage payment). If you’re in a small home with limited expenses and perhaps an HOA that takes care of exterior maintenance, you may fall closer to the bare minimum. (Of course, then you have HOA fees to factor in, too.)

A larger home will cost you more. To play it safe, plan on at least falling somewhere in the middle, around $600 to $700 a month for utilities, basic upkeep, and routine maintenance. However, it’s wise to build a buffer fund for large expenses, like a new roof or a busted water heater. These things are on top of your regular cleaning, repairs, etc.

Build A Buffer For Large Home Expenses

Break inevitable replacement costs into annual savings buckets to ease the burden when they hit. For example, a roof replacement can cost $8,000 to $30,000, and on average, you need a new roof every 20 to 30 years. Let’s say your new roof would cost $15,000 to replace in 20 years. Divide $15,000 by 20 to get $750. Now, divide $750 by 12 to get $62.50 a month.

Do the same for a new HVAC unit (about $250 a year savings), appliances (about $500 a year savings), etc. You would need about $125 per month to contribute to a dedicated house fund to cover these larger replacement costs. Some people use an emergency fund for these types of expenses, but you know these things are coming. A roof doesn’t last forever, water heaters bust after about 10 years, and so on.

Don’t Let Home Expenses Sneak Up On You

It’s all too easy to think of home expenses as the mortgage, maintenance, and utilities. But unless you hash out the numbers and set realistic costs based on research, you’re pulling random numbers out of the air. Little things add up, so you need to count them into the equation. Consider whether you’re tackling projects yourself or hiring professionals to help.

Expect things to fluctuate and rise over time. Plan for these fluctuations and increases, so you’re not caught off guard. Don’t underestimate home maintenance, and always expect the unexpected. When you do this, you’ll be in a better position to handle the expenses that are simply part of what it means to own a home.
