Your Home Costs More Than Your Mortgage (Here's the Real Number)

The Number Nobody Tells You Before You Buy
Your mortgage payment is $2,100 a month. Great. That's what you budgeted for. But somehow you're spending $3,800 a month on your house, and you can't figure out where the other $1,700 went.
Welcome to actual homeownership.
The mortgage is just the headline number. Underneath it is a long list of recurring costs that most first-time buyers don't fully account for — and that even experienced homeowners tend to underestimate. Let's lay it all out with real numbers so there are no surprises.
Introducing Your "Home Run Rate"
In business, your "burn rate" is how much cash you spend per month to keep the lights on. Your home has the same thing — let's call it your Home Run Rate. It's every dollar that leaves your account because you own a house, whether you see it or not.
Here's what goes into it:
The Full Monthly Breakdown
We'll use a $400,000 home as our baseline — close to the national median in 2026. These are averages; your numbers will vary by location, home size, and age.
1. Mortgage Payment (Principal + Interest): $2,100/month
Based on a $400,000 home with 10% down ($360,000 loan), 30-year fixed at 6.5%. This is the number everyone knows. It's also the one that tricks you into thinking it's the whole picture.
2. Property Tax: $415/month ($4,980/year)
The national average effective property tax rate is about 1.1% of assessed value, but this varies enormously. New Jersey averages 2.23%. Hawaii averages 0.32%. Texas has no state income tax but makes up for it with property taxes around 1.6–1.8%. On a $400,000 home, you're looking at anywhere from $130/month (Hawaii) to $740/month (New Jersey).
Property taxes also increase over time. Many homeowners see 3–5% annual increases, and reassessments after purchase can spike your bill.
3. Homeowner's Insurance: $185/month ($2,220/year)
The national average for homeowner's insurance has climbed significantly — up about 30% since 2020 due to climate-related claims. In states like Florida, Louisiana, and Texas, premiums can be 2–3x the national average. If you're in a flood zone, add another $800–$2,500/year for flood insurance.
4. PMI (Private Mortgage Insurance): $150/month
If you put less than 20% down, you're paying PMI until you reach 20% equity. On a $360,000 loan, PMI typically runs 0.5–1% of the loan amount annually. At 0.5%, that's $150/month. The good news: this one eventually goes away. The bad news: it can take 5–8 years to hit 20% equity depending on appreciation.
5. Utilities: $380/month
This one sneaks up on people, especially those coming from apartments where some utilities were included.
- Electricity: $160/month (national average, per EIA data). Ranges from $90 in mild climates to $250+ in hot states with heavy AC use.
- Natural gas: $70/month average. Heating-heavy states can push this to $150+ in winter.
- Water/sewer: $75/month average. This has been rising 3–5% annually as infrastructure ages.
- Trash collection: $35/month (if not included in property tax).
- Internet: $40–$80/month (yes, this is a utility now).
6. Maintenance and Repairs: $333/month ($4,000/year)
This is the big one that catches people off guard. The standard rule of thumb is to budget 1% of your home's value per year for maintenance and repairs. On a $400,000 home, that's $4,000/year or $333/month.
Some years you'll spend $500 total. Other years you'll drop $12,000 on a new HVAC system or $8,000 on plumbing. The 1% rule works as a long-term average, but only if you're actually setting the money aside. Think of it like a self-funded insurance policy for your house.
What eats this budget: HVAC service ($150–$300/year), water heater flushing ($100–$200), plumbing repairs ($200–$500 per incident), appliance repairs, gutter cleaning, caulking, deck maintenance, driveway sealing, and the thousand tiny things that break at the worst possible time.
7. Lawn Care and Landscaping: $150/month
If you mow your own lawn, you're "saving" money but spending 2–4 hours every week doing it. Professional lawn service runs $120–$250/month depending on lot size and services (mowing, edging, blowing, fertilization). Add seasonal costs: mulching ($200–$500/year), leaf removal ($200–$400/fall), and tree trimming ($300–$1,500 per tree).
8. Pest Control: $45/month ($540/year)
Quarterly pest control runs $100–$175 per treatment. In the South, this isn't optional — termite bonds alone cost $250–$400/year, and you don't want to skip that. Termite damage costs American homeowners an estimated $5 billion annually, and it's not covered by homeowner's insurance.
9. HOA Fees: $0–$400/month
About 40% of homes in the U.S. are in an HOA. Average dues are $250/month but range from $50 (basic neighborhood standards) to $500+ (communities with pools, gyms, gated entry). Condo HOAs can be even higher — $400–$800/month — because they cover building insurance, exterior maintenance, and common areas.
HOA fees also increase. Expect 3–8% annual increases. Special assessments (one-time charges for major repairs) can hit $1,000–$10,000+, usually with little warning.
10. House Cleaning: $130/month
If you hire cleaning help — and about 10% of U.S. households do regularly — expect $120–$250 per visit for a standard home, typically bi-weekly. Many homeowners start with monthly deep cleans ($150–$300 per session).
The Full Home Run Rate
Let's add it all up for our $400,000 baseline home:
- Mortgage (P&I): $2,100
- Property tax: $415
- Insurance: $185
- PMI: $150
- Utilities: $380
- Maintenance (1% rule): $333
- Lawn care: $150
- Pest control: $45
- HOA: $250 (if applicable)
- Cleaning (monthly): $130
Total Home Run Rate: $4,138/month (with HOA) or $3,888/month (without HOA)
That's 85–97% more than the mortgage payment alone. Nearly double.
And we haven't even included home improvement projects, furniture, or that fence your neighbor keeps hinting about.
The Costs People Forget
Beyond the regular monthly expenses, there are periodic and one-time costs that hit your bank account:
- HVAC replacement: $5,000–$12,000 every 15–20 years
- Roof replacement: $8,000–$25,000 every 20–30 years
- Water heater: $1,200–$3,500 every 10–15 years
- Appliance replacements: $500–$3,000 each, and a house has 5–8 major appliances
- Exterior paint: $3,000–$8,000 every 7–10 years
- Driveway resurfacing: $2,000–$5,000 every 15–20 years
- Plumbing or electrical emergencies: $500–$5,000 (it's always on a Sunday)
- Tree removal: $500–$2,500 per tree
If you amortize these big-ticket items, they add roughly $200–$400/month to your Home Run Rate on top of the 1% maintenance budget.
How to Calculate YOUR Home Run Rate
Here's a quick formula:
- Start with your actual mortgage payment (PITI — principal, interest, tax, insurance)
- Add your average monthly utilities (check last 12 months of bills)
- Add 1% of home value ÷ 12 for maintenance reserves
- Add recurring services (lawn, pest, cleaning, HOA)
- Add $200/month for big-ticket reserves (roof, HVAC, appliances)

Why This Matters (Beyond Budgeting)
For Home Buyers
If your mortgage pre-approval is $2,500/month, your actual housing cost is probably $4,000–$4,500/month. That's the number to use when deciding if you can afford a home. Lenders look at your mortgage-to-income ratio, not your total-housing-cost-to-income ratio. That's your job.
The general recommendation: keep your total Home Run Rate below 35% of gross household income. At $4,000/month, that means you need about $137,000/year in household income. At $3,500/month, you need about $120,000.
For Current Homeowners
If you're not setting aside money for maintenance and big-ticket replacements, you're essentially taking a loan from your future self. When the AC dies on a 98°F day, you'll either pay cash (from reserves you should have been building) or put it on a credit card at 24% interest. The 1% rule exists because houses always need work — it's not if, it's when.
For the Rent vs. Buy Debate
When people compare renting vs. buying, they usually compare rent to the mortgage payment. That's comparing apples to oranges. Your rent includes maintenance, insurance, property tax, and all the other costs your landlord has baked into your monthly check. The honest comparison is rent vs. your full Home Run Rate, minus the equity you're building.
How to Reduce Your Home Run Rate
A few practical strategies:
- Refinance when rates drop. Even a 0.5% rate reduction on a $360,000 loan saves $100+/month.
- Appeal your property tax assessment. About 30–40% of appeals result in a reduction. It's worth a few hours of work.
- Shop insurance annually. Rates vary wildly between carriers. Bundling with auto insurance saves 10–25%.
- Invest in energy efficiency. LED bulbs, smart thermostats, insulation, and sealing air leaks can cut utility bills 15–30%.
- DIY what you can. Changing HVAC filters, caulking, basic landscaping, and gutter cleaning are simple money-savers.
- Stay ahead of maintenance. A $200 annual HVAC tune-up prevents a $7,000 premature replacement. A $50 tube of caulk prevents a $3,000 water damage repair.
The Bright Side
This isn't meant to scare you away from homeownership. It's meant to help you plan for it honestly. The truth is:
- You're building equity with every mortgage payment (even if slowly at first)
- Home values have historically appreciated 3–5% annually over the long term
- Mortgage interest and property taxes are tax-deductible (if you itemize)
- You have complete control over your living space
- Fixed-rate mortgages mean your biggest expense is locked in while rents keep rising
Homeownership is still one of the most reliable wealth-building tools available. But only if you go in with eyes open and a budget that reflects reality — not just the number on your mortgage statement.
Frequently Asked Questions
Is the 1% rule accurate for newer homes?
For homes less than 10 years old, you can often get away with 0.5–0.75% annually. New systems and warranties reduce repair frequency. But after year 10, things start breaking more often — appliances, water heaters, the first round of exterior maintenance. The 1% rule is a lifetime average, and the later years subsidize the early ones.
How much should I have in savings before buying a home?
Beyond your down payment and closing costs, aim for an emergency fund of $10,000–$15,000 specifically for home-related expenses. This covers the gap between moving in and building your monthly maintenance reserves. The last thing you want is to drain your savings on the purchase and then have no buffer when the water heater dies three months later.
Does home age significantly affect costs?
Absolutely. Homes built before 1980 typically cost 20–40% more to maintain than newer homes. Older electrical, plumbing, and HVAC systems need more attention. Homes with galvanized steel pipes, aluminum wiring, or original single-pane windows carry higher ongoing costs. Factor this into your purchase decision — that charming 1960s ranch may have a significantly higher Home Run Rate than the number on paper.
Should I buy a home warranty?
Home warranties cost $400–$700/year and cover repairs to major systems and appliances with a $75–$125 service call fee. They're okay for the first 1–2 years of ownership when you don't know the condition of everything yet. Long-term, you're statistically better off putting that money into your maintenance reserves. The coverage limitations and exclusions in home warranty contracts are extensive — they frequently deny claims for "pre-existing conditions" or "lack of maintenance."
What's the most expensive hidden cost of homeownership?
Deferred maintenance. When homeowners skip or delay maintenance to save money short-term, they create much larger expenses long-term. Skipping gutter cleaning leads to foundation issues ($5,000–$15,000). Ignoring a small roof leak leads to mold remediation ($3,000–$10,000). Not servicing your HVAC leads to premature replacement ($5,000–$12,000). The cheapest home maintenance is the kind you do on schedule.
How do I track my Home Run Rate?
Create a dedicated spreadsheet or use a budgeting app with a "Home" category. Track every home-related expense for 12 months — you'll be surprised at the total. Include everything: mortgage, utilities, every trip to the hardware store, every service call, every bag of mulch. After a year, you'll have your real number, and you can budget accurately going forward.
