The Hidden Costs of Buying a Home

And of homeownership
Kaila Henry  |  June 27, 2026

The excitement of purchasing your first home is unmatched. You see the list price, calculate the principal and interest on a mortgage calculator, and think, "Perfect, I can afford this!"

However, there can be a difference between what you are approved to borrow and what it actually costs to live in a home. Beyond your standard mortgage payment, a wave of overlooked expenses can quickly sneak up on you. Nationally, the average U.S. homeowner faces roughly $16,000 to $21,400 per year in hidden homeownership costs (according to Zillow). 

Whether you are looking for a home in the mountains of Montana or anywhere else across the country, here is a breakdown of the hidden costs of home purchase and ownership to consider as you search the market. 

1. The Hidden Costs at Closing and Day One

Before you get the keys, several transaction-based and immediate costs enter the picture.

  • Due Diligence and Inspections: During your inspection period, I highly recommend having a home inspection.  This will be an out-of-pocket expense due before closing & quite possibly some of the best money spent.  The inspector will go over the home from exterior to interior, attic to crawlspace and evaluate the systems of the home, life expectancy of major systems as well as, identify cosmetic defects.  Costs of inspections can vary greatly, mostly depending on home size, location, and, systems evaluated (septic, well, out buildings etc).  
  • Escrow & Reserve Funds: At closing, your loan officer will require you to fund an escrow account. This account holds several months' worth of property taxes and homeowners insurance in advance to ensure those bills are covered for a bit.  This should not be a surprise at closing, a good lender will be discussing these costs up front with you.
  • New Construction Considerations: We aren't just talking about buying a new couch. Many buyers forget that unless explicitly stated in the contract, new homes rarely come with window coverings or blinds. Buying custom blinds for a whole house can easily cost thousands of dollars.  Landscaping & washer/dryer units can also be a wild card so make sure you're clear about what the builder is offering, or be sure to include specifics into your purchase contract. 

2. Fluctuating Overhead Costs: Taxes, Insurance,HOAs & Special Assessments

Your monthly mortgage payment isn't set in stone. Because of fluctuating local variables, your escrowed expenses can shift based on external factors. 

Property Taxes & Homeowners Insurance

Taxes vary significantly by location. Furthermore, insurance companies have become incredibly touchy about regional risks. If you are buying a historic home, or a property located in a floodplain or wildfire zone, be aware and prepared for insurance costs to change over time.  

Homeowners Association (HOA) Fees

If your neighborhood has an HOA, those monthly or quarterly dues are mandatory.  Be sure to factor in any HOA dues while evaluating the affordability of the property and chat with your realtor & lender to understand the health of the association (we don't want any large special assessments to sneak up on us). 

3. The Unforgiving Cost of Maintenance and DIY

One of the biggest shocks for first-time buyers is that you are now the landlord. If a toilet leaks or an appliance fails, there is no one to call but a professional (or YouTube for a possible fix).

The Gold Standard Rule of Thumb: Experts recommend setting aside 1% to 4% of your home's total value annually strictly for maintenance and repairs. For a $500,000 home, that means budgeting $5,000 to $20,000 a year for upkeep.  This number can change depending on the condition of the home you're purchasing. 

  • Appliances and Mechanicals: Items like water heaters, refrigerators, and HVAC units have general life expectancies. If they fail, replacing them can cost a few thousand dollars. Even routine items like replacing your furnace and/or water filters every few months can add up. 
  • Landscaping and Fencing: Moving into a new build? It might look complete, but front or backyard landscaping can be left out of the base price. Throwing down sod, planting trees, or installing a fence for a pet can shock your bank account.

4. Rural vs. Urban Utility Realities

Where your home is located changes the nature of your operational costs.

Expense Category

Urban / Suburban Communities

Rural / Mountain Properties

Trash & Utilities

Often bundled into a simple city bill.

May require private haulers or separate contracts.

Water / Sewer

Standard municipal water meters.

Well maintenance and septic system pumping/repairs.

Infrastructure

City-maintained paved streets.

Private dirt roads requiring shared maintenance or split costs.

Winter Upkeep

Public snowplows take care of the main roads.

Snow removal equipment or hiring a plow guy for long driveways.

Pro Tip for First-Time Buyers

While working with your real estate agent and lender, present a realistic budget.  We're here to help you make informed decisions & our advice is only as good as the information we have from you.  Ask the seller for historical utility bills and verify if any upcoming HOA special assessments are on the horizon. After closing start to build a cash reserve over time so when maintenance or repair items arise, you have a set fund to pull from.  Keeping up with maintenance items will payoff in the long run so don't let small projects pile up. 

As always, I'm happy to be a resource and guide as you navigate purchasing your next property or evaluating what items need to be repaired before bringing your home to market.
