Unexpected Costs of Buying a Home (and How to Budget for Them)

Lailan Bento July 9, 2026


By Lailan Bento

When you're budgeting to buy a home, it's easy to focus entirely on the down payment and monthly mortgage. But the truth is that homeownership comes with a number of additional costs, some upfront and some ongoing, that can catch buyers off guard. As a Kona real estate agent, I believe an informed buyer is a confident buyer. Here are the unexpected costs of buying a home and how to budget for them.

Key Takeaways

  • Closing costs typically add 2 to 5 percent of the purchase price on top of your down payment
  • Ongoing costs like maintenance, insurance, and taxes require careful budgeting
  • Hawaii-specific factors like flood zones and HOA fees deserve special attention
  • Building an emergency buffer protects you from post-purchase financial stress

Upfront Costs Beyond the Down Payment

Most of a buyer's surprise expenses show up at closing. Beyond your down payment, there are several fees required to finalize the purchase, and they add up quickly.

Closing Costs and Upfront Expenses

What to plan for before closing:

  • Closing costs — these typically range from 2 to 5 percent of the purchase price, covering loan fees, title and escrow, and more; on a higher-priced Hawaii home, this is a significant sum
  • Home inspection — usually the buyer's responsibility, typically ranging from a few hundred dollars, and worth every penny
  • Earnest money — a good-faith deposit, often 1 to 3 percent of the price, which applies toward your costs at closing
  • Prepaid items — you may need to prepay portions of property taxes and homeowner's insurance at closing

Ongoing Costs of Homeownership

Once you own the home, a new set of recurring costs begins. Many first-time buyers underestimate these, so planning ahead is essential to comfortable homeownership.

Recurring Expenses to Budget For

The ongoing costs that matter:

  • Property taxes — these are an ongoing expense that can adjust over time, so factor them into your long-term budget
  • Homeowner's insurance — a required cost, and in Hawaii, you'll want to understand coverage for specific risks in your area
  • Maintenance and repairs — a common guideline is to budget roughly 1 to 2 percent of your home's value annually for upkeep
  • Utilities — often higher than buyers expect, especially when moving from a smaller space; factor in electricity, water, and more

Hawaii-Specific Considerations

Buying a home in Hawaii comes with a few unique cost factors that mainland buyers, and even local buyers, should keep in mind. Being aware of these helps you avoid surprises.

Costs Unique to the Islands

What to watch for in Hawaii:

  • Flood and lava zones — depending on the property's location, you may need specific insurance coverage, so understand the zone designations before you buy
  • HOA fees — if the property is in a community or condo association, factor in monthly dues, and be aware of the potential for special assessments
  • Higher insurance costs — insurance premiums, particularly for condos, have been rising and should be quoted early
  • Solar considerations — if a home has solar, understand whether it's owned or leased, as this affects your costs

How to Budget Smartly

The good news is that none of these costs are unmanageable when you plan for them. The key is building a realistic budget that goes beyond the purchase price. Start by setting aside at least 2 percent of the home's price for upfront costs beyond your down payment. Then, build a monthly budget that includes your mortgage plus taxes, insurance, maintenance, utilities, and any HOA fees. Perhaps most importantly, maintain an emergency buffer after closing. Many buyers spend most of their savings on the down payment and closing, leaving little cushion, but homeownership often brings unexpected expenses soon after moving in. A financial safety net keeps those surprises from becoming stressful.

FAQs

How much should I budget for closing costs in Hawaii?

Closing costs typically range from 2 to 5 percent of the purchase price. On a Hawaii home, given the higher price points, this can be substantial, so it's important to plan for it early. Your lender can provide a detailed estimate, and in some cases certain costs may be negotiable or shared with the seller.

What's the most commonly overlooked cost of buying a home?

Ongoing maintenance and repairs are among the most overlooked. Unlike renting, homeowners are responsible for all upkeep, and experts generally recommend budgeting about 1 to 2 percent of the home's value annually. Property taxes, insurance, and potential HOA special assessments are also frequently underestimated by first-time buyers.

How much of an emergency fund should I keep after buying?

While it varies by your situation, keeping a buffer of several months of expenses after closing is wise. Homeownership often brings unexpected costs soon after moving in, from repairs to appliance replacements. Avoid draining all your savings on the down payment and closing, so you have a cushion for the surprises that inevitably come.
