What Costs Do People Forget When Buying a Home?

Closing costs

Buyer closing costs typically range from 2–5% of the home price and are due at the closing table — separate from and in addition to your down payment. On a $400,000 home, that is $8,000–$20,000 in cash you need available on closing day.

The major line items include the loan origination fee (typically 0.5–1% of the loan), appraisal fee ($400–$700), lender's title insurance, owner's title insurance, escrow and settlement fees, recording fees, prepaid interest, and prepaid insurance and property tax escrow. Use the Closing Costs Calculator to estimate your specific total.

Moving and setup costs

Buyers moving from an apartment to a house often underestimate how much it costs to furnish and equip a larger space. Moving costs for a local move average $1,000–$2,500. Long-distance moves can run $4,000–$10,000 or more.

Setup costs — new furniture, window treatments, landscaping, garage door openers, additional appliances — can easily total $5,000–$20,000 in the first year.

Maintenance and repairs

This is the most consistently underestimated cost category. The standard 1% rule suggests budgeting 1% of the home's value annually for maintenance. On a $400,000 home, that is $4,000 per year or $333 per month on average.

Maintenance costs are lumpy — small expenses most years, then a major expense like a roof replacement ($8,000–$15,000), HVAC system ($5,000–$10,000), or water heater ($800–$2,000) every several years. The 1% rule is a long-run average, not a monthly guarantee. Having a home maintenance reserve is essential.

Property tax surprises

Property taxes vary enormously by location — from under 0.5% in some Southern states to over 2% in Illinois, New Jersey, and New Hampshire. What buyers often miss is that property taxes can increase after a sale.

Many jurisdictions reassess property values when a home sells, often at the sale price. If the previous owner had a much lower assessed value (common in states with reassessment caps like California or New York), your tax bill can jump significantly after you purchase.

Utility cost increases

A larger home with more square footage, higher ceilings, older insulation, and a bigger yard typically costs more to heat, cool, and maintain than an apartment. Utilities including electricity, gas, water, and trash can add $200–$500/month more than apartment dwellers pay.

Ask the seller for 12 months of utility bills before closing. This is a reasonable request that most sellers will accommodate and can significantly affect your budget.

HOA fees and special assessments

Condominiums, townhouses, and many single-family home communities have HOAs with monthly fees ranging from $100 to over $1,000 depending on amenities and building condition. These fees are not optional and increase over time.

More dangerous than regular HOA fees are special assessments — one-time charges for major repairs that the HOA's reserve fund cannot cover. Before buying in an HOA, request the reserve fund study, meeting minutes, and financial statements. A poorly funded HOA is a serious financial liability.

Insurance surprises

Homeowners insurance premiums have risen sharply in many markets due to climate-related risks. In some coastal and wildfire-prone areas, insurance has become unavailable from standard carriers or costs several times the national average. Always get insurance quotes before closing — not after.

You may also need flood insurance (required by lenders in FEMA flood zones, not included in standard homeowners policies), earthquake insurance in seismic areas, or extended coverage for expensive personal property.

The cost of selling

Many buyers plan carefully for buying costs but forget that selling a home is also expensive. Seller costs typically include agent commissions (5–6% of sale price), transfer taxes, title fees, and often repairs and staging costs. On a $450,000 eventual sale price, selling costs could total $27,000–$36,000.

These selling costs are part of the true total cost of homeownership and must be factored into your rent vs buy comparison — which is exactly what our Rent vs Buy Calculator does.
