First-Year Move-In Budget Worksheet: Beyond the Mortgage

The other 40 line items, from prepaid interest to lawn gear, most buyers forget to budget for.

Cover of the HomeMath First-Year Move-In Budget Worksheet

What's inside

  • A three-part budget — one-time closing costs, first-year setup costs, and annual recurring costs — with real dollar ranges on every line
  • The 1% rule explained in actual dollars, not just percentage, on a $400,000 home
  • 25+ line items most buyers forget to budget for, from prepaid interest to lawn equipment

3 key takeaways

  1. How much do first-time buyers typically underestimate their true first-year cost by?

    $15,000–$25,000. This worksheet exists so that gap doesn't hit as a surprise.

  2. What's the 1% rule, in real dollars?

    Set aside 1% of your home's purchase price per year for maintenance — not per month. On a $400,000 home, that's $333/month, automated the day your mortgage payment clears.

  3. What costs hit in the first 90 days that most buyers forget?

    Immediate repairs from the inspection report ($2,000–$8,000), lock rekeying ($200–$500), and specialist inspections like sewer scope or radon ($150–$500 each).
