First 30 Days Homeowner Checklist: What Not to Skip

The locks, shutoffs, and detectors that matter more than furniture in week one, and what skipping them costs.

Cover of the HomeMath First 30 Days Homeowner Checklist

What's inside

  • A week-by-week roadmap — safety and security in week 1, utilities and maintenance setup in weeks 2–3, budget baseline in week 4
  • The exact reasons rekeying, garage codes, and shutoff locations matter more than furniture in week one
  • A maintenance cadence reference — monthly through every 5–10 years — so nothing gets missed after the calendar's built

3 key takeaways

  1. What should you do before you unpack a single box?

    Change every exterior lock and garage code, and locate your water, gas, and electrical shutoffs. Everyone who ever had a key still has one.

  2. What's the one habit that predicts long-term maintenance costs?

    Set up a dedicated maintenance savings account in week four — transfer 1% of your home's value divided by 12 each month, automated from day one.

  3. What should you check on your water heater in week one?

    Confirm the temperature is set to 120°F — above is a scalding risk, below is a Legionella risk — and check the pressure relief valve isn't corroded.
