You just got the keys. Your hands are probably still shaking a little.
Somewhere between the champagne toast and the exhaustion of moving boxes, a quiet panic sets in: now what? If you’re wondering what you’re supposed to actually do in your first week as a homeowner, you’re not alone — and the good news is, it’s a shorter list than you think.
Quick Answer: In your first week as a new homeowner, you should change the locks, locate your main shutoff valves, set up utilities and homeowners insurance, file for your homestead exemption, test smoke and carbon monoxide detectors, save all closing documents, meet your neighbors, create a home maintenance binder, check the HVAC filter, and start an emergency repair fund. These tasks protect your safety, your finances, and your investment right from day one.
Buying a house feels overwhelming for almost everyone, even when it’s exciting. So let’s walk through exactly what matters this week — no fluff, no jargon, just the real stuff.
Why the First Week Matters More Than You Think
Here’s what most first time home buyers don’t realize: the first week sets the tone for how smoothly (or stressfully) your first year of homeownership goes.
Skip a step now, and it often turns into a bigger headache — or a bigger bill — later. According to the Consumer Financial Protection Bureau, new homeowners who understand their documents and systems early tend to catch costly issues faster than those who don’t.
So think of this week as laying the foundation. Not the concrete kind — the peace-of-mind kind.
The 10 Essential First-Week Homeowner Tasks
1. Change the Locks (Seriously, Do This First)
You have no idea how many spare keys exist for your new front door. Past owners, real estate agents, contractors, even a neighbor who used to water the plants — any of them could have a copy.
Rekeying a lock typically costs between $50 and $150 per door, and it’s one of the cheapest peace-of-mind purchases you’ll ever make. This is where many buyers make a costly mistake by assuming it’s “probably fine.” It’s not worth the risk.
2. Locate Your Main Shutoff Valves
Find your water shutoff valve, gas shutoff valve, and electrical breaker panel before you need them in an emergency. A burst pipe at 2 a.m. is not the time to start searching.
Take a photo of each location on your phone. Future-you will thank present-you.
3. Set Up Utilities and Homeowners Insurance
Confirm electricity, water, gas, internet, and trash service are active in your name. Most lenders also require proof of active homeowners insurance before closing, so this should already be moving — but double-check the policy is officially in effect.
Homeowners insurance typically costs around $1,700 to $2,600 per year on average in the U.S., though it varies widely by state and home value.
4. File for Your Homestead Exemption
Many states offer a homestead exemption, which can lower your property tax bill simply because the home is your primary residence. It’s often a short form, and the savings can be meaningful year after year.
Check your county tax assessor’s website for the deadline — some states require filing within the first few months of ownership.
5. Test Every Smoke and Carbon Monoxide Detector
Don’t assume the previous owner left working batteries. Test every detector in the house, and replace batteries if there’s any doubt.
The U.S. Fire Administration recommends testing smoke alarms monthly, but the first week is non-negotiable — this is basic safety, not a nice-to-have.
6. Save and Organize All Closing Documents
Your closing disclosure, deed, title insurance policy, and loan documents are important for taxes, refinancing, and resale down the road. Create a folder — physical or digital — and keep everything in one place.
According to the Department of Housing and Urban Development, buyers should keep these records for as long as they own the home, and often longer for tax purposes.
7. Meet Your Neighbors
This one feels small, but it matters more than people expect. Neighbors often know things about the house, the street, or the neighborhood that no inspection report will ever tell you.
A quick “hi, we just moved in” can turn into a lifelong friendship — or at least someone who’ll grab your mail when you’re away.
8. Create a Home Maintenance Binder or Digital Folder
Start tracking appliance manuals, warranty information, paint colors, and service contacts. This becomes priceless the first time your dishwasher breaks or you need to touch up a wall.
9. Check and Replace the HVAC Filter
A dirty filter makes your system work harder, which raises your energy bill and shortens the unit’s lifespan. It’s a five-minute task that can save real money.
Most filters should be replaced every one to three months, depending on the type.
10. Start (or Add to) an Emergency Repair Fund
Homeownership means you’re now your own landlord. There’s no one to call when the water heater dies except a plumber — and yourself.
Many financial experts suggest setting aside 1% of your home’s value each year for maintenance and surprise repairs. On a $350,000 home, that’s roughly $3,500 annually, or about $290 a month.
Your First-Week Action Plan, Step by Step
If you want a simple order to tackle everything, follow this:
- Change the locks on all exterior doors
- Locate and photograph your water, gas, and electrical shutoffs
- Confirm utilities are active and insurance is in effect
- Test every smoke and carbon monoxide detector
- Replace the HVAC filter
- File your homestead exemption paperwork
- Organize your closing documents in one folder
- Introduce yourself to at least one neighbor
- Set up a maintenance binder or digital note
- Move a small amount into a dedicated repair fund
Do these in order, and by day seven, you’ll feel like an actual homeowner — not just someone holding a very expensive set of keys.
A Real First-Week Story: Meet Jasmine
Jasmine closed on her first home, a small ranch-style house in Ohio, on a Friday. By Sunday night, she realized she had no idea where the water shutoff was — because her washing machine hose sprang a leak.
She spent 20 panicked minutes searching before finding it in the garage, half-hidden behind a shelf. Now, it’s the very first thing she shows anyone who house-sits for her.
Small task. Big lesson.
Common Mistakes New Homeowners Make in Week One
- Assuming the previous owner’s habits were safe — old batteries, expired fire extinguishers, and unlabeled breakers are more common than you’d think
- Losing closing documents in the chaos of moving boxes, then scrambling for them at tax time
- Skipping the homestead exemption deadline, missing out on real tax savings
- Spending the entire moving budget and leaving nothing for a first repair
- Not testing the HVAC system before the first hot or cold snap hits

| Homeowners insurance active | Immediate | $1,700–$2,600/yr | Loan requirement, protects investment |
| Homestead exemption | Within weeks | Free (filing) | Lowers property tax |

You’ve Got This
Here’s the truth: nobody feels fully ready their first week as a homeowner. That mix of excitement and “wait, is this really mine?” is completely normal.
But now you have a real plan instead of a vague sense of dread. Work through the list, take it one task at a time, and give yourself grace for the parts that feel unfamiliar.
This is exactly why so many people stay stuck renting longer than they planned — the unknown feels bigger than it actually is. You already did the hard part. You bought the house.
Now go find that water shutoff valve before you need it.
