First-Time Home Buyer Checklist After Closing: What to Do in Your First 30 Days

Closing day is the day all the paperwork disappears and you're handed a set of keys. It's the moment you've been working toward for months. And then you're standing outside your new front door, keys in hand, realizing you have no idea what to do first.

For first-time buyers especially, the transition from "buyer" to "homeowner" happens faster than expected, and the to-do list on the other side of closing is longer than most people anticipate. This checklist covers everything you need to do after closing, organized by urgency — from the first hour through the first thirty days.

Day One: Before You Unpack Anything

There are four things that should happen before you touch a single box.

Rekey or replace the locks. This is the most important item on this list, and the most commonly skipped. You do not know who has a key to your new house. The sellers may have given copies to a cleaning service, a contractor, neighbors, family members, or prior tenants. A locksmith can rekey every lock in an average house for $150–$250 in an hour. Do this before your belongings are inside.

Locate the main shutoffs. Walk through the house and find:

• The main water shutoff valve (usually in the basement, utility room, or crawl space near where the water line enters the house)
• The gas shutoff (at the meter, outside)
• The main electrical panel (circuit breakers)

In an emergency — a burst pipe, a gas smell, an electrical problem — not knowing where these are can turn a manageable situation into a serious one. Find them now, before you need them.

Test smoke and carbon monoxide detectors. Press the test button on every detector. Replace the batteries in all of them while you're at it — it takes ten minutes and covers a genuine safety risk. If any detector is more than 10 years old (check the manufacture date on the back), replace the unit.

Change the garage code. If your home has a garage door opener, reset the keypad code. If any neighbors have a remote programmed to your garage (a common seller courtesy), those remotes will still work until you reprogram the opener unit.

The First Week: Practical Setup

With the immediate safety items done, the first week is about getting the house functional.

Set up utilities in your name. You should have arranged this before closing, but if not, do it immediately. Contact your electric, gas, water, internet, and trash collection providers. Your closing attorney or real estate agent can provide meter numbers and account transfer information if needed.

Deep clean before you unpack. A house is much easier to clean when it's empty than when it's full of your belongings. Pay particular attention to the oven, refrigerator, bathroom grout, and any storage areas. If the previous owners had pets, consider having carpets professionally cleaned before your furniture arrives.

Change HVAC filters. Replace all air filters on your first day in the house. You don't know when they were last changed, and fresh filters are cheap insurance against circulating dust and debris through a new HVAC system.

Run all appliances once. Dishwasher, washer, dryer, refrigerator — run each one through a cycle and watch for leaks, unusual noises, or error codes. The time to discover a leaking washing machine connection is before your belongings are surrounding it.

Check the water heater temperature. The recommended setting is 120°F. Settings above 140°F create scalding risk; below 120°F increases bacteria risk. The thermostat is on the water heater itself, usually behind an access panel.

Update your address. Even if you filed USPS mail forwarding before the move, go through a full address update list now:

• Driver's license and vehicle registration (required within 30 days in most states)
• IRS (Form 8822)
• Social Security Administration
• All bank and credit card accounts
• Health, auto, and homeowner's insurance
• Employer HR records
• Voter registration
• Doctor, dentist, pharmacy

Review and activate your homeowner's insurance. If you have a mortgage, you were required to have homeowner's insurance at closing. Read your policy now — understand what's covered and what's not. Flooding is not covered by standard homeowner's insurance; if your property has any flood risk, get a separate flood insurance quote.

The First Two Weeks: Learn Your Home

Find the property survey. Your closing documents should include a survey showing your property lines. Walk your property and understand exactly where your land ends. This matters for fencing, landscaping, additions, and any neighbor disputes.

Read your inspection report again. Your home inspection report, reviewed during escrow, identifies every deficiency in the property. Things you may have accepted during negotiation need attention now. Create a priority list: safety items first, structural items second, cosmetic items last.

Test every door and window. Do all locks engage properly? Are there any windows that don't open, close, or lock? Check for gaps in weatherstripping or caulking around windows and exterior doors — these affect both energy efficiency and pest intrusion.

Locate the sewer cleanout. The sewer cleanout is an access point for clearing clogged drains, usually a white or black PVC cap in your yard or basement. Knowing where it is saves time (and money) if you ever need a plumber for a main line blockage.

Introduce yourself to neighbors. A brief, friendly introduction serves a practical purpose: neighbors who know you will be more likely to call you if they see something unusual at your property. This matters especially if you travel.

The First Month: Insurance, Documentation, and Records

Create a home inventory for insurance purposes. Document your belongings with photographs or video, room by room. Store the files somewhere off-site (Google Drive, Dropbox) or in a safe deposit box. This documentation is essential if you ever file a homeowner's insurance claim for theft, fire, or weather damage.

Understand your homeowner's insurance deductible. Know what your deductible is before you need to use your insurance. Common deductibles range from $500 to $5,000. In areas prone to wind or hail damage, some policies have separate, higher deductibles for those specific perils — read the fine print now.

Set up a home maintenance fund. The standard recommendation is 1–2% of your home's purchase price per year for maintenance and repairs. On a $300,000 home, that's $3,000–$6,000 annually. Start a dedicated savings account now, before you need it.

Register your appliances. Find the model and serial numbers for all appliances (usually inside the door or on the back). Register them with manufacturers for warranty coverage and recall notifications.

File for homestead exemption. In many states, homestead exemption reduces your property tax assessment if the home is your primary residence. Deadlines vary by state, but many are in January or April following your first year of ownership. Check your county assessor's website and file before the deadline.

Review HOA documents if applicable. If your home is in a homeowners association, read the CC&Rs (Covenants, Conditions, and Restrictions) now. Understanding what's allowed and what isn't before you plan any renovations or exterior changes saves significant friction later.

Get quotes for deferred maintenance from the inspection report. If your inspection flagged items that weren't resolved before closing — a roof near end of life, an aging HVAC system, a crawl space with moisture issues — get contractor quotes now, while you have time to plan and budget, rather than when something fails unexpectedly.

The Moving Day Overlap

If you're moving in on or shortly after closing day, the logistics of a move and the post-closing setup tasks overlap. The practical order is:

1. Safety items first (rekey locks, locate shutoffs, test detectors)
2. Utilities confirmed active
3. Walk through with movers and direct placement of large furniture
4. Unpack essentials box (see below)
5. Everything else over the following days

The essentials box is the one box that should arrive in your car, not the moving truck. Pack it before your move: toilet paper, hand soap, a towel, phone chargers, a power strip, prescription medications, a change of clothes per person, coffee maker or kettle, snacks, basic tools, and trash bags. When you're exhausted at 8 PM on closing day, this box is all you need.

The Complete Moving-In Checklist

The full scope of moving into a home you've just purchased — combining the post-closing tasks above with the physical logistics of the move itself — is more than most people can hold in their heads while it's happening. Having everything written down, with a clear timeline, is the only reliable system.

Our Moving Checklist covers the complete 8-week move-in process, from the moment you have a confirmed closing date through your first month in the house. It includes a post-closing task checklist, room-by-room unpacking guides, a new homeowner safety checklist, and an address change master list covering 40+ accounts.

The first month of homeownership sets the tone for everything that follows. Starting organized — knowing where the shutoffs are, having your insurance in order, understanding what your inspection flagged — makes the difference between a home that feels like a relief and one that feels like a project.
