New Homeowner Checklist: Your First 90 Days After Closing

You just handed over the biggest check of your life and signed more paper than you thought humanly possible. Now what? The closing table is behind you, but the real work of owning a home starts the moment you pick up the keys.

First-time buyers now make up just 21% of all home purchasers in 2026 — the lowest share since the National Association of Realtors began tracking it in 1981. The typical first-time buyer is now 40 years old, which means many people come to homeownership with adult lives already in motion, limited margin for error, and no roadmap for what actually needs to happen in those first three months.

This new homeowner checklist gives you that roadmap. It breaks the first 90 days into concrete, time-ordered tasks so nothing important falls through the cracks — and so you don’t spend the next year discovering what you should have done on day one.

Day 1: Secure the Property and Your Paperwork

Before anything else — before you carry a single box inside — do three things.

Change or rekey the locks. The seller handed you a key, but you have no idea how many copies exist. Previous owners, pet sitters, contractors, and neighbors may all have one. Rekeying costs $20–$80 per lock and takes a locksmith about 20 minutes per door. Changing a deadbolt entirely runs $50–$200. Either option works. Do it on closing day, not next weekend.

Reset the garage door code and delete the previous owner’s remote from the opener’s memory. Check the owner’s manual or look up your model number online — it takes about two minutes.

Find the three shutoffs before anything breaks. Locate your main water shutoff valve, your gas shutoff (if applicable), and your electrical panel. Label the panel if the previous owner didn’t. You do not want to hunt for these at midnight with water pouring from a burst pipe.

Secure your closing packet. Scan or photograph your Closing Disclosure, deed, title insurance policy, mortgage note, and homeowners insurance declarations page. Store digital copies in a cloud-backed folder and put the paper originals somewhere fireproof. Everything downstream — changing your address, filing for your homestead exemption, reviewing your escrow — depends on having these documents findable later.

Test all smoke and carbon monoxide detectors. Push the test button on each one. Replace batteries if the unit is more than six months old or if it doesn’t respond. Add detectors on every floor and within 10 feet of each bedroom door if the previous owner left gaps.

Week 1: Get Services Running and Your Address Updated

Once you’re physically secure, turn your attention to the administrative layer.

Transfer utilities into your name. Call or log in to set up electricity, gas, water and sewer, internet, and trash collection. Aim to have accounts in your name starting on your closing date so there’s no gap. If you’ve only rented before, some providers will require a new account application with a credit check — allow an extra business day or two.

Forward your mail. Go to USPS.com and submit a change-of-address form (accept a future date if you’re doing this before move-in). Then update your address individually with:

• Your employer’s HR system
• Every bank and credit card
• The DMV — most states give you 30 days; do it in week one
• The IRS via Form 8822 (especially important if you’re expecting a refund or correspondence)
• Any subscription services or memberships

Document the home with photos before you move in. Walk every room with your phone and photograph walls, floors, ceilings, and fixtures before furniture covers anything. This is your baseline record. If a dispute ever arises about when damage occurred, these photos are your evidence.

Month 1: New Homeowner Must-Dos — Insurance and Warranties

Your mortgage lender required you to have homeowners insurance, but most new buyers sign whatever was cheapest and move on. Month one is when you actually read what you have.

Review your policy for three things:

1. Dwelling coverage — Is it enough to rebuild the home at current local construction costs? Not market value, replacement cost. Lumber and labor prices have risen sharply; many policies go years without adjustment.
2. Personal property limits — Standard policies cover 50–70% of your dwelling amount for belongings, but high-value items like jewelry, art, electronics, or musical instruments often have per-category sub-limits as low as $1,500. If you own anything worth more than that, ask your insurer about scheduling it separately.
3. Your deductible — Know what you’d owe out-of-pocket before coverage kicks in, especially for wind and hail if you’re in a storm-prone area.

If anything looks thin, this is the cheapest time to fix it — before you file a claim.

Create a home inventory. An inventory is simply a record of what you own, room by room, with make, model, estimated value, and a photo. If a fire or theft ever wipes out your belongings, you’ll need this list to file an accurate claim. Without it, you’re guessing — and insurers know it. Dib automates a big part of this: point your phone at an appliance or piece of equipment and it identifies the item, pulls the model number, and stores it with your other rooms in the cloud. Read more in our complete home inventory guide.

Register your appliance warranties. The day you notice your dishwasher leaking is not the day you want to search for the model number. Spend 30 minutes in month one registering every major appliance, HVAC unit, and water heater with the manufacturer. If the previous owners left manuals in a kitchen drawer, keep them. If not, search the model number and download the PDF. Our guide on how to track appliance warranties covers the full process.

File for your homestead exemption if your state offers one. Most states that have one require you to apply within the first year of purchase, with a deadline sometime in the first quarter of the following year. Florida’s, for example, reduces taxable value by up to $50,000 and saves qualifying homeowners $500–$2,000 annually. Miss the deadline and you wait another full year. Check your county’s property appraiser or assessor website as soon as you’re settled.

New Homeowner Financial Checklist: Building Your Cushion

Here’s the number that surprises most new owners: according to a May 2026 Clever Real Estate report, the typical homeowner spends $23,686 per year on non-mortgage costs — utilities, maintenance, property taxes, and insurance combined. Over a 30-year mortgage, that adds up to more than $710,000 on top of the loan itself.

The same report found that 45% of homeowners say ownership costs more than they expected, and 55% couldn’t cover a $5,000 emergency repair without going into credit card debt.

Set up a dedicated home repair fund. This is separate from your personal emergency fund. The standard advice — budget 1% of your home’s value annually for maintenance — is a floor, not a ceiling, and it doesn’t account for year one. HomeScore’s 2026 first-year panel found that new owners spend a median of $4,830 on repairs in year one, with a typical range of $2,800–$11,500. The recommended budget is 1.5% of your purchase price for the first 12 months. On a $450,000 home, that’s $6,750 set aside and accessible.

Review your first mortgage statement carefully. It arrives roughly 30 days after closing. Verify the loan amount, interest rate, payment amount, and escrow breakdown against your Closing Disclosure. Discrepancies happen — lenders miscalculate escrow, property tax estimates lag behind reality — and they’re far easier to correct in month one than in year two.

Add property tax due dates to your calendar. Know whether your lender handles these through escrow or if you pay them directly. Missed property tax payments carry penalties that compound.

For a broader look at tracking your equity and financial position, our home value tracking guide walks through the numbers.

Month 2–3: Set Up a Maintenance System That Actually Works

Deferred maintenance is the biggest financial risk in your first year. Sixty-six percent of buyers in one 2026 survey experienced unexpected home issues after closing, and the most common category was cosmetic or plumbing failures that compounded because no one caught them early.

Schedule an HVAC service call. If the home came with the previous owner’s HVAC unit, you don’t know the last time it was serviced. Sixty-two percent of homes in the HomeScore 2026 panel needed some HVAC service in year one; the median cost was $485, but catching a failing capacitor early prevents a $5,000–$12,000 replacement mid-summer. Change the air filter immediately and put a quarterly filter-change reminder in your phone.

Inspect the water heater. Check the age (stamped on the label or encoded in the serial number), look for rust around the base or fittings, and flush the tank if it hasn’t been done recently. Water heaters last 8–12 years; if yours is close to that mark, budget for a replacement and start comparing your options.

Walk the roof after the first rainstorm. You don’t have to climb up there — use binoculars. Look for missing shingles, soft spots in the fascia, or staining on the eaves inside your attic. Thirty-one percent of new-homeowner panel respondents needed roof patches in year one; the median was $525, but a small flashing failure left unaddressed can mean interior water damage that costs ten times that.

Build your maintenance calendar. See our month-by-month home maintenance schedule for the full year. The short version: HVAC filters monthly, smoke detector batteries twice a year, gutters cleaned twice a year, water heater flushed annually, exterior caulking checked each spring and fall.

Try Dib → to attach maintenance reminders directly to the appliances and systems in your home inventory, so service intervals are tied to specific units and don’t rely on a generic calendar.

The Documents You Need to Find and Organize

Many new owners end up hunting for documents at the worst possible moment — after a claim, during a refinance, or when selling years later. Build your file system in month one.

Your physical or digital file should contain:

• Deed — the legal record that you own the property
• Title insurance policy — covers defects in the title that predate your purchase
• Closing Disclosure — your official record of every number from the transaction
• Mortgage note and deed of trust/mortgage — the agreements with your lender
• Homeowners insurance declarations page — with policy number and carrier contact
• Survey — shows the legal boundaries of your property; critical if a fence or addition ever creates a dispute
• Home inspection report — keep this indefinitely; it becomes relevant during future sales and for prioritizing repair projects
• HOA governing documents — CC&Rs, bylaws, rules, and fee schedule if applicable
• Appliance manuals, warranty cards, and service records

Our guide to essential home documents covers what to keep, where to store it, and how long each document matters.

Frequently Asked Questions

What is the most important thing to do on closing day? Change or rekey your locks. You have no way of knowing who has a copy of the previous owner’s key, and this is one task that gets harder to prioritize once the boxes arrive. It takes under an hour and costs $100–$200 for a full rekeying. Do it before you bring a single item inside.

How much should I budget for home maintenance in year one? Budget 1.5% of your purchase price for the first 12 months — higher than the standard 1% rule because year one includes one-time setup costs and inspection-deferred repairs. On a $400,000 home, that’s $6,000 set aside and accessible. According to HomeScore’s 2026 panel, the median new homeowner spent $4,830 on repairs in year one, with a typical range of $2,800–$11,500.

What is a homestead exemption and how do I get it? A homestead exemption reduces the taxable value of your primary residence, lowering your property tax bill. Most states offer one; Florida’s can reduce taxable value by up to $50,000. Deadlines vary by state and county — typically in the first quarter of the year following your purchase. Search your county assessor or property appraiser’s website as soon as you’ve settled to avoid missing a year.

Do I really need a home inventory if I already have homeowners insurance? Yes. Your insurance policy covers what you can prove you owned. After a fire or major theft, most homeowners dramatically underestimate the value of what they’ve lost because they’re recalling it from memory under stress. A room-by-room inventory with photos and model numbers is the only way to file an accurate claim and recover close to what you’re owed.

When should I expect my first mortgage payment? Your first mortgage payment is due on the first of the second month after closing. If you closed in May, your first payment is due July 1. Your lender will send your first statement; verify the amount and escrow breakdown against your Closing Disclosure before setting up autopay.

What should I do if I find something the inspector missed? Document it immediately with photos, timestamps, and written notes. Check your inspection report to see if it was mentioned and classified as minor, or if it appears absent. If the issue existed before closing and wasn’t disclosed, consult a real estate attorney. Otherwise, get multiple repair quotes and prioritize based on whether it’s a safety issue, a water intrusion risk, or purely cosmetic.

The first 90 days of homeownership concentrate more decisions than the next several years combined. Most of them aren’t complicated — they’re just easy to skip when you’re tired from the move and overwhelmed by the mortgage. Work through this checklist in order and you’ll head into year two with no expensive surprises waiting for you.
