New Homeowner Checklist: What to Do After Buying a House

A new homeowner checklist helps you turn the first days after closing into an organized transition instead of a scramble. Once the keys are yours, the priorities change quickly: you need to secure the property, understand the home’s systems, organize mortgage and insurance records, plan repairs, build a maintenance routine, and make sure the costs of ownership fit your ongoing budget.

This guide is designed for U.S. homeowners who have just closed or are about to take possession. Some tasks apply almost everywhere, while others depend on your state, municipality, mortgage, insurance policy, property type, homeowners association, climate, and the systems in the home. Use the checklist as a practical operating plan, then confirm local or property-specific requirements when needed.

If you are still working through the purchase itself, start with our guide on how to buy a house. If you are still in the accepted-offer stage, our guide to what happens after an offer is accepted on a house covers the contract-to-closing process.

New Homeowner Checklist at a Glance

What to Do in the First 24 Hours

The first day is mostly about access, safety, and learning how the property works.

Change or rekey exterior locks and access codes

Unless you have reliable documentation showing who has every existing key, changing or rekeying exterior locks is a practical security step. Update garage-door remotes, keypad codes, smart-lock credentials, gate codes, and alarm-system access where applicable.

If the property includes common-access systems, a condominium association, or managed entry, confirm which parts you may change yourself and which are controlled by the association or property manager.

Locate the main water shutoff and electrical panel

Find the main water shutoff before you need it. A burst supply line or leaking fixture can cause extensive damage if you do not know how to stop the water quickly.

Also locate:

• the main electrical panel;
• clearly labeled circuit breakers or fuses;
• the gas shutoff, if the home uses natural gas or propane;
• the water heater;
• heating and cooling equipment;
• sump pump or ejector pump, if present; and
• any emergency disconnects that apply to the home.

Do not operate unfamiliar gas, electrical, generator, solar, battery-storage, or other specialized systems until you understand the manufacturer’s instructions or have qualified help.

Test smoke and carbon monoxide alarms

Do not assume alarms are working simply because they are installed.

The U.S. Fire Administration recommends smoke alarms inside and outside sleeping areas and on every level of the home, and recommends testing smoke alarms monthly. Review the USFA’s smoke alarm guidance.

The Consumer Product Safety Commission recommends carbon monoxide alarms on every level of the home and outside sleeping areas. Follow the alarm manufacturer’s instructions for placement, testing, batteries, and replacement. See the CPSC’s carbon monoxide alarm guidance.

If alarms are missing, damaged, expired, or unreliable, correct that promptly.

Confirm utilities and essential services

Make sure the services you expect are active and correctly associated with your account. Depending on the property, this may include:

• electricity;
• natural gas or propane;
• water and sewer;
• trash and recycling;
• internet;
• security monitoring; and
• private well, septic, or other specialized services.

Take meter readings or photographs where useful, particularly if there is any uncertainty about the transfer date or account responsibility.

Document the property’s condition

Take dated photographs or video of the home shortly after possession, especially major rooms, appliances included in the sale, visible systems, and any existing damage or deferred repairs.

This record can help you track maintenance, insurance claims, improvements, and changes over time. It can also make it easier to build a more complete home inventory later.

What to Do in Your First Week

The first week is when you move from immediate safety to understanding the financial, administrative, and physical responsibilities of owning the property.

Organize your closing and ownership documents

The Consumer Financial Protection Bureau recommends keeping your final loan and purchase documents in a safe place. Its post-closing guidance specifically highlights the Closing Disclosure, promissory note, mortgage or deed of trust, and deed. Review the CFPB’s after-closing guidance.

Create one secure physical or digital home file for documents such as:

• purchase agreement and amendments;
• Closing Disclosure;
• promissory note;
• mortgage or deed of trust;
• deed or recorded ownership documents when available;
• title insurance policies;
• homeowners insurance;
• inspection reports;
• appraisal;
• warranties;
• surveys or plats;
• association documents; and
• receipts for future repairs and improvements.

Keep sensitive financial and identity information in a secure location rather than an ordinary shared folder.

Confirm who services your mortgage and how to make payments

The company that made your mortgage is not always the company that will service it. The CFPB explains that the mortgage servicer is the company that sends statements and handles day-to-day loan administration and payments. If you want a refresher on the financing process that led to this point, see our guide on how to get a mortgage. See the CFPB’s explanation of the difference between a mortgage lender and mortgage servicer.

Verify:

• the current servicer;
• your loan number;
• the first payment due date shown in your loan documents or servicer information;
• the approved payment method;
• the servicer’s official website and phone number; and
• whether automatic payments require separate enrollment.

Do not assume the first payment is due on a universal schedule. Use your signed loan documents and official servicer communications.

Mortgage servicing can also be transferred. If that happens, follow the transfer notices and payment instructions carefully. The CFPB explains what happens when mortgage servicing changes.

Understand your escrow account, if you have one

An escrow account may collect part of each mortgage payment to pay certain property expenses such as property taxes and homeowners insurance. Your servicer typically manages the account and pays covered bills when due.

The CFPB notes that taxes and insurance costs can change, which can also change the escrow portion of your monthly payment. See its explanation of escrow or impound accounts.

Check your loan documents and statements to understand:

• which expenses are included in escrow;
• which expenses you must pay separately;
• when annual escrow analyses occur; and
• what to do if a tax or insurance bill appears unpaid.

Homeowners association dues are often separate from mortgage escrow, so confirm how and when those are paid if they apply.

Review your homeowners insurance policy

Do not stop thinking about insurance simply because the lender accepted the policy at closing.

Review:

• dwelling coverage;
• personal-property coverage;
• liability limits;
• deductibles;
• exclusions;
• endorsements;
• loss-of-use coverage; and
• any separate flood, earthquake, wind, or other policies.

The CFPB notes that standard homeowners insurance does not generally cover flood or earthquake damage. Review its homeowners insurance guidance.

Make sure the insurer has the correct mailing address, mortgagee information, and contact details.

Revisit the home inspection report

Now that you own the home, the inspection report can become a maintenance-planning document.

Sort findings into practical categories:

1. Immediate safety or active-damage issues
2. Repairs that could worsen if delayed
3. Systems that need service or specialist evaluation
4. Routine maintenance
5. Cosmetic or optional improvements

Do not let visible decorating projects consume the money you may need for roof, drainage, HVAC, plumbing, electrical, foundation, appliance, or moisture-related issues identified during due diligence.

Start a home inventory

A home inventory is a record of your belongings and can be useful when documenting an insurance claim.

You do not need a complicated system. Start with room-by-room photographs or video, then record higher-value items with model numbers, serial numbers, receipts, or purchase dates where practical.

Store a copy somewhere you can access even if the home itself is damaged.

What to Do in Your First Month

By the end of the first month, your goal should be to move from reacting to the house to operating it deliberately.

Build a realistic homeowner budget

Your housing cost is not just the mortgage payment.

Depending on the property, you may need to budget for:

• mortgage principal and interest;
• property taxes;
• homeowners insurance;
• mortgage insurance;
• HOA or condominium dues;
• electricity, gas, water, sewer, and trash;
• internet and security;
• landscaping or snow removal;
• pest control;
• routine maintenance;
• repairs; and
• major future replacements.

The CFPB recommends accounting for maintenance, repairs, utilities, taxes, insurance, and emergency savings when evaluating homeownership costs. See its guidance on budgeting for the full cost of a home.

Avoid relying on a universal percentage of the home’s value as the “correct” maintenance budget. A new condominium and an older detached home with a large roof, yard, septic system, and multiple mechanical systems can have very different cost profiles.

Build reserves based on your actual property, inspection findings, system ages, insurance deductibles, and financial capacity.

Create a maintenance calendar

A calendar turns home maintenance into scheduled work rather than something you remember only after a failure.

For a recurring monthly, seasonal, and annual framework, use our home maintenance checklist to organize the work by cadence and home system.

Start by listing the home’s major components:

• heating and cooling;
• water heater;
• roof and gutters;
• plumbing;
• electrical system;
• sump pump;
• septic or well equipment;
• appliances;
• fireplace or chimney;
• exterior drainage;
• doors and windows;
• landscaping and irrigation;
• smoke and CO alarms; and
• any property-specific systems.

Use manufacturer instructions, inspection recommendations, qualified contractor guidance, and local climate conditions to set appropriate intervals.

Collect manuals, warranties, and service history

Create a single record for each important appliance or system.

Include:

• manufacturer;
• model and serial number;
• installation date when known;
• warranty information;
• installer or contractor;
• filter or consumable specifications;
• previous service records; and
• future maintenance reminders.

If the seller left manuals or receipts, scan them before they disappear into a drawer.

Learn where water goes around the property

Water problems can become expensive quickly.

During rain, snowmelt, irrigation, or routine use, pay attention to:

• gutters and downspouts;
• grading;
• basement or crawlspace moisture;
• sump-pump operation;
• exterior drains;
• roof runoff;
• plumbing leaks; and
• areas where water collects near the foundation.

If you see active leakage, significant moisture, structural movement, or drainage problems you do not understand, get appropriate professional advice rather than waiting for visible damage to spread.

Review radon and other location-specific risks

Any home can have a radon problem. The EPA recommends testing homes for radon and provides guidance for buyers and homeowners. See the EPA’s radon and real estate resources.

Depending on your location and property, other risks may include:

• flood;
• wildfire;
• wind or hail;
• earthquake;
• termites or other pests;
• private well contamination;
• septic failure; or
• extreme heat or cold.

Your goal is not to become an expert in every hazard. It is to know which risks matter for your property and what inspections, maintenance, insurance, or emergency planning they require.

What to Do in Your First 90 Days

The first 90 days are a good time to address deferred work and establish systems you can maintain for years.

Complete priority repairs from your inspection and walkthrough

Work through the repair list in order of consequence rather than appearance.

A useful priority order is:

1. active safety hazards;
2. water intrusion or active leaks;
3. structural or electrical concerns;
4. heating, cooling, plumbing, or essential-system failures;
5. defects likely to cause larger damage;
6. preventive maintenance;
7. energy or comfort improvements;
8. cosmetic upgrades.

Obtain permits and qualified professional help where required. Do not assume every repair is appropriate for DIY simply because a tutorial exists.

Establish seasonal maintenance routines

Home-care priorities change with climate and season.

Your routine may include preparing heating or cooling equipment, cleaning gutters, checking drainage, protecting exterior plumbing from freezing, maintaining landscaping, servicing fireplaces, inspecting exterior seals, or preparing for severe weather.

Use local climate, manufacturer instructions, and qualified advice rather than a generic nationwide calendar for tasks that depend on geography.

Build a trusted service-provider list

A good time to find help is before an emergency.

Create a list of qualified local providers you may need, such as:

• plumber;
• electrician;
• HVAC contractor;
• roofer;
• locksmith;
• appliance service provider;
• pest-control provider;
• tree service;
• water or septic specialist; and
• insurance agent or claims contact.

Keep emergency numbers and after-hours procedures with your home records.

Review property-tax and homeowner programs carefully

Property taxes and homeowner exemptions vary significantly by state and locality.

Some jurisdictions offer homestead exemptions, assessment programs, senior or disability relief, veteran benefits, or other homeowner programs. Eligibility, filing dates, and application procedures are local.

Do not rely on a national checklist for a specific deadline. Check your county, city, assessor, or state tax authority for rules that apply to your property.

Organize records that may affect your tax basis

The IRS explains that homeowners should keep records relating to the basis and adjusted basis of the home, including settlement papers and records of improvements that may affect basis. Review IRS Publication 530, Tax Information for Homeowners.

Keep clear records of qualifying improvements, additions, and other basis-related items. Not every repair or home expense changes basis, and not every housing cost is deductible, so use current IRS guidance or a qualified tax professional for your specific situation.

What to Do During Your First Year

The first year is when isolated tasks should become a repeatable homeownership system.

Review your insurance at renewal

Do not automatically renew without reviewing what changed.

Check:

• reconstruction or dwelling limits;
• deductibles;
• endorsements;
• major improvements you made;
• new valuable property;
• liability needs;
• changes in local hazard exposure; and
• separate flood, wind, earthquake, or other coverage where relevant.

Insurance needs can change as your property and finances change.

Review escrow statements and mortgage-payment changes

If your loan includes escrow, your servicer generally performs periodic escrow analysis. Property taxes or insurance premiums may change, causing the escrow portion of your total payment to rise or fall.

The CFPB recommends monitoring mortgage statements and tax and insurance bills so you can identify escrow issues. See its guidance on escrow account problems and monitoring.

If your payment changes, review the statement before assuming the mortgage interest rate changed.

Update your home inventory and property records

Add:

• major purchases;
• renovations;
• system replacements;
• new serial numbers;
• contractor invoices;
• warranties;
• permits; and
• before-and-after photographs.

A well-maintained ownership record can help with insurance, maintenance planning, taxes, future refinancing, and an eventual sale.

When you are ready to sell, our how to sell a house guide walks through preparation, pricing, listing, offers, negotiations, closing, and the final handoff.

Reassess your repair reserve

After a year, you know much more about the home than you did at closing.

Review:

• what you actually spent on maintenance and repairs;
• which systems are nearing the end of expected service life;
• insurance deductibles;
• future major projects; and
• how much emergency cash you want available.

Adjust your savings plan based on the home you actually own rather than a generic rule of thumb.

Create a repeatable annual home review

Once a year, review the home as a system.

Ask:

• Are the safety alarms current and working?
• Are there active leaks or moisture issues?
• What maintenance is due?
• Which systems are aging?
• Have insurance needs changed?
• Has the mortgage or escrow payment changed?
• Are property-tax records current?
• Are improvement receipts and warranties organized?
• Is the emergency contact list still accurate?
• Does the repair reserve still fit the property’s likely needs?

A short annual review can prevent small administrative or maintenance issues from being ignored for years.

New Homeowner Records to Keep

A well-organized homeowner file should make it easy to answer questions about ownership, financing, insurance, repairs, and improvements.

Consider keeping:

Back up important electronic files securely and keep critical records accessible even if the home is damaged.

Common New Homeowner Mistakes to Avoid

Spending the entire reserve on cosmetic upgrades

New paint, furniture, and decorating can wait if the roof leaks, the electrical system needs attention, or the HVAC equipment is near failure.

Preserve enough liquidity to handle problems you did not know about at closing.

Ignoring the inspection report after closing

The inspection was not useful only for negotiation. It can become the first draft of your maintenance and repair plan.

Not learning the shutoffs until there is an emergency

Knowing how to stop water, electricity, or other utilities safely can reduce damage and confusion when something fails.

Assuming mortgage servicing will never change

Your servicer can change even when your mortgage terms do not. Read transfer notices and verify where future payments should go.

Ignoring escrow, insurance, or tax notices

A mortgage on autopay does not eliminate your responsibility to review statements and bills. Taxes, insurance premiums, and escrow payments can change.

Treating every homeowner rule as nationwide

Property taxes, homestead programs, permits, disclosures, building codes, HOA obligations, and many insurance issues depend on state or local rules.

Failing to document improvements

Receipts, permits, contracts, and photographs can matter later for warranties, insurance, resale, and tax-basis records.

Waiting for maintenance to become a repair

Routine maintenance cannot prevent every failure, but neglect often turns small issues into larger ones. Build the calendar while the home is still new to you.

Frequently Asked Questions About a New Homeowner Checklist

What should a new homeowner do first?

Start with access and safety. Confirm you control the locks and codes, locate the main water shutoff and electrical panel, test smoke and carbon monoxide alarms, verify essential utilities, and document the property’s condition.

Then organize your closing, mortgage, insurance, inspection, and ownership records.

What should you do after closing on a house?

After closing, move from transaction tasks to ownership tasks. Secure the property, confirm the mortgage servicer and payment instructions, understand escrow, review insurance, revisit the inspection report, create a repair and maintenance plan, and organize important records.

When is the first mortgage payment due?

There is no single due date that applies to every new mortgage. Check your promissory note, Closing Disclosure, payment coupon or statement, and official servicer instructions.

Do not rely on a generic online timeline when your loan documents provide the actual due date.

What documents should new homeowners keep?

Keep your Closing Disclosure, promissory note, mortgage or deed of trust, deed or ownership records, title insurance, homeowners insurance, inspection reports, warranties, contractor records, tax records, and documents relating to improvements.

The CFPB recommends preserving key closing documents, while IRS Publication 530 explains the importance of records that support the home’s basis and adjusted basis.

How much money should a new homeowner keep for repairs?

There is no universal amount or percentage that is right for every property.

Your reserve should reflect your emergency fund, insurance deductibles, inspection findings, age and condition of major systems, property type, expected maintenance, and financial capacity. An older detached home may need a different reserve than a newer condominium.

Should you change the locks after buying a house?

Changing or rekeying exterior locks is a practical security step because you may not know who still has copies of old keys. Also update garage remotes, keypad codes, smart locks, alarm credentials, and other access systems where applicable.

What maintenance should you do in the first year?

Start with the manufacturer and property-specific requirements for HVAC equipment, water heater, roof and gutters, plumbing, drainage, alarms, appliances, fireplaces, sump pumps, wells, septic systems, and other major components.

Build a seasonal calendar that fits your local climate rather than using a one-size-fits-all national schedule.

What should first-time homeowners budget for?

In addition to the mortgage, plan for property taxes, insurance, utilities, HOA or condominium dues where applicable, routine maintenance, repairs, major replacements, and an emergency reserve.

The exact mix depends on your property and whether taxes and insurance are paid through mortgage escrow.

Conclusion

A new homeowner checklist is most useful when it becomes a system you can keep using after the boxes are unpacked.

In the first 24 hours, focus on security, shutoffs, alarms, utilities, and the condition of the home. During the first week, organize your closing and mortgage records, confirm the servicer, understand insurance and escrow, review the inspection report, and begin a home inventory. During the first month and first 90 days, build the budget, maintenance schedule, repair plan, emergency contacts, and property records that will make ownership easier to manage.

By the end of the first year, the goal is not to have a perfect house. It is to understand how your home works, know what it costs to operate, keep the right records, maintain the systems that protect it, and have a plan for the expenses and responsibilities that come with ownership.

This guide provides general U.S. information. Mortgage servicing, taxes, insurance, building requirements, homeowner programs, and property-maintenance needs can vary by loan, state, locality, association, climate, and home.

Your Next Step

Keep this checklist with your home records and turn each time period into reminders on your calendar. Start with the safety and administrative tasks that cannot wait, then work through repairs and maintenance according to the actual condition of your home.
