Your First 90 Days as a Homeowner

By Clare Bellwood · 2026-04-23 · 9 min read

Welcome. Buying a home is a big deal. Nobody really prepares you for the week after closing, which sits somewhere between elation and quiet existential dread about all the systems you now own and are responsible for. If you are reading this in that week, you are in the right place. If you are reading it in the weeks before closing, even better.

This guide covers what is worth doing in your first three months. It is written for people in their first home, with no prior experience of the maintenance side of ownership, who want to avoid expensive mistakes without drowning in a list of everything they could theoretically do.

The order matters. Some items are one-time tasks. Others are habits you are starting to build. Collectively, they reduce the number of unpleasant surprises in your first year, and they help you sleep better in the ones after.

Week one: stabilize and orient

The first week is not about being productive. It is about getting the basics in place so nothing bad happens while you are unpacking.

Locate and label your shutoffs. The main water shutoff. The individual water shutoffs for each bathroom and the kitchen. The main gas shutoff if you have one. The breaker panel. Label each one. Take photographs. Save the photographs in a shared note on your phone that anyone in your household can find. This sounds obvious. Most homeowners have never done it. It matters the first time you have a pipe leak at two in the morning and need to stop the water before anything else.

Find your HVAC filter and water heater. Check the date on the HVAC filter. Most need replacement every 60 to 90 days. If the one currently installed has been there longer, replace it today. Check the age of the water heater by reading the data plate on the side of the tank. Write that number down. You will come back to it.

Get a fire extinguisher for the kitchen and one for the garage. This is not paranoia. The kitchen is where almost all home fires start, and the difference between a small grease fire handled in thirty seconds and a $50,000 insurance claim is the presence of an extinguisher within reach.

Get carbon monoxide detectors if the previous owner did not. Especially if you have gas appliances. CO is genuinely dangerous and genuinely undetectable without a sensor. Most hardware stores stock combination smoke-and-CO units for around $40 each, and battery-powered models install in five minutes.

Weeks two and three: read your paperwork

This is the week you sit down with the documents you received at closing and actually read them. Most new homeowners file them and never look at them again. That is the mistake.

Read your home inspection report cover to cover. Not just the summary page. Read the details on each system, each appliance, each observation. The inspector's notes on the HVAC's age, the roof's condition, the foundation's status, are gold. The inspector is telling you which things are likely to need attention and when. Take notes. Build a list of items flagged as "monitor," "end of expected life," or "recommend replacement in the next X years." That list will guide your decisions for the next five years.

Read your homeowners insurance policy. Specifically the declarations page and the exclusions. Most policies exclude flood damage entirely. Most cap personal property coverage at 50% or 70% of the dwelling coverage. Most have specific sub-limits on things like jewelry, firearms, and electronics. Know what is covered and what is not. If the exclusions worry you, now is the time to buy a rider or change policies. It is much harder to do after a claim.

Read your mortgage paperwork for the escrow provisions. Most mortgages escrow your homeowners insurance and property taxes. Know how much is in your escrow account, when the next disbursements are scheduled, and whether your lender sends you an annual escrow statement. Escrow shortages are a common first-year surprise, and they are always easier to absorb when you saw them coming.

If you bought a condo or a home in an HOA, read the bylaws. Plural. Read them. The things you can and cannot do to your property, the fees that can be assessed, the rules about rentals and pets, are all buried in the bylaws. First-time HOA homeowners are surprised by these rules approximately one hundred percent of the time.

Weeks three and four: set up protection

By now you are oriented and have read the paperwork. Now you build the protection stack. Most first-time homeowners arrive at closing with homeowners insurance and nothing else. That is the minimum. It is not complete.

Homeowners insurance is already in place. Your mortgage required it. Review the coverage limits against the actual replacement cost of your home and your contents. Most policies are slightly under-insured on contents because people underestimate what they own until they try to replace it.

Consider a home warranty, which is not the same thing as homeowners insurance. Home warranty covers the mechanical systems in your house (HVAC, water heater, plumbing, electrical) and major appliances (dishwasher, refrigerator, washer, dryer) when they break from normal use. Homeowners insurance covers the structure and your belongings when something catastrophic happens (fire, wind, theft, certain types of water damage). The two products overlap on almost nothing. Most homeowners who buy both find the warranty pays for itself within the first two years, especially in homes with systems over ten years old.

A warranty is worth a serious look if your inspection flagged any major systems as "near end of life" or "monitor closely." If your inspection came back clean on everything and all major systems are under ten years old, you can probably skip warranty for now and revisit in five years. The decision is not urgent, and it is okay to take a month to think about it.

Build an emergency fund earmarked for the house. Start with $3,000 and work toward $6,000 in the first year. This is separate from your general emergency fund. It is the money you will use for the things homeowners insurance and home warranty do not cover, which turns out to be a lot of smaller items. Roof repair from a specific branch fall. A plumber call at midnight for a non-covered clog. A fence section that needs replacement. The list is long and mundane.

Weeks five through eight: learn your systems

By now you have stabilized, read the paperwork, and set up the financial protection. The next phase is learning the actual mechanical systems in your house. This sounds boring. It is. It also saves you money and prevents the kind of breakdown that wakes you up.

HVAC: learn the service schedule. Most central HVAC systems need a professional tune-up twice a year, once before summer and once before winter. The tune-up costs around $100 to $150 per visit. It extends the life of the system by years and catches problems before they become emergencies. Schedule both now. Put them on your calendar as recurring.

Water heater: learn the flush schedule. Tank water heaters need to be flushed once a year to remove sediment. Sediment buildup is the single most common cause of premature water heater failure. The flush takes thirty minutes and is a reasonable DIY project. There are good tutorials online. Or have a plumber do it for around $100 at an annual visit.

Roof: take photos every spring and fall. Stand in your yard and take photos of each side of your roof. Save them dated. Every six months, take new photos and compare. You are looking for missing shingles, damage around flashing, any visible sag in the roof line. Most roof problems are visible from the ground if you know what you are looking for.

Gutters: clean twice a year, more if you have heavy tree cover. Clogged gutters are responsible for a surprising percentage of water damage claims, because water that cannot drain properly ends up going where you do not want it. A gutter cleaning service costs $100 to $200 per visit. If you are comfortable on a ladder, it is a free DIY project.

Electrical panel: identify what each breaker controls and label them. Most panels are not labeled, or the labels are wrong. On a quiet weekend, flip one breaker at a time and identify what turns off. Label with masking tape and a permanent marker. You will thank yourself when the washer is misbehaving and you need to isolate it from everything else.

Weeks nine through twelve: build the habits

The last month is about making the first three months stick. None of the above matters if the habits evaporate after a single weekend of good intentions.

Set up a maintenance calendar. A simple shared Google calendar works. Recurring entries for HVAC tune-ups, water heater flush, gutter cleaning, roof photo checks, HVAC filter replacements. The calendar runs itself once set up.

Build a contractor list. You need the phone numbers of a reliable plumber, a reliable HVAC tech, a reliable electrician, and a reliable handyperson for general repairs. Ask neighbors for recommendations. Interview at least two in each category during a non-emergency. You do not want to be looking for an electrician at ten on a Friday night.

Document everything in one place. Home inspection report, insurance policy, warranty contract, HVAC service records, roof photos, receipts for any home improvements. Keep it all in a single folder or a single cloud drive. When you sell the house in ten years, this folder will add thousands to your sale price. In the meantime, it will save you many hours of "where did we put that."

The big picture

The first three months of home ownership are disorienting. You are learning a new neighborhood, a new commute, a new mortgage payment, and a new set of mechanical systems that you are now responsible for. It is normal to feel behind.

The checklist above is designed to move you through the disorientation with a clear sense of what is covered, what is at risk, and what needs your attention first. Some items take an hour. Others take a Saturday. Collectively, they take you from "new homeowner hoping nothing breaks" to "homeowner who has a plan when something breaks."

And something will break. Eventually. The difference between a stressful homeowner and a calm one is not that things go wrong less often. It is that the calm one has already decided what to do when they do.

You are building that preparation now. Welcome.
