What Insurance Do I Need When Buying a House?

Buying a house comes with a long list of things nobody fully explains to you. Insurance is near the top of that list.

Your lender will tell you that you need homeowners insurance before you can close. What they won't tell you is what to actually look for, what coverage is commonly missing, or how to know if the policy you're being handed at the last minute will actually protect you when something goes wrong.

This guide covers everything a first-time homebuyer — or any homebuyer — needs to know about insurance before they sign.

The short answer: what insurance do you actually need?

When buying a house, most buyers need at minimum:

• Homeowners insurance — required by your lender, protects the structure and your belongings
• Flood insurance — required if you are in a designated flood zone, strongly recommended even if you are not
• Title insurance — protects against ownership disputes and liens from before your purchase

Depending on your location and property, you may also need:

• Earthquake insurance — not covered by standard homeowners policies
• Wind or hurricane insurance — may be a separate policy in coastal states
• Umbrella liability insurance — extends your liability coverage beyond your homeowners policy limits

Let's walk through each one.

Homeowners insurance

Homeowners insurance is the foundation. Your mortgage lender will require you to have it in place before closing — and they will require that the coverage amount meets a minimum threshold tied to the loan.

What a standard homeowners policy covers

A standard HO-3 policy — the most common type — covers:

• The structure of your home (Coverage A) — damage from fire, wind, hail, lightning, theft, vandalism, and other named perils
• Other structures (Coverage B) — detached garages, fences, sheds
• Personal property (Coverage C) — your belongings inside the home
• Loss of use (Coverage D) — living expenses if your home becomes uninhabitable after a covered loss
• Personal liability (Coverage E) — if someone is injured on your property
• Medical payments (Coverage F) — limited medical coverage for guests injured on your property

What a standard homeowners policy does NOT cover

This is where most buyers get into trouble. Standard homeowners insurance does not cover:

• Flooding — not even an inch of water from outside the home. Requires a separate policy.
• Earthquakes — requires a separate policy or endorsement
• Normal wear and tear — insurance covers sudden and accidental losses, not maintenance
• Sewer backup — typically requires a separate endorsement
• Mold — usually capped at a low sublimit, often $5,000–$10,000
• High-value jewelry, art, or collectibles — subject to per-item sublimits without a scheduled endorsement

How much homeowners insurance do you need?

Your lender will require coverage equal to at least the loan amount. But the loan amount is not the right number to insure to.

You need enough coverage to rebuild your home from the ground up — not its market value, not what you paid for it, but what it would cost to rebuild it at today's construction costs. In many markets, especially after recent inflation in construction materials and labor, that number is significantly higher than people expect.

Ask your insurance agent for a replacement cost estimate based on the home's square footage, construction type, and features. This is the number your Coverage A limit should reflect.

The coverage gaps most first-time buyers miss

After reviewing thousands of homeowners insurance policies, the gaps that show up most consistently are:

Ordinance and Law coverage — When your home is damaged and needs to be rebuilt or repaired, local building codes may require upgrades that go beyond simply restoring what was there. Without adequate Ordinance and Law coverage, those code upgrade costs come out of your pocket. Most policies default to 10% of Coverage A — on a $400,000 home, that is $40,000, which often does not come close to covering actual code upgrade costs in a major loss.

Extended replacement cost — Construction costs fluctuate. If your home is a total loss and construction costs have risen since you bought your policy, your Coverage A limit may not be enough. Extended replacement cost coverage — typically 20% to 50% above your Coverage A limit — gives you a buffer.

Water backup coverage — Sewer and drain backup is one of the most common residential claims. A standard policy does not cover it. A water backup endorsement typically costs very little and can cover $10,000 to $25,000 in damage.

Personal property replacement cost — Standard policies pay actual cash value for personal property, which means depreciation is deducted. A five-year-old television is not worth what you paid for it. Replacement cost coverage pays what it actually costs to replace the item today.

Flood insurance

Flood is the most important coverage gap in American homeowners insurance, and the most consistently misunderstood.

Standard homeowners insurance does not cover flood damage. Period.

Not a broken pipe inside the home — that is typically covered. But water that enters your home from outside — from a storm surge, an overflowing river, heavy rainfall — is not covered by your homeowners policy regardless of how much damage it causes.

When flood insurance is required

Your lender will require flood insurance if your property is in a Special Flood Hazard Area (SFHA) — specifically FEMA flood zones labeled A or V. You can check your property's flood zone at the FEMA Flood Map Service Center.

When flood insurance is recommended even if not required

If your property is not in a high-risk flood zone, your lender will not require flood insurance. But that does not mean you should not have it.

According to FEMA, more than 20% of flood insurance claims come from properties outside high-risk flood zones. Heavy rainfall, overwhelmed drainage systems, and changing weather patterns affect properties that were never considered flood-prone.

Flood insurance through the National Flood Insurance Program (NFIP) is available to most homeowners regardless of flood zone. Private flood insurance options are also available and often offer broader coverage.

What flood insurance covers

NFIP flood insurance covers:

• The physical structure of your home up to $250,000
• Personal property up to $100,000

It does not cover additional living expenses if you are displaced. For that you would need a private flood policy with loss of use coverage.

Title insurance

Title insurance protects you against problems with the ownership history of the property — liens, unpaid taxes, ownership disputes, or errors in public records that existed before you bought the home.

There are two types:

• Lender's title insurance — required by your lender, protects the lender's interest in the property
• Owner's title insurance — optional but strongly recommended, protects your ownership interest

Owner's title insurance is a one-time premium paid at closing. It covers you for as long as you own the property. For the relatively small cost, it provides significant protection against title defects that could otherwise put your ownership of the home at risk.

Earthquake insurance

Standard homeowners insurance does not cover earthquake damage. If you are buying in an earthquake-prone area — California, the Pacific Northwest, parts of the Southeast — earthquake insurance is worth serious consideration.

Earthquake insurance is available as a standalone policy or as an endorsement to your homeowners policy. It typically covers:

• Structural damage to your home
• Personal property damage
• Additional living expenses while your home is being repaired

Earthquake policies typically carry high deductibles — often 10% to 20% of the insured value — so they are designed for significant losses, not minor damage.

Wind and hurricane insurance

In coastal states — Florida, Texas, Louisiana, the Carolinas, and others — wind damage coverage may be excluded from your standard homeowners policy or carry a separate, higher deductible.

Check your policy declarations page carefully for:

• Wind exclusions — some coastal policies exclude wind entirely
• Hurricane deductibles — often 1% to 5% of the insured value, triggered when a named storm is declared

If wind is excluded from your homeowners policy, you will need a separate wind policy — often through your state's insurer of last resort — to cover hurricane and wind damage.

Umbrella liability insurance

Your homeowners policy includes personal liability coverage — typically $100,000 to $300,000. An umbrella policy extends that coverage to $1 million or more at a relatively low annual cost.

If someone is seriously injured on your property and sues, a judgment above your homeowners liability limit comes directly from your assets. An umbrella policy is particularly worth considering if you have a swimming pool, trampoline, or other attractive nuisance on the property, or if you have significant assets to protect.

How to shop for homeowners insurance as a first-time buyer

Start early

Do not wait until a week before closing to shop for insurance. Some properties are difficult to insure — older homes, homes with certain roof conditions, homes with prior claims history — and finding coverage can take time.

Start shopping at least 30 days before your target closing date.

Get quotes from multiple carriers

Rates vary significantly between carriers for the same property and coverage. Get at least three quotes. Do not choose based on price alone — compare coverage terms, deductibles, and exclusions.

Ask specifically about these items

When talking to an insurance agent, ask:

• What is the replacement cost estimate for this home?
• What are my Ordinance and Law coverage limits?
• Is water backup covered and what is the limit?
• Does this policy pay replacement cost or actual cash value for personal property?
• Are there any wind or water exclusions?
• What is the claims process if I have a loss?

Read the declarations page before you bind coverage

The declarations page is the summary of your policy — coverage amounts, deductibles, and any endorsements. Read it before you finalize coverage. If something looks unfamiliar or a limit seems low, ask about it before closing.

After you close: review your coverage before you need it

The worst time to discover a coverage gap is after a loss. Most homeowners never look at their policy again after closing — until something goes wrong.

Before your first renewal, review your policy for the gaps listed above. If you have made improvements to the home, update your coverage amounts. If you have purchased high-value items, schedule them separately.

A policy scan can surface gaps you may not know to look for — comparing what your policy actually covers against what a real loss would cost, in plain language, before you ever need to file a claim.

The bottom line

Buying a house requires at minimum homeowners insurance and — depending on your location — flood, earthquake, or wind coverage. Title insurance protects your ownership. An umbrella policy protects your assets.

The most important thing you can do as a new homeowner is understand what your policy actually covers before you need it. Coverage gaps are not discovered when you buy insurance. They are discovered when you file a claim.
