Homeowners insurance basics: coverage types, deductibles, and how claims actually work

Every mortgage lender requires homeowners insurance, and most buyers pick a policy in 15 minutes during closing without reading it. That policy then sits untouched for 30 years while premiums climb and coverage gaps quietly grow. This guide walks the actual coverage, where standard policies fail, and how to shop it without getting burned.

The basics

Homeowners insurance covers three things: the structure, your personal property, and liability if someone is injured on your property. National average premium runs $1,500–$2,500/yr. In coastal Florida it’s $6,000+, Texas often $4,000+, California wildfire zones similar.

The most common policy form is the HO-3: open peril for the structure (everything is covered unless explicitly excluded), named peril for your contents (only listed perils trigger payout). Almost every owner-occupied single-family home runs on an HO-3.

Worth knowing: the HO-5 is a step up — open-peril for both structure AND contents, plus typically replacement cost on contents by default. Premium is usually only 10-15% higher than HO-3 and most high-value carriers (Chubb, AIG, PURE, Cincinnati) write HO-5 as their standard. If you can get one, take it. Condos run on HO-6 (“walls-in” coverage) and renters on HO-4.

The six coverages on every policy

Coverage A: Dwelling

Pays to rebuild the structure if destroyed. This is the most misunderstood number in insurance.

It is not market value. Market value includes land, location, school district. Insurance only rebuilds the building.

It should equal local rebuild cost per square foot × your square footage, plus demolition. In most markets that’s $150–$400/sf depending on construction grade and region.

A $1.5M home in CA might have a $700k rebuild cost. A $250k home in rural OH might have a $300k rebuild cost (because lumber and labor don’t care about your local school ratings). Insure to rebuild cost, not market value.

Coverage B: Other Structures

Detached garage, fence, shed, pool cage. Defaults to 10% of Coverage A. Increase if you have a meaningful detached structure.

Coverage C: Personal Property

Your stuff: furniture, electronics, clothes, kitchen, kids’ gear. Defaults to 50–70% of Coverage A.

Most policies pay actual cash value (ACV) on contents by default — replacement cost minus depreciation. A 5-year-old TV pays out at maybe $200. Always upgrade contents to replacement cost. Costs $30–$80/yr. Pays for itself the first claim.

High-value items (jewelry >$2k, art, watches, firearms) need a scheduled rider — standard policies cap each category ($1,500 jewelry total is common).

Coverage D: Loss of Use

Hotel, food, rental while your home is unlivable during repair. Defaults to 20% of Coverage A. If your home is destroyed by fire and rebuild takes 14 months, this is what keeps you housed.

Coverage E: Personal Liability

Pays if someone is injured on your property and sues. Standard limits: $100k–$300k. Bump to $500k if you have any net worth, then layer an umbrella policy ($1M for ~$200–$400/yr) once your assets exceed $500k.

Coverage F: Medical Payments

Small no-fault payouts to injured guests so they don’t sue ($1k–$5k). Cheap, useful.

Replacement cost vs ACV

This is the single most important coverage choice on the policy.

• Replacement cost (RC): pays to replace damaged property with new equivalent. A 10-year-old roof pays at full new-roof cost.
• Actual cash value (ACV): replacement cost minus depreciation. A 10-year-old roof pays at ~30% of new cost. You eat the rest.

Always pick replacement cost on dwelling AND contents. The premium difference is small. The check after a major claim is massive.

Two upgrades worth knowing about on the dwelling side:

• Extended replacement cost: pays an extra 25-50% above Coverage A if rebuild costs run over (common after a regional disaster spikes labor and materials). Cheap and standard at most carriers — ask for it.
• Guaranteed replacement cost: pays whatever it actually costs to rebuild, no cap. Increasingly hard to find in CA/FL/TX, mostly available on HNW carriers.

In FL, TX, LA, and increasingly elsewhere, insurers are forcing roof ACV (or roof “schedules” that depreciate by age) on roofs older than 10-15 years. Some carriers won’t even renew if the roof is over 20 years old — the “1-year roof rule” is real: either replace or lose coverage. Check the declarations page for an “ACV roof endorsement” or “roof surfacing schedule.” If your roof is on ACV and a hail storm totals it, you’re out tens of thousands out of pocket.

Coverage gaps you must add

A standard HO-3 doesn’t cover these. You need separate policies or riders.

• Flood: not covered, period. Get a separate NFIP or private flood policy. Required by your lender if the property is in a FEMA Special Flood Hazard Area (SFHA). Strongly recommended in any low-lying or coastal area — 20%+ of flood claims come from outside designated flood zones.
• Earthquake: separate policy in CA, NV, UT, OR, WA, parts of the Midwest near the New Madrid fault.
• Wind/hail in coastal areas: standard policy may exclude windstorm entirely in coastal counties (FL, NC, SC, TX, MS, LA, AL). You buy it from a state wind pool (TX TWIA, NC Coastal, Citizens in FL) or a separate wind carrier. Even when included, expect a separate named-storm or hurricane deductible (below).
• Sewer / drain backup: cheap rider ($30–$80/yr). Saves $20k+ on a basement flood from a backed-up sewer. Standard HO-3 excludes water that backs up through a drain or sump — if you have a basement, get this rider.
• Service line coverage: rider for buried utility lines (sewer line to street, water line). $30–$60/yr.
• Mold: most policies cap mold coverage at $5,000-10,000 even when the underlying water loss is covered. A larger mold rider is worth it on humid-climate or basement homes.
• Loss assessment (condos): pays your share of a master-policy shortfall after a building-level loss. Standard limit on an HO-6 is $1,000-$2,000; bump to $25k-$50k if your association is underinsured (which most are).
• Sinkhole: separate in FL, TN, AL.
• Slow leaks / maintenance: never covered, full stop. Sudden pipe burst is covered. Slow drip behind the wall for 6 months rotting subfloor is your problem.

Deductibles

Two flavors:

• Flat dollar: $500, $1,000, $2,500, $5,000. Applies to most claims.
• Percentage: a percent of Coverage A, usually for hurricane / named storm in coastal states or wind/hail in hail-prone states. 1%, 2%, or 5% of dwelling coverage.

A 2% hurricane deductible on a $400k dwelling is $8,000 out of pocket before insurance pays a dime. Many FL/TX owners are surprised to learn their hurricane deductible is >$10k.

Higher deductible = lower premium. Picking $2,500 instead of $500 typically saves 10–25% on premium. Worth it if you can self-fund the deductible from savings.

What drives your premium

• Location (the dominant factor): zip code, distance to coast, brush/wildfire zone, fire hydrant proximity, fire station distance
• Claims history: yours and the property’s (CLUE report)
• Roof age and material: a new roof can save 10–30%
• Construction: masonry < frame on premium
• Credit-based insurance score (used in most states — prohibited in CA, MD, MA, HI)
• Pet: certain breeds excluded entirely by some carriers
• Pool, trampoline: liability surcharge or excluded

The claim that gets you dropped

This is the rule almost no one is told: filing 2+ claims in 5 years, especially water damage, gets you non-renewed. Some carriers will non-renew on a single water claim in today’s market.

Insurance is for catastrophes, not maintenance. Filing a $3k claim for a kitchen leak isn’t worth it — you’ll save $3k now and pay $1,500/yr more in premiums for the next 5 years (plus a likely non-renewal that puts you on the residual market).

Even calling to “ask about” a claim can get logged as an inquiry on CLUE without a payout. Ask hypothetically and don’t give the address.

Rule of thumb: don’t file a claim under 2× your deductible unless it’s a liability situation. Pay small stuff out of pocket.

The CLUE report

CLUE (Comprehensive Loss Underwriting Exchange), run by LexisNexis, is the insurance industry’s claims database. It holds 5-7 years of claims history (varies by state) and claims follow the property, not just the owner.

When you’re under contract on a home, request the CLUE report from the seller (only the current owner can pull it; you have a federal right to your own under FCRA). If the property had 3 water claims in the last 5 years, you may not be able to insure it on the standard market — or the premium will be brutal.

The carrier crisis (2024-2026)

The market is the worst it’s been in a generation. Knowing the landscape changes how you shop:

• California: State Farm and Allstate stopped writing new policies in wildfire-exposed zip codes. FAIR Plan (CA’s insurer of last resort) plus a “wrap” DIC policy is now common even for non-coastal homes.
• Florida: most national admitted carriers have pulled out; Citizens (state-run) is the largest insurer. New Floridians routinely pay $6k-$15k/yr.
• Louisiana, Texas coastal, Colorado wildfire zones: same dynamic — carrier flight, state pools picking up slack.
• Surplus lines / E&S carriers (Lloyd’s of London, Lexington, Scottsdale) write what admitted carriers won’t. No state guaranty fund backstop, so vet the carrier’s AM Best rating (A- or better).

Practical implication: get the insurance quote BEFORE you go hard on the contract. In CA/FL/LA/coastal-TX, “I can insure this house at all, at this price” is now a real contingency — not a formality. An older roof, prior water claim on CLUE, or a wood shake roof in a wildfire zone can make the property uninsurable.

Concrete example

$500,000 home in suburban TX, 2,500 sf, 6 years old.

• Coverage A (dwelling): $375,000 (rebuild cost at $150/sf)
• Coverage C (contents): $260,000 at replacement cost
• Coverage E (liability): $300,000
• Flat deductible: $2,500
• Wind/hail deductible: 2% = $7,500
• Annual premium: ~$4,200/yr = $350/mo escrow

Run your full PITI in the Mortgage Calculator and double-check the insurance line is realistic for your zip code — the default estimates can be way low in high-premium states.

Shopping the policy

• Get 3+ quotes at every renewal — or every 2–3 years minimum. Carriers re-rate aggressively; loyalty costs you money.
• Bundle with auto for 10–25% discount.
• Independent agents quote multiple carriers. Captive agents (State Farm, Allstate, Farmers) only sell their own. Use both.
• Raise the deductible if you have savings to cover it.
• Ask about discounts: monitored alarm, roof age, claims-free, paid-in-full, paperless.

Common mistakes

• Insuring to market value instead of rebuild cost — you overpay premium for years.
• Skipping flood insurance in any low-lying or coastal area because “I’m not in a flood zone.” 20%+ of flood claims are outside designated zones.
• Defaulting to ACV on contents or roof. Replacement cost is almost always worth the small premium bump.
• No umbrella policy once net worth exceeds $500k. $200– $400/yr for $1M of additional liability.
• Filing small claims. Pay them yourself. Save claims for catastrophes.
• Dropping coverage after the mortgage is paid off. The lender required insurance because they had collateral risk — you still have a $500k asset to protect.
