Homeowners insurance is usually an afterthought — a box to check before closing. That's backwards: the policy you can get, and what it costs, is shaped by the inspection findings you're holding right now. This guide explains policy types in plain English, what standard policies cover and exclude, how roof age, electrical panels, plumbing, and claims history move your premium, the deductible and valuation choices that matter, and why you should shop for quotes during the inspection period, not after closing.

Policy types in plain English

  • HO-3 (the standard house policy). For a detached single-family home you own and live in. The dwelling is covered on an "open perils" basis — everything except what's explicitly excluded. The default policy for most buyers, and what lenders require.
  • HO-6 (condo policy). The association's master policy covers the building exterior and common areas; your HO-6 covers from the interior walls in — unit finishes, personal property, liability. Confirm what the master policy covers so you don't double-insure or leave a gap.
  • HO-4 (renters policy). Personal property and liability only, no dwelling. Worth knowing so you don't confuse it with what your new home needs.

Lenders require at least an HO-3 (or HO-6 for condos) as a mortgage condition — the loan doesn't fund without proof of coverage. That gives you a hard deadline: coverage must be bound before closing.

What's covered — and what's not

A standard HO-3 bundles:

  • Dwelling — the house itself, up to the policy's dwelling limit.
  • Other structures — detached garage, shed, fence, typically 10% of the dwelling limit.
  • Personal property — your belongings, typically 50–70% of the dwelling limit. High-value items (jewelry, art) often need scheduled endorsements above sublimits.
  • Liability — commonly $100,000–$500,000; the coverage most buyers undervalue.
  • Loss of use — extra living expenses if the home is uninhabitable after a covered loss.

Common exclusions buyers are surprised by:

  • Flood — never in a standard policy; that's a separate flood policy. Check FEMA flood maps during your inspection period.
  • Earthquake and earth movement — excluded unless you buy an endorsement. In sinkhole-prone regions, verify exactly what your policy says.
  • Wear and tear and neglect — insurance covers sudden, accidental events, not the slow roof leak ignored for three years.
  • Sewer backup — usually excluded unless you add a water/sewer backup endorsement, often just $25–$75/year and worth it on any home with a basement or older lateral.

How your inspection moves your premium

Insurers price risk, and your inspection report is a risk catalog. These findings commonly raise premiums or make a home hard to insure at standard rates:

  • Roof age and material. The biggest premium lever. Roofs over 15–20 years old (asphalt shingle) often face surcharges or actual-cash-value-only roof coverage; some insurers decline homes with roofs past 20–25 years. A new architectural shingle or metal roof can earn real discounts. Get the roof's age in writing during the inspection.
  • Electrical panels and wiring. Federal Pacific Stab-Lok and Zinsco panels make underwriters flinch — many insurers require panel replacement ($1,500–$3,000) before binding coverage. Knob-and-tube wiring has a similar effect. Get quotes with these facts disclosed — a quote assuming updated electrical isn't real.
  • Plumbing type. Polybutylene supply piping (late 1970s–mid-1990s homes) is a known failure risk; some insurers surcharge or decline. End-of-life galvanized steel raises similar concerns.
  • Distance to fire hydrant and station. "Protection class" ratings factor hydrant distance and response time. A rural home miles from the nearest station pays more than an identical one two blocks away. You can't change it — budget for it.
  • Claims history (the CLUE report). The Comprehensive Loss Underwriting Exchange tracks claims filed on the property, by any owner. Two water-damage claims in five years raise your premium regardless of how nice the renovation looks. Ask your agent to pull the CLUE report during the inspection period.
  • Other flags: wood shake roofs, unpermitted additions, pools and trampolines (liability), and certain dog breeds (liability exclusions vary by carrier).

Deductibles: the number that controls your premium

  • Standard perils deductibles run $500–$2,500. Raising $1,000 to $2,500 can cut the premium noticeably — but only choose a deductible you could pay tomorrow from savings.
  • Separate wind/hail and hurricane deductibles are standard in coastal states — often 1–5% of the dwelling limit, not a flat amount. On a $400,000 dwelling limit, a 2% hurricane deductible is $8,000 out of pocket. Read this line on every coastal quote.
  • Rule of thumb: insure for catastrophes, self-insure the small stuff — as long as the deductible is genuinely affordable to you.

Replacement cost vs. actual cash value

  • Replacement cost value (RCV) pays to rebuild or replace with new materials of like kind — no depreciation deduction. What you want on the dwelling.
  • Actual cash value (ACV) is replacement cost minus depreciation. A 15-year-old roof replaced under ACV pays a fraction of the new roof's cost — the rest comes from your pocket. Some insurers default older roofs to ACV; know which valuation your quote uses.
  • Extended/guaranteed replacement cost endorsements pay 125–150% of the limit (or the full rebuild cost) when construction inflation pushes rebuilds over your dwelling limit — worth considering in high-cost markets.

When comparing quotes, confirm the same valuation basis. A cheaper quote that's ACV on the roof isn't cheaper — it's less insurance.

Shopping tips: get quotes during the inspection period

  1. Start the day your inspection is scheduled, not the week before closing. You need real quotes — with roof age, panel brand, plumbing, and claims history disclosed — while you still have a contingency to renegotiate or walk away.
  2. Get at least three quotes from a mix: a captive agent, an independent agent, and one direct online quoter. Premiums for identical coverage routinely differ by 30%+ between carriers.
  3. Compare coverage, not just price. Line up dwelling limits, deductibles (including wind/hurricane), valuation basis, and endorsements. The cheapest premium with a 5% hurricane deductible and ACV roof is not the best deal.
  4. Ask about discounts: new roof, monitored security, smoke/CO detectors, water leak sensors and auto shutoff valves, bundling auto + home, claims-free history, higher deductibles.
  5. Disclose everything material. A policy bound on incomplete information — panel brand, roof age, the wood stove — can be voided or denied at claim time. The application is a legal document.
  6. Re-shop annually. An hour of comparison shopping each renewal routinely finds savings, especially after insurability upgrades like a new roof or panel.

What this guide does not cover

This is a buyer's orientation, not insurance or legal advice. It doesn't cover flood insurance in depth (separate program, own rules and waiting periods — start at FEMA's flood map service during your inspection period), landlord or vacant-home policies, umbrella liability, or your state's specific insurance regulations, which govern everything from hurricane deductible rules to non-renewal. Premium figures and underwriting rules vary by carrier and state — confirm real figures with licensed agents quoting the actual property. When a home has serious insurability flags, talk to an independent agent before removing contingencies.

Frequently asked questions

How much homeowners insurance do I need?

Your lender sets the floor — typically at least the loan amount — but rebuilding cost is the smarter target. Insure for what it would cost to rebuild the house (replacement cost), not the purchase price or land value. Underinsuring to save premium is a false economy that shows up exactly once: at claim time.

Can an insurer refuse to cover a house I'm buying?

Yes — based on roof age, flagged panels, polybutylene plumbing, claims history, or high-risk location. That's why you shop during the inspection period: learning at the closing table that only one expensive carrier will take the house is a bad surprise. A hard-to-insure home is telling you something about the home; use it in negotiation.

What's a CLUE report and how do I get one?

The Comprehensive Loss Underwriting Exchange is an industry database of property insurance claims — claims on the address, by any owner, typically seven years back. Your agent can usually pull it when quoting, and you're entitled to one free report per year yourself. Ask the seller to disclose prior claims too; the CLUE report verifies the answer.

Should I file small claims?

Usually no. A $1,200 claim against a $1,000 deductible nets $200 and puts a claim on the property's CLUE record, raising premiums for years. Common rule of thumb: if the loss is less than roughly twice your deductible, pay out of pocket. Save insurance for losses that would actually hurt.

Does homeowners insurance cover mold?

Sometimes, partially — typically only when mold follows a covered sudden event like a burst pipe. Mold from long-term leaks, humidity, or neglect is excluded as wear and tear, and many policies cap mold payouts (common sublimits $1,000–$10,000) unless you buy added coverage. Read the mold exclusion on your specific policy; don't assume.
