Why rebuild cost matters more than market value
The single biggest mistake homeowners make is insuring their home for its market value instead of its rebuild cost. In a hot real-estate market, market value can be 50–100% higher than rebuild cost — leading you to over-insure and pay too much in premiums. In a depressed market, rebuild cost can be higher than market value — leaving you under-insured if the home is destroyed.
The four core coverages
- Dwelling: pays to rebuild the structure. Should equal local rebuild cost × square footage.
- Other structures: typically 10% of dwelling — covers detached garages, sheds, fences.
- Personal property: typically 50–70% of dwelling — covers furniture, electronics, clothing.
- Liability: pays if someone is injured on your property. $300,000 is standard; $500,000–$1M costs only marginally more.
Actual Cash Value vs Replacement Cost
Always choose replacement cost for personal property. Actual Cash Value (ACV) pays only what items are worth after depreciation — meaning a 5-year-old TV that cost $1,000 might be valued at $200. Replacement cost pays what it actually costs to buy a new equivalent.
If you live in a flood zone, you need separate flood insurance — standard home policies exclude flooding. The National Flood Insurance Program (NFIP) offers policies up to $250,000 for buildings and $100,000 for contents.
Frequently asked questions
Should I insure my home for market value or rebuild cost?
Rebuild cost. In hot markets, market value can be 50-100% higher than rebuild cost (land isn't insured). In depressed markets, rebuild cost can exceed market value. Insure for what it costs to rebuild the structure — your insurance agent can calculate this.
What is replacement cost vs actual cash value?
Replacement cost pays what it costs to buy a new equivalent item. Actual cash value (ACV) pays the depreciated value — a 5-year-old TV that cost $1,000 might be valued at $200 under ACV. Always choose replacement cost for both dwelling and personal property.
Does home insurance cover flooding?
No. Standard home insurance excludes flooding from rising water outside the home (rivers, storms, etc.). You need separate flood insurance through the National Flood Insurance Program (NFIP) or private insurers. Even homes outside FEMA flood zones can flood — 25% of flood claims come from low-risk areas.
What is loss of use coverage?
Pays for additional living expenses (hotel, restaurant meals, etc.) if your home becomes uninhabitable due to a covered event (fire, major water damage, etc.). Typically 20-30% of your dwelling coverage. Keep receipts — insurers reimburse actual expenses.
Does home insurance cover mold?
Sometimes. If the mold results from a covered event (burst pipe, roof leak from storm), it may be covered. If it results from neglect (slow leak you ignored, humidity), it usually isn't. Mold coverage is often capped at $5,000-10,000 — read your policy.
Should I file a claim for minor damage?
Often no. Home insurance is for catastrophic losses, not small repairs. Multiple small claims can lead to non-renewal. Pay out-of-pocket for damage under $1,000-2,000 (above your deductible). Save claims for true emergencies.
What is an umbrella policy?
Additional liability coverage ($1M-$10M) that sits 'on top of' your auto and home insurance. Kicks in after those limits are exhausted. Cheap — typically $150-300/year per $1M. Essential if you have assets to protect or earn above-average income (lawsuit target).

Common mistakes to avoid
- Insuring for market value instead of rebuild cost — over-insures in hot markets, under-insures in depressed markets
- Choosing actual cash value over replacement cost on personal property — payouts are dramatically lower
- Not buying separate flood insurance — standard policies exclude flooding
- Filing multiple small claims — can lead to non-renewal
- Not updating coverage after major renovations or home value increases
Pro tips
- Get a rebuild cost estimate from your insurer or a contractor — don't just insure for the purchase price.
- Install monitored security and fire alarms — typically saves 5-15% on premiums.
- Bundle home and auto insurance with one carrier — typically saves 10-25% on both.
- Raise your deductible to $1,000-$2,500 — saves 15-30% on premiums and discourages small claims.
- Once your net worth exceeds $500K, add a $1M+ umbrella policy — cheapest asset protection available.
