1) Replacement cost vs. market value (this is the big one)

Home insurance is usually based on the cost to rebuild—not what the home would sell for. If limits are off, you can feel it at claim time.

What to review:

• Is the dwelling limit based on a replacement cost estimate?

• Are renovations and upgrades reflected (kitchen, baths, roof, electric)?

• Does the policy have any special requirements to receive full replacement cost?

---

2) Water backup / sewer backup coverage

Many homeowners assume this is included. Often it’s optional and needs to be added.

What to review:

• Is water backup included?

• What is the limit?

• What situations trigger coverage (every carrier can differ)?

---

3) Flood vs. homeowners insurance (not the same thing)

A standard homeowners policy typically does not cover flood (rising water). Flood coverage is generally separate.

What to review:

• Your location risk (even outside higher-risk zones)

• Basement exposure and what is/isn’t covered

• Whether flood coverage makes sense for your home and comfort level

---

4) Valuables: jewelry, watches, collectibles, and more

Many policies have category limits unless certain items are scheduled.

What to review:

• Do you have jewelry/watches that should be scheduled?

• Any fine art, collectibles, musical instruments, or specialty items?

• Do you have current appraisals/receipts saved?

---

5) Liability limits (and whether umbrella insurance makes sense)

Liability helps protect you if someone is injured and you’re found responsible.

What to review:

• Is your liability limit strong enough for your household and lifestyle?

• If you have a pool, trampoline, teen drivers, or higher assets, ask about umbrella coverage

• Make sure home/auto limits align if adding an umbrella

---

6) Loss of use (additional living expense)

If your home is unlivable after a covered loss, this can help with temporary housing and related expenses.

What to review:

• Is the limit realistic for local rental costs and your household needs?

• Do you understand what must happen for coverage to apply?

---

7) Deductibles (and any special deductibles)

Low premium + high deductible can be a painful surprise if a claim happens.

What to review:

• Your standard deductible amount

• Any separate deductibles shown on the policy (ask your agent to point them out)

• Choose a deductible you can comfortably afford

---

Quick Summary

Before you finalize a homeowners policy, confirm:

• Replacement cost and dwelling limit make sense

• Water backup coverage is addressed

• Flood risk is reviewed (and coverage discussed if appropriate)

• Valuables are handled correctly

• Liability is strong enough (and umbrella considered)
