1) Comparing Apples to Oranges
Many shoppers request quotes with different limits, deductibles, and endorsements—then choose the cheapest number. That “saving” is an illusion: it’s a different product. Carriers also round premiums differently and bundle discounts in distinct ways, so mismatched specs create noise.
Fix It
- Create a one-page Master Coverage Sheet with your standard limits, deductibles, and riders.
- Request 3–5 quotes using the same sheet for each carrier.
- Compare total annual cost for the same protection, not just monthly premium.

2) Cutting Liability Instead of Raising Deductibles
Liability is what protects you from the most expensive risks—lawsuits, injuries, and property damage. Slashing liability limits to save a few dollars is a false economy. You shift catastrophic risk back onto yourself.
Fix It
- Keep robust liability limits on auto and home/renters.
- Raise deductibles to an amount you can comfortably pay tomorrow.
- Consider a $1–2M umbrella policy for affordable extra protection.
3) Ignoring Discounts You Already Qualify For
Carriers reward risk-reducing behaviors, but credits often require proof. If you don’t provide documentation, the discount may never appear.
Fix It
- Ask for a written line-item discount sheet at every renewal.
- Submit photos/invoices for leak sensors, water shutoff valves, monitored alarms, dash cams, and ADAS safety features.
- Enroll in autopay, e-docs, and annual/semi-annual billing for admin discounts.
- Check affinity/group pricing via alumni or professional associations.

4) Treating Bundles as Automatic Savings
Bundling (auto + home/renters + life) often helps—but not always. Some carriers are competitive in auto, others in property. A bundle can mask an overpriced line.
Fix It
- Price the bundle and separate carriers with identical specs.
- Pick the lower total for the same coverage.

5) Filing Small, Frequent Claims
Frequent small claims can trigger surcharges or even non-renewal. Insurance is designed for big, rare events—not every minor dent or leak.
Fix It
- Self-pay minor losses if reasonable; use your policy for large or liability-heavy events.
- Increase deductibles and keep an emergency fund to cover small issues.
6) Letting Data Go Stale
Carriers price risk using facts: commute miles, garaging, security systems, roof age, drivers in the household, and more. Outdated info can inflate your premium or void discounts.
Fix It
- Update your agent after any change—new roof, job/commute, driver status, or security upgrades.
- Share VINs and device serials so credits attach correctly.
7) Over-Insuring Low-Value Items
Paying for collision/comprehensive on an older, low-value car or scheduling items below sub-limits can waste money.
Fix It
- Compare the annual added premium to the item’s value. If the math is poor, adjust coverage.
- For personal property, use riders where value justifies it; otherwise rely on base limits.
8) Skipping Loss-Prevention Devices
Cheap tech prevents expensive claims and may trigger credits. For homes, water damage is a top loss driver; for autos, crashes and theft dominate.
Fix It
- Install leak sensors, a smart water shutoff, and monitored smoke/CO alarms.
- Use dash cams and enable ADAS features; park in a garage where possible.
- Provide proof (photos/invoices) to your agent for discounts.
9) Never Re-Shopping at Renewal
Pricing shifts every year. If you let auto-renewals roll without checking, you may pay loyalty tax.
Fix It
- Start quotes 30–45 days before renewal with your Master Coverage Sheet.
- Request a retention review and ask the carrier to match a written competitor quote.
- Keep documentation ready—roof receipts, defensive driving certificates, and device photos.

10) Overlooking Exclusions and Gaps
People discover gaps after a loss—when it’s too late. Common blind spots: flood, earthquake, business/rideshare use, sewer backup, and high-value items exceeding sub-limits.
Fix It
- Read exclusions and add riders or separate policies where needed (e.g., flood insurance).
- Confirm business use coverage if you drive for delivery/rideshare or run a home business.
- Schedule jewelry, instruments, or cameras above sub-limits.
Heads up: Wear-and-tear and maintenance issues are not insurable events.
Quick Fix Checklist
Do This Before You Shop
- Build a Master Coverage Sheet (limits, deductibles, riders).
- Collect proofs: roof invoice, alarm certificate, leak sensor receipts, dash cam photos.
- List your mileage, garaging address, and drivers accurately.
When Getting Quotes
- Request 3–5 quotes with identical specs.
- Ask for a line-item discount sheet from each carrier.
- Compare the total annual cost (not just monthly).
After You Bind
- Set reminders for device maintenance (batteries, monitoring subscriptions).
- Store all documents for future re-shopping.
- Schedule an annual review 30–45 days before renewal.
Negotiation Scripts
“Please share a line-item discount sheet and confirm all device, bundle, claims-free, affinity, billing, and retention credits applied.”
“Here’s a competitor quote with the same limits and deductibles. Can you match or beat the total? If not, what retention offer is available today?”
FAQs
What is the #1 money-waster in insurance?
Mismatched comparisons. People choose the “cheapest” quote even though the limits/deductibles differ. Always compare identical specs.
Is telematics worth it?
For safe, low-mileage drivers—yes. Start with a trial quote and enroll if the projected savings look meaningful.
When should I raise deductibles?
When you have an emergency fund to cover them tomorrow. Higher deductibles reduce premium while preserving strong liability limits.
How often should I re-shop?
Every renewal cycle (annually) or after major life changes—move, marriage, new car/home, roof replacement, or improved credit.
