Underinsurance happens when your insurance coverage isn't enough to fully protect you from financial burdens, leaving you paying out-of-pocket for expenses.

It's more common than you think, and homeowners don't realize they're underinsured until something unexpected happens. Therefore, it's important that you regularly review your insurance policies and make sure you're not caught off guard if disaster strikes.

What causes underinsurance

The main reason behind underinsurance is a combination of factors: misunderstanding policy details, failing to update coverage amounts regularly and underestimating the replacement value of their possessions.

Homeowners assume their policy covers all risks, without realizing that certain events, such as floods or earthquakes, require separate insurance coverage.

What's more, when you renovate your home by remodeling the kitchen, adding a bathroom or finishing a basement, your home's value may increase. If you don't update your insurance policy to reflect these changes, you'll be left with a gap between your coverage limit and the actual cost to restore your home in case of a loss.

According to recent data, two-thirds of US homeowners are underinsured because their policy limits have not kept pace with rising construction costs and luxury upgrades1.

4 Tips to avoid underinsurance

1. Review your policies every year

You can avoid the financial setbacks associated with underinsurance by proactively reviewing your insurance policies. Schedule annual check-ins with your insurance agent and keep records of any changes to your home, valuables or lifestyle to ensure your policies always match your needs.

2. Know your coverage limits and details

Check if your policy limit is significantly lower than the estimated cost to rebuild your home or replace your belongings. If it is, you're underinsured.
It's important to note that inflation and changes in the housing market directly affect the cost of rebuilding your home. You can hire a professional appraiser to perform a detailed assessment and provide an evaluation based on current construction costs and market conditions.

3. Understand what's excluded in your policy

Homeowners' insurance policies often have exclusions that leave homeowners exposed to certain risks. Standard policies typically don't cover damages from natural disasters such as floods, earthquakes and landslides, which require separate insurance policies. Normal wear and tear, neglect and maintenance-related issues also fall outside coverage.

4. Take inventory of your belongings

Take inventory of your personal possessions and estimate their replacement value. Ensure your policy's personal property coverage is sufficient to replace all your items. You can also consider additional endorsements for high-value items such as jewelry, art and antiques.

Know your resources

To safeguard your home and financial wellbeing, we encourage you to find a local insurance agent who can review your policies at no cost. This proactive step will help you understand your coverage better, identify any gaps and ensure you and your family remain fully protected against life's uncertainties.

Don't wait for things to go wrong — act now and be ready to face the unexpected with confidence.
