Home Insurance Coinsurance vs. Deductibles: What Could You Owe?

Three things get called "my share" on a Texas home policy, and they are three different jobs. Here is each one in dollars, with the story of a Spring rebuild that proved the point.

The answer

The deductible is the fixed amount you pay on a claim. The insurance-to-value condition, which most people call coinsurance, is a promise to insure the home for enough of its rebuild cost, usually at least 80 percent, and breaking it cuts what the policy pays on a partial loss. An insured copay is a separate option on some newer quotes where you pay a percentage of the claim after the deductible. Put all three on paper before you buy. The right share is the one you can write the check for the morning after.

Three words, three jobs

  • Deductible

    A deductible is the amount of a claim that you must pay yourself, and you might have a different deductible for each type of coverage. Around Houston the wind and hail deductible is usually a percentage of the dwelling limit, so a 2 percent deductible on a 500,000 dollar home is 10,000 dollars before the policy pays a cent. Work the math in wind and hail deductible percentages.

  • Coinsurance, the insurance-to-value condition

    Home policies rarely print the word coinsurance. The promise sits in the loss settlement conditions. Most companies require you to insure your house for at least 80 percent of its replacement cost, and some require 100 percent. Carry less, and on common forms a partial loss is paid in proportion to what you carried, or at actual cash value if that is more, and the rest is yours. The rebuild number is the whole game, and rebuild has nothing to do with purchase price or market value. The glossary covers the coinsurance condition in full.

  • Insured copay

    A newer line on some quotes. After the deductible, you pay a chosen percentage of what remains and the carrier pays the rest. Some versions carve out a total loss by fire. The endorsement wording decides every detail, so read it before you accept it.

What could you owe, one loss three ways

Say the home would cost 500,000 dollars to rebuild, and a tree takes the roof and two rooms, a 100,000 dollar covered loss. Here is your share under three contracts.

  • Insured to value, 2% deductible

    Dwelling limit
    $500,000
    Deductible
    $10,000
    Share after deductible
    $0
    Insurer pays
    $90,000
    You pay
    $10,000

  • Insured at $300,000, 2% deductible

    Dwelling limit
    $300,000
    Deductible
    $6,000
    Share after deductible
    $25,000
    Insurer pays
    $69,000
    You pay
    $31,000

  • Insured to value, 5% deductible, 30% copay

    Dwelling limit
    $500,000
    Deductible
    $25,000
    Share after deductible
    $22,500
    Insurer pays
    $52,500
    You pay
    $47,500

Hypothetical figures. The underinsured home shows the common-form proportion rule, 300,000 carried against the 400,000 the condition requires, so the policy pays 75 percent of the loss before the deductible. The copay is shown as these options are commonly written. Your policy's deductible, condition, and any copay endorsement decide the real numbers.

One loss, three checks. The deductible is the share everyone sees on the quote. The other two are the shares people find out about at claim time.

The number you think your house is worth

A family in Spring bought their home in 2002 for about 300,000 dollars, and for years that was the number in their heads. Then came the night of June 21, 2023, when a line of severe thunderstorms set the highest wind gust ever reported at Bush Intercontinental Airport, 97 miles per hour, and flipped a small plane upside down at Hooks Airport, minutes from our office. Four or five trees came down on the house. The rebuild on the home alone came to more than 427,000 dollars, before their belongings and the months of living somewhere else. Part of that cost was an engineer, because a rebuild costs what it costs to put the house back today, to current code, with twenty years of inflation attached, and what the home is worth never enters the math.

They had sat with me before the storm and trusted the rebuild number over the purchase price. Had they insured the house for the 300,000 dollars they believed it was worth, the policy would have stopped at its limit, and the rest of the rebuild would have been theirs.

There is no good way to write a home far under or far over the rebuild number. Under, and the claim breaks the family. Over, and you pay for coverage the house cannot use. The only way a client stays with us for years is when we do right by them, and on the Gulf Coast an agency that works any other way does not last.

The copay and the closing table

NOAA has had an El Niño Advisory in place since this fall, with a strong one likely into early 2027, and El Niño generally lessens hurricane activity in the Atlantic. New carriers read the same forecast and move in while the Gulf is quiet, and some of their quotes carry options Houston has rarely seen. One lets a household with a mortgage take a 5 percent deductible and add a 30 percent copay. The price can look wonderful. On a 600,000 or 700,000 dollar home, the share after a large loss does not.

In our experience, lenders check the dwelling limit and the deductible and are not looking for a copay line. We meet buyers who accepted a copay to get a quote low enough to close, found it at their first review with us, and removed it the same day. It was a purchase made to close on a house, and it had nothing to do with what the family could carry. Be wary of copays unless you are the household that knows, understands, and values that kind of flexibility, and can write the check. Put the copay question on your list in when to buy home insurance before closing.

The words we mix up at the kitchen table

Insurance is contract language, and the words matter. "I had a flood," when water backed up from a drain. Flood is a separate policy, and backup depends on an endorsement. "My whole house collapsed," when a wall cracked. Collapse is its own covered cause with its own rules. After a storm we hear from households that never lost power asking to file for a refrigerator of food. Insurance is for the sudden, the unforeseen, and the catastrophic. That is why I ask clients to call us before they open a claim, so we can describe what happened accurately, or send a specialist to confirm it. The last thing you want is a claim opened on the wrong words.

The three words in this article get mixed up the same way. Copay, coinsurance, deductible. One client reading quickly saw a 5 percent next to the roof and took it for a discount on a new roof. It was her wind and hail deductible. That was a hard conversation, we walked through it slowly, and she left feeling heard. Service is having someone sit with you and look at what matters to you.

Before you buy

If the premium is hard to pay, the coverage I cut to fix it will make the claim impossible to afford.

You deserve a brokerage that shows you every share on paper before you buy, and tells you what the lower price asks of you.

Questions readers ask

Does my Texas home policy have coinsurance?

Most do not print the word. The condition is insurance to value, and TDI says most companies require at least 80 percent of replacement cost. Check the loss settlement condition on your policy and the rebuild number on your declarations page.

What happens if my home is underinsured when I have a claim?

On common forms a partial loss is paid in proportion to what you carried, or at actual cash value if that is more, and then the deductible comes off. On a total loss the dwelling limit is the ceiling, whatever the rebuild costs.

Is an insured copay the same as a deductible?

No. The deductible is a fixed amount off the top of a claim. A copay, on the quotes that offer one, is a percentage of what remains after the deductible, and the endorsement decides which losses it applies to.

Will my lender catch a copay or a low dwelling limit?

Lenders check the dwelling limit against the loan and the deductible against their guidelines. In our experience they are not looking for a copay line. Review the policy before closing, when you can still change it.
