What is the 80% real? Insurance companies will require the policyholder to cover 80% of the deductible upfront. Thanks for holding mortgages require the policyholder to about 80% of the premiums into the mortgage. Insurance companies require the 20% of the replacement cost of the property be set at the deductible. Insurance companies will require the policyholder to take 80% of the replacement cost of the entire property in coverage or they will reduce the reimbursements buy a proportion amount them out.

The 80% rule mentioned in your question refers to an insurance concept called "coinsurance." It states that insurance companies will require policyholders to carry coverage for at least 80% of the value of the property they are insuring. Let's break down the different aspects of the 80% rule:

1. Deductible: When you file a claim, the deductible is the amount you need to pay out of pocket before your insurance coverage kicks in. If you have an 80% coinsurance clause, the insurance company may require you to pay 80% of the deductible upfront.

2. Premiums: Premiums are the payments you make to the insurance company to maintain your policy. Some mortgage lenders may require you to include insurance premiums in your monthly mortgage payments. If this applies to your situation, you may need to pay approximately 80% of the premiums along with your mortgage payment.

3. Replacement Cost: Insurance companies often set a replacement cost for the property, which is the estimated cost to rebuild or repair the property in case of damage or loss. In the context of the 80% rule, the insurance company requires you to have coverage for at least 80% of the replacement cost. If the coverage falls below this amount, the insurance company may reduce the reimbursements for any claims you file.

To summarize, the 80% rule generally means that insurance companies require policyholders to maintain coverage for at least 80% of the property's value or replacement cost. If you don't meet this requirement, the insurance company may reduce the amount they reimburse for claims based on the proportion of coverage you have. It is always best to consult your specific insurance policy and company for detailed information about the application of the 80% rule.
