Wind, hail and flood: insuring a first home on the South Carolina coast

Why insurance belongs early in your planning

For a family buying in Charleston, Beaufort, Horry or Georgetown County, insurance can change what a home truly costs each month. Your lender adds the yearly premium to your escrow, and that amount counts toward your debt-to-income ratio. SC Housing's program guide caps that ratio at 45% with automated approval. A large premium can therefore affect not only your budget but also whether the loan is approved.

We would encourage you to request insurance quotes on any coastal home you are serious about while you are still inside your inspection or due-diligence period, not in the last week before closing.

Three kinds of risk, and who covers each

The wind pool, explained plainly

The South Carolina Wind and Hail Underwriting Association is a market of last resort for wind and hail coverage in a designated coastal territory. The South Carolina Department of Insurance describes it this way: it exists for property owners who cannot find coverage in the standard market, and its rates are higher than standard rates. The property must meet eligibility rules and be properly maintained.

The Department's advice is to shop standard insurers first. If a standard company will write your homeowners policy without wind, an agent can pair it with a wind pool policy. You apply through any licensed agent.

Watch the deductible, not just the premium

According to the Department of Insurance, deductibles vary by company, and some insurers offer an optional deductible that applies only to wind or hail losses. When you compare quotes, ask each agent for the wind or hurricane deductible in dollars, not only in words. A low premium paired with a large storm deductible may not be the bargain it seems. Keep in mind that SC Housing assistance cannot be set aside for future repairs, so savings for a deductible must come from your own budget.

Flood insurance: separate policy, separate rules

The Department of Insurance notes that most homeowners policies will not cover damage from flooding or rising water, and that homeowners generally need a National Flood Insurance Program policy for that protection. Private flood policies also exist in some areas.

FEMA's guide for real estate professionals sets out the points buyers most need:

• Required in high-risk zones. If the home is in a special flood hazard area and your loan is government-backed, your lender will require flood insurance. Lenders may require it elsewhere too.
• No waiting period at closing. A new flood policy usually takes 30 days to take effect, but there is no waiting period when it is bought in connection with making a mortgage loan.
• Assumable. A seller can transfer an existing flood policy to the buyer. Ask whether the seller has one; it may be worth comparing with a new quote.
• Not only a coastal concern. FEMA reports that almost one-third of flood insurance claims from 2014 to 2024 came from outside the mapped high-risk areas.

That last point applies well inland. Low-lying parts of the Midlands and the Pee Dee have flooded in past storms. Even where a lender does not require coverage, we would ask you to think carefully before declining it.

Help with storm-proofing: the SC Safe Home grant

The Department of Insurance runs SC Safe Home, a grant program that helps owner-occupants strengthen homes against wind. It lists eligible coastal counties as Beaufort, Berkeley, Charleston, Colleton, Dorchester, Florence, Georgetown, Horry, Jasper, Marion and Williamsburg. Current maximum awards are:

The home must be a single-family, freestanding primary residence with an active homeowners policy and no prior storm damage or claim payouts. Award amounts also depend on project cost and household income. Applications open in cycles, twice a year, and the program was not taking applications when we last checked. The Department advises not to schedule a wind inspection until you have applied, because inspectors must come from its approved list.

This is a program to use after you own the home, not a source of down payment. Still, a stronger roof can matter to your insurer, so it is worth knowing about while you shop.

A South Carolina tax tool for storm costs

South Carolina allows a catastrophe savings account. According to the Department of Insurance, residents who own a single-family home that is their legal residence for property tax purposes may deduct contributions from state taxable income. Interest is tax-free, and qualified withdrawals can pay deductibles and uninsured hurricane, flood or wind losses after the governor declares an emergency. The account must be labeled as such, held at a chartered bank, and limited to one per taxpayer.

Because eligibility follows legal residence status, this pairs naturally with the 4% legal residence application.

Your right to choose an agent

South Carolina law requires your lender to ask which insurance agent you prefer, just as it asks about your closing attorney. You are free to use an independent agent who can quote several companies, which is often helpful on the coast.

A short checklist for coastal buyers

1. Ask the seller for the flood zone, any flood policy, and the insurance claims history.
2. Get homeowners, wind and flood quotes during your due-diligence period.
3. Write down each deductible in dollars.
4. Give the final premiums to your lender so your payment estimate is accurate.
5. After closing, file for the 4% ratio and consider a catastrophe savings account.

When you are ready to see which assistance programs fit your coastal county, please check your eligibility.
