Making sure you have enough coverage

From Home Insurance in Kentucky: What It Costs and What Actually Covers You

The most consequential number on your policy is your Coverage A limit, and the most common way it goes wrong is setting it to your home's market value or your mortgage balance.

Neither is right. Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices. Market value includes land, which does not burn and does not blow away. Your mortgage balance is a financing number with no relationship to construction cost.

In Kentucky, rebuild cost runs well above market value

This is the reverse of the coastal states, and it is where Kentucky homeowners get hurt.

Kentucky's median home price is $279,900. Rebuilding a 2,000 square foot home runs roughly $420,000 at the state's midpoint construction cost. That is $140,000 more than the median Kentucky house sells for.

In Hawaii or California, land is most of the price, so insuring to market value means over-insuring. In Kentucky, land is cheap and construction is not. If you set Coverage A to what you paid for the house, or to what the county assessor says, or to what a real estate site estimates, you are very likely underinsured — and the coinsurance arithmetic below shows exactly what that costs.

Working a real Kentucky example

Rebuilding in Kentucky runs roughly $210 per square foot — the midpoint of a published $150 to $270 band covering materials, labor, and general contractor overhead and profit, excluding land.

On a 2,000 square foot home:

  • 2,000 x $210 = $420,000 to rebuild

Take the band seriously:

  • At $150/sq ft: $300,000
  • At $270/sq ft: $540,000

A $240,000 spread on the same house. And a limitation worth stating rather than burying: this source publishes coarse regional cost bands, and Kentucky shares its exact $150-$270 range with Alabama, Florida, Louisiana, Tennessee and Texas. It is a regional Southern band applied to Kentucky, not a Kentucky-specific survey. No Kentucky building department or insurance regulator publishes a competing figure to check it against.

Two other national construction-cost series put Kentucky at $158 and $147 per square foot — materially lower. They are not hidden here and they are not averaged in either, because they are measuring a narrower quantity: both land near a $162 national average, which is the construction-cost figure that excludes general contractor overhead and profit. Your rebuild will include a general contractor's overhead and profit. The higher figure is the right one for insurance purposes.

The practical instruction: get an actual replacement-cost estimate for your specific home from your carrier or an independent estimator. Use the per-square-foot rule to sanity-check a number someone hands you, not to set your policy.

The 80% coinsurance rule, and what a shortfall does to a partial claim

Most homeowners policies contain a coinsurance provision requiring you to insure the dwelling to at least 80% of its full replacement cost. Fall below that and the insurer does not merely cap your payout at your limit — it reduces every partial claim proportionally.

Work it on the Kentucky example. Full replacement cost $420,000, so the 80% threshold is $336,000. Suppose you carry the $300,000 reference limit — which looks generous next to a $279,900 median home price — and a storm does $100,000 of damage.

Your limit is three times the loss. It feels safe. It is not:

  • $300,000 carried / $336,000 required = 0.893
  • 0.893 x $100,000 = $89,286
  • Then subtract your wind/hail deductible — $3,000 at 1% of $300,000
  • Net payment: about $86,286 on a $100,000 loss

You are roughly $13,700 short on a claim well inside your policy limit, entirely because Coverage A was set too low.

Push the shortfall further and it compounds. Carry $250,000 — roughly what a buyer who insured to their purchase price might have — on the same $420,000 home:

  • $250,000 / $336,000 = 0.744
  • 0.744 x $100,000 = $74,405
  • Minus $2,500 (1% of $250,000) = about $71,905
  • Roughly $28,100 short on the same loss

None of this is visible until you file.

Two endorsements worth asking about by name

  • Extended replacement cost — pays a stated percentage above your Coverage A limit (commonly 25% to 50%) when rebuilding costs more than the estimate. After a wide-area tornado or hail event, local contractor demand spikes and material prices move. This endorsement exists for exactly that.
  • Ordinance or law coverage — the cost of rebuilding to current code rather than as originally built.
