The single most common mistake in Texas homeowners insurance is insuring a house for what it is worth instead of what it costs to rebuild. Those are different numbers, they move independently, and getting it wrong only becomes visible after a total loss — the worst possible moment to discover a shortfall.
Market value is the wrong number
What you paid for your house includes the land. Land does not burn down. If your home is insured at its purchase price, you may be paying premium on value that is not at risk while carrying too little on the part that actually is.
The number you need is replacement cost: what it would cost, today, at current local labor and material prices, to rebuild your house from the slab up.
In some Texas markets replacement cost is well below market value. In others — older neighborhoods, small towns, areas where construction labor is scarce — rebuilding costs more than the house would sell for. Both situations are normal and both require you to actually check rather than assume.
Why Texas replacement costs moved so much
Construction costs in Texas rose sharply through the first half of this decade. Lumber, roofing materials, concrete and skilled labor all climbed, and after a major storm, local demand spikes and prices climb further. A dwelling limit set when you bought in 2018 and never revisited is very likely too low today, even if your policy has applied a small automatic inflation adjustment each year.
Those automatic adjustments are useful but they are blunt. They do not know that you finished the garage, added a covered patio, or that your county's labor market tightened.
The rest of the policy scales off that one number
Most homeowners policies set the other coverages as percentages of your dwelling limit, which means an incorrect dwelling limit quietly makes everything else wrong too:
- Other structures — detached garage, workshop, fence, barn — often around 10% of the dwelling limit.
- Personal property — everything inside — often 50% to 70%.
- Loss of use — somewhere to live while the house is repaired — often around 20%.
Run those percentages against your own limit and ask whether the results are plausible. If personal property comes out at $150,000, would that replace the contents of your house? For many households it is generous. For a family with a well-equipped workshop, musical instruments or serious tools, it is not.
Replacement cost versus actual cash value
This distinction is worth more money than almost anything else in the policy.
Replacement cost pays to replace what was damaged with new equivalent material. Actual cash value pays replacement cost minus depreciation for age and wear.
On a fifteen-year-old composition roof, the depreciated value can be a small fraction of what a new roof costs. Many Texas policies have shifted roofs specifically to actual cash value or to a roof payment schedule that steps down with age — sometimes at renewal, sometimes with a notice that is easy to miss. Check which basis applies to your roof, then check whether personal property is settled on replacement cost or actual cash value, because the same logic applies to a ten-year-old sofa.
Extended and guaranteed replacement cost
Some policies offer an endorsement that pays above your dwelling limit if rebuilding costs exceed it — commonly an additional 10% to 50%. This exists precisely because of the scenario Texas produces regularly: a hailstorm or hurricane damages thousands of homes at once, local contractors are booked solid, prices jump, and everyone's carefully calculated limit turns out to be short.
The endorsement is usually inexpensive relative to what it protects against. Ask what it costs on your policy.
Liability is usually set too low by default
Personal liability often defaults to $100,000 or $300,000. That covers a guest's broken arm. It does not cover a serious injury lawsuit.
Raising liability limits is one of the cheapest changes available on a homeowners policy, because severe claims are rare. If you have a pool, a trampoline, a dog, or teenagers who have friends over, look at $500,000 and ask about a personal umbrella policy. An umbrella typically adds a million dollars of liability across your home and auto for a few hundred dollars a year.
What is not covered, no matter how high your limits are
- Flood. Excluded from standard homeowners policies and a separate purchase. In Texas, serious flooding regularly happens outside mapped high-risk zones, and flood policies commonly have a waiting period before they take effect. Buying once a storm has a name is too late.
- Normal foundation movement. Settling and soil movement in expansive clay — common across much of Texas — is generally excluded. Some policies cover foundation damage caused by a specific covered event such as a slab leak. The wording varies enormously between carriers.
- Maintenance. A roof that failed from age rather than a storm is a maintenance issue, not a claim.
A short annual review
Once a year, spend fifteen minutes on this:
- Does the dwelling limit still reflect current local rebuild costs?
- Have you made improvements the carrier does not know about?
- Is your roof settled at replacement cost or actual cash value?
- What is your wind and hail deductible in dollars?
- Are your liability limits still appropriate for your household?
- Do you have any coverage for flood?
That is the entire review. It is short, and it is the difference between a policy that works and a policy that technically exists.
