UpTrajectory Review

TheStreet's piece on home underinsurance cites a sobering data point: in a review of 74,000 California fire claims between 2018 and 2023, law professor Kenneth Klein found that more than 70% of insured homeowners were underinsured by an average of roughly 20%. That means most people who dutifully paid premiums discovered, after losing their homes, that their policy would not cover the full cost of rebuilding. Klein calls it a 'barely hidden nationwide crisis of underinsurance,' and the framing is apt — the gap is not a fringe problem affecting careless buyers. It is the default outcome for most policyholders, and it persists because the failure only becomes visible at the moment of maximum vulnerability.

For small-business owners, this is not just a homeowner concern — it is a business continuity warning. Many operators run their companies out of their homes, store inventory or equipment in garages and basements, or hold personal assets that backstop their business. If a fire or flood destroys the home and the payout falls 20% short of rebuilding costs, the business loses its physical base, its collateral, and often its owner's financial cushion in one event. The article notes that about 90% of owner-occupied U.S. homes carry insurance, which creates a false sense of security. Coverage existing is not the same as coverage being adequate, and the difference only surfaces after the loss.

The flood section is where the article makes its most useful distinction. Standard homeowners policies categorically exclude flood damage — defined as water entering from the ground up — and require a separate flood policy. FEMA data cited in the piece shows that one inch of standing water can cause approximately $25,000 in damage, and the average flood claim payout from 2020 through 2024 was $82,614. Nearly 99% of U.S. counties experienced at least one flood in the past 20 years. This is not a coastal-elite problem. It is a near-universal exposure that most homeowners, including those running businesses from their properties, have simply chosen not to address.

Where we find the article thin is on causation. It attributes underinsurance partly to homeowners not reading the full policy contract, which is technically true but lets insurers and agents off too easily. Rebuilding costs have risen sharply with inflation and construction labor shortages over the past several years, and many policies were written before those increases. Insurers have incentives to keep premiums competitive by setting replacement-cost estimates conservatively. The article also does not explore whether agents have a fiduciary duty to flag coverage gaps, or what regulatory scrutiny exists. The 'read your policy' advice is correct but insufficient — most homeowners lack the expertise to evaluate whether a replacement-cost estimate is realistic even if they read every page.

The second-order effect worth watching is the squeeze on small-business owners who use home equity to fund operations. If a home is underinsured and destroyed, the owner may still owe a mortgage on a property that no longer exists, with no equity to borrow against and no home office, workshop, or storage space to run the business from. The article's focus on homeowners' personal losses understates this compounding effect. Commercial property policies have their own gaps, but the home-based business owner who assumes their homeowners policy covers business equipment or inventory is often doubly exposed — business property is frequently excluded or capped at minimal amounts in standard policies.

What to do: pull your current policy and check the replacement-cost estimate against local per-square-foot construction costs, not the market value of your home. Ask your agent specifically about extended or guaranteed replacement-cost endorsements, which add a buffer above the stated limit. If you are in any flood-prone zone — and given that 99% of counties have flooded, that is nearly everyone — get a flood policy quote through the NFIP or a private insurer. If you run any portion of your business from home, confirm whether business property, liability, and loss of income are covered, and consider a home-based business endorsement or separate BOP. Do this before renewal season, not after the next disaster headline.

Takeaway: Most homeowners are underinsured by about 20% and standard policies exclude flood damage entirely — audit your coverage limits and flood exposure before renewal, not after a loss.
