The 71% Underinsurance Trap
A TDI HO-B policy on a 1962 Houston bungalow shows Coverage A of $400,000. The insured's contractor and two independent estimators agree that the full replacement cost of the dwelling immediately before the loss was $560,000. A May hailstorm damages the roof, gutters, condenser unit and screens. The adjuster's line-item estimate is $90,000 replacement cost, of which $18,000 is depreciation. The policy carries a 2% wind/hail deductible on Coverage A ($8,000). The carrier paid $64,000 and told the insured the remaining $18,000 would be released when repairs are complete. Contents claims total $9,000, including $4,500 of the insured's home-based printing equipment; the form has a $2,500 special limit on business property on the residence premises.
1. Is the insurer's $64,000 payment correct? Work through the HO-B loss settlement provision and state what the adjuster should actually demand.
Read the worked answer
No. The payment ignores the 80% insurance-to-value condition.
Step 1 - test the condition. 80% of full replacement cost = 0.80 × $560,000 = $448,000. The limit carried is $400,000, which is only 89.3% of the required amount (or 71.4% of full replacement cost). The insured is underinsured, so the policy's alternative - not the full replacement-cost measure - controls.
Step 2 - compute the alternative. The form pays the larger of:
- (a) Actual cash value of the damage: $90,000 − $18,000 = $72,000; or
- (b) The proportion the limit bears to 80% of full replacement cost, applied to the loss: ($400,000 ÷ $448,000) × $90,000 = 0.8929 × $90,000 = $80,357.
Step 3 - apply the deductible. $80,357 − $8,000 = $72,357 payable.
What this means strategically. The carrier underpaid by $8,357 ($72,357 − $64,000). But there is no $18,000 of recoverable depreciation waiting to be released: once the 80% condition fails, the proportional settlement is final, and completing repairs does not restore replacement-cost treatment. The adjuster's real leverage is the $8,357 underpayment plus any missed or under-scoped line items - not a holdback that will never be paid. Promising the client the depreciation would be a serious misrepresentation of the policy.
2. The insured plans to replace the 3-tab roof with architectural shingles and a code-required ice barrier, and wants the carrier to pay the upgrade. The carrier says it will pay 3-tab only. Who is right, and what coverage might close the gap?
Read the worked answer
The carrier is largely right, with one nuance.
Measure of loss. Both branches of the settlement provision are anchored to repairing or replacing with materials of like kind and quality. Because the 80% condition fails, the measure is the proportional formula, but the base is still a like-kind-and-quality repair. Aesthetic upgrades (architectural shingles where 3-tab was there) are not owed and should not be presented as owed - that is the kind of padding that destroys the adjuster's credibility on the legitimate items.
The nuance. If the local code now permits only architectural shingles, or requires a different underlayment or decking, the replacement is no longer an upgrade - it is the like-kind repair in that jurisdiction. Then the item belongs in the estimate and the carrier's 3-tab figure is simply wrong.
Code items. Code-required construction triggers ordinance or law coverage, typically a stated percentage of Coverage A (commonly 10%), which is a separate bucket subject to its own limit and applied consistently with the coinsurance proportion. The adjuster should identify which line items are code-driven and route them there rather than inflating the general repair line.
Practical move: get a written code citation from the local building official, attach it to the estimate, and re-submit the code items under the ordinance-or-law limit rather than arguing about shingle aesthetics.
3. Compute the contents payment and explain the basis of valuation and the effect of the special limit.
Read the worked answer
Valuation basis. Coverage C pays actual cash value unless the insured bought the replacement-cost contents endorsement. Nothing in the file suggests she did. So the $9,000 of claimed items must be reduced to ACV by depreciation based on age and condition - the adjuster needs purchase dates and photos, not the insured's original receipts alone.
Special limit. The form caps business property on the residence premises at $2,500. The $4,500 printing equipment is therefore recoverable only up to $2,500. That sublimit is not subject to negotiation and is not restored by the endorsement unless the endorsement expressly increases it.
Arithmetic. Non-business items: $9,000 − $4,500 = $4,500 (then depreciated to ACV). Business items: capped at $2,500 (then depreciated to ACV). Maximum exposure at claimed values = $7,000, and realistically less after ACV depreciation.
Deductible. The $8,000 wind/hail deductible has already been applied once to this occurrence; it should not be applied a second time to the contents portion. Watch for the carrier re-applying it - that is a common and correctable error.
Client advice: document age and condition before asserting values, and do not bundle business equipment into the general contents schedule where the sublimit can be missed by the reviewer.
