Before comparing insurance premiums on a Nashville short-term rental, convert any wind or hail percentage deductible into dollars using the base specified in the proposed policy. Then read the roof's loss-settlement terms separately. A smaller annual premium can come with a larger retained loss, and a deductible calculation alone does not show what an older roof might receive after depreciation.
For an STR buyer, this is a cash-reserve question as well as a coverage question. Complete the review with a licensed insurance professional who knows the intended rental operation. The examples below explain the arithmetic; they do not establish that a homeowners policy covers short-term rental use or that any particular loss will be paid.
Find the wind and hail deductible in the actual documents
Request the proposal, declarations, deductible endorsements and roof settlement provisions for the exact property and proposed insured. A summary saying “$2,500 deductible” may not answer what applies to a wind or hail loss. Ask which provision controls that event and whether a different deductible applies to the roof or another part of the property.
The NAIC's roof-coverage guidance specifically recommends checking for separate wind, hail and roof deductibles. It also cautions that coverage varies. The existence of a deductible is not proof that the underlying cause of damage is covered.
Keep the scope clear: this article addresses one part of an insurance review. The insurer still needs an accurate description of the rental activity, ownership, booking channels and property features. A policy selected for a different use should not be treated as suitable simply because its deductible is affordable.
A percentage of what?
The NAIC explains that a deductible can be a percentage of the home's insured value, rather than a fixed dollar amount. Read the actual base in the form. Do not automatically multiply the percentage by the purchase price, the contractor's estimate or the outstanding mortgage.
Consider an original hypothetical example: a Nashville-style rental has a $600,000 purchase price, but the proposed deductible provision uses a $480,000 dwelling limit as its base. At 2%, the calculation is $480,000 × 0.02 = $9,600. Neither the price of the real estate nor the size of an eventual claim changes that stated base in this illustration.
If the same percentage instead applies to a $600,000 insured limit at a later renewal, the deductible becomes $12,000. That is $2,400 more cash retained by the owner. These are assumed policy inputs, not quotes, typical Nashville terms or an argument for reducing coverage limits. Ask the insurer to explain the replacement-cost estimate and the coverage consequences before changing a limit.
Separate the deductible from roof depreciation
Tennessee's Department of Commerce and Insurance explains that actual cash value generally subtracts depreciation, while replacement-cost benefits address current replacement cost under the policy's terms. Its ACV-versus-replacement-cost guidance also notes that a replacement-cost claim may initially be paid at actual cash value, with additional reimbursement after supporting repair documentation. Qualification and payment conditions vary.
The following illustration isolates those differences. Assume a covered roof loss has an accepted $25,000 replacement cost, a $9,600 deductible and $5,000 depreciation. Assume no other limit, exclusion, coinsurance adjustment or roof schedule changes the calculation. Real claims require those additional terms to be checked.
Illustrative settlement basis | Calculated insurance payment | Owner's share of the $25,000 replacement |
|---|---|---|
ACV, with $5,000 depreciation not recoverable | $25,000 − $5,000 − $9,600 = $10,400 | $14,600 |
Replacement cost, after all assumed reimbursement conditions are met | $25,000 − $9,600 = $15,400 | $9,600 |
Replacement cost, if the initial payment withholds that $5,000 pending qualifying repairs | Initial $10,400; potentially another $5,000 later | Potential $14,600 funding gap before later reimbursement; final assumed share $9,600 |
The last row is a timing issue, not an additional permanent deductible. Confirm what is recoverable, what work or receipts are required, what deadlines apply and when reimbursement can occur. Do not treat money that may arrive after repair as cash already available to fund the contractor.
Use a short comparison sheet before choosing a proposal
Question | What to record |
|---|---|
Does the proposal address the intended STR operation? | The disclosed use and the insurer's applicable forms or endorsements. |
Is wind or hail covered, excluded or handled elsewhere? | The controlling coverage provision and any separate policy. |
Which deductible applies? | Percentage or dollars, calculation base and event-specific wording. |
How is the roof valued? | Replacement cost, ACV, schedule or limitation, with the relevant endorsement. |
What money could be needed before reimbursement? | Deductible, nonrecoverable amounts and any temporary repair-funding gap. |
Ask the professional to annotate the form numbers and dates beside each answer. If two proposals have different dwelling limits or roof settlement terms, they are not a clean premium comparison yet. Preserve the unresolved differences rather than choosing the cheaper number and assuming the rest matches.
Connect the insurance review to the property's acquisition budget
Keep a potential insured-loss cash need separate from routine maintenance and planned roof replacement. Insurance is not evidence that an aging roof needs no capital reserve. Review the roof's inspection findings, installation records and any known repair history alongside the proposed settlement terms.
Likewise, this deductible calculation says nothing about reimbursement for canceled stays or lost rental income. Those require a separate review of the applicable coverage, trigger and conditions. The companion site's Nashville STR operating-expense guide provides the broader budget context; keep a claim payment or speculative recovery out of recurring lodging revenue.
When comparing a Nashville acquisition, bring the written insurance proposal and property-condition records into the discussion with The Costigan Group's STR advisory team. The practical question is whether the purchase leaves enough liquidity for the risks you retain, after the coverage professional has explained what the contract actually offers.
