Short-term rental insurance: what AirCover doesn't cover

A washing-machine hose let go behind the wall of my ground-floor flat on a Tuesday I wasn't hosting. Water down two rooms, buckled flooring, a repair quote of $9,400, and eleven weeks with the calendar blocked. AirCover paid $0 — no guest was involved, so it wasn't their problem. My home insurer paid $0 too, for the opposite reason: the policy had a clause voiding cover the moment the flat was let to paying guests, and I'd been on Airbnb for two years. I was uninsured and hadn't known it since the day my first guest checked in.

This is the post I wish someone had put in front of me before that Tuesday. What AirCover actually is (a reimbursement program, not insurance), why the policy you think covers the building already voided, the five things a real short-term rental policy pays for, and what proper cover costs per year in the US, UK, and EU.

AirCover is a reimbursement program, not an insurance policy

Airbnb advertises "up to $3M in damage protection" and "$1M in liability" on every booking, free, automatic. The number is real. The framing is misleading, and the framing is the whole problem.

AirCover for Hosts is a contractual reimbursement, not a regulated insurance contract. That distinction sounds like lawyer noise until you file a claim and hit the conditions:

• It only pays for guest-caused damage. A burst pipe, a roof leak, faulty wiring, a kitchen fire that started in your own appliance — none of it is a guest's fault, so none of it is covered. My washing-machine hose was a textbook $0.
• It's Airbnb-only. A guest who booked through Booking.com, Vrbo, or your direct site is not an Airbnb guest. AirCover does not apply to them at all. If you're multi-platform, most of your bookings sit outside it.
• It pays after depreciation. A four-year-old TV is not reimbursed at replacement cost. The resolution team applies a "useful life" factor and pays a fraction. In practice AirCover settles 60–85% of approved claims.
• The clock is 14 days. Without dated evidence filed inside the window — ideally check-out photos — the refusal rate climbs steeply.
• Loss of income is not in it. If damage blocks your calendar for two months, AirCover reimburses the repair (if guest-caused) and nothing for the eleven weeks of bookings you couldn't take.

The liability limb is the one exception worth naming: Airbnb's "Host liability insurance" up to $1M is underwritten insurance, not just a reimbursement. But it's still Airbnb-only, still a backstop with its own exclusions, and it evaporates the second a guest arrives through any other channel. For the full mechanics of the damage side and how it stacks against Booking.com and Vrbo, I wrote a whole post: AirCover vs Booking.com damage deposit. This post is about the layer underneath all of it — the policy AirCover was never meant to replace.

The homeowner policy you think you have already voided

Here's the part that catches almost everyone. You bought a home, you have buildings-and-contents cover, you assume the building is protected. Then you list it on Airbnb, and somewhere on page nine of your policy there is a sentence that just switched your cover off.

Standard personal policies are priced for one risk profile: an owner-occupier, or a long lease to a single tenant. They carry one of two exclusions that STR use trips:

• Business / commercial use exclusion. Renting nightly to strangers is a commercial activity. Most homeowner policies exclude losses "arising from any business conducted on the premises". A fire during a paying stay can be denied on that clause alone.
• Transient / short-term occupancy exclusion. Even a landlord policy — the "buy-to-let" or dwelling policy you'd use for a 12-month tenant — typically excludes lets under a threshold (often 30 or 90 days). A three-night Airbnb booking is exactly the occupancy they wrote out.

The cruelty is the timing. Nothing fails until you claim. You pay premiums for two years, feel covered, and discover the exclusion in the denial letter after the worst week of your hosting life. Insurers investigate the property's use during a large claim; a listing screenshot with your address is all it takes.

There's a mortgage angle too. Many mortgages require the property to be insured and forbid short-term letting without lender consent. Running an undeclared STR can breach both the insurance and the loan at once. Declaring the use — to your insurer and, where required, your lender — is not optional paperwork. It's what keeps the cover valid.

The five coverage layers a real policy has

A purpose-built short-term rental policy isn't one product; it's a stack of coverages priced for the way you actually use the property. Here's what each layer does, and where AirCover leaves you exposed.

The two rows hosts underrate are liability and loss of income, so take them in turn.

Liability is the one that can end you. A guest slips on wet stairs and fractures a wrist. A child gets into an unfenced pool. Someone claims food poisoning. In the US, a bodily-injury suit routinely runs into six figures once medical costs and legal defence are added. AirCover's $1M liability covers this on an Airbnb stay — but the same guest on a Booking.com or direct booking has no host liability cover at all, because Booking.com provides none and your voided homeowner policy won't step in. Your own policy's liability limb covers the injury regardless of which platform sent the guest. If you have a pool or a hot tub, carry $2M, not $1M — the hot-tub ROI math looks very different once the liability premium is in it.

Loss of rental income is the one that quietly drains you. My eleven blocked weeks at even $120 a night was roughly $9,000 of bookings I couldn't take — on top of the $9,400 repair. A "loss of rental income" or "business interruption" rider pays your expected revenue while the unit is out of service after an insured event. AirCover pays none of it. For a full-time listing, this rider is often the single most valuable line in the policy.

What short-term rental insurance actually costs

Premiums vary more than any other host expense, because insurers price on location, revenue, guest count, and hazards (pool, wood stove, trampoline). But the ranges are knowable. Here's what a single unit typically costs to insure properly, as of 2026.

A few things move the number hard:

• Whole-home vs room. Letting a spare room while you live there is cheaper than a dedicated full-time listing.
• Revenue. Loss-of-income cover scales with your nightly rate and occupancy, so a $300/night listing costs more to insure than a $90 one.
• Hazards. Pool, hot tub, wood-burning stove, and trampoline each add to the liability load — sometimes materially.
• Claims history. One paid claim raises next year's premium the way it does on any policy.

Set against a single uncovered event, the premium is small. A $2,000-a-year US policy is roughly $167 a month — less than most hosts spend on consumables and linen. Weigh it the same way you'd weigh a maintenance reserve: it's not a cost, it's the price of not being wiped out by one bad Tuesday.

Three claims where AirCover pays nothing and a policy pays out

Abstract coverage tables don't land until you run real events through them. Here are three that happen to ordinary small hosts, and who pays.

Scenario one is the one that got me. There's no guest to blame, so AirCover is out by definition, and the homeowner policy that would normally pay for an electrical fire has voided on the business-use clause. Only a policy that knows it's insuring a rental pays. The building doesn't care whose fault the wiring was.

Scenario two shows the loss-of-income gap. Say a guest's unattended pan starts a fire — genuinely guest-caused, so AirCover reimburses the (depreciated) repair. But the unit is unrentable for six weeks. At $120 a night and 70% occupancy that's roughly $5,000 of bookings gone, and AirCover reimburses none of it. The business-interruption rider does.

Scenario three is the cross-platform trap. The exact same injury on an Airbnb stay would hit AirCover's $1M liability. On a Booking.com stay, AirCover doesn't apply, Booking.com offers no host liability cover, and a lawsuit lands entirely on you. Your own policy doesn't care which channel the guest came through — which is the whole reason a multi-platform host needs one.

How to buy it without overpaying

You don't need the most expensive policy on the market. You need the right five layers, honestly declared.

1. Declare the short-term use explicitly. To your insurer, and to your mortgage lender where the loan requires it. An undeclared claim is a denied claim.
2. Match liability to your exposure. $1M is the floor. Go to $2M if you have a pool, hot tub, or stairs guests use in the dark.
3. Add the loss-of-rental-income rider. For a full-time listing this is usually the highest-value line in the policy.
4. Keep AirCover as a backstop, not the plan. It's free and it does pay guest-caused damage. Let it be the first $50–$800 layer; let the policy be the catastrophe layer.
5. Keep your claim evidence tight. Dated check-in and check-out photos, a clean record of who stayed and when, and receipts for anything valuable. Documentation decides borderline claims on every scheme. If you're wrangling guest records and stay history across platforms by hand, that's exactly the paperwork a tool like RentTools keeps in one place — the same records you'll need the day you file.

One opinionated take

Most hosts treat AirCover as their insurance because it's free and Airbnb puts a big number next to it. That's the expensive mistake. AirCover is a nice backstop for guest-caused damage on Airbnb stays — and it is nothing else. The day your building burns from your own wiring, or a Booking.com guest breaks a wrist on your stairs, or a leak blocks your calendar for a season, the free number pays zero and your voided homeowner policy pays zero, and you find out you've been running a small commercial business fully uninsured. Price the real policy, declare the use, add the loss-of-income rider, and keep AirCover for what it's good at. The premium is the cheapest line on your P&L until the one year it's the only one that matters.
