Off-season math: close the listing or stay open?

I closed my coastal one-bed for four months in 2022 because the November spreadsheet said the month lost $380. It did — on paper. What the spreadsheet didn't say is that $790 a month of those costs ran anyway from December through March, and that closing saved me about $210 in cleaning and consumables I never bought. The four months I skipped would have contributed roughly $880. I paid something like $670 for a quiet winter, and came back in April with my most recent review dated 12 November.

Closing for the low season feels like cost control. It almost never is. It's revenue control, and the monthly profit-and-loss statement is the exact document that will hide the difference from you.

The accounting mistake that closes profitable listings

Your monthly sheet spreads the mortgage, the insurance premium, the internet bill, the municipal licence and a depreciation allowance evenly across twelve months. Then it subtracts that total from January's revenue, prints a negative number, and you conclude that January loses money.

January does lose money. That has nothing to do with whether you should sell nights in January.

There are two separate questions, and hosts collapse them into one:

1. Is this property worth owning? Full cost, measured annually. Every line counts.
2. Should I sell a night in February at $70? Marginal cost only. Most lines don't count at all.

Closing the listing changes exactly one column of your sheet — the variable one. It leaves the mortgage, the premium, the router and the standing charges completely untouched. So the moment you close, you haven't cut costs. You've cut the only thing that was helping pay them.

The test for any line item is blunt: does this bill change if I take one more booking? If no, it is irrelevant to the close-or-stay-open decision, no matter how large it is.

What one low-season night actually costs you

Three kinds of cost survive that test, and they behave differently.

Turnover-triggered — paid once per booking, regardless of length.

• Cleaner: $45–70 for a one-bed, more if they travel to you. See what cleaners actually charge.
• Laundry: about $3.50 in-house, $8–14 at a commercial service — the full per-turnover breakdown.
• Consumables: $6–9 of coffee, paper, soap and the rest, per cost per stay.

Call it $66 per booking for a typical one-bed. This is the number that decides everything below.

Per-night — paid for each night the guest is actually in the unit.

• Heating and hot water above the frost-protection baseline: $3–8 depending on climate and how badly the place is insulated. The utility cost math has the per-night figures.
• Wear: mattress life, paint, towel life, the slow death of the kettle. Honest allowance is 4–6% of the nightly rate, roughly $4 on a $90 night.

Call it $9 per night.

Percentage — a slice of whatever you charge. Airbnb host-only fees run about 3% and split fee about 3% on your side. Booking.com takes 15–18%, before VAT on the commission in most of the EU.

And here is what is not a marginal cost, no matter how much it hurts to pay it: insurance, mortgage or rent, internet, utility standing charges, licence fees, depreciation, your dynamic-pricing subscription, and the maintenance reserve you fund monthly. Every one of those is identical whether the calendar is full or empty.

Break-even is a stay-length problem, not a price problem

Once the turnover costs $66 and each night costs $9, the break-even nightly rate falls straight out. Divide by one minus the commission and you get the rate below which a booking makes you poorer.

Read that column top to bottom. The break-even rate falls by a factor of four between a one-nighter and a week, and your nightly rate never moved. Length of stay, not price, is what makes a low-season night profitable.

Take a $60 January night, which is the kind of rate that makes hosts want to close:

• One night at $60 on Airbnb. Revenue $60. Costs $66 + $9 + $1.80 commission = $76.80. You pay $17 for the pleasure.
• Four nights at $60 on Airbnb. Revenue $240. Costs $66 + $36 + $7.20 = $109.20. Contribution +$131.
• One night at $60 on Booking.com. Revenue $60, commission $9. Contribution −$24.

Same rate, same guest profile, same month. The difference is entirely the $66 you spend the moment anyone walks through the door.

So the low-season lever is the minimum stay, not the close button. Push the minimum-night setting from 1 to 3 in your low months and most of the bookings that were losing you money simply stop arriving, without you giving up the ones that weren't.

Three markets, one low-season month each

The same arithmetic, applied to a one-bedroom in three different kinds of market. All figures are for a single month.

Nobody closes the city listing. Nobody should close the coastal one either — five months at $193 is $965, which is a mattress, a repaint and a new sofa.

The mountain column is the interesting one. Sixty dollars a month is close enough to zero that other factors decide it: you're on call all month for the price of a tank of fuel, and one 3-star review in a quiet month costs you more than the $60, because climbing a rating back takes twenty-odd stays and you're only doing four. That's a legitimate place to close — a decision about risk and attention, not about cost.

Notice what occupancy does in that table: nothing. It scales the size of the win, but it never flips the sign. As long as your achievable rate clears the break-even column, contribution is positive at 12% occupancy and at 58%. "My occupancy is too low to bother" is not an argument — it's a description of how big the number is, not which direction it points.

What closing actually saves, and the bills that don't stop

One line goes to zero. It was never really a cost — it was a deduction from revenue you also just stopped receiving.

The frost-protection row is the one that catches people. An occupied unit is heated as a side effect of somebody paying you to be there. A closed unit in a cold market still has to sit above freezing, and now nobody is paying for it. Depending on exposure that runs $30–90 a month: a mid-floor apartment with heated neighbours on both sides sits at the bottom of the range, a detached cabin well above the top. Closing can move your heating bill from "covered by guests" to "paid by you," which is the opposite of the direction you were aiming for.

Then check your policy's vacancy or unoccupancy clause before you commit to a dark quarter. Most property policies suspend or narrow cover after 30 or 60 consecutive days without occupation, and the claim that gets denied under that clause is almost always the same one: a pipe that froze and split in week ten, discovered in week twelve. Short-term rental policies vary a lot on this — some accept a documented weekly inspection as continued occupancy, some don't. It is a five-minute phone call and it is the difference between a $400 repair and a $14,000 one.

The cost of going dark on the platforms

There is no published penalty on either platform for having a blocked calendar, and hosts who tell you otherwise are guessing. What is real is quieter than a penalty and slower to notice.

Block dates. Never unlist. On Airbnb, blocking availability and snoozing the listing are completely different actions. A blocked calendar keeps a live, searchable listing that simply has no dates open; a snoozed or unlisted listing is removed from search entirely and has to re-earn its position when you switch it back on. If you plan to reopen in April, block dates.

On Booking.com, an extended closure is administratively expensive. With no open availability the property reads as closed, and coming back means reloading rates, restrictions and any seasonal rate plans you had running — hosts routinely reopen in spring with last year's plan still attached and don't notice for a fortnight. The status programmes, Genius and Preferred Partner, are assessed on rolling performance windows, so a five-month gap shows up in an assessment months after you stop thinking about it.

The real loss is review recency. Reopen in April after a dark winter and your most recent review is dated November. Both platforms weight recent activity, and every guest reading your page in April is reading a page whose newest signal is five months old. The inverse is the underrated part: a January review is cheap to earn, because you're one of the few listings taking bookings, and it's the review that will be sitting at the top of your page when the March booking window opens. Two winter reviews are worth more than two August ones for exactly that reason — the same logic that governs pricing a brand-new listing.

When closing is genuinely the right call

Four cases, and one of them beats the math outright.

A nights-per-year legal cap. This is the real one. If your city caps entire-home lets at 90 or 120 nights a year — London, Amsterdam, and a growing list of others — then a night is not a renewable resource. Selling a January night at $65 spends a cap-night you could have sold in August at $180. That's a $115 opportunity cost on a booking the contribution table says is profitable, and it inverts the whole decision. Under a cap, close the low season without doing any further arithmetic.

You need the building. Painting, refinishing floors, replacing a bathroom. But price the closure honestly: a full one-bed repaint is 3–4 days, a floor sand-and-seal is 5. That's ten blocked days, not a blocked quarter. Hosts routinely close four months to do a job that needed a fortnight, then describe the lost contribution as the cost of maintenance.

The unit isn't safe or reachable. Seasonal water shut-off, a road that closes, heating that can't hold the place at 20°C in February. Not a math problem.

Attention. Being on call all winter for $60 a month is a bad trade and you're allowed to say so. Just say it in those words — "I'm buying quiet for $60 a month" — instead of dressing it up as cost control.

And before you close, price the third option. A single three-month mid-term let over the winter has one turnover instead of twelve, no per-night marketing, and a rate that beats your low-season ADR on a monthly basis in most markets. The mid-term rental math usually looks better than both closing and grinding out 22% occupancy.

Whichever you pick, keep the calendars talking to each other. The double-booking that actually hurts is the one in a quiet month, because you stopped checking daily around week three — a January guest you half-forgot turning into a February clash you find out about from the guest. That's what RentTools does for free: every platform sees the others' bookings, including the ones you booked in a month you weren't paying attention.

One opinionated take

The close-or-stay-open argument is really an argument about which document you're reading. A monthly profit-and-loss statement is a report on the past; it was never designed to make forward decisions, and every time a host uses it as one it tells them to shut down the thing that was paying the bills. Run the contribution number instead and the answer is usually the same: almost nobody who closes for the season is saving money. They're buying quiet — about $200 a month for a coastal one-bed — and that's a perfectly reasonable thing to buy, as long as you say out loud that's what you're doing.
