TL;DR: Month-to-month bookings on Radius have a structured extension and Notice to Vacate (NTV) workflow built into the platform — a 120-day calendar hold, tiered Host response deadlines, and an automatic NTV that records itself if no one acts. You manage the end date in one place: the Confirm end date step. Keep the current checkout date to end the stay as scheduled, or pick a later date to request an extension. For fixed bookings, there's no extension button — message the Host directly to change dates.

🚨 Month-to-month: Most of this article covers the month-to-month extension workflow. Insurance housing is the most common use case — adjusters approve housing in increments, so these stays almost always extend. If your stay is a fixed booking, skip to the short section on changing fixed-booking dates below.

Radius handles stay changes differently depending on the booking type, which the booker chooses at checkout on listings that offer month-to-month:

The month-to-month workflow exists because these stays — insurance placements especially — almost always extend. Adjusters approve housing in increments, so the original booking rarely covers the full stay. Radius protects the Host's calendar with a 120-day trailing hold after the scheduled checkout — giving the stay room to extend without the Host losing those dates to a competing booking. Every month-to-month booking also carries a Notice to Vacate (NTV) period — a required notice window before the stay ends. If no one acts on it, the system records the NTV automatically.

🏠 Host: Month-to-month eligibility is on by default for every listing — you don't have to turn anything on to accept these bookings. You can turn it off anytime in your listing configuration; bookings already confirmed keep their original terms.

For fixed-term bookings, there's no in-platform extension button. To change your dates:

💡 Tip: The rest of this article covers the month-to-month extension workflow. If your stay is a fixed booking, the section above is all you need.

When a month-to-month booking is confirmed, Radius automatically holds the Host's calendar for 120 days after the scheduled checkout date. This trailing hold protects the stay so extensions can be approved without a competing booking already sitting on those dates.

🏠 Host: You'll see the held dates on your calendar. The hold moves forward automatically whenever you approve an extension — it always sits 120 days past the current checkout date.

👥 Booker: The hold is there to protect your stay — you don't need to do anything about it. Just submit extension requests before the NTV deadline when you need more time.

When more time is needed — for an insurance placement, that's typically when the adjuster approves another increment — the Booker requests it from the booking. Open the booking, choose Confirm end date, pick a date later than the current checkout, and submit. That sends an extension request to the Host. The Host is notified immediately. Only one extension request can be pending at a time — to change the dates on a pending request, withdraw it first and submit a new one.

👥 Booker: Submit your request before the NTV deadline (see Step 5). Extension nights bill at the booking's original nightly rate — no price change even if the Host has updated their listing rates since you booked.

Every extension needs the Host's approval — there's no auto-approval. The Host has a limited window to approve or decline, and how long depends on how soon the current stay is set to end:

If the Host doesn't respond before the deadline, the request expires — treated the same as a decline. Both the Booker and the Host are notified either way.

🏠 Host: You'll see the countdown on the booking. Approve or decline based on your availability — if you don't respond in time, the request expires and the Booker is notified that it wasn't approved.

When the Host approves, the booking's end date moves forward and the 120-day hold resets from the new checkout date — so the stay stays protected for the next extension. The extended nights are billed on your normal payment schedule at the original nightly rate, and the flat 8% booking fee applies to those nights just as it did to the original booking.

💡 Tip: Extensions can happen multiple times on the same booking — one at a time, in sequence. Each approval moves the end date and the calendar hold forward together.

Every month-to-month booking has an NTV period — a required notice window before the stay ends. It's set when the booking is created and never changes, even if the stay is later extended.

💡 Tip: The NTV period is locked to the initial booking length, not the current one. A 45-day booking extended to 90 days keeps its 14-day NTV — it doesn't jump to 30.

Either the Booker or the Host can give Notice to Vacate. Giving NTV confirms the stay will end on its scheduled checkout date and that no further extensions are coming. For the Booker, that's the Confirm end date step — keep the current checkout date selected and submit. NTV doesn't move the checkout earlier: dates before the current checkout are greyed out, because ending a stay early is a separate change to the reservation, not an NTV. When NTV is given, the 120-day hold is released and the Host's calendar opens for new bookings after the checkout date.

👥 Booker: You can reverse your own NTV if the adjuster later approves more time — as long as no other booking has been confirmed on the dates that would need to be re-held. If there's a conflict, the reversal is blocked and you'll see which dates are unavailable; book a different property for the remaining period.

🏠 Host: You can give NTV for the current checkout date only — it confirms the stay ends as scheduled and releases your calendar hold (you can't shorten the stay or extend it). You'll confirm a warning first, since it affects the stay. Host-given NTV can't be reversed by you — contact Radius Support if you need to undo it.

If neither the Booker nor the Host gives NTV, and no extension request is pending, the system steps in. A daily task checks every month-to-month booking, and once the NTV deadline passes (the NTV period before checkout) with no action, it records an NTV on the booking automatically — a real NTV event, not just a reminder. The stay still ends on its already-scheduled checkout date.

⚠️ NTV: Before the automatic NTV records, both the Booker and the Host get reminders — the day before and the day of the deadline. Don't ignore them: once the NTV is recorded, the 120-day hold releases and the Host's dates open to other bookings. If you need more time, submit an extension request before the deadline.

The request expires when the response window closes (48h, 24h, or 12h depending on how soon the stay ends), which counts as a decline. Both parties are notified. The Booker can submit a new request with different dates, or book a different property for the extended period.

If a Booker gave NTV but later needs more time, the Booker can reverse it — as long as no other booking has been confirmed on the dates that would need to be re-held. If there's a conflict, the reversal is blocked and the Booker sees which dates are unavailable.

Ending a stay early isn't a Notice to Vacate — the Confirm end date step greys out dates before the current checkout. An earlier move-out is a separate change to the reservation. Message the Host through the booking thread or open a ticket with Radius Support, and the Booker stays responsible for the stay through the scheduled checkout date.

Once NTV has been given (or the auto-sweep has fired), the 120-day hold is released. A Booker can still reverse the NTV or submit a new request, but the Host's dates may already be taken by another booking. Availability is first-come, first-served at that point.

The Booker can place a new booking at a different property for the extension period using the standard search flow. See How the "Book for Others" flow works.

How is the NTV period calculated?

It's based on the initial booking length: 14 days for bookings of 60 days or shorter, 30 days for bookings longer than 60 days. It's locked when the booking is created and never recalculates, even if the booking is later extended to a longer duration.

Can I set an end date earlier than the current checkout?

Not through extensions or Notice to Vacate — the Confirm end date step only confirms the current checkout date or moves it later, and earlier dates are greyed out. Ending a stay early is a separate change to the reservation: message the Host or contact Radius Support. Month-to-month bookings are treated lease-style, so the Booker remains responsible through the scheduled checkout date.

Can a Host reverse an NTV?

No. Only the Booker can reverse an NTV, and only if no conflicting booking has been confirmed on the dates that would need to be re-held. If a Host needs to undo an NTV, they should contact Radius Support.

Is the extension billed at the same rate as the original booking?

Yes. Extension nights are always billed at the booking's original nightly rate, regardless of any listing price changes the Host made after the booking was confirmed. The flat 8% booking fee applies to the extension nights too.

What does the auto-sweep actually do?

It's a daily system task that records an NTV on your booking once the deadline passes with no action — the same as if someone had given NTV manually. It only runs when there's no active NTV and no pending extension request. Both the Booker and the Host get reminders the day before and the day of the deadline before it records.
