Multifamily buildings and units
A building holds units; units inherit the building's owner links and fee rates automatically, and a unit only needs its own owner link when its ownership differs — the override wins wholesale. Each unit rents, lists on Airbnb and publishes to your booking site on its own; the building itself is a container, not a listing.
Multifamily in Nexxus is a building with units under it. Tenancies, ledgers, listings and occupancy live at the unit level; ownership usually lives at the building level.
Owner inheritance
Owner links set on the building flow down to every unit automatically — assign the owner once, and each unit's rent attributes to them at the building's fee rate. Unit pages show these as inherited links, labeled with where they came from and the effective percentage.
When a unit is different (condo-style)
If one unit has different ownership — a condo sold off, a unit with its own investor — give that unit its own owner link with Override for this unit on the unit's Settings tab. A unit-level link overrides the inherited set entirely (it doesn't blend): the unit uses its own owners and rates, and the building's links continue to cover the other units.
What this means for money
Payout runs, statements, and 1099s all resolve each unit's owner through the same rule — unit link if present, otherwise the building's — so the books always match what the unit pages display. The management fee resolves through the usual cascade on top of whichever link applies.
Leasing units
Each unit rents independently: its own tenancies, its own ledger, its own spot on the calendar. The double-booking guard applies per unit — two leases can't overlap on one unit, but different units of the same building rent freely in parallel.
Listing units on Airbnb and your booking site
The building is a container, never a listing. The Channels page shows only rentable units ("Parent buildings aren't shown"), so you connect each unit to its own Airbnb listing, with its own prices and calendar. Units publish to your booking site one by one too; on the site's map, units sharing a building's address are spread slightly apart so every pin stays clickable.
Setting one up
Create the building, add its units with Add unit on the Units tab, then assign the building's owner on the Settings tab. A building's page carries just Overview, Units and Settings — bookings, listings and ledgers live on each unit. Only visit a unit's owner settings when that unit genuinely differs.
Marking a building "No longer managed" applies to all of its units — see deleting properties and bookings.

Owners, ownership percentages, and owner links
An owner is linked to a property with an ownership %, a management fee %, a management period and an optional monthly deduction. Ownership in force can't exceed 100%, and payouts, statements and 1099s all split by each owner's share.
Management fees and owner deductions: where the percentages come from
The fee rate cascades: booking override → the owner's rate on the property link → the company Default management fee %. Units inherit their building's owner links. Standing monthly deductions post once per scheduled run, and one-off owner expenses go on a draft run as Expense deduction lines.
Can two leases overlap on one unit? The double-booking guard
No — a unit holds one direct tenancy at a time, enforced everywhere a booking is created or moved. Back-to-back same-day turnover is fine; room-by-room properties and Airbnb stays are exempt. Every stay and block also closes those nights on Airbnb and your booking site.
Connecting Airbnb: live two-way sync for your listings
Yes — Nexxus connects to Airbnb directly. On the Channels page you sign in with Airbnb (no password shared), pick which Airbnb listing each unit is, and activate: upcoming reservations come in, then bookings, changes, cancellations, requests and guest messages flow in while availability, rates, fees and booking settings push out. Listing text, photos and reviews stay on Airbnb.
Deleting properties and bookings — and why some deletes are blocked
Deletes are allowed only when no real money or recorded history is attached. For a property you've stopped managing, use "No longer managed" instead — history stays, capacity ends. Disconnect an Airbnb-connected unit first, and cancel Airbnb reservations on Airbnb, not by deleting them.
