Marmion Short-Term Rental (Airbnb) Market
Estimated revenue assumes year-round availability. Non-hosted short-stays are night-capped in some councils (e.g. 60 nights across most of Byron Shire, 180 in Ballina, Muswellbrook and parts of Greater Sydney) and levied in Victoria — the legal cap can cut achievable income well below this figure. Run STR Check for the rules on a specific address.

BULL CASE
