Yes, airbnb can hold your first payout for max. 30 days after the date the firsts reservation was confirmed.

The estimeeted payout date can be found in Transaction history ("future transactions")
If a security deposit is set (in section "pricing", see option "standard fees and charges" ), it is not charged to the guests, just sits in place when a claim is made (Allthough airbnb recently introduced extra rules:

Please note you accept bookings longer then 27 nights, but have not set a monthly discount. Then the listing will not show up for guests searching for "long term stay".
You have set "flexible" as a cancellation policy, which is very "guest friendly", but leaves you out of pocket when people cancel last minute.If you choose moderate, you protect yourself more (and there is allways the ability to manual refund a guest, if you feel so). But just IMHO.
