The home/building insurance for TICA is through SGAU. LL insurance is underwritten by Allianz.
Fixed term lease = 6/12 month etc lease. If the tenant goes onto a periodic (ie month to month) then GIO will not cover any rent default anymore.
I have moved mine across to TICA landlord insurance after GIO changed their policy to not cover rent default when the tenant is not on a fixed term lease.
No excess on rent default claims, up to 15 weeks rent cover plus the usual other things...
