For people who might have a similar need in the future. Our solution was to use code

{{if \IPS\Member::loggedIn()->member_id && !\IPS\Member::loggedIn()->inGroup([11])}}
    {{\IPS\Output::i()->redirect( \IPS\Http\Url::internal( 'app=forums&module=forums&controller=index' ) );}}
{{else}}
    Sample text
{{endif}}

Which in essence shows one home page for logged in account and other custom home page to guests and other member groups.

Both guest version and for logged in accounts home page can be edited thorugh invision community page editor.
