$4m is roughly the figure I've been hearing for both. Not their prefered figure but thats the number they'd probably accept.
In paying that you'd also have to cover the losses that both the Dome and the 36ers would make annually.
From what I'm hearing the Dome loses between $250k & $500k a year currently, the 36ers between $1m - 1.5m.
You'd also have to supply the $1m bank guarantee.
And all NewNBL clubs are being forced to contribute to the costs of running the competition. As new owner of the 36ers you'd have to put up approx. $85,000 to set up the NewNBL office & pay for a GM (without having any input as to who that GM is or anyone else in the NewNBL office for that matter) and $50,000 for a central marketing campaign (which based on BA's latest attempt at a video I would consider $50k for zero return).
Then during the season you'd be expected to pay into the travel fund, pay for NewNBL League events such as the MVP Dinner (which didn't happen this year because the clubs wouldn't pay for it and BA certainly weren't going to) as well as all the other bits and pieces the clubs are forced to pay for themselves.
In return the NewNBL/BA would give you a spot in a compeititon which may have 9 teams, and may have anywhere from 11 - 16 home games and may have a TV deal with Fox which may or may not include live games against the gate. The NewNBL would take control of your brand, take control your website, take control of merchandising (but you'd get some return, what that is no one knows) and a percentage of gate takings from all Finals games.
Big risk for any businessman to buy into, full credit to those willing to lose millions of their hard earned $$s just to be involved in a second tier sporting league.
