As noted above, the relocation fee imposed by the league has to be fit into the offer, along with other related costs. So Sacramento bidders can actually underbid Hansen and pay more directly to the Maloofs.
Johnson had a buyer for a team back two years ago when the Maloofs were trying to both blackmail the city into buying them a new arena while also trying to sell the team to anyone who wanted it and also keep it while moving. That was the reason the league didn't immediately approve the Anaheim move. I'm sure they have even more offers now that the city has agreed to throw away taxpayer money on an arena.
EDIT: From Jao's link:
This has played out over the last 24 hours as multiple buyer groups have stepped up in Sacramento to buy the Kings, including a group that is connected to Ron Burkle.
Anybody moving the team will have to account for at least $100 million in unpaid loans to Sacramento (~$75 million) and relocation fees (~$30 million), and this is a very low estimate. That number increases as you account for moving costs, and the fact that the relocation fee could be more than $30 million. We’re reporting that this number could go as high as $300 million if the league really wants to flex its muscles in getting what it wants.
In a moment of levity at that charity event, attendee LeBron James was asked by Johnson if he could buy the Kings and keep them in Sacramento and he responded with, “get me my check book.”
LeBron isn’t going to have to reach far because Sacramento buyers have been making themselves known over the past 24 hours. Mark Mastrov, former CEO of 24 Hour Fitness and San Francisco investment firm JMA Ventures have thrown their hats in the ring.
Burkle was the guy Johnson had an offer from back in 2011.
