Assuming he liquidated the bank to 100M GP, he could sell that by itself for $80 assuming $.80/M - even if selling at a fire sale rate of $.70 he'd net $70 and have the account left to sell.
With his stats and quests completed [main draw being DS2], the account all by itself should easily sell for at least as much as the gold - and that's taking into account the newcomer status on Sythe. This account is Vorkath ready, meaning someone can jump on and start making that money back straight away.
