Yedlin signed a four-year contract with Tottenham on Wednesday but it was immediately announced the United States right-back will spend the rest of the MLS season with Seattle.
Hanauer reckons the deal suits all parties, as the Sounders aim for their maiden MLS title and Yedlin continues to develop before moving to the London club.
"This transaction provides, first, a great opportunity for us to win a championship in 2014 with DeAndre remaining with the team," Hanauer told the official website of the MLS.
"Second, it provides us with allocation money that is paramount to maintaining a competitive squad going forward."
Yedlin played 33 games for Seattle last season and has made 14 appearances so far in 2014 as the Sounders lead the American top tier's Western Conference.
Since the Sounders joined the MLS in 2009 they have won the US Open Cup three times, but have failed to win the league.
