Presidential residence

Living in the White House limits the President's actions. He can't redecorate the way he wants, because it's America's house, it's a national museum. He can't even raise funds for his reelection because he's on public property. There's a way out of that. Build a family house on the White House lawn. Then rent the home to the next president. The house would then be his private residence

PS For presidential candidates that are in prison, we could build a small federal prison in the basement. Then the president could serve the time of their sentence in the basement of their presidential residence
