I got fully funded with Prosper.com, they emailed me and said that it was under final review whats that??

Answer 1

Usually if something is fully funded, it has already gone through review. Interesting.
But anyway, final review is what is called as "Underwritting".
Its a person who goes through the documents, and your financials with scrutiny to make sure nothing was over-looked. Its basically a way to make sure you do in fact qualify for a loan.
