I would love it if Prosper could TEST income verification.
Just pick a few listings and before they're allowed to go live, force the borrower to prove income. When income is proven, Prosper can put a silver star or something to make the listing look "special" to entice lenders to throw money at it.
Then when the note is created, we can control the loan against similar 3.0 loans where income was NOT verified and determine what the savings is and how much more Prosper lenders are willing to fund if the borrower had independently verified income.
All you have to do is have a Prosper borrower do is fill out a 4506-T form online, most of it already filled out by Prosper, then sign the form and fax it back with the barcoded coversheet to Prosper, and then it is filed with the IRS. When the 2-page computer readout comes back from the IRS, someone can just input the key figures (AGI for tax years 2009, 2008). Whatever the borrower stated as income is suppressed and only the figures that show on the 4506-T is displayed to lenders.
This process is EASY TO AUTOMATE using OCR SOFTWARE so Prosper humans don't need to be deeply involved.
Of course, Larsen knows he can do this but he doesn't give a shit or he would have already done it. They already have fax-autodetect systems running at Prosper because they use it for verifying ID on the FEW cases that they actually use it.
