Right, but if the point is to increase liquidity, the low hanging fruit is mortgage backed purchases. Homeowners will often take a smaller offer price in favor of cash because the closing process is easier/more certain. So Zillow might be trying to arbitrage that price difference between cash and mortgage purchases. And if they can find a way to scoop up part of the loan origination fees and the broker fees in the process, than I guess there could be some compelling revenues there.
