The message I received from Quicken Loans was that we will not give you any information on loans unless you give us all your personal information. No, we will not tell you how VA loans work, how a second mortgage might be leveraged, down payments for top tier credit scores, etc.
I highly recommend going with a local lender (e.g. Credit union) as they have no incentive to provide good customer service due to their size and control of the market.
