Cash Flow Creation

my husband has been approved for a va loan. we are aware of the no down payment, most of the closing costs being paid etc. my question is about the paperwork from the bank that gave him his pre-approval. there is a section in there which states they have to see $2000 in your bank account. we have what we need to move in, pay the fees our realtor has already outlined for us, etc but we do not have two grand sitting in the bank. i can understand why the bank is asking this. i’m curious about if they are just trying to make sure they are going to get their money will it matter that he is contracted with the military for the next 10 years? in other words, there will be a steady cash flow for at least that long. does anyone know?
on our approval letter it states “items needed” and at the bottom of the list it says $2000 in the bank for reserves., more
