Ive been pre qualified for a 100k house?

i found a house i like and had the ispection done and have the contract all signed. also have all the documents the bank has asked for. this is an fha loan as im a first time buyer. i am getting help with the down payment of 3500.00. but my problem is i only have 4000.00 in my bank acct after the lawer, inspection and mortg app. fha rules say that no reserves are required so is the bank going to give me a hard time with having low cash amount in the bank? thanks
