No. Pre-qualification simply means that a lender has reviewed the preliminary information you have provided, including your monthly or annual income. Based on this preliminary information, the lender will pre-qualify you for a certain amount.  A credit check may not have been run and the lender is not yet in receipt of written documentation supporting your claims.  You will only qualify and be approved for the loan, when you actually apply and submit all necessary documentation and a credit check proves you are worthy of being approved for the loan.
