Make sure to shop around to find the best price and test drive each car you’re interested in. Of course, now that you know your loan amount, don’t entertain any cars above your budget.
Your next step is to negotiate with the dealer. When you negotiate a purchase price, you can mention that you have loan preapproval, but don’t tell them how much it’s for. If you tip your hand, salespeople will try everything in their power to get you to spend the full amount.
Instead, use the preapproval letter as a bargaining tool to get the best price possible. Remember that you don’t have to spend the full amount for which you’re approved. You’ll owe less in the long run.
