There's a possibility it will be. Sometimes lenders will keep your loan and you can pay them directly each month, but it's not uncommon for them to sell the servicing rights to a loan after you close. This frees up credit lines and enables them to lend money to other borrowers.
You'll be notified if we plan to sell your loan. When you receive your Loan Estimate, check the third page under the Other Considerations section. You'll see check boxes indicating whether we intend to service your loan at Ally or transfer the servicing once your loan is funded.
