What to Check After the Last Mortgage Trial Payment
After a mortgage trial payment plan, confirm the final agreement, effective date and next payment before updating your budget.
After making the last scheduled mortgage trial payment, verify what happens next. Keep the trial-payment confirmation, the final modification agreement if available, and the written effective date together. Confirm the amount and due date for the period between the last trial payment and the first payment under the modification.
Check which milestones are complete
Ask whether the servicer received and applied the last trial payment, whether it still needs any signatures, and when it expects to confirm the new terms. If a document needs to be returned, note the deadline and save proof of delivery through the servicer's accepted channel.
Under the Fannie Mae Flex Modification guide, completing the trial plan is one of several conditions for the modification to become effective. The guide also calls for the borrower to sign and return the agreement and for the applicable party to execute and date it. Ask which program governs your loan and follow the terms of your own written agreement.
Compare the first bill with the final agreement
Suppose a trial payment was $1,320 and the final documents show $1,375 starting on a stated date. The $55 difference matters for your budget. If the next bill still shows $1,320 or shows a different date, ask what amount is due and whether an escrow amount is included. Request a written explanation of the difference.
Use the Payment Calendar to record the confirmed due date and amounts. Keep the last trial receipt and first bill so you can check how the transition was posted.
