Can I port my mortgage when buying a less expensive home?

Why this becomes a closing problem

A homeowner sells to lower monthly costs and expects the port to eliminate the penalty. The new mortgage is much smaller, so part of the old balance must be discharged. That unexpected penalty uses money set aside for moving or retirement.

A practical example

If $500,000 remains and the new home needs only a $320,000 mortgage, the lender must decide what happens to the other $180,000. The annual prepayment privilege may reduce the amount exposed to a penalty, but the privilege, timing and permitted sequence come from the contract.

How the lending routes may differ

• A lender: first test the existing lender’s downsizing and partial-port calculation, then compare a full payout and new mortgage.
• Alternative/B lender: useful only if the new qualification or property falls outside A policy; higher pricing must be compared with the old penalty.
• MIC or private lender: rarely the first choice for a straightforward downsizing move, but may bridge a temporary title, sale or income problem with a clear exit.

Policy boundary: Porting, bridge periods, qualification, fees and property acceptance are lender and contract decisions. A regulator’s consumer information does not require every lender to approve the same structure.

Questions to ask before committing

• What is the minimum balance I must port?
• Is the unused portion subject to a penalty?
• Can I make my annual lump-sum prepayment before payout?
• Will using a privilege now reduce another privilege after the move?

Rajiv’s practical view

Get a dated payout statement and a separate written partial-port illustration. The decision should be based on net dollars after the sale, not only the new monthly payment.

Before making a firm offer or changing closing dates, confirm the full structure in writing. A pre-approval or verbal discussion is not the same as final approval of the borrower, property, sale, bridge amount and lawyer instructions.
