The wider assessment
Treat the move as a new lending decision
The existing lender reassesses the applicants and new property. If you need more borrowing, the extra amount may sit on another product with a different rate and end date. Sale and purchase dates can also affect whether any early repayment charge is paid and later refunded.
Portability does not guarantee approval or preserve every term. Check application deadlines, early repayment charges and what happens if the sale and purchase do not complete together.
