If you’re planning to move home in Lincoln and already have a mortgage in place, you might be wondering if you can take your current mortgage deal with you.

This is known as “porting” your mortgage, and it’s something many lenders allow, especially if you’re mid-way through a fixed-rate period.

Porting a mortgage can help you avoid early repayment charges and keep hold of an interest rate you’re happy with, but it’s not always guaranteed. Here’s how it works and what to consider.

What Might Stop You from Porting

Even if your mortgage is technically portable, your lender will still carry out a new assessment based on your updated circumstances.

They’ll look at things like your income, outgoings, and credit history to decide whether the mortgage still fits.

If your situation has changed since you first took out the mortgage, perhaps you’ve changed jobs, taken on more financial commitments, or become self employed, the lender might decide not to approve the port.

Some mortgage products also come with restrictions that can make porting more difficult.

As a mortgage broker in Lincoln, we can review your current deal and explain whether it’s likely to be portable before you commit to anything.

Should you stick with the same lender?

Porting usually involves staying with the same lender, but that doesn’t always mean it’s the best route.

Your current lender will offer you their available products if a new borrowing assessment is approved, but those deals might not be as competitive as what’s available elsewhere.

It’s worth comparing the cost of porting your mortgage against the cost of switching to a new lender, even if that means paying early repayment charges.

In some cases, the long-term savings from a better rate can outweigh the initial cost of leaving your current deal.

We’ll help you weigh up the pros and cons so you can make a decision that suits your next step.

What if you’re borrowing more?

If you’re moving to a more expensive home in Lincoln and need to borrow more, your lender may agree to port your current mortgage and add a new product for the extra borrowing.

This is common, but it’s important to understand that the additional borrowing may be on a different interest rate and product term.

Lenders assess the extra borrowing separately, and approval will depend on your affordability and credit profile.

We’ll work with you to check whether your lender is open to this approach and what the impact might be on your monthly payments.

How do mortgage sub-accounts work?

When you port your mortgage and borrow more on a new deal, most lenders set up your mortgage in sub-accounts.

This means your original borrowing continues under the existing terms, while the new borrowing runs on a separate product.

Each sub-account may have its own fixed or variable rate and expiry date.

This can make things a bit more complex if you plan to remortgage later on, as you may need to align the deals or consider whether to combine them into a single mortgage.

We’ll explain how sub-accounts work in plain terms and help you avoid unexpected issues down the line.

Is porting still the most suitable option?

Porting can be a good way to keep your current rate and avoid fees, but it’s not always the most cost-effective move.

Depending on what’s available on the wider market, you may find that starting a new mortgage altogether gives you more flexibility or a better rate.

As a mortgage broker in Lincoln, our job is to explore both paths and show you the full picture, whether that means staying with your current lender or switching to a new one.

We’ll guide you through every step and help you make the move as smooth as possible.
