Can You Port Your Mortgage When Downsizing?
When people think about moving home, they often assume they have to repay their existing mortgage and arrange a completely new one. Whilst that may sometimes be the right approach, many mortgages are portable, meaning the existing mortgage product may be transferred to a new property, subject to the lender approving the application.
As a mortgage adviser helping clients across Romford, Brentwood, Chelmsford and the wider Essex area, my role is always to look at the whole picture before recommending the most suitable solution.
Recently I helped a client who was downsizing and wanted to make the most of the equity built up in their home without giving up mortgage products that still represented excellent value.
The client was selling their existing property for over £500,000 and purchasing a new home for approximately £380,000.
They already had two Halifax mortgage accounts with a combined balance of around £295,000. One of those mortgage products was fixed at just 2.60% for a further year, whilst the second remained fixed until late 2026.
Replacing both mortgages with today’s rates would have meant giving up a product that was still extremely competitive.
Rather than arranging an entirely new mortgage, we explored whether porting the existing Halifax mortgage would provide the better solution.
Looking Beyond The Mortgage
Many people assume downsizing simply means using all of the proceeds from the sale to reduce the mortgage balance. However, every client’s objectives are different.
In this case, the client wanted to retain a healthy level of savings whilst also setting aside funds to carry out substantial refurbishment works once they moved into the new property.
By carefully structuring the transaction, the existing Halifax mortgage products could be ported to the new home, allowing the client to retain their favourable interest rates whilst still releasing a significant amount of equity from the sale.
The recommendation wasn’t simply about obtaining the cheapest mortgage available today.
It was about preserving mortgage products that were already excellent, maintaining financial flexibility and ensuring the client’s wider objectives were achieved.
Why Porting Was The Right Solution
Mortgage porting isn’t suitable for every client.
Although many mortgage products are described as portable, lenders still assess the new application in much the same way as a brand-new mortgage. Affordability, income, credit history and the suitability of the new property all need to satisfy the lender’s current lending criteria.
In this case, the application met Halifax’s requirements and porting proved to be the most appropriate recommendation.
It allowed the client to:
- Retain an existing mortgage fixed at 2.60%.
- Keep their second fixed-rate product.
- Release significant equity from the sale.
- Retain funds for savings and refurbishment.
- Avoid replacing competitive mortgage products unnecessarily.
Importantly, porting wasn’t recommended automatically. We first considered the alternatives before concluding that retaining the existing mortgage products offered the greatest long-term benefit.
That is exactly how professional mortgage advice should work.

Understanding How Mortgage Porting Works
One of the biggest misconceptions surrounding mortgage porting is that the lender simply transfers your mortgage from one property to another.
In reality, the process is slightly more involved.
Your existing mortgage is redeemed when your current property is sold and, simultaneously, the lender recreates the borrowing against your new property using the existing mortgage product.
Although you’re keeping the product, the lender will usually assess your circumstances again.
This means affordability, income, credit history and the property itself will normally be reviewed before approval is given.
Where clients are upsizing, additional borrowing can often be arranged alongside the ported mortgage.
Where clients are downsizing, as in this case, the focus is often on retaining valuable mortgage products whilst releasing equity from the sale.
Another important consideration is that different mortgage accounts can often have different product expiry dates.
Here, one Halifax mortgage remains fixed, whilst the other will be reviewed sooner through a Halifax Product Transfer when the current fixed period comes to an end.
Structuring the borrowing in this way allows each mortgage account to be managed individually, rather than unnecessarily replacing everything at once.
Mortgage porting isn’t available in every circumstance, which is why professional advice is so important before committing to a move.
The Outcome
The final recommendation achieved exactly what the client wanted.
- Existing Halifax mortgage products were retained.
- A valuable 2.60% fixed rate was preserved.
- Significant equity was released.
- Funds were retained for savings and refurbishment.
- The move to a lower-value property was completed successfully.
- A future Product Transfer will be considered when the second fixed rate expires.
Every move is different. Sometimes replacing your mortgage is the right answer. Sometimes porting an existing mortgage provides significantly better value.
That’s why I always assess every available option before making a recommendation.
