Mortgage advice when you need to borrow more to move
Moving home isn’t just about finding a new property.
You also need to understand how much you can borrow, whether your current mortgage affects your plans and which lender will fit your next move.
You might want to know:
- Can I increase my mortgage when I move?
- How much more could I borrow?
- Will my current lender let me borrow more?
- Should I port my mortgage or apply to a new lender?
- Will my income support the property I want to buy?
- How much deposit will I have after selling my current home?
- Will early repayment charges affect my options?
- What happens if my circumstances have changed since my last mortgage?
These are exactly the questions a mortgage broker can help you work through.
The aim is to help you understand what is realistic before you offer on a property or make decisions about your sale.
Borrowing more when moving home at a glance
If you are moving home and need a larger mortgage, the right route will depend on your income, deposit, current mortgage, property value, sale proceeds, lender criteria and whether early repayment charges apply.
You may be able to borrow more by taking a new mortgage with another lender, porting your current mortgage and adding extra borrowing, or asking your current lender for additional borrowing.
A mortgage adviser can help you compare these options before you offer on a property, so you understand what may be realistic and what the overall cost could look like.
Key points to know:
- Your current lender may not always offer the best route
- Different lenders can assess affordability in different ways
- Porting and borrowing more can create separate mortgage parts
- Early repayment charges may affect your options
- Your sale proceeds and deposit can change what is possible
- Getting advice early can help you avoid viewing outside your budget
Why use a broker when borrowing more to move?
When you need to borrow more, the lender choice can make a significant difference.
Different lenders will assess your income, commitments, deposit and affordability in various ways. Your current lender may not offer the ideal route for you and the lowest interest rate may not be the most suitable option if the lender won’t lend what you need.
A mortgage broker can help you:
- Understand what you can borrow
- Compare your current lender with other options
- Check whether porting your mortgage is suitable
- Review whether early repayment charges apply
- Understand how your deposit and sale proceeds affect the move
- Check how different lenders assess affordability
- Avoid lenders that don’t suit your circumstances
- Compare the overall cost of borrowing more
- Prepare the documents you need for your application
- Manage the process from enquiry through to completion
This can save time, reduce stress and help you avoid making plans based on assumptions.
A MORTGAGE IS A LOAN SECURED AGAINST YOUR HOME. YOUR HOME MAY BE REPOSSESSED IF YOU DO NOT KEEP UP REPAYMENTS ON YOUR MORTGAGE OR ANY OTHER DEBT SECURED ON IT.
There may be a fee for mortgage advice. The actual amount you pay will depend upon your circumstances. The fee is up to 1% but a typical fee is 0.3% of the amount borrowed.
Ways to borrow more when moving home
Taking a larger mortgage with a new lender
One option may be to repay your existing mortgage when you sell and take a new, larger mortgage with another lender.
This could be suitable if another lender can offer a better fit for your income, borrowing needs, property type or longer term plans.
However, you may need to consider any early repayment charge on your current mortgage, as well as the costs of arranging a new mortgage.
We can help you compare the overall picture, not just the headline interest rate.
Borrowing more with your current lender
In some situations, your current lender can offer the extra borrowing you need.
This may feel convenient, but it’s still important to check whether this is the option for you.
Your current lender may not offer the level of borrowing you need, the most suitable rate, or the criteria for your circumstances.
A broker can help you compare your current lender with other lenders before you decide.
Porting your current mortgage and borrowing more
If your current mortgage is portable, you can look to take your existing deal with you when you move.
If you need to borrow more, the extra borrowing may be arranged separately by your current lender. This could mean part of your mortgage stays on your existing rate, while the extra borrowing sits on a new rate.
This can be useful, but it can also become more complicated.
You may need to think about:
- Whether your current lender will approve the move
- Whether you still meet their affordability rules
- What rate applies to the extra borrowing
- Whether the mortgage will have different parts
- Whether product end dates will be different
- Whether porting is still the best overall option
We can help you compare porting against a new mortgage so you can make a clearer decision.
Ways to borrow more when moving home
Borrowing more with complex income
Borrowing more can be more difficult if your income doesn’t fit a standard payslip.
This may apply if you’re:
- Self employed
- A company director
- A contractor
- Paid through CIS
- A freelancer
- Receiving bonuses or commission
- Working overtime
- Receiving allowances
- Recently promoted
- Recently changed role
- Earning from more than one source
Lenders will vary on how they treat this income. Some may use more of it than others.
Your Mortgage Expert can help you understand how your income is assessed and which lenders will be suitable for your move.
Why get advice before viewing or offering on a property?
If you need to borrow more, it is worth getting advice before you get too far into the moving process.
This can help you:
- Understand your realistic budget
- Avoid viewing homes outside your borrowing range
- Know whether your current mortgage limits your options
- Check whether early repayment charges matter
- Prepare documents before you apply
- Feel more confident when making an offer
- Reduce delays once your sale and purchase are underway
- Avoid disappointment later in the process
Moving home can be stressful. Getting clear mortgage advice early can make the process feel much more manageable.
