Moving Home Mortgage Guide – Moving home with a mortgage can feel confusing because you may have multiple options. You might be able to port your current mortgage to your new property, apply for a new mortgage, borrow more, reduce your mortgage, or change lenders.
This moving home mortgage guide explains how the process works, what lenders usually check, what costs to prepare for, and how to find the right adviser for your move.
Connect Experts helps you find a mortgage adviser who can support your home move. We are a mortgage adviser directory and matching platform. We do not provide mortgage advice directly. Advice is provided by the adviser or firm you choose.
Your home may be repossessed if you do not keep up repayments on your mortgage or any loan secured on it.
Quick answer: What happens to your mortgage when you move home?
When you move home, your current mortgage does not automatically move with you. You normally have two main choices:
- Port your existing mortgage deal to your new property if your lender allows it and you still meet their criteria.
- Apply for a new mortgage with your current lender or a different lender.
Your best option depends on your current mortgage rate, early repayment charges, equity, income, credit profile, the new property value, and how much you need to borrow.
A moving home mortgage adviser can compare your options before you commit to a sale or purchase.
Moving home with a mortgage: your main options
Option 1: Port your current mortgage
Porting means transferring your existing mortgage deal to a new property. This may be useful if you are on a competitive fixed rate or if leaving your current deal would trigger early repayment charges.
Porting is not guaranteed. You still need to apply to the lender again. The lender will reassess your income, outgoings, credit history, affordability, and the property you want to buy.
Porting may work well if:
- Your current rate is lower than new rates available.
- Your lender accepts the new property.
- Your income and circumstances still meet the lender’s criteria.
- You do not need to borrow much more.
- The cost of leaving your current deal is high.
Porting may be less suitable if:
- Your lender will not approve the new borrowing amount.
- Your circumstances have changed.
- You can find a better overall deal elsewhere.
- Your new property does not meet your lender’s requirements.
- You need extra borrowing at a separate, less competitive rate.
Option 2: Apply for a new mortgage
A new mortgage may be better if your current deal is ending, you need to borrow more, your existing lender is not competitive, or your circumstances have changed.
A new mortgage could help you:
- Compare rates across a wider range of lenders.
- Change mortgage type or term.
- Borrow more for a larger property.
- Reduce borrowing if you are downsizing.
- Move to a lender better suited to your circumstances.
Before choosing a new mortgage, check whether you will pay early repayment charges, exit fees, valuation fees, arrangement fees, legal costs, or broker fees.
If your mortgage rate is ending soon, it may be worth comparing your moving and remortgaging options at the same time.
Porting vs new mortgage: Which option should you consider?
| Question | Porting may suit you if | A new mortgage may suit you if |
|---|---|---|
| Is your current rate competitive? | Yes, your current rate is worth keeping | No, other lenders may offer a better deal |
| Are there early repayment charges? | Yes, porting may help reduce or avoid them | No, switching may be easier |
| Do you need to borrow more? | Only a small top-up is needed | You need significant extra borrowing |
| Have your circumstances changed? | Your income, credit and commitments still fit | A different lender may assess you more favourably |
| Is your current lender flexible? | Yes, they accept the new property and loan size | No, another lender may be more suitable |
| Do you want wider choice? | You are comfortable staying with your lender | You want to compare more of the market |
A mortgage adviser can help compare the total cost, not just the interest rate. This should include fees, early repayment charges, monthly payments, term, flexibility and lender criteria.
How mortgage affordability works when moving home
When you move home, the lender will check whether the new mortgage is affordable. This applies whether you are porting your current deal or applying for a new mortgage.
Lenders usually consider:
- Your basic income.
- Bonuses, commission, overtime or benefits where accepted.
- Self-employed income, accounts or tax calculations.
- Credit commitments.
- Childcare costs.
- Household bills.
- Credit history.
- Deposit or equity.
- Mortgage term.
- The new property value.
- The type of mortgage you want.
If you are upsizing, your monthly payment may increase. You may also face higher council tax, insurance, energy, service, maintenance, or commuting costs.
If you are self-employed, have recently changed jobs, are on maternity or paternity leave, receive variable income, or have credit issues, adviser support can be especially helpful.
You can find a mortgage adviser near you and choose by location, language, gender and mortgage expertise.
How your equity affects your moving home mortgage
Equity is the difference between your current property value and the amount left on your mortgage.
For example:
- Current property value: £350,000
- Outstanding mortgage: £220,000
- Estimated equity: £130,000
When you sell your current home, your equity can usually be used as the deposit for your next property.
Equity can affect:
- How much deposit you have.
- Your loan-to-value.
- The mortgage rates available to you.
- Whether you can afford a more expensive home.
- Whether downsizing could reduce or clear your mortgage.
- Whether you need additional borrowing.
A higher deposit may give you access to more mortgage options, but lenders still need to check affordability and property criteria.
Moving to a more expensive home
If your next home costs more than your current property, you may need extra borrowing.
This could mean:
- Porting your existing mortgage and adding a top-up loan.
- Applying for a completely new mortgage.
- Using savings alongside your equity.
- Extending the mortgage term to manage monthly payments.
- Review your budget before making an offer.
Be careful with top-up borrowing. It may be offered at a different rate from your existing mortgage, which can make the overall cost harder to compare.
A moving home mortgage adviser can help you compare the combined cost of porting and topping up against the cost of a new mortgage.
Downsizing your home
If you are moving to a lower-value property, you may be able to reduce your mortgage or pay it off completely.
Downsizing may help if you want to:
- Lower monthly repayments.
- Release equity.
- Reduce household costs.
- Move closer to family.
- Prepare for retirement.
- Buy a property better suited to your current needs.
Check whether your current mortgage has early repayment charges or overpayment limits. If you repay a large part of the mortgage early, charges may apply.
What costs should you budget for when moving home?
Moving home can involve more than the deposit and mortgage payment. Build a realistic budget before you make an offer.
Common costs include:
| Cost | What to check |
| Estate agent fees | Usually paid when selling a property |
| Stamp Duty Land Tax | Depends on price, buyer status and property ownership |
| Mortgage arrangement fee | May be paid upfront or added to the mortgage |
| Valuation fee | Some lenders charge this separately |
| Survey fee | Depends on the type and depth of survey |
| Conveyancing fees | Legal work for sale and purchase |
| Search fees | Local authority and property-related searches |
| Removal costs | Varies by distance, volume and service |
| Early repayment charges | May apply if leaving your current mortgage deal early |
| Broker fee | Your adviser should explain any fee before you proceed |
| Insurance | Buildings insurance is usually needed from exchange |
Stamp Duty rules can change, so always check the latest government guidance or speak with your adviser before relying on figures.
How long does a moving home mortgage take?
The moving home mortgage process can vary depending on the lender, property chain, valuation, legal work and your documents.
A typical process may look like this:
| Stage | Typical timing |
| Speak with an adviser | Before viewing or making an offer |
| Review porting and new mortgage options | Early planning stage |
| Agreement in Principle | Often within a few days, depending on the case |
| Offer accepted | Once seller accepts your offer |
| Full mortgage application | After property details are confirmed |
| Valuation and underwriting | Depends on lender and property |
| Mortgage offer issued | Often several weeks from application, case dependent |
| Exchange and completion | Depends on chain, conveyancing and readiness |
You can help avoid delays by preparing documents early. These may include payslips, bank statements, ID, proof of deposit, mortgage statement, accounts if self-employed, and details of credit commitments.
Documents you may need for a moving home mortgage
Your adviser or lender may ask for:
- Proof of identity.
- Proof of address.
- Recent payslips.
- Recent bank statements.
- Latest P60.
- Proof of bonus, overtime or commission.
- SA302s and tax year overviews if self-employed.
- Company accounts if applicable.
- Current mortgage statement.
- Proof of deposit or equity.
- Details of loans, credit cards or childcare costs.
- Property details for the home you want to buy.
Having these ready can make the process smoother.
Should you speak to a mortgage adviser before putting your home on the market?
Yes, it is usually sensible to speak with a mortgage adviser before you list your property or make an offer on a new home.
This can help you understand:
- Whether you can port your current mortgage.
- Whether a new mortgage may be better.
- How much you can borrow.
- Whether early repayment charges apply.
- How much deposit can your equity give you?
- What your monthly payments may look like.
- Which lenders may fit your circumstances?
- What documents should you prepare?
This can help you search for properties with a clearer budget and avoid surprises later.
