Barnes is one of those rare parts of London that manages to feel distinctly separate from the city around it.
Set beside the Thames, with Barnes Common, the village pond, independent shops and restaurants all close by, SW13 has long appealed to buyers looking for more space and a quieter pace of life without leaving London behind.
The property market reflects that appeal. Period houses, larger family homes, riverside properties and characterful flats mean buyers can be dealing with substantial property values, and, in many cases, equally substantial mortgage requirements.
That can make arranging the finance an important part of the buying process.
At Oportfolio, we’re based nearby in Putney and regularly advise clients buying, moving and remortgaging across Barnes and the wider South West London property market.
Whether you’re planning a move to SW13 or already own a property here, this guide looks at some of the mortgage considerations worth understanding.
Why Buy a Property in Barnes?
Barnes offers something quite different from many other parts of London.
The area around Barnes Village and Barnes Pond has an almost village-like character, while Barnes Common and the Thames provide an unusual amount of green and open space for somewhere so close to central London.
For families, the area’s schools are another major attraction, with well-known independent schools including St Paul’s and The Harrodian alongside a number of local state schools.
Transport links include Barnes and Barnes Bridge railway stations, providing services towards central London, while nearby Putney, Hammersmith and Richmond offer further connections.
The housing stock is equally varied.
Depending on where you look in SW13, you might encounter Victorian and Edwardian houses, larger detached and semi-detached family homes, mansion flats, period conversions, riverside apartments and more contemporary developments.
That variety is part of Barnes’ appeal, but it also means buyers shouldn’t assume that every property, or every mortgage, will be treated in exactly the same way.
How Much Can You Borrow to Buy in Barnes?
Before beginning a serious property search, it’s worth getting a clear idea of how much you can realistically borrow.
Mortgage affordability goes well beyond multiplying your salary by a particular number.
Lenders can consider your:
- basic salary
- bonus and commission
- self-employed income
- company profits and dividends
- existing mortgages
- loans and other credit commitments
- dependants and regular expenditure
- deposit
- mortgage term
- overall financial circumstances
The way lenders assess those factors can differ considerably.
This can be particularly relevant for buyers in Barnes, where larger mortgage requirements are common.
Arranging a Large Mortgage in Barnes
Buying a higher-value property can introduce considerations that aren’t always as important with a smaller mortgage.
Once borrowing reaches £500,000, £1 million or more, differences between lenders can become increasingly significant.
Some lenders may place restrictions on maximum loan-to-value at larger loan sizes. Others may assess affordability differently or have specific criteria for high earners and borrowers with more complex financial circumstances.
Depending on the client, there may also be options beyond a conventional high-street mortgage.
Specialist lenders and private banks can sometimes take a more individual approach to clients with significant assets, complex income, investment portfolios or particularly large borrowing requirements.
The important point is that the lender offering the most attractive headline mortgage rate isn’t automatically the lender offering the most appropriate overall solution.
For a large mortgage, the structure of the borrowing, fees, flexibility, early repayment provisions and how the lender assesses your circumstances can all matter.
Using Bonus or Commission Income for a Barnes Mortgage
Many of the professionals we work with across London receive a meaningful proportion of their earnings outside their basic salary.
That might include:
- annual or quarterly bonuses
- commission
- overtime
- allowances
- restricted stock units or share-based remuneration
- other variable income
Not every mortgage lender treats this income in the same way.
A lender may look at how long you’ve received it, whether it is guaranteed or discretionary, and how consistent it has been over previous years.
They may also differ in how much of that income they’re prepared to use for mortgage affordability.
If variable earnings represent a substantial part of your total remuneration, choosing the right lender can therefore make a considerable difference to your borrowing options.
Getting a Mortgage in Barnes When You’re Self-Employed
Self-employed buyers can face similar differences between lenders.
If you’re a sole trader, lenders will generally assess your trading income using evidence such as tax calculations and accounts.
For limited company directors, things can become more nuanced.
Some lenders may focus on salary and dividends, while others may be prepared to consider retained profits or your share of company profit where their criteria allow it.
Length of trading history can also influence the options available.
The important thing is not to assume that being self-employed automatically means you can borrow less.
Often, it’s about identifying a lender whose assessment fits the way your business and income are structured.
How Much Deposit Do You Need to Buy in Barnes?
There isn’t a Barnes-specific minimum deposit.
The amount required will depend on the value and type of property, the size of mortgage you’re looking for and your individual circumstances.
Higher loan-to-value mortgages can be available to eligible borrowers, while providing a larger deposit may open up additional mortgage products or potentially more competitive pricing.
For higher-value purchases, lender criteria can also change as the mortgage amount increases.
That’s why we’d avoid starting with a blanket assumption that you need a particular percentage deposit simply because you’re buying in Barnes.
Instead, look at the purchase price, your available funds and your mortgage options together.
Getting Mortgage-Ready Before Making an Offer
When you’ve found a property you want, being financially prepared can make the next stage considerably easier.
Before making an offer, we’d recommend having a clear understanding of:
- how much you can realistically borrow;
- how much deposit you want to contribute;
- your approximate monthly repayments;
- the additional costs involved in purchasing; and
- any aspects of your income or circumstances that might require a particular lender.
An Agreement in Principle can also help demonstrate that you’ve already considered the financing behind your purchase.
It isn’t a guarantee of a mortgage offer, and the property itself will still need to be acceptable to the lender, but it can be a useful part of preparing to buy.
The Property Matters Too
Mortgage applications aren’t only assessed on the person borrowing the money.
The lender also needs to be comfortable with the property.
Barnes has a diverse housing stock, and certain properties can require additional consideration from a mortgage perspective.
That might include:
- leasehold flats
- period conversions
- unusual construction
- properties requiring significant renovation
- homes with substantial acreage or unusual features
- properties close to commercial premises
- high-value or unique homes that can be difficult to compare with neighbouring sales
The lender will normally arrange a mortgage valuation to determine whether it considers the property suitable security for the loan.
If the valuation comes back below the agreed purchase price, a mortgage down-valuation, it can affect the loan-to-value and potentially the amount of deposit required.
If there’s anything unusual about the property you’re considering, it can be worth raising it with your mortgage adviser before submitting an application.
Remortgaging a Property in Barnes
If you already own a home in Barnes, your mortgage should still be reviewed periodically rather than simply left to run in the background.
One of the most common reasons to remortgage is that an existing fixed or tracker deal is approaching its end.
If you take no action, you may move onto your lender’s Standard Variable Rate. Depending on the lender and the products available at the time, this could mean paying more than necessary.
But getting a new rate isn’t the only reason people remortgage.
Barnes homeowners may also consider reviewing their mortgage because they want to:
- release equity from their property;
- fund an extension or major renovation;
- consolidate existing borrowing where appropriate;
- change the mortgage term;
- move from interest-only to repayment, or vice versa where suitable;
- add or remove someone from the mortgage;
- restructure their finances following a change in circumstances.
The right solution could involve moving to another lender, but it doesn’t necessarily have to.
Your existing lender may offer a new product through a product transfer, which can sometimes be simpler than completing a full remortgage.
Comparing both routes can help determine which makes more sense overall.
When Should You Start Looking at Remortgage Options?
You don’t necessarily need to wait until your existing mortgage deal ends.
Many lenders allow a new mortgage product to be secured several months in advance.
Starting the conversation early gives you time to understand your options rather than making a decision under pressure immediately before your current deal expires.
It can also provide an opportunity to review whether your circumstances have changed since you arranged the original mortgage.
Perhaps your income has increased. You may have built additional equity in the property. Your family circumstances might have changed, or you may be planning renovations or another property purchase.
A remortgage review should consider those wider circumstances rather than focusing exclusively on the interest rate.
Releasing Equity From a Barnes Property
For homeowners who have built significant equity, remortgaging can sometimes provide a way of releasing part of it.
The money might be used to fund:
- a property extension or refurbishment
- the purchase of another property
- a deposit for a buy-to-let investment
- financial support for family
- other significant expenditure
However, releasing equity increases the amount secured against your home and could increase your monthly repayments or the overall interest you pay.
The lender will also reassess affordability based on the new mortgage amount.
It’s therefore something that should be considered as part of your wider financial position rather than simply because equity is available.
Should You Remortgage or Stay With Your Existing Lender?
There isn’t one answer that works for everyone.
Staying with your current lender through a product transfer can sometimes offer a straightforward route to a new mortgage deal.
Moving to another lender through a remortgage may provide different rates, criteria, features or borrowing options.
The important thing is to compare the overall cost and suitability rather than assuming that either staying or switching will automatically be better.
For larger mortgages, even relatively small differences in rates and fees can have a meaningful financial impact.

FAQ: Buying Property in Barnes
Can I get a £1 million mortgage to buy a property in Barnes?
Potentially, yes. £1 million+ mortgages are available from a range of lenders, subject to affordability, loan-to-value, the property and your individual circumstances.
For larger mortgages, it can be worth considering high-street banks alongside specialist and private-bank options where appropriate.
Can I use bonus income towards my mortgage?
Potentially. Many lenders will consider bonus and commission income, although how much they'll use and the history they require varies. If a significant proportion of your earnings comes from variable pay, lender selection can have an important effect on affordability.
Can I get a mortgage in Barnes if I'm self-employed?
Yes. Self-employed applicants can access mortgages from mainstream and specialist lenders. How your income is calculated will depend on factors including your business structure, trading history and the lender's individual criteria.
When should I start looking at remortgaging?
It can be worth reviewing your options several months before your existing deal expires. Some mortgage offers can be arranged in advance, giving you time to compare your options and plan the switch appropriately.
Can I release equity from my Barnes home?
Potentially. If the property's value and your financial circumstances support additional borrowing, you may be able to release equity through a remortgage or further advance. Increasing your mortgage does carry additional costs and risks, so affordability and the purpose of the borrowing should be considered carefully.
Is a product transfer better than remortgaging?
Not necessarily. A product transfer with your existing lender can sometimes be simpler, while moving lender may provide different rates, criteria or features. Comparing the overall cost and suitability of both options is generally more useful than looking at the headline rate alone.
