Wandsworth is one of South West London’s most established residential areas, combining period homes, modern developments, green spaces and excellent connections into central London.
It is also an area where buying a property can involve some substantial financial decisions.
From first-time buyers purchasing flats to families moving into larger homes and professionals arranging £1 million+ mortgages, the borrowing requirements of Wandsworth buyers can vary enormously.
At Oportfolio, we’re based on Putney Bridge Road in the London Borough of Wandsworth and have extensive experience helping clients buy, move and remortgage throughout the local area.
If you’re considering buying a property in Wandsworth, understanding your mortgage position early can make the entire process considerably easier.
Buying a Property in Wandsworth
One of the attractions of Wandsworth is the variety of property and neighbourhoods available.
Wandsworth Town combines Victorian and Edwardian streets with newer apartment developments, while areas around East Hill and West Hill offer larger period properties and family homes.
Towards the Thames, developments around Wandsworth Riverside provide more contemporary apartment living, while nearby Putney, Battersea, Earlsfield, Southfields and Tooting each offer their own distinct property markets.
Wandsworth Common is another major attraction, particularly for buyers looking for green space while remaining well connected to central London.
That variety means there isn’t really a typical Wandsworth buyer, or a typical Wandsworth mortgage.
The right way to finance a purchase will depend on the property, the amount you need to borrow and your individual financial circumstances.
How Much Can You Borrow for a Property in Wandsworth?
This is one of the most important questions to answer before you start seriously looking at properties.
Mortgage affordability isn’t simply a case of multiplying your salary by four or four-and-a-half.
Different lenders have different affordability models and can assess the same applicant very differently.
They may consider your:
- basic salary;
- bonus and commission;
- self-employed or company income;
- existing mortgage commitments;
- loans and other credit;
- dependants;
- regular expenditure;
- deposit;
- proposed mortgage term; and
- overall financial circumstances.
For some borrowers, relatively small differences in the way a lender assesses income can result in a significant difference in borrowing capacity.
That’s particularly relevant in London, where the mortgage required to purchase the right property can be substantial.
Before deciding what your property budget should be, it can therefore be useful to establish what lenders are actually prepared to offer based on your circumstances.
Getting a Large Mortgage in Wandsworth
Higher property values mean many Wandsworth buyers need larger mortgages.
If you’re looking to borrow £500,000, £1 million or more, the mortgage market can start to work differently.
Lenders may apply different affordability calculations, loan-to-value limits or criteria depending on the size of the mortgage.
For high earners, the situation can become even more interesting.
Some lenders may potentially offer enhanced income multiples to borrowers who meet particular income and eligibility requirements, while others may take a more conservative approach.
And for particularly large or complex cases, the most appropriate solution isn’t necessarily going to come from the lender you bank with.
Depending on your circumstances, high-street banks, specialist lenders and private banks may all be worth considering.
A large mortgage should therefore be looked at as more than simply finding the lowest advertised interest rate.
Affordability, fees, flexibility, early repayment charges, the treatment of your income and your longer-term plans can all influence which mortgage is most suitable.
Getting a Mortgage in Wandsworth When You’re Self-Employed
Self-employment doesn’t automatically make getting a mortgage more difficult.
It does, however, make lender selection particularly important.
If you’re a sole trader, lenders will usually assess income using evidence such as your accounts and tax calculations.
Limited company directors can be treated differently.
Some lenders primarily consider salary and dividends. Others may be willing to look at your share of company profits or retained profit where their criteria allow.
Trading history can also matter, although having less than the traditional two or three years of accounts doesn’t necessarily mean there are no mortgage options available.
The important thing is to find a lender whose criteria fit the reality of your finances rather than trying to make your finances fit a particular lender.
Using Bonus or Commission Income for Your Mortgage
Wandsworth is home to many professionals whose total earnings aren’t represented by their basic salary alone.
Bonuses, commission and other variable remuneration can form a substantial part of annual income.
Mortgage lenders don’t all treat that income in the same way.
One lender may require a longer track record of bonus payments, while another may be comfortable using a shorter history. They can also differ in the proportion of variable income they’ll include within their affordability assessment.
For example, two applicants with exactly the same salary and bonus could potentially receive different maximum borrowing figures simply because their applications have been assessed by different lenders.
If bonus or commission makes up a significant part of your earnings, it’s worth understanding those differences before assuming how much you can borrow.
How Much Deposit Do You Need to Buy in Wandsworth?
There isn’t a specific deposit requirement for buying property in Wandsworth.
The amount you’ll need will depend on your circumstances, the property’s value and type, the mortgage amount and the lender.
Higher loan-to-value mortgages may be available to eligible buyers, including first-time buyers with relatively small deposits.
Providing a larger deposit, however, can potentially reduce the amount you need to borrow and provide access to a wider selection of mortgage products.
For larger mortgages, lenders may also have different maximum loan-to-value limits depending on the amount being borrowed.
Rather than deciding that you need a particular percentage because you’re buying in London, it’s better to assess your deposit and borrowing requirements together.
Buying Your First Property in Wandsworth
Buying your first home in Wandsworth can feel daunting, particularly when you’re trying to understand affordability, deposits and the mortgage process at the same time.
One of the best things you can do is establish your financial position before finding the property.
That means understanding:
- how much you could realistically borrow;
- how much deposit you’re comfortable contributing;
- what the monthly mortgage payments could look like;
- the additional costs involved in purchasing; and
- whether anything about your circumstances could affect your choice of lender.
You may also want to obtain an Agreement in Principle.
An Agreement in Principle isn’t a guarantee that you’ll receive a mortgage offer, but it provides an initial indication of potential borrowing and can help demonstrate to an estate agent that you’ve already considered how you’ll finance the purchase.
Don’t Forget the Other Costs of Buying
Your mortgage deposit is only one part of the cost of purchasing a home.
You’ll also need to consider expenses such as:
Stamp Duty Land Tax
The amount payable will depend on the purchase price and your circumstances, including whether you’re a first-time buyer or already own another property.
Legal fees
Your solicitor or conveyancer will carry out the legal work associated with the purchase.
Survey costs
You may choose to arrange a property survey in addition to the lender’s mortgage valuation.
Mortgage and valuation fees
Depending on the product and lender, there may be arrangement, booking or valuation fees.
Service charges
If you’re buying a leasehold apartment, understand the ongoing service charge and any other costs associated with the development.
Renovation and moving costs
Period homes can be one of the attractions of Wandsworth, but factor any necessary renovation or maintenance into your overall budget.
Looking at the full cost of homeownership gives you a much more useful picture than considering the deposit and monthly mortgage payment alone.
The Property Can Affect Your Mortgage Too
Mortgage approval isn’t based solely on your finances.
The lender must also be comfortable with the property you’re buying.
Wandsworth has an incredibly varied housing stock, so this can occasionally become an important part of the mortgage process.
Lenders may take additional interest in properties such as:
- period conversions;
- flats above or close to commercial premises;
- properties with short leases;
- unusual construction;
- properties requiring substantial renovation;
- certain new-build apartments; and
- properties with unusual features or layouts.
The lender will normally arrange a mortgage valuation before issuing its final offer.
One issue that can arise is a down-valuation, where the lender’s valuer considers the property to be worth less than the price you’ve agreed to pay.
That can affect your loan-to-value and potentially mean you need a larger deposit, renegotiate the purchase price or consider another approach.
If there’s something unusual about a property you’re interested in, it’s worth discussing it with your mortgage adviser as early as possible.
What Happens Once Your Offer Is Accepted?
Once you’ve agreed a purchase, the mortgage process generally moves through several stages.
1. Confirm the mortgage
Your adviser can review the property and your circumstances before confirming the lender and mortgage product you’re going to apply for.
2. Submit the application
The full mortgage application is submitted alongside the supporting documents required by the lender.
3. Mortgage valuation
The lender assesses the property to ensure it’s acceptable security for the mortgage.
4. Underwriting
The lender reviews your income, expenditure, credit profile and supporting documentation.
They may ask additional questions or request further evidence before making a decision.
5. Mortgage offer
If the application and property are acceptable, the lender issues a formal mortgage offer.
6. Exchange and completion
Your solicitor handles the legal process before contracts are exchanged and, ultimately, the purchase completes.
A good mortgage adviser should remain involved throughout this process rather than disappearing as soon as the application has been submitted.
What If Your Mortgage Isn’t Straightforward?
Not every mortgage application fits neatly into a lender’s standard criteria.
Perhaps you’re:
- self-employed;
- receiving significant bonus or commission income;
- still within a probation period;
- buying before selling your current home;
- returning to the UK after living overseas;
- purchasing an unusual property;
- arranging a mortgage of £1 million or more; or
- dealing with several of these things at once.
This is where understanding lender criteria becomes particularly valuable.
A declined application doesn’t necessarily mean that you can’t get the mortgage. Sometimes it simply means the application wasn’t suited to that particular lender.
Identifying potential complications before applying can save considerable time and reduce the risk of approaching lenders that aren’t appropriate for your circumstances.
Remortgaging a Property in Wandsworth
If you already own a property in Wandsworth, it is worth reviewing your mortgage before your existing deal comes to an end.
You don’t necessarily need to wait until the final few weeks.
In many circumstances, mortgage options can be explored and potentially secured several months before an existing deal expires.
A remortgage review can also be useful if you want to:
- raise additional funds;
- finance renovations or an extension;
- change your mortgage term;
- restructure existing borrowing;
- release equity;
- add or remove someone from the mortgage; or
- review whether your current mortgage still suits your circumstances.
Moving to another lender isn’t always necessary.
Your existing lender may offer a new product through a product transfer, so it’s worth comparing the options available from your current provider with the wider mortgage market.
