What is mortgage affordability?
Mortgage affordability refers to whether a borrower has the means to pay off a mortgage loan each month and still have enough money left over to cover their other outgoings.
Lenders will calculate this by assessing your income and outgoings, as well as other factors such as the amount of deposit you have and your credit report.
How much mortgage can I get approved for?
Every lender is different, but most use their own affordability models based on net disposable income, and then apply a cap based on income multiples.
Typically, the amount you can borrow is determined by multiplying annual salaries.
Below is an example of how different multiples can affect how much how much mortgage you can get.
|Income||3x Income||4x Income||5x Income||6x Income|
The above table is for comparative purposes only. You should talk to your lender or broker for the most up-to-date information for your circumstances.
How much mortgage can I get approved for if I’m buying with someone else?
It is usually a multiple of the combined salary of everyone who’ll be named on the mortgage. If you’re buying a property with someone else, whether that’s a partner, a family member or a friend, the lender will tally up your combined income.
If you are applying for a mortgage with someone else, lenders will take both incomes into account when calculating your affordability. This usually means you’ll be able to afford a higher mortgage as most mortgage lenders are willing to offer home loans based on 3-4 times the total salary of each applicant, some will go up to x5, and a minority will stretch to x6, under the right circumstances.
To find out how much you can afford, it’s always best to talk to one of the advisors we work with, they’re experts when it comes to finding mortgages, even if you have bad credit. Make an enquiry for a free, no obligation chat.
Is salary the only thing that affects my mortgage affordability?
No! Most lenders would only be willing to offer you a mortgage based on a higher income multiple (x5 or x6 your salary) if they deem the level of risk acceptable.
Most lenders assess the amount of risk based on the following factors:
- The amount of deposit you have
- Your credit report
- The property type
- Your age
- Your employment capacity
- Your outgoings
Put simply, the more deposit you’re able to put down, the lower the risk the lender is taking on. Because of this, it’s often worth putting down more than the minimum if you’re hoping to convince a mortgage provider to offer you a higher income multiple.
Most lenders will expect a minimum of 10% deposit for a residential property, although some will be happy with just 5% under the right circumstances.
You should also keep in mind that the more deposit you’re able to save up, the less you will need to borrow to buy the property you’ve got your eye on.
Bad credit can drive up the level of risk a mortgage application involves, especially if it’s a severe issue such as a recent bankruptcy or repossession. If you have any of these problems on your file, some lenders might offer unfavourable rates, lower income multiples or even turn you away altogether.
If you have any adverse against your name, it’s important to speak to a whole-of-market advisor, like the ones we work with, as this is the best way to ensure you’ll end up with the best deal that you qualify for.
They know the specialist providers who take a more flexible approach to mortgage customers with a bad credit score, or have a history of credit problems. Using this knowledge, a whole market broker may be able to find lenders willing to offer you a higher mortgage, even taking your bad credit into account.

How much you can get for a mortgage loan will also depend on the type of property you’re buying. For example, some lenders consider non-standard construction buildings (e.g. anything with a thatched roof or timber frame) to be higher risk.
To allay their concerns, some lenders may offer unfavourable rates for these properties or lower income multiples, while others might turn you away. So it’s important to seek specialist advice before pressing ahead.
If you’re looking for a mortgage based on a higher income multiple in later life, you might find it more difficult to get the deal you want, due to there being fewer approachable lenders.
Some mortgage providers won’t lend to anyone over 75, others over 85. A small handful have no upper age limits, as long as they’re confident the borrower can meet the monthly payments during their retirement.
The advisors we work with have access to every lender on the market. They have the tools, knowledge and experience to connect you with the mortgage lender best positioned to offer mortgages based on higher income multiples to borrowers who are in, or approaching, their retirement.
They can also discuss later life mortgage products, such as equity release with you as these could also make affordability less of an issue.
If you’re self-employed or make a significant amount of your income through things like bonuses, commission or regular overtime, a specialist lender is often required to get the best rates and the highest income multiples.
You can read more about mortgages for self-employed borrowers or make an enquiry to speak with one of the experts we work with about how to get the best rates and deals if your income is non-standard.
Having significant outgoings such as dependent children or outstanding loans to pay can affect the amount some lenders are willing to let you borrow.
There are no hard and fast rules on how heavily this can impact your borrowing capacity. What some lenders consider a risky debt-to-income ratio, others might be comfortable with.

How much mortgage can I afford as a first-time buyer?
Affordability for first-time buyer mortgages is calculated in exactly the same way as for standard mortgage products. Some providers will cap their lending at 3-4x your salary, others 5x and, under the right circumstances, a minority will lend up to 6x.
There are also a number of government schemes for first-time buyers that help make a mortgage more affordable, including…
- Lifetime ISAs
- Help to Buy equity loan scheme
Help to Buy ISAs
*UPDATE: The Help to Buy: ISA scheme is now closed to new applicants. You can read more about this in our guide.
Help to Buy equity loans
The equity loan scheme is available to first-time buyers or existing homeowners who want to buy a ‘new build’ house.
The purchase price must be no more than £600,000. Using this scheme, you can borrow 20% of the purchase price interest-free for the first five years, but you need to have saved at least a 5% deposit.
How much mortgage can I borrow for a mortgage with Help to Buy?
Help to Buy involves the borrower putting in 5% deposit, then taking an interest-free equity loan from the government for 20%, and a 75% mortgage with a participating lender to cover the remainder of the amount you need.
You can buy any new-build property up to £600k in value, with no fees or interest to pay on the equity loan for the first 5 years of borrowing, after which you are charged a very reasonable 1.75% in the 6th year, increasing 1% + RPI every year onwards.
As it’s an equity loan, when you sell the property you give the government back their share of any profit – so if you bought for £100k using a 20k equity loan and then sold the property for £120k a few years later, you’d need to repay 20% of the £120k = £24k.

How much could I get a mortgage for a buy-to-let?
Buy-to-let mortgages (BTL) work in a similar way to residential mortgages, although the fees, rates and required deposit amounts tend to be higher. Minimum acceptable deposits tend to vary between 20-40% of the property value with most buy-to-let mortgage lenders..
In addition, most BTL loans are interest-only, meaning that borrowers repay the monthly interest rates on their principal balance only and repay the capital in full once their mortgage term ends.
Moreover, the amounts that can be borrowed are calculated according to expected rental incomes. Most lenders will stress-test incomes between 20-30% higher than monthly payments to cover all eventualities, such as periods without paying tenants.
How much could I borrow for a second home?
Affordability assessments work in a similar way to residential mortgages, with incomes, outgoings and credit scores all scrutinised thoroughly.
Most mortgage lenders tend to be more cautious when assessing borrowers for a second home as they will need to be satisfied that customers are capable of servicing monthly repayments on both their primary and secondary homes.
Models for determining this vary from lender to lender, although many will cap the loan to value (LTV) ratio at around 75-85% so will often charge higher deposits than for conventional loans.
You may also find that the number of lenders who are prepared to lend against second properties is much lower than for other mortgages.
How much can I borrow with a guarantor mortgage?
Lenders are often willing to allow customers to borrow more on a guarantor mortgage than if they were applying for a standard residential mortgage.
Home loans with a 100% loan to value (LTV) are available from some lenders if a family member or friend has agreed to act as a guarantor for you, which basically means you can borrow enough to cover the full amount you need.
Moreover, some providers might be more comfortable offering a higher income multiple (x5-6 your salary) if you have a guarantor behind you, providing the guarantor passes all their affordability checks.
You can read more about guarantor mortgages and how they work or make an enquiry and we’ll connect you with one of the expert brokers we work with. They will be able to answer all your questions and help you find the right mortgage solution based on your circumstances.
How much mortgage can I borrow for a property in London?
Although property prices are generally higher in the UK capital, the amount you can borrow for a residential property would be assessed in exactly the same way as it would for a home anywhere else in the country.
Location would only be a factor if you were purchasing a buy-to-let property, as the location of the property can have an impact on the projected rental income. With this in mind, it may be possible to borrow more for a buy-to-let property in a prime location in London than for one elsewhere in the UK.
