What are the main factors lenders consider when assessing mortgage affordability

The lender will conduct affordability checks to determine how much mortgage you can afford and the monthly payments

Lenders have their own criteria, which can change frequently. The mortgage providers criteria are used to determine if someone is eligible for a mortgage.

They might look at you:

  • Income.
  • Employment.
  • Age.
  • Credit history.
  • Property type.

What is the maximum amount you can borrow?

Lenders will consider your annual income and use a salary calculator to calculate the amount of how much you could borrow to finance a mortgage and the monthly payments.

Mortgage lenders typically limit loans to a multiple your annual income. Mortgage lenders will limit mortgages based on your salary. So, if you are looking to get a mortgage, a lender will typically limit mortgages to 4.5x your annual income.

Some lenders will offer you up to 5x your annual income. Others may even give you 6x. These are classified as large mortgages.

Lenders may consider your application for a share mortgage if you apply with a partner. This will allow lenders to assess both incomes. For example, applicants with a combined income of £50,000 could borrow £200,000 from a lender using four x your income.

Different types of income

Lenders will consider your income when calculating your income for a mortgage. They also consider any financial obligations that might prevent you from paying your mortgage payment.

Lenders may also be less favourable to applicants with a less reliable income. You could apply if:

  • Mortgages are available to self-employed people.
  • Maternity leave
  • Variable income (such as bonuses).
  • Are you employed on a contracting or short-term basis?

You may not be able to borrow the maximum amount you are eligible for on a mortgage. There may also be fewer lenders willing to lend you a contractor loan. This doesn’t necessarily mean you can’t get a mortgage with the above.

Other sources of income

Lenders may be interested in other income sources, such as what you make and how reliable it is.

This allows them to get a true reflection of your total income, which could include:

  • Bonuses.
  • Overtime.
  • Commission – Learn how to calculate the commission income for a mortgage with our guide
  • Allowances.
  • Additional income

Not all lenders and banks will consider every income source when assessing your ability to pay. While some lenders will consider all income sources when assessing your affordability, others may only consider 50%. Some won’t even consider them at all. Mortgage calculators are a good way to gauge what you can afford.

What other considerations & calculations will the lender make?

Lenders’ mortgage affordability calculations are based on more than your income.

They will also take into account…

Your outgoings

Providers will often factor in significant outgoings to ensure you are able to pay your mortgage payments.

The following expenses would be considered by most lenders when calculating their loan amounts:

  • Credit card debt
  • Outstanding loans
  • Children and family members who are dependent
  • School fees
  • Travel expenses
  • Bills: Council Tax, mobile phone etc

Acceptable ratios between income and debt can vary from lender to lender. This is why it’s important that you seek specialist advice if your outgoings are significant. We can help you find the lender that is most likely to give you favourable results using our whole-of-market brokerages.

Credit history

Mortgage affordability checks are identical to those for applicants with good credit and those with poor credit. However, lenders may not be willing to lend to someone who has had financial difficulties in the past. Even if mortgage calculators say you can afford the monthly payments, if you have a bad credit history it will be harder for you.

What mortgage amount can you get approved with poor credit?

Lenders who accept bad credit applicants might also lend a lower amount and require a loan-to-value (LTV) ratio between 75% and 90-95% for those with less severe or more recent credit problems.

However, lenders have different criteria and will lend to bad credit mortgages. They also accept different types of credit.

There are specialist lenders that can provide mortgages for those with poor credit.

This section contains more information about bad credit mortgages.

Calculation of deposit requirements

You will need to determine how much deposit you are required to make in order to figure out your budget, how much you could borrow and mortgage repayments.

The amount of your deposit will vary depending on your financial situation, your ability to pay, the type of property you own, and your credit score.

Solid credit history can help you qualify for a deposit of 5%. However, these are more difficult to get and will only be approved under the right circumstances.

Lenders will require a minimum 5-10% deposit, which would allow you to have a maximum Loan-to-Value (LTV) between 90 and 95%.

If your situation is deemed to be riskier, you might need to deposit a greater percentage.

How does a Buy to Let mortgage calculate mortgage affordability?

Mortgages on BTL Properties still require affordability checks. However, instead of basing your affordability on your personal income and using an annual salary mortgage calculator to calculate your monthly income, lenders will consider your potential rental incomes. Most lenders will accept anywhere from 125-170% depending on your tax situation.

Providers will also ask about the number of tenants you have and whether you have the ability to pay your mortgage if your tenants are not available.
