What is the maximum amount you can expect to pay on a £450k loan?

How much does a mortgage cost for a £450k house? This is not a simple question to answer. The amount you pay will depend on many factors.

Different lenders have different mortgage eligibility criteria. Your individual circumstances (discussed more in detail later) will impact the interest rate offered to you, as well as the monthly payments and the total cost of a £450k loan.

But, before looking at these key factors, see our mortgage repayment calculator below. It will give an idea of what your repayments might be.

Interest rates on a £450,000 mortgage

The most important factors that will impact how much you pay for a £450,000 mortgage monthly are the interest rate and the length of the term.

Mortgage term lengths available

The length of your mortgage term significantly impacts the amount of a mortgage. This is not just based on monthly payments but also the total cost of interest at its end.

This table* shows how reducing the term length can impact your monthly mortgage payments and total interest paid.

Below is an example of a £450k mortgage at a 3.5% standard interest rate:

This scenario saves you £148,397 by having a £450k mortgage for a 15-year term instead of 30, and the cost of a £450k loan.

How much does a mortgage for £450,000 cost?

Income required for a £450,000 mortgage

A mortgage advisor considers income important because it indicates whether your salary is sufficient to pay a £450,000 mortgage.

The DTI ratio is a measure of affordability. It measures your monthly income and subtracts your outgoings.

A lower DTI is better because you have fewer financial obligations and more money to repay a mortgage.

Most lenders will limit the amount they loan you to get a mortgage based on your annual income. While most lenders limit loans to 3-4x your income, some providers will allow you to borrow up to 5x. Some providers may extend loans up to 6x of your income.

Lenders are more likely to lend you a secured loan to secure a mortgage. Lenders will often lend 10x your income or more.

Because you have more money invested, lenders are more open to discussing your other financial circumstances.

LTV (Loan to Value)

The loan to value of a property (how much you want it to be financed relative to its market value) will impact how lenders view you.

If you deposit 25% on the house, you might get a better interest rate than if it was 5%.

Many residential mortgage lenders offer up to 85% loan-to-value (LTV), while others can extend to 90%. A few lenders accept 95% LTV (5% deposit).

Credit history

Mortgage providers are less likely to lend to people with poor credit histories.

Some lenders may place restrictions or requirements on you to consider you. These could include higher interest rates, income requirements, or limits on the amount they will lend.

Each person has their own standards about what is acceptable and unacceptable. This is often based on the date of the incident and/or the severity.

These are the most common types of adverse (from lowest risk to highest):

  • Credit score low
  • Late payments.
  • Mortgage arrears.
  • Defaults.
  • County Court Judgements (CCJs).
  • Debt Management Plans (DMPs).
  • Individual Voluntary Arrangements (IVAs)
  • Bankruptcy.
  • Repossession.

Due to their age meaning they are at higher risk, particularly for long-term loans, older borrowers may have a harder time getting approved for a mortgage.

While some providers will not lend to retirees, others have minimum terms or maximum lending limits. Many providers won’t lend to people over 75 years old, while others limit lending to 80/85.

But not everyone is subject to an age limit. We are a market broker and have access to more than 100 mortgage providers. We then search the market to find the best £400k mortgage interest rates. Visit our later life lending page for more information.

Types of employment

You may be considered a higher risk if you’re self-employed or are in a different employment category. This could impact the interest rates offered to you.

Providers will typically require a minimum of one year’s worth of accounts if you are self-employed. Some prefer 3+ years, while others prefer 2. This is to make sure that your income is stable and you can afford to pay the £450k mortgage.

Lenders may also be wary of people who earn extra money through bonuses and commissions. Contract type and duration are other factors.

Many lenders specialize in home loans for those with unusual employment types. It’s not difficult to find them. Call us to speak with an expert in this field.

Type of property

Properties that can be rented as buy-to-let (BTL)

BTL properties are subject to different rules. If your £450k mortgage is intended for this type of investment, be aware of the following:

Lenders require a higher deposit than usual, typically 25%+ (75% LTV). Some lenders also have income requirements of around £25k.

Forecast rental income and the borrower’s annual salary determine mortgage affordability.

Second homes

Existing homeowners buying second home are at greater risk.

Lenders will expect that your primary residence is your priority if you take out a loan on a second property and get into financial difficulties. Borrowers will need to show that they can finance two mortgages simultaneously.

You may need to make a bigger deposit if you are looking to get a £450k mortgage for a second house. You may need to meet minimum income requirements and undergo more detailed affordability assessments.

Types of construction that are not standard

Non-standard construction is any property that differs from a “house made from brick or blocks walls”.

These properties are considered less stable investments, which often means fewer lenders available and fewer buyers.

Some lenders will consider unusual property types. Start your application online below:
