How do you need to earn to get a £350k mortgage?
You need a household income of somewhere between £77,777 and £87,500 a year to get approved for a £350,000 mortgage as most lenders will cap your maximum borrowing at 4-4.5 times your annual salary, but there are ways to potentially borrow more.
If you have a strong application, some lenders might let you borrow 5-6 times your annual income, so it may be possible to qualify for a £350k mortgage earning less.

How much will the mortgage payments be?
The monthly repayments on a £350,000 mortgage are roughly £1,847, based on typical UK market conditions. To simulate these, we used a capital repayment mortgage with an interest rate of 4% and a term length of 25 years for this example calculations.
Entering this exact mortgage agreement would mean repaying a total of £554,229 over the full term, but keep in mind that mortgage repayments tend to change when you remortgage.
The exact cost of your mortgage payments will depend on the interest rate you qualify for, the term length you chose and the type of mortgage you take out.

Factors that affect the cost of a £350k mortgage
In this section we have broken down all of the factors that make up the exact cost of a £350,000 mortgage, with example calculations to add important context.
Interest rate
The interest rate a mortgage lender is prepared to offer you will depend on the overall strength of your application, largely determined by the amount of deposit you have and your credit history.
The table below shows how the cost of a capital repayment mortgage can vary across different interest rates when taken out over a standard 25-year term.
Mortgage Amount | Interest Rate | Monthly Repayments | Overall Repayment |
£350k | 3.5% | £1,752 | £525,655 |
£350k | 4% | £1,847 | £554,229 |
£350k | 4.5% | £1,954 | £583,624 |
£350k | 5% | £2,046 | £613,820 |
£350k | 5.5% | £2,149 | £644,792 |
£350k | 6% | £2,255 | £676,516 |
Term length
Most mortgage providers will give you the option to take out a longer or shorter term length than the standard 25-years. Longer mortgage agreements tend to have lower monthly payments but costs more overall due to having more interest instalments to pay.
This table shows how the monthly and overall cost of a £350k mortgage changes depending on the term length, when taken out on a capital repayment basis with a 4% rate.
Mortgage Amount | Term Length | Monthly Repayments | Overall Repayment |
£350k | 10 years | £3,544 | £425,230 |
£350k | 15 years | £2,589 | £466,003 |
£350k | 20 years | £2,121 | £509,023 |
£350k | 25 years | £1,847 | £554,229 |
£350k | 30 years | £1,671 | £601,543 |
£350k | 35 years | £1,550 | £650,879 |
£350k | 40 years | £1,463 | £702,137 |
Mortgage type
The two variables to be aware of here are the mortgage’s product type and its repayment type. Different product types, such as fixed-rate and tracker mortgages, have individual rates and fees, so the cost of your mortgage payments will vary based on your selection.
The repayment type is equally important. Most residential mortgages in the UK are capital repayment, which means you pay off some of the loan amount plus interest each month. The main alternative is interest-only, which only requires borrowers to make monthly interest payments before clearing the borrowed amount in full at the end of the term.
This table shows what the repayments on a £350,000 mortgage if it was taken out on an interest-only basis with a 25-year term and how they vary across different rates.
Mortgage Amount | Interest Rate | Interest-only Payments (Monthly) | Overall Repayment |
£350k | 3.5% | £1,021 | £656,250 |
£350k | 4% | £1,167 | £700,000 |
£350k | 4.5% | £1,313 | £743,750 |
£350k | 5% | £1,458 | £787,500 |
£350k | 5.5% | £1,604 | £831,250 |
£350k | 6% | £1,750 | £875,000 |
£350,000 buy-to-let mortgage repayments
The cost of a £350k buy-to-let mortgage would be calculated in exactly the same way as its residential equivalent but the interest rates are generally higher for this type of mortgage.
Most buy-to-let mortgages are also taken out on an interest-only basis, while capital repayment is the norm for residential properties.
With this in mind, the typical cost of a £350,000 buy-to-let mortgage would be £1,313 per month and £743,750 overall. A slightly higher interest rate of 4.5% and an interest-only repayment type were used for this example calculation.
