A £70k mortgage is below the national average, but it pays to prepare when applying for finance. Here you will learn how to work out the repayments on a mortgage of this size, apply for one and save money in the process.
What are the average repayments on a £70k mortgage?
The average monthly repayments on a £70,000 mortgage are around £369. This is based on a capital repayment mortgage taken over 25 years, with an interest rate of 4%, which is representative of the UK market right now.
Paying this amount for the duration of the term would mean repaying a total of £110,846, but the exact cost of your mortgage may vary. There are a range of different rates, term lengths and mortgage types available, and the deals you qualify for may differ to this example.
Work out your mortgage repayments
You can work the potential repayments on a £70k mortgage yourself by using our calculator below. Simply fill out the fields for quick results.
This calculator can be used to compare how your payments might look across different interest rates and term lengths, as well as with an interest-only repayment type.
Factors that will impact your repayments
The main factors that will determine what your repayments will be are the interest rate, the term length and the mortgage’s repayment type. We will now explore each of these variables in detail, complete with example calculations a mortgage amount of £70k to add context.
Interest rate
The interest rate you qualify for will be the main factor that shapes the repayments on your £70,000 mortgage. Lenders will decide this based on the amount of deposit you have, the overall strength of your application and the type of product you choose.
At the time of writing, longer fixed-rate mortgages tend to have lower rates than variable deals, and mortgages with product fees have lower ones than fee-free deals.
The table below shows how the rates on a £70k capital repayment mortgage can vary across different rates. A term length of 25 years was used for example purposes.

Term lengths
Longer and shorter mortgage terms than the standard 25 years are available. Short terms mean higher monthly repayments but can be cost-effective in the long run, as you would have fewer interest instalments to pay and would settle your mortgage debt earlier.
Taking a £70k mortgage out over a longer term would mean lower monthly repayments but your mortgage would cost more overall due to the extra interest payments. The table below illustrates the impact of term length on a capital repayment mortgage with a 4% rate.

Repayment type
Most mortgages in the UK are taken out on a capital repayment basis. The main alternative to this is an interest-only mortgage, where only the interest has to be paid each month and the outstanding debt is typically taken care of at the end of the agreement.
The table below shows what the repayments on a £70k interest-only mortgage would look like across different rates, and a term length of the standard 25 years.

| Monthly Overpayment | New Mortgage Term | Total Interest Paid | Total Interest Saved |

| £50 | 20 Years, 4 Months | £32,354 | £8,492 |

How much income do you need to get a £70k mortgage?
You would need to earn just over £15,550 per year to qualify for a mortgage of £70,000. This is because most UK mortgage providers cap your maximum borrowing at 4.5 times income. If your salary falls short of this amount, a broker could help you find a lender who stretches to 5-6 times salary and allows applicants to declare supplement income.

FAQs
The repayments on your £70,000 mortgage are just one of the costs you should take note of when drawing up your plans. Other costs and fees will need to be factored in when you are totting up the overall costs of your home finance. The usual mortgage costs and fees are:
- Product fees: Can range between nothing and £2,000. Fee-free deals often come with higher rates, but the fee itself can sometimes be added to the mortgage.
- Booking fee: An admin cost as part of the mortgage application process. It can range between £99-250 and is sometimes rolled into the product fee.
- Valuation fee: Some lenders will expect you to foot the cost of having the property you’re buying valued, and this can set you back between £250-1,500.
- Telegraphic transfer fee: A small fee to cover the cost of transferring your mortgage funds to your solicitor so the deal can be closed, usually between £25 and £50.
- Account fee: Another admin cost, usually between £100 and £300, to cover the set up, maintenance and eventual closure of your mortgage account held by the lender.
- Stamp duty: See our stamp duty guide to find out how much your bill will be and whether you qualify for exemption.
The deposit amount required will be determined by the property’s value. You will need at least 5-10% of it to pay upfront, with the £70,000 mortgage to cover the rest.
Usually more than a residential mortgage would cost as rates for buy-to-let mortgages can be slightly higher, but the way your mortgage repayments are calculated is no different for buy-to-let, so you can use our calculator to accurately crunch some numbers.
Most buy-to-let mortgages are taken out on an interest-only basis.
You would need to factor in the typical minimum deposit amount of 5%, which in this case would be £3,500, and deduct this from the property's purchase price. This means that you would need to take out a mortgage of £66,500 to buy a house with a price tag of £70k.
At this price point, properties are often older terraced houses, flats above shops, or studio apartments. Some of these may be of non-standard construction (e.g., concrete frames, timber-clad, or thatched roofs).
Lenders are generally more cautious with these property types regardless of the loan size. You may need a specialist lender that understands the resale risk of unconventional properties to secure your £70,000 loan.
