A £90k mortgage is below the average UK amount, but it pays to be prepared before you apply for significant finance of any kind. In this guide, you will learn how to calculate the repayments on a £90k mortgage and how to get one.
How much would a £90k mortgage cost?
Based on the UK market conditions at the time of writing (December 2024), the average monthly repayments on a £90,000 mortgage would be £475. This example calculation is for a capital repayment mortgage with a 4% interest rate, taken over a 25-year term.
The above is representative of a typical mortgage deal right now, and if you were to take out this mortgage, you would have repaid a total of £142,516 by the end of the term.
Although these figures are relevant examples, your exact mortgage costs will vary based on factors including the interest rate, term length and the type of mortgage you’re applying for.

The longer the term, the lower your mortgage repayments will be, but maxing out the term means paying more for your overall, due to the number of interest instalments increasing.
Mortgage type
The mortgage type will also have a bearing on your repayments as specific product types have different rates attached. Fixed and variable-rate mortgages come with different rates, depending on factors including how long you lock in for and whether you pay a fee.
In addition to the product type, most lenders will give you a choice of repayment type, with interest-only being the main alternative to capital repayment mortgages.

Other costs and fees
The repayments on your £90,000 mortgage are just one of the costs involved. Other costs and fees involved in taking out a mortgage include the following:
- 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 out stamp duty guide to find out how much your bill will be and whether you qualify for exemption.
Tips to help you lower your mortgage costs
You can potentially keep the repayments on a £90k mortgage to a minimum by bearing the following tips in mind:
- Put down a larger deposit: Not only would you need to borrow less, putting down extra deposit can reduce the loan-to-value (LTV) ratio and help you qualify for a lower rate.
- Improve your credit situation: Waiting for any bad credit to disappear from your credit files, paying off debts you’re in a position to clear, and paying any existing bills and credit agreements on time ahead of your application can also help you land a lower rate.
- Consider a longer mortgage term: This will reduce your monthly payments in the short term (on a capital repayment agreement), but you will be paying more in interest overall.
- Consider interest-only: Interest-only mortgages have lower monthly payments but you will need a repayment vehicle to settle the debt at the end of the term. Be sure to seek professional advice from a qualified mortgage broker before choosing this option.

FAQs
All of the mortgage applicants would need to be earning around £20,000 per year combined. This is because the majority of lenders will cap you maximum borrowing at 4.5 times annual salary - 4.5 x 20,000 = 90,000. If you don’t earn this amount, keep in mind that there are lenders who will let you borrow 5-6 times salary, under the right circumstances.
Choosing an Adviser
Selecting a qualified and experienced mortgage adviser is of great importance. To choose a suitable adviser, evaluate their qualifications, experience, and reputation, and ensure they are regulated by the Financial Conduct Authority (FCA).
Read reviews from previous clients and make sure they provide a clear explanation of the products and services they offer, as well as the fees and charges associated with them.
