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?
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, reflective of the market conditions at the time of writing.
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.
The table below shows how much a £90,000 mortgage will cost each month and overall when taken out on an interest-only basis with a term length of 25 years.

How much salary do you need to get a £90k mortgage?
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.
You can use our calculator below to get an idea of whether you earn enough income to qualify for a £90,000 mortgage.

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:
-
Contribute a larger deposit: Increasing your initial deposit reduces the amount you need to borrow and, crucially, lowers your loan-to-value (LTV) ratio. Lenders view a lower LTV more favourably, which can grant you access to a wider range of products with more competitive interest rates.
Increasing your deposit could help you reduce you borrowing, but equally it can improve your buying power. This table shows the property value available to you with a £90,000 mortgage, depending on the size of your deposit, and therefore, your LTV:
| Loan-to-Value (LTV) | Minimum Deposit Required | Property Purchase Price |
| 95% LTV | £4,737 | £94,737 |
| 90% LTV | £10,000 | £100,000 |
| 85% LTV | £15,882 | £105,882 |
| 80% LTV | £22,500 | £112,500 |
| 75% LTV | £30,000 | £120,000 |
| 60% LTV | £60,000 | £150,000 |
-
Enhance your creditworthiness: Taking proactive steps to improve your credit profile before applying can have a significant impact on the rate you're offered. Settling any manageable debts, ensuring all your payments are consistently on time, and allowing historical credit issues to fall off your record will all help to strengthen your application.
-
Extend the mortgage term: Spreading your loan over a longer period is a common strategy to lower your monthly repayments, which can help with immediate affordability. It is important to remember, however, that this will increase the total amount of interest you pay over the full life of the loan.
-
Explore an interest-only option: This type of mortgage offers lower monthly payments as you are only servicing the interest on the debt. However, you must have a credible and robust strategy (a ‘repayment vehicle’) in place to clear the capital balance at the end of the term. Seeking professional advice from a mortgage broker is essential before considering this path.
- A part and part mortgage: This combines both a repayment and an interest-only mortgage, allowing you to make a monthly saving on your repayment, but without the burden of repaying the full loan at the end of the mortgage.

FAQs
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.
The amount of deposit you will need is not determined by the mortgage amount, in this case £90k, but the property’s purchase price. You will need at least 5-10% of the purchase price to get approved for a mortgage. For example, you could buy a £100,000 property with a £90,000 mortgage and a £10,000 deposit, as £10,000 would be 10% of the purchase price.
They would be calculated in exactly the same way as they would be for a residential mortgage, but interest rates can be higher in this corner of the market, and most buy-to-let mortgages are taken out on an interest-only basis so landlords can keep their costs down.
With these factors in mind, a typical monthly repayment on a buy-to-let mortgage at the time of writing would be around £413. This is based on an interest-only mortgage with a 5.5% interest rate, a 25-year term length and a borrowing amount of £90,000.
Given that you will need at least 5% of the property's value to put down as a deposit - which in this case would be £4,500 - you would need to take out a mortgage for £85,000. In very cases, it may be possible to borrow the full £90k on a 100% LTV mortgage deal.
Yes, £90,000 is one of the more accessible loan amounts for single mortgage applicants. As long as your salary is around £20,000–£22,000 and your credit score is healthy, many high-street lenders will be happy to offer this amount. This makes it a popular choice for first-time buyers or those looking to downsize.
