If you’re looking for a relatively low mortgage of £20,000, here we tell you who might lend to you, how much you might pay and what factors to consider.

If you think you’re well within the borrowing eligibility for a £20,000 mortgage, there will still be a number of factors to consider before you can establish exactly what your monthly payments will be.
Some lenders also set minimum loan limits, making some low-payment products harder to obtain. Here, we will explain exactly what to expect when looking for a £20k mortgage and how it will affect your pocket.
Can you get a mortgage for £20,000?
Yes, but this is considered a very small mortgage amount, and some lenders have minimum loan caps that prevent them from offering mortgages of this size. Some mortgage providers won’t go below £30,000, but the good news is that others draw the line at £20,000.
With the average house price in the UK now exceeding £350,000, it’s unlikely you will want to borrow £20k as a substantial percentage of your property.
Perhaps you have a large cash deposit on a home but need to borrow the extra money to cover the shortfall. Maybe you’re looking to make some home improvements. Or you could be hoping to buy a home through a government scheme that allows you to get on the property ladder with a relatively small mortgage.
Whatever your circumstances, it is recommended that you speak to a broker if you’re applying for a loan this small. Their guidance can help you avoid violating lenders’ minimum loan caps.

What income will you need?
The lowest income multiple for lenders is between 4 times and 4.5 times your income, so your application should be strong if your salary is at least £5,000. Some lenders also consider 5-times or 6-times multiples. Other income streams, such as pensions, rental payments, commissions, or benefits, could satisfy lenders.
These days, plenty of lenders approach mortgage approvals in a more holistic way, rather than strict rules around income. Instead, they will look at your financial situation and eligibility as a whole.

You could borrow up to
Most lenders would consider letting you borrow
This is based on 4.5 times your household income, the standard calculation used by the majority of mortgage providers. To borrow more than this, you will need to use a mortgage broker to access specialist lenders.
Some lenders would consider letting you borrow
This is based on 5 times your household income, a salary multiple you might struggle to qualify for without the help of a broker. This income multiple is not widely available to customers who are applying directly with a lender.
A minority of lenders would consider letting you borrow
This is based on 6 times your household income, a salary multiple you will struggle to get without a broker. Six-times salary mortgages are usually only available under very specific circumstances.

Monthly repayment calculations
The length of your mortgage term will make a big difference in how much you pay each month. There are a number of other factors that will affect this calculation, too, such as rates and the type of mortgage, which are covered in more detail elsewhere in this article.

Example calculations
The length of your mortgage term will greatly affect your monthly payment. Other factors, such as rates and types of mortgages, will also affect this calculation, and they are covered in more detail elsewhere in this article.
Here is an estimate based on a repayment mortgage with a 3.5% interest rate without considering fees.
| Mortgage | 5-year term | 10-year term | 15-year term |
| £18,000 | £327 | £178 | £129 |
| £20,000 | £364 | £198 | £143 |
| £24,000 | £437 | £237 | £172 |
| £30,000 | £546 | £297 | £215 |
Factors that could affect your monthly payments
There’s no one-size-fits-all when it comes to mortgages, particularly for low amounts such as £20,000, so bear in mind the following components:
Your credit history
Lenders will always look at your credit report, and decisions can be made one way or another depending on how you have previously managed your finances. That’s not to say blips in your credit file mean instant rejection, but it does mean you should be ready to deal with the hurdles that could be presented during your application.
Term of loan
As the table above suggests, the length of your mortgage term has a substantial impact on your monthly payments. For example, paying a £20,000 mortgage over 10 years will work out differently than over five.
Paying off your mortgage as soon as possible means paying less interest overall over the term and freeing yourself from the loan sooner. However, longer terms can work well if your income is low.
Interest rates
These are set individually by each product and lender. The lower the interest rate, the lower the cost of your mortgage, which is why getting your application in good shape could unlock better deals.
Types of mortgage
Even on small product loans, monthly payments are greatly affected by your mortgage type. Get good advice and educate yourself on which would be best for you: repayment or interest-only, fixed rate or tracker. Every factor should be considered.

How a broker can help you get the best deal
Professional brokers are not only for those who want specialist, complex and high-stakes mortgages. Their role is to find the best deal out there for your circumstances, no matter how much you want to borrow.
Brokers specialise in securing small mortgage loans for borrowers, such as £20,000. They have deep working relationships with lenders with no minimum mortgage amounts, increasing your chances of finding the right mortgage provider the first time.
Honest and reliable brokers, like the ones in our network, are often the best money spent when going through the mortgage process because they ultimately help you save in the long term by securing the best mortgage for you.
Make sure you find someone willing to do their research, take time to understand your circumstances, has contacts and experience, and has access to the entire marketplace. They should also be happy to help you with your paperwork.
How much deposit will you need?
You will need to have the remaining balance as the deposit if you are applying for a straightforward mortgage. Most lenders expect you to put down at least 10% of the property value as a deposit, although some will be happy with 5%.
For example, if you want to buy a home for £150,000, your cash sum deposit will be £130,000, and your £20k mortgage will make up the rest of the purchase.
This calculation will be different if you’re looking to buy a home via a government scheme. For example, the Shared Ownership scheme involves purchasing a 25 to 75% share in a house and paying the remaining share as rent.
Lenders who offer small mortgage loans
Several lenders have no lower limits or limits below £20k. Some are happy to lend small amounts, provided the purchase price is above a certain amount. For example, Skipton Building Society has no minimum loan amount but stipulates that the property value should be at least £50,000.
The opportunities for small-sum borrowing vary greatly, though. Norton Home Loans offers loans as low as £3,000 on a second-charge basis, while others, such as Metro Bank, go no lower than £50,000. Market Harborough Building Society has a whopping £200,000 minimum cap.
It’s difficult to know where to turn first, so it’s advisable to go to a broker, as they understand the market and how each lender operates in this way.
Alternatives for low mortgage borrowing
If you think getting a mortgage on a relatively low amount is unnecessary or you’d rather consider other financial products first, there are several options, such as…
- Borrowing from a family member
- Getting an unregulated loan
- Paying via credit card
- Releasing equity from another property you own
Some of these financing alternatives involve varying degrees of risk, so it is crucial to seek professional support in these circumstances.

FAQs
Not always. Remortgaging is usually more flexible, so more lenders might be willing to ignore their set lower limits and approve small loans more easily.
