If you’ve set a monthly mortgage budget of around £900, you might be wondering just how much you can borrow and what kind of property you can afford. The good news is that £900 per month can stretch further than you might think, depending on factors like interest rates, loan term, and your credit profile.
In this guide, we’ll show you what a £900 mortgage budget could look like in practice, how lenders assess affordability, and why speaking to a mortgage broker can help you get the most for your money. Whether you’re buying your first home or remortgaging, this article will help you confidently explore your options.
The following topics are covered below...
How much mortgage can you get for £900 a month?
With a typical residential mortgage, you could likely buy a property for around £200,000. For example, if you have a 5% (£10,000) deposit and choose a capital repayment home loan with a term of 25 years, at the time of writing, the monthly payments would be between £800 and £900, based on typical interest rates.
However, that’s just the simple answer. If you change any of the factors involved, the repayments will change. For example:
- If you increase your mortgage term to 40 years instead of the usual 25, the monthly payments could drop to between £550 and £650.
- If you were to secure a lower interest rate, your payments would drop
One thing to bear in mind, though: maximum mortgage borrowing is not based on the amount you have budgeted for your monthly payments. It’s actually based on income multiples. Use our mortgage affordability calculator below to find out how much you could potentially borrow based on the salary multiples that lenders typically use.

Our affordability calculator can tell you how much you can potentially borrow from a mortgage lender. Simply enter your total household income below and our calculator will do the rest.
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.
Get Started with an expert broker to find out exactly how much you could borrow.
Here are a few examples of mortgages you could potentially get for £900 a month, with property value and deposit amount factored in.
| Property value | Deposit amount | Mortgage term | Example rate | Approx. monthly payments |
| £200,000 | £10,000 (5%) | 25 years | 2.69% | £871 |
| £250,000 | £25,000 (10%) | 30 years | 2.39% | £876 |
| £300,000 | £45,000 (15%) | 35 years | 2.24% | £876 |
| £350,000 | £70,000 (20%) | 40 years | 2.14% | £869 |

Factors that affect your mortgage rate
A lower mortgage rate means lower monthly repayments. Here are some of the factors that affect the rate you’re offered:
Deposit size
As you can see in the chart above, the rates available to you fall a little each time you step up your deposit amount. Typical interest rates for 95% mortgages are much higher than for 80% mortgages.
Rate type
When you choose your mortgage, you’ll choose either a fixed rate (meaning your payments will stay the same for a certain period) or a variable rate (meaning your payments could go up or down if interest rates change). Fixed rates are usually set a little higher than the current variable rate.
Credit history
If you have a high credit score, you’ll usually be eligible for better rates than someone with bad credit. However, if your credit report shows events such as defaults, county court judgements, or bankruptcy, you might need a bad credit mortgage with a higher rate.
Repayment method
Mortgages are available with two types of repayment methods:
- Capital repayment: which means that you repay the loan with interest, month by month
- Interest-only: which means you pay the interest each month, while the loan capital is only due for repayment at the end of the mortgage term
Capital repayment mortgages are by far the more common choice for buyers of property they intend to live in, while interest-only mortgages (which have much higher rates) are popular with buy-to-let buyers.

How a broker can help with a £900 per month mortgage
If you want to get a mortgage with repayments of around £900 and you’d like to borrow as much as possible, there are three main ways a broker can help you:
- They understand all the factors involved in mortgage rates and repayments, and so can balance them to get you closer to the borrowing amount you need
- They have access to every deal on the market (including ones you couldn’t find on your own) and can tell you which ones someone of your age, employment status, and income could qualify for
- They can look at your finances and provide advice that’s tailored to you, based on your income, savings, etc.
If you get in touch, we’ll arrange for a broker we work with to contact you straight away for a free, initial, no obligation chat.
Other factors in getting mortgage approval
While you may be sure that you can afford monthly payments of £900, that’s not the only factor in how much you can borrow and whether you’ll be approved. Each lender has its own criteria for approval. They will look at your:
Employment type and status
Your employment status and type of income can add to the complexity of applying for a mortgage. For example, if you’re self-employed or you make most of your income through discretionary bonuses, lenders may be more cautious about the deals they offer you.
Certain professionals, such as doctors and lawyers, can often gain access to higher income multiples, such as 5 times salary and even 6 times salary.
Age
Some lenders have a limit on how old you can be at the end of the mortgage term, which can be upwards of 70. That means that if you’re over 30, you may be declined for 40-year mortgages, though you could still get a mortgage for a shorter term, which would have higher monthly repayments.
Getting matched with a broker experienced in standard mortgages
As we’ve shown above, one person’s £900-a-month mortgage can be very different from another’s. The amount you have to spend monthly is only a small part of the picture lenders look at. Your deposit size, credit history, income, and employment status are all important too, as these can indirectly affect your maximum borrowing.
So, it’s smart to work with a broker who has experience finding the exact type of mortgage you need (whether that’s a small deposit mortgage, a bad credit mortgage, a self-employed mortgage, or anything else).
