In this guide, we’ll tell you how much you can borrow for a £600 – £700 per month mortgage and how to boost your chances of getting approved.

What mortgage can you get for £600 – £700 per month?

The amount you’ll be able to borrow will vary depending on your specific circumstances, but based on an average interest rate of 4.5% and a standard term length of 25 years, you should be able to borrow between £107,946 and £125,937.

However, your maximum borrowing is based on a multiple of your income—typically 4.5 times your annual salary—rather than a set amount you’ve budgeted for monthly mortgage payments.

The following tables show your borrowing potential based on these monthly repayments.

Calculate your maximum borrowing

It’s important to note that your maximum borrowing limit won’t be based on how much you have available for monthly repayments. Rather, lenders will base their borrowing decisions on a multiple of your income. Most will let you borrow between 4-4.5 times your annual salary, but some can go higher – even as high as 6 times your income in certain circumstances.

The calculator below will tell you roughly how much you’ll be able to borrow if you want to keep your monthly payments between £600 and £700.

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.

What factors affect whether you’ll pay this amount?

Affordability is calculated based on an assessment of your income and outgoings. Still, the two main factors determining whether your mortgage payments are kept within budget are the interest rate and the term length.

Interest rate

As the tables at the start of the article showed, lower interest rates result in lower monthly repayments. For a £700 per month mortgage, you can borrow over £17,000 more for the budget if you secure a rate of 4.5% instead of 6%.

The size of your deposit will be crucial here. The more money you can put down, the lower the rate you’ll likely be offered, as lenders will consider you a less risky borrower.

However, it’s not all about deposit size. Meeting certain eligibility criteria will also enhance your chances of securing a competitive rate. For example, lenders will look at how much you earn, your credit history, age, employment status and the type of property you’re buying.

Term length

Opting for a longer mortgage term is another way to decrease your monthly repayments.

The standard term length in the UK is 25 years. However, depending on your circumstances, lenders may offer you a longer term of 30, 35 or even 40 years. Remember, the longer the term, the more you’ll pay overall, as you’ll be making interest and capital payments for a longer period.

The table below shows how term length can impact how much you pay each month. For this illustration, assume you’re borrowing £130,000 at 4.5%. As you can see, it’s not until you extend the term to 30 years that this mortgage becomes affordable for the £600 – £700 monthly budget.

Term length (years) Interest rate (%) Monthly repayments
20 4.5% £822
25 4.5% £723
30 4.5% £659
35 4.5% £615
40 4.5% £584

For both these tables, we assume the interest rate stays the same for the full length of the mortgage. However, interest rates can change if you decide to remortgage to a different rate or move from a fixed or discounted deal to the lender’s standard variable rate (SVR).

How a broker can help with a £600 – £700 budget

When applying for a mortgage, it’s always a good idea to seek advice from a broker who can help you find the best deal and guide you through the application process. However, a broker is essential if you’re on a fixed budget and want to ensure you’re not paying more than £700 a month.

They can:

  • Share tips on improving your application so lenders are more likely to offer you lower interest rates and agree on the term length you need, making your budget go further.
  • Scour the whole of the lending market to present you with a lender more willing to offer 5 or 6 times a salary.
  • They will negotiate a deal on your behalf, utilising their expert knowledge and experience in getting similar mortgages for other buyers.
  • Find you a lender who offers high-income multiples and accepts 100% of any supplemental income you might have

Several brokers, we work with specialise in securing these types of deals. They can review your finances, suggest the type of product that will best suit you, and match you with the right lender, saving you both time and, more importantly, money.

They also have access to exclusive deals and can negotiate with lenders on your behalf. Contact us today, and we’ll match you with an expert broker from our extensive network.

We're so confident in our service, we guarantee it.

We know it's important for you to have complete confidence in our service, and trust that you're getting the best chance of mortgage approval at the best available rate. We guarantee to get your mortgage approved where others can't - or we'll give you £100*

Options if you can’t make this budget work

If you want your repayments to be £700 a month, you can opt for either a capital repayment mortgage or an interest-only mortgage.

Interest-only mortgages are a good way to keep your monthly repayments down because you only pay back the interest on the loan each month. You then repay the original amount borrowed as a lump sum at the end of your mortgage term. With capital repayment mortgages, your monthly payments go towards paying back the interest and some of the initial loan.

While an interest-only loan may seem appealing, it can be high risk because you’ll eventually have to pay off the original loan amount using a bespoke repayment vehicle. If you can’t, you may have to sell your property and other assets if they are in negative equity (i.e., if the property sale is not enough to cover the loan).

Connect with an expert broker who can help with your monthly budget

With a maximum of £700 a month to put towards your mortgage, you should seek help from an experienced broker who specialises in this sort of situation and who can match you to the right lender for your circumstances.
