A £250k mortgage sits right in the middle of the UK market. The average home now costs about £273,000 (ONS, August 2026), and first time buyers pay around £230,000 on average, so a £250,000 mortgage is one of the loan sizes we arrange most often. It suits first time buyers with a 10% deposit, couples moving up from a flat, and homeowners remortgaging after their fixed rate ends.
In this guide I will cover the salary you are likely to need, how much deposit lenders want, your credit history and, most importantly, the monthly repayments on a £250,000 mortgage at different interest rates. There is a calculator part way down so you can try your own figures. If you would rather talk it through, call the Alexander Southwell team on 03300 432 428.
Lenders work out how much you can borrow using income multiples. Most will lend around 4.5 times your annual income, some go to 5 times, and a few go to 5.5 times for higher earners or certain professions. Here is the salary you would typically need for a £250,000 mortgage:
These figures can be one salary or your combined income on a joint application. Two people earning £28,000 each have combined earnings of £56,000, which at 4.5 times income is just over £250,000. So a couple on fairly average wages can often borrow this amount between them.
Income multiples are only the starting point. Every lender also runs an affordability check that looks at your monthly outgoings: other debts, car finance, credit cards, childcare, and the cost of running the home. A few hundred pounds a month on car finance can reduce what you can borrow by tens of thousands of pounds, so it is worth knowing where you stand before you start viewing. Our guide to the debt to income ratio explains how lenders weigh this up.
Lenders will also stress test the loan at a higher interest rate than the one you are applying for, to make sure you could still pay if rates rose. That is why two people on the same salary can be offered different amounts by different lenders.
This is the question most people want answered. Below are the monthly mortgage repayments on a £250,000 capital repayment mortgage over a 25, 30 and 35 year mortgage term, with the total interest you would pay over the life of the loan. The rates are examples to show how much the interest rate matters, not offers.
Every 1% on the interest rate adds roughly £140 to £160 to your monthly payments on a £250k mortgage. Average five year fixed rates went back up to around 6% in early October 2026 (Moneyfacts), although the best rates for bigger deposits and clean credit are lower than that. The rate you are offered depends mostly on your loan to value and your credit history, which is why both are worth getting right.

How you repay the loan changes your monthly repayments more than almost anything else.
With a capital repayment mortgage each payment covers the interest plus some of the loan, so the mortgage amount is cleared by the end of the term. This is what most homeowners have, and for a residential home it is usually the only option a lender will offer.
With an interest only mortgage you only pay the interest each month. On £250,000 that is about £1,042 a month at 5%, against £1,342 on repayment over 30 years. The catch is that you still owe the full £250,000 at the end. Lenders want a believable plan to repay it, such as investments, savings or selling another property, and most ask for a bigger deposit and a minimum income. Our guide to mortgage repayment types goes through the options, including part and part.
A longer term length means lower monthly payments but more interest overall. On £250,000 at 5%, stretching the term from 25 to 35 years lowers the payment by about £200 a month but adds over £91,000 in total interest. A shorter term means higher monthly repayments but you pay far less interest and own your home sooner.
A middle route is to take the longer term for breathing space and overpay when you can. Most fixed rate deals let you overpay up to 10% of the balance each year without a charge, which brings the total cost down without locking you into a higher payment.
The deposit depends on the price of the home you are buying. To borrow £250,000 you would need roughly:
Loan to value (LTV) is the mortgage amount divided by the property value. Lenders price their deals in LTV bands, usually at 95%, 90%, 85%, 75% and 60%. Crossing into a lower LTV band can cut your interest rate, so if you are just above a band, a few thousand pounds more deposit can save you a lot over the deal period. Higher deposits also give you more lenders to choose from.
Budget for stamp duty, solicitor fees, a survey, moving costs and any product fee the lender charges. At the time of writing (October 2026), first time buyers in England pay no stamp duty on the first £300,000 of a purchase up to £500,000, so most first time buyers taking a £250k mortgage pay little or none. Home movers pay stamp duty from £125,000. Some lenders let you add the product fee to the loan, but you then pay interest on it. If family are helping with the deposit, our Bank of Mum and Dad guide covers how lenders treat gifted deposits.
A clean credit history gives you the widest choice of lenders and the best rates. Before you apply, check your credit report with all three agencies, make sure you are on the electoral roll, and keep credit card balances low. Our guide on improving your credit score for a mortgage has a full checklist.
A poor credit history does not always mean a no. Missed payments, defaults or a CCJ from a few years ago can still be accepted by some lenders, though you may need a bigger deposit and the rate may be higher. As a bad credit mortgage broker we know which lenders look at each type of credit problem and how recent it can be.
Being self employed does not change how much you can borrow, but it does change how lenders work out your income. Most want two years of accounts or tax calculations, and some will use your latest year only. Company directors can sometimes use salary plus share of profits rather than just dividends, which can make a big difference to how much they can borrow.
Once you know what you can borrow, the next decision is the type of mortgage deal:
Our guides on fixed vs tracker mortgages and two or five year fixes go into more detail.
When your deal ends you move onto the lender's standard variable rate, which is usually much higher. On a £250k mortgage that could add a few hundred pounds a month, so we start looking for your next deal about six months before. If you want to leave a fixed rate early, check the early repayment charges first, as they are often 1% to 5% of the balance. Remortgages with us are always fee free.
Going direct to your bank only shows you that bank's deals. A whole of market mortgage broker compares lenders across the high street and specialist lenders, and knows which ones suit your income, deposit and credit file. That matters because the lender offering the lowest rate is not always the one that will lend you £250,000.
We can also get you an agreement in principle (AIP) early on, so you know how much lenders are willing to lend before you make an offer. Our borrowing calculator is a good place to start, and our first time buyer mortgages page explains how we help people buying their first home.
Usually between about £45,500 and £62,500 a year, on your own or combined with a partner. Most lenders lend around 4.5 times income, which works out at about £55,500.
At a 5% interest rate over 30 years it is about £1,342 a month on a capital repayment mortgage, or about £1,042 a month on interest only. Over 25 years at 5% it is about £1,461. Use the calculator above to try your own rate and term.
On a single £40,000 income it would be 6.25 times salary, which is more than nearly all lenders will go to. You would usually need a joint application, a smaller loan or a lender scheme for certain professions.
The minimum is usually 5%, which is about £13,158 if you are borrowing £250,000. A 10% deposit or more opens up more lenders and better rates.
Over 90% of our cases are fee free. Where a case is complex or involves adverse credit we may charge a fee of up to £995, and we always tell you before we start. Remortgages are always fee free.
Your home may be repossessed if you do not keep up repayments on your mortgage.
