How much does a £750,000 mortgage cost?
Tags: First-time buyers, Residential mortgages
Quick Summary
Many of the lenders have improved their rates in recent weeks, but they may well start to rise again soon as mortgage funding costs have risen. The monthly mortgage repayments on a £750,000 interest-only mortgage priced at 4.48% fixed for two years would be approximately £2,800, increasing to £3,791.23 on a full capital repayment mortgage over a 30-year term. Applicants typically need a 40% deposit to access the lowest rates, like this 4.48% deal, but the rates are not much higher with a 25% or 20% deposit. Our mortgage experts can confirm how much you would need to pay depending on your income, budget and overall financial position. The lowest mortgage rate is still a two-year tracker at 3.99%, and the monthly costs on a £750,000 mortgage would be £2,493.75 on interest-only and £3,576.29 with capital repayment.

How much does a £750k mortgage cost?
Trinity Financial has access to a wide range of banks and building societies offering competitively priced £750,000 fixed- and tracker-rate mortgages.
Nationwide for Intermediaries offers a leading 4.48% fixed rate for two years, available to borrowers with a 40% deposit. This mortgage has a £1,499 arrangement fee.
The monthly mortgage repayments on this £750,000 interest-only mortgage would be approximately £2,800, increasing to £3,791.23 on a full capital repayment mortgage over a 30-year term. Rates are not much more expensive if you have a smaller deposit.
The mortgage reverts to the lender's current standard variable rate of 6.49% unless borrowers remortgage to another provider or do a "product transfer". The overall cost for comparison is 6.4% APRC.
Some lenders offer more generous mortgage income multiples, potentially up to 5.5 or even six times single and joint incomes. They also offer interest-only, part interest-only, or full capital repayment options to borrowers.
Nationwide's Helping Hand mortgage offers a 6 times salary income multiple
With a Helping Hand mortgage from Nationwide, you might be able to borrow more towards your first home. The building society offers first-time buyers specific two, five—and ten-year fixed rates and up to 6 times salary mortgages.
The minimum income requirement has just decreased to £30,000 for sole applicants and £50,000 for joint applicants. All income sources (except self-employed income) can be included.
Other lenders also offer up to 5.5 times salary mortgages to professionals like doctors, dentists, and lawyers. Higher earners can also access 5.5 times or even 6.5 times their salary, provided they have a clear credit history. Halifax has a first-time buyer scheme designed to offer more generous loan sizes to first-time buyers.
Coventry Building Society has significantly increased the amount some first-time buyers can borrow, with eligible applicants now potentially able to secure a mortgage of up to 6.5 times their income. Applicants need a minimum income of £30,000 for a sole application or a combined £50,000 for a joint application. As with all mortgages, the maximum amount available depends on the lender's detailed affordability assessment, credit scoring, financial commitments, and wider lending criteria.
How much is a £750,000 mortgage if you have a 25% deposit?
Santander for Intermediaries offers a 4.58% fixed rate until 02 December 2028 to borrowers looking for a £750,000+ mortgage. The lender requires a 25% deposit, and the arrangement fee is £1,499.
If you wanted to borrow £750,000 over a 30-year term on full capital repayment at the 4.58% rate, the monthly mortgage repayments would cost £3,835.87 or £2,862.50 a month on interest-only. This is over a 30-year term.
The mortgage reverts to the lender's current standard variable rate unless the borrower remortgages. The overall cost for comparison is 6.2% APRC.
Santander is one of the lenders selected to offer some of the most generous income multiples with a good part interest and part capital repayment policy. The bank offers up to 5.5 times the salary for single and joint applicants, provided applicants earn over £100,000 with at least a 15% deposit. The bank also offers five times salary mortgages to those earning between £45,000 and £99,999, provided they have a larger deposit.
£750,000 mortgages are cheaper when you take a two-year fix, but two-year fixes are popular
Mortgage rates have fallen in recent weeks, but more changes are likely and could lead to rises soon, as the cost of funding mortgages has increased. Two-year fixes start at around 4.5%, but trackers are priced from 0.24% over the current 3.75% Bank of England base rate.
Aaron Strutt, product director at Trinity Financial, says, "There have been lots of rate changes over the last year, but some lenders have not changed their rates for around a month. Banks and building societies have been refining their affordability calculations, allowing them to offer larger loans at lower rates. It is a good time to get a mortgage, even if rates are a bit higher than before.
"If you want the lowest monthly repayments and payment security, you probably need to opt for a two-year fix or tracker. More borrowers seem to be opting for tracker rates as they need flexibility and suspect the base rate will come down once the war ends. The three- and five-year fixes are still fairly priced and popular."
