How much does a £3 million mortgage cost?

There is competition between private banks and high-street lenders to attract high-net-worth clients as the cost of funding mortgages reduces despite the Bank of England base rate staying the same. 

Suppose you want to raise £3 million to purchase or remortgage a property on an interest-only, part interest-only or full capital repayment basis. Trinity Financial's brokers can access a lender offering a two-year fix at 4.44%, and the overall cost for comparison is 7.7% APRC. 

The monthly payments on a 4.44% interest-only mortgage would be £11,100, rising to £15,093.79 on full capital repayment over a 30-year term. The mortgage has a £1,499 arrangement fee, and you need to put down a 40% deposit to qualify. After the fixed rate, borrowers revert to the 8.24% standard variable rate unless they switch products.

This product is available for mortgages up to £5 million, and rates are not much more expensive if you have a smaller deposit. Most of the £3 million+ larger mortgage loan rates start with a four or a five, although since the start of 2024, they have been getting cheaper.

 

What about £3 million five-year fixed rate mortgages?

NatWest for Intermediaries offers some of the most competitively priced larger loan five-year fixes. 

Aaron Strutt, product director at Trinity Financial, says: "If you prefer a longer-term fixed rate option to borrow £3 million, our brokers have access to a 3.94% five-year fix through our large loan contacts at NatWest for Intermediaries. The monthly repayments on a £3 million mortgage would be £9,850 on interest-only or £14,218.88 on capital repayment over a 30-year term."

This mortgage has a £1,499 arrangement fee, and borrowers must put down a 40% deposit. The standard variable rate is 8.24%, and the overall cost for comparison is 6.6% APRC.

 

What types of £3 million+ mortgages are borrowers taking?

More of our clients are taking two-year fixes rather than five-year fixes because they expect mortgages will come down over the shorter term.

Five and ten-year fixes are often cheaper than two-year fixes, although the gap has closed compared to this time last year. 

Private banks have been improving their rates over the last month, and they are significantly lower than they were.

 

What is the most generous mortgage income multiple for a £3 million mortgage?

Banks and building societies offer mortgages up to 5.5 times single or joint salaries to wealthier borrowers. While many homebuyers will not need the entire 5.5 times salary multiple, it is a valuable tool to enable us to get the mortgage loan size they require.

Income stretches help because the lenders reduce the maximum loan size if borrowers have children, cars on finance, private school fees, other residential properties or ongoing credit commitments.

Most private banks target high-net-worth clients and tend to have minimum mortgage loan sizes between £750,000 and £1 million. Some private banks require borrowers to earn at least £300,000 a year to qualify or have more than £3 million in net assets, while others have tighter rules for overseas investors.    

Lenders can vary their affordability rules for high-net-worth clients, and they can make exemptions or take charges on worldwide assets like property portfolios or investment funds.  

 

Private banks vs the high street mortgage lenders

There has been less focus on transferring assets and current accounts to private banks as part of the mortgage process. 

If you are planning to buy an expensive property and need a larger mortgage, it is often better to research the overall market and the private banks to ensure you get the best deal. With rates fluctuating so much now, if you can get a rate that's 0.75% cheaper through shopping around, it is well worth the effort. 

Some private banks are well known for issuing larger loans to borrowers with smaller deposits, while others will lend to overseas buyers using income from multiple sources.

Accessing a £3 million buy-to-let mortgage through a more standard lender is more complicated than a £3 million residential mortgage. 

More standard lenders offer £3 million+ buy-to-let mortgages, but the choice is more limited, and the rates are also high in many cases.

Private banks will offer terms on larger buy-to-let mortgages and tend to be on tracker rates.

High-street mortgage lenders have set up specialist high-net-worth departments to provide wealthier borrowers with larger mortgage loans.

The banks and building societies are consistently providing £1 million+ mortgages to borrowers purchasing properties or remortgaging.

Some of the lenders will provide mortgages up to £5 million or £10 million with £999 arrangement fees.

Interest-only mortgages are available to wealthier clients looking for larger mortgage loans. The lenders accept a range of repayment vehicles for interest-only repayments, including the sale of the mortgaged property, lump-sum overpayments from bonuses or the sale of other properties.

It is not always necessary for wealthier borrowers to use private banks to secure large mortgage loans if they can prove their income through tax returns, company accounts or payslips.

The benefit of using a high street bank or building society over a private bank often comes down to cost.

High street lenders have been taking part in a price war over the last few years and some of them have been offering their cheapest ever rates to borrowers taking £1 million+ mortgages.

The price of £3 million+ mortgage loans for borrowers with larger deposits is often priced around 4% with £999 arrangements fees.

If you are remortgaging, the lenders even provide free property valuations. 

If you are looking for a larger mortgage loan, it is important to secure the lowest rate with the most competitive arrangement fees.

As part of our service, we take the time to understand exactly what our clients require and then research the market to obtain the leading deals and the fast possible mortgage offers.

We understand the larger loan mortgage market and what it takes to get applications agreed as efficiently as possible.

It typically takes the mortgage lenders around two weeks to produce mortgage offers once they have received all of the information they require to process the application.

If the lenders asked for additional information or requesting figures from an accountant this can slow down the process.
