Nationwide improves its fixed rate £300,000+ mortgages again so they start from 4.29%

Nationwide for Intermediaries has made an unusual move by undercutting itself with its latest rate changes, as the building society was already topping many of the best-buy tables.

The lender has the most competitively priced two-year home mover fixed rates on the market at 4.29% and the lowest five-year fix at just below 4.35%, both for mortgages between £300,000 and £5 million. These rates include a £1,499 arrangement fee, and applicants need to have a 40% deposit to qualify.  If you are on the hunt for a larger mortgage, then these rates will be hard to beat, whether it’s through the deals offered to existing customers or private banks.

Aaron Strutt, product director at Trinity Financial, says: "Nationwide was already offering many of the most competitively priced fixes, and it is clearly looking to cement its place at the top of the best buy tables to make sure it is one of the first lenders borrowers look at when they want a cheap mortgage. It is good to see the price cuts still coming through. 

"This shows how keen Nationwide is to attract more customers and issue more mortgages at a time when many banks and building societies would prefer the property market to be a bit busier."

If you are on the hunt for a mortgage, there are some good deals to choose from, as well as some generous income stretches of between five and 6.5 times single or joint salaries. Nationwide’s fixed rates start from just below 4.75% for first-time buyers with a 10% deposit, which is pretty reasonable.  

Representative example: A capital and interest Nationwide mortgage of £400,000 payable over 30 years, initially on a fixed rate basis at 4.29% for two years and then on the lender's standard variable rate, currently 6.49% for the remaining 23 years, would require 24 monthly repayments of £1,984.62 followed by 336 payments of £2,506.48. The total amount repayable would be £889,808.16 made up of the loan amount, plus interest (£488,293.04) and £0 (product fee), £0 (final repayment charge), £15 (completion fee). The overall cost for comparison is 6.3% APRC representative.
