Interest rates on both fixed and tracker mortgages have dropped to their lowest levels for 23 years when rates were first recorded.
The average two-year fixed rate mortgage is now 4.32%, while the average three-year deal is 4.82%, according to data provider moneyfacts.co.uk.
The fall has been caused by rising competition between lenders, driving them to lower their prices to attract new customers.
With the Bank of England base rate at an historic low (0.5%) for 27 consecutive months, lenders have also found it cheaper to lower rates.
No interest rate rise
This news contradicts results from earlier this year when mortgage rates began to rise due to fears that the base rate would be increased.
But the surprising fall in inflation in April was enough to delay a rate rise and experts now believe the base rate will not start to rise until next year and lenders should continue to keep their prices low until then.
The research is positive for homeowners who are being battered by rising household bills and there is also good news for first-time buyers as the price of deals with the smallest deposits have also started to fall.
Michelle Slade, spokesperson for moneyfacts.co.uk, says: "Lenders appear to be applying cuts equally across all loan-to-value (LTV) tiers, which is good news for first-time buyers, as previously cuts were only being applied to the lower LTV bands."
Slade also says while rates could still fall further, it’s more likely lenders will improve their current deals for borrowers with smaller deposits.
But she warns as base rates will inevitable begin to rise again, "If borrowers delay too long to secure a new mortgage deal, they could find that they miss out on some of the lowest rates ever seen."
