The mortgages are available with lending at up to 95% LTV and are all fee-free.
Hinckley & Rugby Building Society has cut the interest rates on three mortgages particularly attractive to first-time buyers.
Their 3-year fixed mortgage sees its rate cut from 3.24% to 2.88%.
After three years there is a discount rate, currently 4.49%, for two years, but ERCs reduce from 3% in year one to 1% in year three.
A 2-year fix Joint Borrower Sole Proprietor product has its rate cut from 3.49% to 3.29%.
At the end of the fix there are three years at the discount rate (4.49%) and ERCs step down from 2% in year one to 1% in year two.
For their five-year fix Joint Borrower Sole Proprietor product, the rate has been cut from 3.89% to 3.69%.
ERCs decline from 5% in year one to 1% in year five.
The mortgages are available with lending at up to 95% LTV and are all fee-free.
Two of the mortgages are designed to appeal to buyers who want support from the Bank of Mum and Dad whilst the Joint Borrower Sole Proprietor products enable family support for buyers.
Carolyn Thornley-Yates, head of sales and marketing at Hinckley & Rugby, said: “Free-free mortgages at such high loan to values help first time buyers manage both their deposit and their budget as they move into their first own home.
“We have been offering Joint Borrower Sole Proprietor mortgages since 2016 to enable parents, who already own their home, to help a son or daughter.
"As we do not have a maximum age at term-end, these mortgages are now an option for all generations within families to back their buyers.”
All three mortgages feature free property assessments up to a value of £1m.
