The Take5 deal, aimed at first-time buyers, will be available at various Taylor Wimpey developments across wider East Anglia.
The deals, which are available through intermediaries only, include a two-year fix at 5.99%, a three-year fix at 6.39% and a five-year fixed rate at 6.89%.
All Take5 mortgages have an arrangement fee of £999, with a proc fee of 0.35%.
Mark Smitheringale, head of sales and marketing at Cambridge Building Society, said: “We are excited to be working alongside Taylor Wimpey.
“The general lack of support for first-time buyers is an issue which the Cambridge Building Society is now taking a closer look at. By offering 95% LTV on these selected properties, those people wanting to get on the property ladder can now do so.”
Kevin Belsham, national sales and marketing director for Taylor Wimpey, said: “We have been working hard to secure this mortgage deal which we believe will make all the difference to those who aspire to own their own home but find it difficult to save for the large deposits needed.
“This is the latest result of our continued discussions with lenders to support this initiative as part of a range of practical and workable solutions to get more first-time buyers moving.”
