The new lender will target professional portfolio landlords and specialist property investors.
Mortgage rates start from 2.69% on a range that includes two and five-year fixed-rate products.
Zephyr accepts individual and limited company applications through a number of brokers for individual buy-to-let properties, as well as for houses in multiple occupation, multi-unit freehold blocks, new builds and flats above commercial premises.
Peter Charge, head of sales at Zephyr, said: “We’re arranging loans of up to £2m on behalf of institutional investors for our standard range and up to £1.5m for specialist properties and are assisting them with accessing funding from third parties.”
Zephyr is the first brand that financial services administrator Computershare has launched, with funding provided by institutional lenders.
The company will be responsible for creating partnerships with approved intermediary brokers, underwriting, fulfilment, and day-to-day administration.
