The intermediary arm of the Yorkshire Building Society had originally planned to launch the range today.
A spokeswoman at Accord Mortgages provided the following statement: “We have taken the decision to postpone the relaunch of our 75% and 85% LTV products until Monday 20th February due to unprecedented application levels over the last week.
“We have consulted with our key lending partners and explained that we wish to maintain our service levels and they were in agreement that postponing until Monday was the preferred course of action.
“I can confirm that the uplift we have seen has included an increased interest in interest-only mortgages following moves by competitors in this area of the market.”
