TSB is bringing a high-LTV mortgage product aimed at first-time buyers to market for just one day, 11 September.

Available at 85 per cent to 90 per cent LTV on a five-year fixed rate, the product criteria demands that the funds are used for a house or bungalow only and at a maximum term of 30 years.

The maximum loan is set at £350,000 and the maximum loan to income multiple at 4.5 times income.

TSB says that applications must be submitted between 8am and 5pm. It adds that the product will be removed when maximum capacity is reached.

It also says that the criteria restrictions detailed above will apply to all applications within the 85 per cent to 90 per cent LTV band “in the foreseeable future”.
