Financial Advisers have slammed cheap "stepped" mortgages. Abbey recently introduced a product where rates start at 2.99%, then shoot up to 6.2% then 6.35% over 5 years.
There is also a £799 arrangement fee.
People might be able to afford the payment in year 1 but the the huge increases mean first time buyers face a huge payment shock. You're locked into using the product for 5 years, if you try to get out, you will face a redemption penalty
