I assume due to the tougher rental cover tests, this will restrict the amount of equity you can release from the property?
For example if you bought a property for £120K and the rent was £600 then you can borrow £90k.
(75% LTV = £90k and 6 x £15000 = £90k (going off £15k off borrowing for every £100 rent))
But if the property experienced good capital growth over a fewyears to say £140k while the rent didn't increase then you wouldn't be able to access the equity and remortgage.
Is there any other way to release the equity, while remortgaging without having to raise the rent?
