How difficult is it to obtain CONSENT TO LET from NRAM? Originally a mortgage express customer?

what will they ask for when they speak to me? I am bricking it as ive heard it is quite difficult to obtain consent from them. I am aware the fee is £1250 for 12 months.

Someone please assure me it wont be difficult as i have a meeting with them on friday.
My salary is less then when i intially took out the mortgage 7 years ago. Will this affect my consent to let eligibility?

Thank you in advance
