Residential and BTL mortgage in parallel

Hi all,

I am curious to ask how likely is it to do both at the same time? It sounds logical that it is possible but has anyone done it?

So basically a friend of mine is seeking some help on the likelihood of completing both given the stamp duty holiday period.

So he is a first time buyer and also want to do a BTL. are you able to start both process and finish before the stamp duty holiday?

How long is a piece of string?
