2nd residential mortgage

Hi all,

Just after a little bit of advice. Currently own a property on a joint mortgage with my husband. We are both on mortgage and deeds. We have rented this property out (with consent to let!) and are looking to buy a second property with 2nd residential mortgage.

My question is, I am about to start a new job and I am worried this may effect obtaining mortgage, could my husband apply for 2nd mortgage alone?

Thanks
