The second mortgage loan fits all the requirements that require the written application. It's for the refinancing of a loan to purchase a dwelling, and the applicant will continue to use it as a primary residence.
The fact that it's a junior mortgage (until, of course, it pays off the first, at which time it rises to Alpha-dog position) has nada to do with the issue.
