Several factors indicate the company is not that concerned about efficiency or ease of customer process: the website, a process that seemed to focus on one issue at a time instead of all issues at once, and consistently poor communications and lack of common sense from the loan analyst we were assigned.It started off very well with the initial point of contact, Austin Lornson, who did a fine job of explaining the general refinancing process, responding quickly and thoroughly to our questions.

Other most common factor: Family Size increases due to marriage or having a child.
