Couple questions back at you.
Are you asking about the legal aspects, as David started to address, or, are you asking about the process? Unlike David, I think it varies more, as a purchase usually has a more stringent timeline; with a refinance we get to pick the title company so have more control over quality of work received; with a purchase there are usually at least two realtors involved, and their idiosyncrasies; fewer people to keep updated with a refinance; purchase borrowers may or may not have ever gone through the home financing process before, so may take more time to educate (which can be quite fun); first-time homebuyers bring a whole new sense of wonder and appreciation when the job is done well; etc., etc. Each of these could be discussed in more depth, but...
The other question is: You seem to ask quite a few of these questions. As I sit here on a Saturday morning, working on loans and my borrowers' needs, being a businessperson I have to consider the best use of my time. I don't mind answering "real" borrower questions, as I believe that is the purpose of this site, but I am less sure about why I should spend my time answering made-up questions...Am I helping you prepare an article, for which I might get partial credit? Do I get "bonus points" and better exposure on Trulia? Please help me, and others, understand why you ask so many questions and of what value they are to us and the general public.
