Meta Keywords Advice

Does anyone have a suggestion of keywords for a mortgage site?
I have a blog describing the mortgage process mortgage in detail to help people better understand what they can do to get approval. I will use the obvious keywords like "mortgage, loan, equity, etc" but I know my little site has little more hope to score high in those very popular. I can use these to Meta Tags, but with other items I have for submission of electronic publications. Does anyone have any advice for me more hits on my site and articles? Thank you.
