Financing is one of the most critical parts of a real estate transaction. It is imperative that you retain the services of a highly qualified, competent and professional lender. 

If you need help finding a lender, I can put you in touch with several highly skilled professionals.

Ideally, you should find a lender and get "pre-qualified" for a mortgage before you ever start looking for a house. Not only will you feel more confident knowing that you'll have a certain amount of money (which can also narrow down your price range for potential houses), but you'll be a more serious candidate to sellers.
