The best rate is going to be found by your Realtor. Everyday I have calls and emails from good experienced loan origination officers. You may find out about rates on the web, but you will not find all the cost untll you talk to a reputable mortgage person. I (Kevin Duffy ReMax Realtor) have been a fulltime Realtor since 1987. Send me an email to find the best lender and rate. For a benchmark, if you have excellent credit try, Third Federal. The average 5/1 adjustable rate mortgage fell to 6.55 percent. This is something I may consider this year.
