They had loans as low as 2.5% several years ago. I had a 5 year arm on last house at 4.7 and sold it prior to the bubble bursting, at a major profit. I was also near a military base and while I would not have made as much now as I did the, I think I would have done ok. Arms work if ur going to move alot like I do. My current loan is conventional but I'll be selling within 3 years.
