I'd go with 15 years conventional mortgage... that will probably be you lowest interest rate.
Really? Last time I got a mortgage, in 2003, I got a 5 year fixed balloon because it had a lower rate than a 15 yr fixed. And I had plans to sell in 5 years.I would agree. The other type you mention is called a balloon mortgage and is much less common, as well as generally having a higher interest rate.
