I compared a 30-year fixed to a 5/1 ARM on the same house in Phoenix
After running the numbers on a $350,000 loan the 5/1 ARM beat the fixed rate by $200 a month and I will be out of here in 4 years anyway, so why would anyone pick the 30-year fixed if they know their timeline?
Tessa's right, life has a way of throwing off the best laid plans. The ARM is only a deal if you actually leave, otherwise that rate adjustment can really sting.
