Do 30-year mortgages make the other houses more expensive somehow? It sounds like you got a good deal and any change would be worse than the good deal you got. I'd appreciate it if I was you.
Edit: unless you mean that the downside of 30-year mortgages is you hardly get to pay off the principal in the first several years and don't build much equity maybe? That's more a "long mortgages" thing.
