Where can I find a 5yr fixed with a start rate between a 1 or 2 percent and with a full rate between a 6 or 7 percent?
Wow! You know what you are looking for... so first of all, congrats on doing your financial homework (you are in the minority of consumers of financial products, unfortunately).
What you are looking for is a pay option ARM. 1% - 2% percent on the Negative amortization payment is possible, but a fully indexed rate between 6% - 7% is not out there currently.
The only place that could possibly offer something like this is World Savings because they're a portfolio lender. I also know that Quicken Loans is pushing hard on Pay Option Arms these days as well.
