I still think a 10 year I/O is not horrible. I don't think that they go into foreclosure with anything like the frequency of neg am loans.
There is another type of loan I saw after the debacle of the 80s neg am loans. My S & L called it a GEM. Gain every month. It started out interest only and then went up 3-5% of the previous payment amount every year. The increase paid principal only. It paid off in 12-15 years or so. Very few of those went into foreclosure. A 3% increase in payment for a year or 2 or 3 is tolerable. Usually people get raises of that amount.
Nothing like doubling the payment like the stupid option arms. If, along about the 5th year, you can't pay the increases anymore, well, you have paid the mtg down a significant amount. and presumably can refinance.
Of course, if you expect housing prices to drop another 30%, which they well may, it makes sense to wait anyway.
