nirvinerealtor,
I see you are suggesting the 10 year interest only loans. Wouldn't you find it rather stressful if home values declined and you knew property values had to increase to save you before your ten years was up? This is a time bomb loan with a longer fuse. I suggest you read this post:
Financially Conservative Home Financing. I am not a believer in this kind of financing because the risk it entails. People who bought at the peak of the last bubble 1990 barely got their heads above water by 2000. In 1996 , six years into the ten, they were deeply underwater. I wouldn't want to go through that. Plus, this bubble is bigger.
"Debt ratio of 57%, you will have to go stated and pay $2,500 in loan fee." Are you suggesting this borrower commit mortgage fraud? Has "going stated" become such an integral part of the financing picture that nobody sees it as either risky or fraudulent? If I am not understanding what you are suggesting, please explain further. Also, don't you think a debt ratio of 57% is crazy? Has all of California lost is collective mind? Maybe we will all be making $500K a year and then we can afford these properties.
Rent isn't going to increase at 5% a year. It did during the price rally, but that rate of increase is not sustainable. If it were, we should all buy rental properties and become landlords. If you can get consistent 5% income growth on a highly levered asset, you would become very rich, very quickly. Most landlords are happy with a stable tenant and don't raise rent much.
I agree with you that in 1996, rent and buy were about the same; however, I don't agree with your assessment that only a 20% drop is required to bring these numbers back into alignment. Factor in a conventional 30 year mortgage, and see what number you get. It is more like 50% off the peak, and about 35%-40% from where we are today on new construction. Resale product pricing is still in lala land.
I appreciate that you did not fudge the numbers much (I disagree with a few of your assumptions, but nothing major). Also, I like that you included the opportunity cost of the lost income on the downpayment. Most forget or ignore that one. Prices are just too high right now. It is a difficult sell by the numbers -- no, it is an impossible sell, but I understand your need to try. Hopefully the crash will happen quickly. Good luck to you.
