I think this is a pretty bizarre/pathetic topic to be honest.
I have a variety of clients, many of whom are Asian. Here is what I deduce…
Are Asians more bullish? No. In fact all of my clients who are Asians realized the market conditions and identified they were buying for personal reasons, not because they thought the market had bottomed.
Are Asians better qualified? Of all the Asian clients I have had, I think less then 5 of them needed to go FHA. Most of them had strong downpayments. Most of them had strong incomes, the majority of them dual incomes.
Are Asians idiots for buying? Not if they are buying for the right reasons.
In general there is not any difference between the race of any buyer. The original poster is probably seeing more Asian buyers because the buyers pool has weeded out the idiots who were not fiscally responsible enough over the last decade to save money, and work hard. So what you have left in the buyers pool are p responsible people who were not boneheads. Go figure, many of them are Asian.
