Here in Maryland and in NYC especially Queens there was a huge invasion of Koreans, and the illegals did the home and business construction. Koreans open small businesses which is a good thing, but in such masses the form their own society not interacting. Their kids quickly abandon their parents Korean norms and quickly join the MTV, flash the money, no morals (bottom feed), rap type culture. They were also part of the boom but maybe not subprime. Not sure where they fit in the bust.
Actually, besides fellow, often legal Hispanic landlords exploiting their own, there was a lot of exploitation of illegals by Asian* landlords who saw a big moneymaker in renting to illegals. Being legal, their actions would not show up as loans to illegals, but the housing they provided was to illegals.
