Well, maybe not necessarily the very best. But, according to NPR, they’ve been very responsible. Illegal immigrants can receive home loans if they possess I-10 numbers, which the IRS gives out to undocumented workers so the government can keep track of their taxes. Since 2000, one source estimates undocumented immigrants have taken out more than a billion dollars in mortgages. Across the country, I-10 mortgages have had a delinquency rate of .5 percent—-compared to a rate of 6.4 percent for all home loans.
