In your zeal to prove the benefits of illegals you forget one thing: Banks are allowed to use TIN's to give out mortgages.
In case you don't know what a TIN is it is a Taxpayer Identification Number. It can be very easily gotten using a Matricula Consular card which were being passed out by the millions several years ago.
Matricula Consular are available at Mexican consulates and embassies. It’s not something that happened in the past ~ but as far as getting a mortgage is concerned, the banks still continue to insist on legally recognized identification ~ the matricula consular won’t cut it.
5 million illegals getting morttgages is buulshit
