The assistance program requires applicants to have an SSN and Tax payer ID already. It also requires a proof of income in order to qualify for the up to $150,000 down payment. So, this isn’t for your typical undocumented immigrant.
That said, I tell you there’s an even more nefarious use case for this: Mexican Cartel Members.
They, Cartel Members, already like to have homes across the border here in San Diego either as a place to hide away or as a weekend home. This new law will in fact make that process even easier for them.
