evidence: Her signature housing policy calls for up to $25,000 in federal down payment assistance for first-time homebuyers who have paid their rent on time for at least two years. That dramatically expands on Biden’s prior proposal for a $10,000 tax credit for first-time buyers, which had limited additional down-payment assistance to first-generation homebuyers. [...] The Trump campaign also quickly slammed the proposal, with Republican vice presidential candidate J.D. Vance claiming "Kamala Harris wants to give $25,000 to illegal aliens to buy American homes." It is unclear whether the Harris plan would have a citizenship requirement, but immigrants present in the country unlawfully are not eligible to apply for traditional, or "conforming," mortgages. Depending on how the program was administered, that could also make them ineligible for federal assistance with a down payment.
