evidence: Vice President Kamala Harris plans to announce Friday what her campaign is describing as a four-year plan to lower housing costs, including $25,000 in down payment assistance for first-time homeowners and actions aimed at spurring the construction of new housing, including tax incentives for building starter homes. [...] The plan promises to provide up to $25,000 in down-payment support for first-time home buyers. The down-payment support would apply to working families who have paid rent on time for two years, with more generous support for first-time home buyers. The plan, which would be implemented during Harris’ first term, according to the campaign, would also provide a $10,000 tax credit for first-time home buyers, something Biden proposed earlier this year. According to the Harris campaign, the plan would allow for over 1 million first-time buyers per year, including first-generation home buyers, to access the funds.
