Vice President Kamala Harris recently outlined an economic policy focused on affordable housing as a key element of her "opportunity economy." Her plan includes building 3 million new housing units over four years to reduce the cost of owning and renting homes. Harris proposes a new tax incentive for homebuilders targeting first-time homebuyers to incentivize this construction.  Critics argue that it could worsen the housing market by complicating supply-side initiatives. Key challenges include defining "starter homes" and managing construction costs.
