Spain's been pushing measures like rent caps in certain regions, encouraging property owners to convert empty units into rentals with tax breaks, and fast-tracking public housing construction, though honestly the scale of it hasn't kept pace with how wild the market got. The thing is, even with these plans, real affordability for regular folks is still pretty rough because supply is genuinely scarce and investors have already hoarded a lot of properties. Whether it actually moves the needle depends a lot on whether they can get enough landlords to play ball and actually build housing fast enough, which... hasn't been Spain's strong suit lately.
