Housing Crisis
(lemmy.world)
Based on currently available numbers, there are about 31 vacant housing units for every homeless person in the U.S.
That's not what this is saying.
This says there's ~650K homeless, let's round up to a million.
Round the post number up to 30, and we get 30 Million empty houses.
This says 15 million in 2022, so the post isn't off by much, given were talking different years.
That said, the second link I posted says 15M homes is ~ 10% of the US housing inventory, and of that 10%, only ~0.7% was homeowner inventory, which means the rest is rentals.
So there's your answer: Landlords.
(Also, homeless people usually don't have the income to afford a rental, let alone buy a house, so they don't affect the demand curve, which is your second answer: Landlords don't give a fuck about the homeless)
