Yes, "lots" = more than one
Spain is still struggling with higher demand than supply, so people end up homeless. At the same time, Spain struggles with properties in high-demand areas being empty because the owner doesn't want to rent or sell it, so no one uses it at all.
Finally, we're getting "upkeep taxes" added to those places, so they can either be utilized, or the owner "penalized" of sorts.
But up until now, there wasn't anything like that, so the alternative for many is to hole up in a empty building no one cares about, or live on the street. And obviously, many take the first choice. It's hard for me to blame them when the other choice is living on the streets.
