I would watch more of it but I don't want to spend 9 minutes on a video
I've seen some of the same "leftovers" when looking at houses to buy.
Having found a decent (and inexpensive) place to rent here, I know how difficult it is - but it is quite possible if one looks long enough (and takes advantage of nice places with poor advertising or poor pictures).
I completely support
regulating rental housing- the profit margins on rental housing are high enough that cutting into them isn't going to harm landlords.
Besides seeing tons of garbage, electrical, fire, and structural issues, I was particularly "thrilled" with the place I saw in a rather nice area of town... that had the stairwell's window pane completely missing and pigeon excrement all over the sill. Lovely.
