>inability to re-shape the property, the lack of permanence (you can be kicked out) ... that's a good starter. Some of those are inherent to the housing like the inability to re-shape the interior much.

Those are not density problems; they're renting problems. You can rent a single family home or purchase an apartment.

Okay so I have a condo right, I bought it, it's mine. Can I add an extra room? Maybe a patio? An outbuilding?
