Why wouldn't you spend a million bucks on a PPOR, it's the median price these days.
Pros:
Nice and clean, no maintenance or building issues to take care of.
Easy living, convenient living.
Cons:
Not much if any outdoor private areas, can't modify like a house and can't do much to add value or personalise the exterior.
Likely noise issues, of all sorts, from neighbor, (biggest issue IMO)
Not much free space if you want to do a hobby or something that needs a bit of space.
