I think that's a narrow-minded view of looking of looking at Detroit if you not from here looking at the city if you're an outsider.
Born and raised in Detroit a lot of the population started declining around '08-09. Which left abandoned homes. You have to look at all the stuff Detroit has been through '67 roits (before my time), Devil's Night, Mayor scandal, public schools getting closed like crazy etc.,
Even with all that said there are some nice neighborhoods in the city but a SLIM few. The problem that I have with the city is that a lot of money has been put into the downtown area as far as the casinos, restaurants, & sports arenas are concerned but most of the neighborhoods still look like shyt. If you find a nice home in a good neighborhood in Detroit it's probably an abandoned house next to or across from it. Detroit has its good & bad but a lot of work still has to be done.
