There's so much of the sh*t out there (real estate inventory) that there's not even enough people to lease, nevermind own.
Everyone's downsizing. 5-bedroom houses aren't needed for retired couples with no kids at home. Single people don't need luxury condos when they have no jobs. Nail salons are going bankrupt by the dumptruck full, along with the entire retail industry. Its a secular trend.
If the leasing market was healthy...then there wouldn't be a problem selling real estate.
