This plays a significant role in freezing the value of the building. The property can't be resold at a profit. As a result, the rents won't increase from $1,000 to $2,000 or $2,500 decade after decade. If a non‑profit organization owns a building, the organization can't resell it. This keeps rent affordable.
Unfortunately, in Canada, this hasn't been done enough for many years. I'm saying this with all humility.
