I claim no expertise or even a strong opinion on this subject but you previously said that demand would make gold/silver continue to rise due to limited supply.
Should that not be true as well for premium properties close to major metropolitan hubs?
Although investors need to avoid properties that are currently overpriced, I think generally real estate in good locations will continue to increase in value in metropolitan areas that have reasonably strong population growth in the years ahead. As you mentioned, this is because of growing demand combined with a very limited supply of properties in good locations.
