I have not heard of any "tours" like we experienced a year or so ago. Depending on your needs, any Realtor can set up a search of the local MLS that searces for homes that meet your specific needs in terms of price, location, size etc. (even foreclosures). It can be very specific. More so than any search website out there.
You'll receive an email notifying you that a home that matches your needs has been put on the market. This is a much more effective way to find a home. It will save you a lot of time because it will only show homes that meet your needs. If you would like some help with this, please let me know.
