I always like 'Real Estate'. It's a term people know and are going to search way more than 'Properties'
I think the "real estate" option is the better of the two as it more clearly states what the site is about. The term "property" may be viewed in a variety of different ways, some of which may not be related to real estate. While I feel the domains are a little on the long side, I would say I like the Real Estate variation better.
Thanks for your opinions, I have decided to go with:
http://www.AvailableCommercialRealEstate.comIt’s a simple site that I just made, I can always add to it and improve it some later when I have more time.
I agree as far as this domain being a little long, but there are not too many short domains available with a keyword like “ Commercial Real Estate “.
