In reference to your first question:
I'm not sure of the exact number of homes for sale in Albany,NY, but if you go to my web site http://www.thomasjrealestate.com and click search the MLS. You can search the entire capital region and sort by town, price, # bedrooms and so on. If you find a home you are interested in just give me a call and I will be happy to assist you.
While at my web site http://www.thomasjrealestate.com go to community info / links, under local government click on New York State Tax Map Info and pick Albany County. Let me know if you have any problems searching this system.
