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 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 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.
