Of condos and houses

Yesterday I attended an open house at a new condominium just for fun. It is located on West 9th St. between Avenue U and V. This two bedroom (really a one bedroom since the second bedroom looked more like a small office) second story apartment came with every imaginable amenity including central heating and grantite countertops. It wasn't very big but it was pretty nice and better yet, the maintenance fee was a low $175. How much for the apartment? A little over $400,000. The real estate agent also represented a house a block away which was selling for over $520,000 but it needs some repairs. It is so strange to me to have a house and a condo have only $100,000 difference in between. All units except for two in this building are already sold.
