If you post the link to the property you are referring to, we will be able to answer your question. Or you can post the address and a Realtor can look it up for you.
If you are looking for a place to buy in SF, I have a great Realtor that I work with. I work in the Sacramento area but I referred a client to her and she found a great home for my clients (they bought a house earlier this year). If you like, I can forward her contact information to you.
