I know that frustration. I see something that fits what you describe at 228 E. 13th. I don't have a way to show it to you here, but I could email it to you if you want to send me your email to my email address in the signature. There are many other properties that might be right for you in the agent database as well. I'd really suggest you use a skilled, experienced agent, as the database we use allows us to save and annotate properties. We organize your search for you, negotiate on your behalf, and take you through all the steps of buying. You won't have to worry again about misplacing a listing and you will have a professional working on your behalf.
Also, as Jennifer describes, you can search the agent database through what's called a VOW (Virtual Agent website). Most of us have had them for some time. Mine is in the signature below.
