D.C. recorder of deeds

[Jon Sheffield]

I'll try to ask this questions the best way I can to be clear because this is new to me, I've heard of people doing this elsewhere. I am currently getting list's from list source I am trying to try something different and actually go to the governmental agency in D.C. that deals with providing real estate data which I believe is the D.C. recorder of deeds. Has anyone conducted research down there? If so what are some pointers?
