hugo, I just looked at your active-listing link. I was last through Georgetown (leisurely tour) in August 2010 and noticed that NOT EVERY “largish” +/- 130 year-old “row house” there is “tricked out” like this one. They are in varying stages of improvement. You are looking here at a property that one or more previous owners obtained permits to bring up to code and also rehabbed the entire interior to its “period magnificence.”
I haven’t checked any active listings there, but am curious as to what they would cost if purchased as a “heavy fixer?” Most have no “land” to speak of so we are talking here about an (extremely conveniently-located) “condo” (but sans the HOA).
edit: the listing’s basement appears to NOT be included in the total sq footage. Not sure how that space is calculated there (whether in finished or unfinished state).
