I know an Egyptian family in the Northpark Richmond American tract lost a very good tenant some years ago. They have been looking for another perfect fit tenant ever since.
I ended up renting it fairly quickly. I thought it would be more difficult, but it seems that there isn't many people looking to rent a room in the area. I listed the room on Craigslist and had a good deal of people email me, I took my time and ended up renting within a month.
I also did a poor job marketing the room. I didn't have a great picture of the home or anything just a shot of the empty room.
