I've started adding rent information to the file, but is far from done. The plan

+the [[file:./spare-room-manchester.org][Spare Room]] listings: not great. And, at the time of writing, I've not taken
+into account the Income Tax with the Spare Room figures. Granted the difference
+won't be that different because the annual earnings are too low, for the most
+part (falling out of the Basic Rate band).
