Absolutely. A fade_distance of about a room depth, with fade_power 2, used
in room lights is probably what I'd do if the houses are near enough to see
anything of the yards and interiors. Ambient windows are good for farther
away. A decision that is totally dependant on the amount of detail you want
or what the scene requires.

Radiosity, as Rafal alluded too, might be good with ambient (and diffuse)
windows at some inbetween level but I'm not sure of how that might be, alone
without lights that is. To get the illumination inside and outside that way
might mean overly bright window panes being needed. Maybe opaque, maybe
transparent too. At least some time involved in adjusting the scene setup.
