I have found this topic interesting because I retired from shooting RE and architecture. From my experience, the subject property more or less demands how you are going to shoot it. HDR, strobe(s), shims, or a mix (flambient). Also, what you are being paid for the amount of time and effort you require to do the job. I don't like blown-out windows that are prevalent on architectural shoots but sometimes they are appropriate even on RE shoots. You are telling a story of a home and you are to convey a feeling that will attract someone to wish to preview it in person. Images are a hook and nothing more. The reason houses with excellent photographs sell quicker is because they often get more personal viewings. The key image, in my opinion, is the elevation image. The front of the house. Buyers often drive neighborhoods looking – they can't see inside but how the house looks from the outside often attracts them. The same applies to someone seeing a flyer, MLS image, facebook image or, newspaper image. That's about a 3 second hook to get them to look further. Some people shoot the interior to make it look huge. I have found that 18mm to 35mm works great. I usually shot a room using two points and always attempted to show a window (not blown). Sometimes a single point image works well. I seldom shot a room without having all the lights on. I have moved lightbulbs around when they messed up the white balance. I used mostly bounce flash because it worked well for me in most instances. I used f/7.1, ISO 320 and a shutter speed that varied greatly depending on the ambient light (1/30 to 1/200) and manual mode. If I had an entire shoot HDR I would use Aperture priority and 3 shots on 2 steps. I mostly did that for play and so I wouldn't be in a rut.Don't get set on "one-way-is-right". You may have to use all the techniques on a shoot so learn them all. I only shot swimming pools off-hand. I used a good carbon tripod and a geared Manfroto head. I used tilt-shift often but mostly a Nikon 14-24 f/2.8. Elevations I would often use a 24mm tilt-shift or a Nikon 24-70 f/2.8. I have used pole mounted cameras and I often had a tripod mounted on a hard surfaced deck mounted on my truck bed. That would give me 7' to 9' elevation.
