But they won't! It is very difficult to get those people to post more than a low res picture of one room online when they can very easily walk through the house with a video camera, for example. Even large apartment complexes have 1-2 pictures on their website and call it a day.
The single most important thing, for me, is a nice and correct 2D floor plan. Add to that 5-10 well chosen photos and you're done on the visual front as far as I'm concerned. If you haven't convinced to at least go look at the house with that, no video or interactive 3D model is going to change my mind.
The big problem is that the overlap between the information I consider important and the information the real estate agent is eager to share don't overlap all the much
I have chatted with one of the agents about how do they work, and no surprise - they lend out everything by phone, because "uploading pictures to website takes 24 hours."
I'm a Russian living in the UK and it still surprises me that what Russians consider to be a viable information about property (gross internal and net internal area, kitchen area and a floor plan) is so rarely present on the UK property sites. "Lovely 2-bedroom" is all you normally expect.
