Online videos: A good idea?

[Jonathon White]

I made a video introducing my house for a prospective resident who lives overseas (http://www.aiyouliliang.com/129w/index.htm). , introducing the area around the house, the layout of the house, and a few common house chores that they are expected to complete and how to do them (i.e. garbage, snow removal, grass cutting, keeping basement humidity correct...)

1) In the future, is it a good idea to post a video for prospective tenants and ask them to watch it first before showing?

2) What should be changed in the video to improve it?  (i.e. added, deleted, blah blah...)

Would Appreciate your advice and picking your brains as I am quite new at this!  

Thanks,

Jonathon
