Is it still relevant?

Video and/or take pictures of everything in case you have to pursue her in small claims.  

Tell tenant you will review the maintenance history and the video.

I do not wish to waste my time watching videos,searching the internet for how tos and what I should be doing.

It would be best if you had a timeframe in place for initial reports of uncleanliness or broken items, maybe three days, but the truth is that all complaints are relevant no matter the time.

As far as the video.

It's really great for learning the fundamentals even if you aren't investing out-of-state, and of course extra relevant if you are. 

I really can't say what my average return was because over the decades I didn't keep track, it's not a relevant measurement.

For that reason I built a full-functioning cash flow model taking into account hard money, the mortgage refinance and all relevant operating expenses to assess monthly cash flow.

I have made 30 videos on how to do things and put them on a YouTube page for our tenants, sent it out on an announcement, etc.
