However, I don't want to put in an offer until I at least see a video of it. 

And my wife does a lot of YouTube videos and has used a tool that picks her cover photo.

It's easy to obtain, costs very little, and doesn't require additional, on-going effort to maintain.Whatever cookies or algorithm is on my computer and phone, every time I open up social media or watch a  YouTube video, Anderson Business Advisors pops up.

When I first started out I thought I could figure it out watching how-to videos online, reading books, asking questions in forums, etc.

Of course, we recommend that videos be used to document all this so you can review remotely.

I took extensive video and pictures when i moved as the house was not, to most people in move in condition, obviously cleaned but very cheap and very old carpet, large areas of rooms that weren't entirely painted weird hardware sticking out of walls, screw holes or remaining screws and nails, several patched but not painted areas, tons of areas with drawing, water, oil marks on the walls (from a centimeter to 1 foot) etc etc! 

P.S. when I enter a rental suspected to be abandoned, I will record it on video.

I'm just surprised that in the dozens of youtube videos I watched re installing LVP over a wooden subfloor (and the 3 contractors I consulted, and the many home improvement forums I sought advice on :-), no one really mentioned using a 1/4" (or better) plywood underlayment, but since I've brought up my issues here on BP I've seen many folks mention that they ALWAYS do that by default. 

I saw videos all over youtube on diy hardwood projects.

You can buy a new one brand name for around 300-700 dollars, depending on brand, and get it installed for $200, or do it yourself with some basic skills and youtube video.
