i recently looked at a park for sale, and I would recommend going to the park with the owner/agent and spending some time with them walking through the park, taking pictures/video, asking all your due diligence questions and speaking to tenants if they are outside and friendly.  

@Marvin McTawPlease look at the video link that I gave you in a previous postJv with the seller is better than 70% of ARV - costs because sellers make more money on the JV if it is minor Rehab

I have a ton of pictures and videos of the house I am need help on.

I've watched all kind of YouTube videos most just looking to sell you somthing eventually.

@Matt Dupee I am also new in MA, but here are my thoughts on what I am doing right now: The best way to get started is to commit to Real Estate and set some "Education goals"  1) Listen to every podcast from BP / ASK BP Video's ( I go to the gym and listen to 1.5 podcasts a day doing that)2) Become a PRO member and watch every Webinar @Brandon Turner does.  

Also Grant Cardone is a excellent guy to follow you can find plenty of his youtube videos online on the subject

They also made a video of the current condition of the unit when they entered it. 

This goes back a ways - video

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?

Just like you explain in your videos!
