Currently, I'm in the 90% who do not own any parks... but I'm trying to change that, dadgummit... :) lol My goal is to own 250+ doors, in at least 5 different parks, by 12/31/2021.
In April, I took the online MHU Bootcamp. I think it was worth my investment, though I have not implemented / purchased a park, yet.
I like being able to re-watch the videos after the weekend, and have reviewed various parts several times. So much information is provided in a short time, especially for those of us with no real estate / MHP background... "CAP Rate?!". I'm thankful I am able to go back and review the information as needed.
They also provided MP3 audio files from some podcast series that Frank and Dave did. I'm fuzzy on the details, but I think some of the information is now out of date since the recordings were made. IIRC, it had something to do with financing / selling homes, and probably related to SAFE/Dodd-Frank rules... I think the podcast had been recorded prior to that law. They did cover the law in the online / video course, so pay attention to the videos, rather than the audios, on that specific subject. That topic aside, the audio recordings provide lots of "real life" history, wisdom, and funny stories from Frank & Dave's life in the industry.
There are several hundred pages of documents in an e-book format, several spreadsheets, and other forms. These provide a wealth of info to help get an operator operating operationally in a quick manner. The only thing I think I would do differently is to possibly provide a printed form of the documents...
Don't misunderstand. I love the portability of e-books. However, I also like having a printed document at hand, which I pencil notes on, highlight, and add colored tape flags to for quick reference... but maybe that's just me. There are so many pages, I don't think "printing and stapling" the pages myself would work well. I think the spiral bound version would be better.
They have a forum, which has some good info, and Frank is active there in addition to his contributions here on BP. The forums are helpful.
Personally though, I think the MHU class was a better fit to help me get started and excited about the industry, rather than only reading a forum.
