Man, this story is tragic, and the videos really tell the tale. I'm so sorry about your experience. As a long-time fan of Clayton's many podcasts (not just his real estate show), I'm disappointed.
I had a call with MI last year but decided to go with a different Indy turnkey company when we made our first investment property purchase last month. The team we worked with on the sale was great and I had same-day (sometimes same-hour) responses to my emails. I drove up there from Nashville, and they spent half a day with me showing me around, answering questions, helping me get acquainted with neighborhoods, walking me through the actual property I was interested in (as well as others), and meeting their rehab crew supervisor. When the work was done, their contractor did a full walk-through with me by Facetime video to show me the completed work.
When they handed me over to the property management company, I was equally impressed with their systems and communication. The unit isn't rented yet (only been available a few weeks so far, and that was over the holidays), but I get a report every Friday like clockwork that shows me who has expressed interest, how the PM got the lead, and what action and follow-up the PM has taken to get it filled. I can't ask for more than that. Hopefully it'll get rented out once we get into the new year.
Like you, this was my first investment purchase to dip my toe in the waters. I know there's risk with C-class properties like these, but my on-site visit (before the purchase) gave me confidence to move forward. I'm sorry you've had a much different experience!
