I hadn't thought of it that way but yes, your spot on.

I am aware that I have blind spots and I can only talk from who and what I know, so don't take it as gospel.

You're spot on, it is so overlooked and misunderstood!

While there is still a lot of opportunity here @Mitch Davidsons post is spot on with regards to inventory, help, and saturation. 

Good stuff - you are pretty spot on - technically people max out under conventional loans at 10 - but oftentimes its with fewer properties as people run into hurdles before hitting 10, some of which you mention - wanting to diversify strategies, multifamilies, needing LLCs etc.I think you are on the right track for DSCR Loans - I always say that DSCR is really perfect for people in the 5-50 property range - typically conventional is the best fit with your first few, and then when ready to make the "jump" to scaling bigger and faster - DSCR is the best bet.

I applied for a spot in a mobile home park and was rejected.

All of the stuff he shares is already out there for free but usually when you pay for some sort of course, academy, seminar, etc...it's more about that information being all in one spot, organized, access to mentors, etc.  

I would guess LTR unless you have a really prime spot. 

But if he did, I would pay him on the spot when they were delivered.

Spot on!
