He uses poorly thought through methods, I've listened to his "methods",  Thus, he has the high amount of  Due On Sale called in a short period of time. 

Lessons learned is not to buy a property with a high HOA.

I would highly recommend you create an LP agreement.

I have sold in California, took the cash and moved out of state (to Indiana) and highly regretted it - I didn't have a real estate investor mindset then.

I can say in Detroit the wholesaler your talking to has most likely found that deal from 2-3 other wholesalers, they literally have to payout 2 - 3 other parties to get the deal and this is what the fees are high and the deal makes no sense.

So that area is based mainly on ease of longer term (ish) rental income, with about 2-3 years stability depending on how often people PCS and the (somewhat) quality of tenants (bc you never know, even with military).

I would highly recommend sticking to the 30 year option or not doing it at all. 

I won't just write them all here but I highly recommend contacting a qualified 1031 intermediary to walk you through the process.

Also showing almost a 20% CoC return, which in my research I've found to be a highly ideal number for investors.Is there something I could improve on with this report or fix?

If you rent in a high-crime area, I wouldn't suggest it.
