Personally I wouldn't feel comfortable trying to wholesale a relatives $1M home knowing that I am breaking the law if I cross over into doing anything that can be considered representing them in the transaction, and knowing it will only be marketed to people who buy properties wholesale (typically investors who don't want to pay retail prices), instead of the majority of retail buyers active in the market who are typcially willing to pay more. 

I personally have not heard of the website that you came across.

Are you referring to personal losses or other people had losses?

Keep in mind, you can’t use personal funds or your home's equity to directly fund the SDIRA investment, and all property expenses must be paid from the IRA.

I personally use 40% but I'm also in a higher rent area.

the only thing with that is protecting future landlords.. but then again thats a personal choice..  

Personally CA scares me. 

He's efficient and personable and is very able to assist you with questions if needed.Hope to discuss this with you further,

I personally have no connections with anyone who is involved in this niche and I'm wondering how other people have started their journey.

Not that it cant or wont, but unlikely.If OP applies for homestead on a new property, then I personally would not lie during the application about receiving the exemption on the existing property.
