Once you've done this a time or two, you'll realize the benefits of having a fairly strict policy with procedures for enforcing it.

I respect that real estate professionals and bankers will be the last on the planet to believe that a fax machine provides more security than the worlds best encryption (even though routinely there documents are sent to wrong numbers by human error) but why in 2020 are we pushing people off a mobile app onto a web viewer to read stuff?

Is this a property that would be strictly an investment property or would you be looking to occupy one of the units? 

This will largely dictate how strict your minimum screening should be. 

I'm actually going to be in a similar boat where the lender won't loan out to an LLC (strictly residential) so they suggested getting the loan in my personal name, wait until we finished Rehabbing and get a Tenant in there, Cash out Refi like normal, and THEN quit claim the deed to the LLC and let it ride.

And on the west coast if the bank actually files a foreclosure there are very STRICT rules on what a person can do with a homeowner in foreclosure..  

Our CA company routinely offers property for sale on the MLS. 

For example, "self-dealing" is strictly forbidden and can cause your IRA to be undone and you end up owning taxes and penalties.3) The people who I talked to that have the most success with SDIRAs typically do not buy property to avoid the self-dealing issues mentioned in item 2. 

If you are strictly referring to cash on cash getting better finance terms will increase that. 

It may take longer to get a contract, lenders may be more strict.
