I will be renting ADU fulltime and will not use for personal usage.

They may get paid on the 3rd and need to not initiate a payment until their paycheck hits their account to avoid being overdrawn.I personally have a 5 day grace period and rent is considered paid when the transfer is initiated.

I spent about a year there and I had an overall good experience.Most KW offices hold weekly in-person training hosted by various experienced professionals.

I ran into these gugys personally coming out of the GFC were money was really tough to raise..

BTW: most owners that have hired a PMC, don't want to speak with you, much less meet with you in person to hear a hyped-up sales pitch.Also, you want to do rental arbitrage - so, you will need to be properly licensed to manage properties you do not own as required by your state & local laws.- why would an owner want to do business with someone NOT properly licensed?

Even if the owner seems like a really nice person, they will micromanage the builder and not like the specs of the house the builder needs to do, and/or the timing in which the builder gets it done, etc. 

can anyone you know in person vouch for this lender? 

There are multiple potential strategies it's just really going to depend on your personal situation. 

They might be willing to give different terms especially to a high net worth person that they can likely make money on cross selling.

Recently had a conversation with an MLO who had their license with Company A (NMLS regulated) and then on the side, this person conducted commercial-only business loan-related activity by starting their own LLC (company B) in the states where no mortgage licenses are required.
