He owned property in San Jose but in DC he rented for 3+ years.

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?

I think I can open another personal checking account at the bank I already have and it'll be under my name but i'm trying to buy out of state rentals with an LLC I own.

That's even harder to answer.Ah heck, I'll just check with ChaptGP AI which apparently owns the future, but doesn't own a property.

I would guess many government workers are renters like law enforcement and state department as they rotate in and out of the field offices to DC.

In every building, that we bought that had common heat and hot water, we seperated those units on to their own devices. 

Part of the motivation for congress writing Dodd Frank was to clamp down on the investors offering preditory terms re  rent to own and seller financing and that view has carried into craigslist rent to own adds and you say zillow. 

Would you have any helpful tips on what I need to learn, know, expect in doing this in a new state.

Owning the duplex has certainly taught me a lot over the past few years.
