However, if you are a single member LLC, then there are no partners to argue with for operations and dissolution, so I'd honestly say that the operating agreement essentially allows you to conduct business for the LLC and open a bank account and that's about it because you aren't really accountable to anybody else.  

I'll be both filing and conducting my business in NC only for the time being.

I sat down with the owner of the property, and he gave me a survey that he had conducted on the property.

@Thomas Nguyen In my own opinion if you do not know how to conduct a negotiation for a property, its time to step back and increase your knowledge so you don't end up with a pig that is going to bankrupt you.A quick search will give you loads of information on negotiation with sellers. 

A company can engage in business in a domestic state without having to undergo qualification.A foreign LLC or corporation may have to qualify to conduct business in another state if its business transactions meet certain requirements.

Once the unit has passed inspection then a survey is conducted to ensure you are requesting reasonable rent.

Any lender must be able to trust you, they rely on your management skills to conduct business, if you fail at that they have a potential loss.How do  you gain trust and confidence in others about your ability?

That goes for any new construction deals as well.It sounds like you're a bit adverse to conducting illegal activities, so that is a good thing, if you want to deal in real estate facilitating transactions, get a licensee, you can do that part time too.

It raises a red flag in terms of where in the market cycle you are if the sellers think they can charge you a fee to conduct due diligence.  

Let them know that they are not the procuring cause for the acquisition property and that they have conducted no real estate activities in regards to that particular property.
