Does getting the EIN signify the completion of the LLC formation?

The property becomes more valuable because the lower cap rate signifies a "less risky" investment so the value is greater.  

when putting up earnest money to get a property under contract, if is a good faith gesture signifying that you intend to buy or have/find a buyer... understood.

Why make it a partnership and have to file a 1065 unless marital issues are forcing it?

You have no deal until that contract is signed because a signed contract signifies the property is tied up with you.

IMO mis-matching appliances usually a signify a rental.  

@Dina Harleth ,That won't matter that is was only in one parents name It was marital property.

An atty informed me that the title companies will still require their signitures at all sales stating they have no marital interest.

you get a fair housing complaint because the new one is a different color, marital status, etc...
