Purchasing a property from an LLC rather than a Realtor / Bank

[Octavia D.]

Still learning and practicing on finding deals and what to look out for, I noticed that some properties are posted by LLC's and not a realtor or bank. Since there's much info. about doing deals with realtors and banks, how do you do deals with LLC companies? Are they more flexible and easier to work with, does anyone know, do they market their property with a realtor or on their own.
