Does it need to be notarized with both of us present?

I'm closing on a house in Kansas, USA.I need to get the closing documents notarized, and it must be a US notary.

If not, are there times that they will use their developments as assets or is everything always sold whenever it comes down to it?

So, yeah, it's a smart approach and if the numbers are favorable and you have Plan B in place you can do this successfully.You would need to record a notarized memorandum of the option with the county to protect your position in the deal. 

I talked to the LLC attorney and he said they provide the following 3 documents to prove I'm the 100% sole owner:1. resignation of organizer (legal letterhead)2. operating agreement3. certificate of incumbency (notarized)

I'd make sure the sales agreement is clear, notarized, go through a title company, etc., but I could see a judge either feel like I'm trying to get one over on him, or just not understand the idea of a non traditional sale. 

you cant record sales agreements etc in most markets i work unless they are notarized by the seller.. 

@Bjorn AhlbladYes the deposits and what not are at the front of my mind.  

Did you have your option agreement notarized and recorded?  

Agreed on paper and notarized.
