This isn't the type of deal you want a rookie working on.They are an amazing tool, though, if used correctly. 

I was wondering what are some options I may have as a "rookie" investor.

They work for you...typos and other errors on a listing shows incompetence.

Also, doing a brick pattern with floor tile allows a little bit more error as a crooked grout line isn't as noticeable when they are spaced apart.

I still don't know if these errors are good-faith or bad-faith mistakes but never trust anyone that says "I think you could put $10K into it and raise the value $50K".

If your numbers are conservative you have a big margin for error before you would lose money, that's a good thing.

I would agree that in your sixties, you wiggle room for error would be reduced.

The percentage of ownership should be spelled out in the LLC docs as should the exit strategy.If the LLC docs call you all equal members, @Uriah D. may be right - you may technically own 1/3 of the LLC.If that's the case - and an attorney is the way to discern that - you have to decide if you want to blow up a relationship with your partners over an error in how the LLC was set up.  

Regardless, I realize the errors of our ways.I could go into far more detail, but my question is, should I sell my house, and take the equity after closing to pay off my CC debt, and rent for a couple years (or more) and start over?

Learn through training, mentors, trial & error, etc.Since you need clients to make money, how do you plan to acquire them?
