There's no right or wrong way to do this, just varying levels of risk and reward and YOU need to understand what they are for whatever strategy you choose. 

This may be done in person, over the phone, or maybe a zoom.

@Don Konipol  Don talk about a book on this subject by I think its Jimmy Napier which was written years ago But Don says its the bible I personally have not read it As I got my education working for a HML in Oakland CA and got on the job training as it where .He was a legend and I was very fortunate to find my way to his company and then eventually end up running it.

What is the rate and term of the personal loan?

I invest personally as well as help other investors find off-market deals.

MANY times investors do NOT have their mortgages reporting to their personal credit!

This is too important and also sort of a personal question depending on your state and specific circumstance and I suspect not a one size fits all answer would suffice. 

Basically every personal house we ever owned except this last one which we built from scratch.

My question is, how can I structure this to protect myself from a situation where someone sues the LLC and takes the property, leaving me personally liable for the loan?

Systematize as much as possible to create scalability.PM is a challenging but rewarding business.
