Once you can properly analyze a t12 and rent roll, then plugging it into a tool will help you spot opportunity.Gino

Let me summarize this for you again, I am not seeking a legal advice, I need hand holding to confirm I am reading the semantics of the deal properly !

Sounds like the expectations just weren’t set properly from the get go?  

Once you learn more about all these different ways then choose the best one that you believe will be the best fit for you that fits your lifestyle and will help you accomplish your goals.

Taxation can be all about the operating agreement.Short of a proper operating agreement a two member LLC must choose to file as a Partnership on Form 1065, C Corp 1120or S-Corp 1120s.Changing title when the property is mortgaged is another issue.

How to you properly charge the tenants seasonal usage (high in winter/low in summer) and when there's not equal gas appliances between the units? 

Trying to figure out the optimal strategy that will provide liability protection, proper estate transfer at death, and other strategies that can benefit their tax situation.I have my ideas, but want to consult with someone who has estate and tax planning experience in CA.

You need to do more than a day of fixups - painting, carpet steam cleaned, cleaning all drawers and appliances, exterior touchups.You have a "perfect" process set out, but it's one that will push you to make a bad tenant decision and not vet them properly.

You could consider it disposable but I am guess the costs to get it safe for habitation will really impact your decision.Regarding the house on stilts, if it is properly engineered it would be considered real property with a unique foundation.

The second lien also means you’re in a junior position if the buyer defaults, so you’ll want to be aware of that risk too.Overall, owner financing can be a win-win, but it’s important to have everything structured properly to protect your interests.Cheers,William
