But her formal education and career path took her elsewhere.

There's no formal classification, it's a subjective measure.A - new construction, lots of amenities (nice pool, gym, garages, business center, etc.).  

The only problem is I don't know what niche would be the most advantageous path given my current path of formal education. 

Have you ever gotten a construction lien dismissed (outside of formal foreclosure)?

(but looks like you would for first month)...so back to your situation, which is not clean, but check your state rules and verify without the signed lease, you reverted to the month to month, so I would really document and communicate the end of June move out date (like verbal plus a follow up more formal looking letter) and prepare for the move out then and the painters, etc to come in..

I have read many posts on HOA NOD, NOD Liens and Notice of Trustee Sales, but haven't still seen a definite clear answer to my potential investment on a HOA Non-Judicial Judgement in California NOTS.

There's not much the lenders can do based on my preliminary estimated numbers so until I have the formal pro-forma data from the feasibility analysis, that will have to go on the back burner.

Because as we know lease options in many jurisdictions are treated as JUDICIAL foreclosures take a year and cost a bunch of money...

Most states that use a deed of trust allow non-judicial foreclosure, which is cheap and easy.

Only then, if you have no success, it might be worth paying someone to help you and paying for the formal appeal application.
