The seller and their agent hopefully did a good job communicating with that tenant to set expectations.

Over this time I have acquired my contractor team and have vetted them through my job as a property manager, figured out my strategy(Off Market/Deep buying) and location.

If the LLC and its income are entirely outside California, it typically does not require registration with the California Secretary of State (SOS) or payment of California Franchise Tax Board (FTB) fees, even if you reside in California.

My contractor mentioned he might've left them since he felt bad about up and leaving the job. 

In my experience in MO, land bank properties are very low priced (these are generally properties/parcels that weren't sold at the tax auction), but they often have significant tax liens on them that must be cleared in addition to the "sale price" AND they require a significant amount of rehab in order for the properties to be inhabitable. 

Stable job for 20+ years.

Most states require 27+ days of continuous stay before they are considered a tenant and not a guest.

This attorney should handle creation of your PPM and state filing requirements, but they do not handle the PSA or closing. 

It would be a different story if I were endorsing a business that was not doing a good job.  

It is not something that you can access immediately, like same day.It usually requires 2 Business days to process loan request.
