If corporate is it parent corp across all locations, subsidiary, or just one location backing it, does guarantee burn off after so many years?

I'm pretty confidant that the greenhouse venture in Colorado is solid as it's a subsidiary of a publicly held company.In any event we'll be visiting your beautiful city from the 27-29 and treking down to Pueble to actually see a working greenhouse in progress.

Started as a commodities trader for a subsidiary of Union Bank of Switzerland.

The one I last used is a subsidiary of a major title company.

It's a professionally-run subsidiary, not an ad-hoc afterthought.But up to a point vertical integration doesn't make sense because the management fee from just a few properties doesn't pay for the talent needed to oversee it. 

Particularly since 2008, in the US we're moreover now in "uncharted waters" under UN subsidiary, Maritime Admiralty 'legalese...' but one thing is obvious, those in power (you've likely never heard of) can order the "printing" of (seemingly) unlimited Xs and Os, plus the approx. 2% of fiat monopoly IOUs in physical circulation (IH$ dollar bills, for e.g.)

If a person is say a slumlord who delights in breaking every law available until forced to comply, well than that person should make it a top priority right after therapy, although if your like most landlords looking to make a reasonable profit operating a legal legitimate operation than it is the rare oddball incident we are talking about, and for that insurance is a key piece not building a maze of entities.Myself I operate a s-corp as a parent company under which my other companies are held as subsidiary companies, all formed as LLC's.

For asset protection we have a WY LLC as our holding company (what you are referring to as the "master LLC") with subsidiary LLCs in each of our investment markets to hold the investment properties in those states.

If your goal is to build on a portfolio of rentals it might make more sense (not legal/tax advice) to have an entity structure setup such as S-Corp as holding company with LLC for individual properties as subsidiaries or n# of additional ways you can structure your entity .

Depending on who the Seller is, they may have a bit more detailed ownership structure inside their operation where they hold the asset in a Special Purpose Vehicle or Special Purpose Entity which is essentially just a LLC subsidiary of the parent perhaps with different investors.
