There are subsidiaries sometimes that might trade stocks or commodities or other investments, but I don't think many are set up to trade residential real estate for a profit based on foreclosures. 

I have established a holding LLC that I am the owner of, and a subsidiary LLC that is wholly owned by the holding LLC.

Then we created a number of subsidiary LLCs at $150 each.

Is it possible for an LLP to have LLC subsidiaries to fulfill an additional layer of protection, how to do it?

Hi Guys,Currently own multiple properties (Sfr),they are spread out into various LLCs, having couple of properties in each LLC.these LLCs are all owned by and a subsidiary of a 1 holding LLC.Rent is currently flowing into 1 bank account, all expenses and income are being segregated and and accounted for with QB and works well.Ive been reading that each LLC should have its own Bank account.. i feel this would be a pain to do..What do you suggest doing? 

My parents could be partners in the company, but preferably, my company would create a subsidiary company to specifically hold these 3 properties with my parents as partners; in the desired scenario, a business partner (non-family member) and I would own the main company.

The LLC is a subsidiary of another LLC of mine.

If they provide the service, it is an ancillary service through a sister or subsidiary company. 

If your subsidiary LLC (the TX one) is a single-member LLC with the one member being the WY LLC, then it's a pass-through for tax purposes (IANAL or a CPA), so you don't have to keep multiple books (but do need separate checking accounts, CC, etc) or do separate tax filings.

From a subsidiary perspective, we decided that each state we invest in gets its own "local" LLC.
