This will avoid needing to foreign qualify your out-of-state entity in the State you are buying the property in.However I am wondering, if I am forming an LLC, with the sole purpose of buying tax liens (I am a foreign national btw), and I don't wish to limit my tax liens acquisition in just 1 State, but instead buy tax liens all over the US..Do i need to foreign qualify my LLC in EVERY State I buy these liens in?

Yes the DST's can have some limits that might be prohibitive. 

Depreciation reduces the tax liability.

Within the city of Austin and other local markets with limited inventory, homes are spending a fraction of time on the market—as little as two weeks in some areas.

Affirmative evidence of efficacy only, please.My guess is there will not be many replies to this thread with actual success stories, and if there are any, most of them will be in the "my liability insurance paid the claim" category. 

The bad is that often times you will find less care is being taken with your property, the Section 8 has inspections, which at times can be obnoxious and often times you are renting to tenants with no job or limited employment, so they are home all the time, causing more wear on your house. 

The main reasons to have an LLC are privacy and liability protection.

Just my initial thoughts based on the limited information, I wish you the best with whatever you decide.

I request a credit limit increase twice a year on my main card.  

What are the legal ramifications/liability concerns with doing this without an LLC?
