Those who run such a failed operation surely will have significantly degraded the assets and operations as well.

Are there any insurance companies that people would recommend for this investment strategy that do operate in the Austin, TX area?

Non-profits and/or sober living operators may also be interested, depending on their needs.

Yes this is a Refi on a commercial property with additional large cash out included for sole purpose of reinvesting into another property, as well as a large operating line of credit in addition to the Refi is included.

We are going to be operating separately from the school.

Converting debt to equity if allowed by the operating agreement is not indicative of a Ponzi Scheme.  

Hi everyone, We are looking into a deal to purchase a 5 unit apartment building that currently operates as a short term rental.

I inquired about the possibility of a two-company structure: A traditional LLC that is the public face of the activities (collecting rents, paying contractors, etc.) and managing the Series LLC with each property in once cell in it (in this case, Series LLC is serving as a holding role).Again, one attorney said that would be much better than a standalone LLC and that is recommended approach, and the other said it is waste of time and money since there are some requirements from Texas Real Estate Commission, which is requiring being a licensed broker in the state to operate in the managing LLC.So, just want to hear what other Texas investors are doing when it comes to series LLCs regarding these issues. 

Simple as that. 

In the next 5 years, we can buy one property per year with 25% down (~100K), and perform the same operation of using cash-flow for paying off properties next 15 years and we will have $15K/month net-profit which hits our goal adjusted for inflation (assumed at 3%).
