I try to read books on different kinds of realestate investing and house fliping and I do think that they are useful but the information never seems to have a correct fit.

There was a lot of communication on this platform concerning that company but I can not remember their name.   

Correct, think of the IRA as a separate person.

The correct way to measure the overall performance of the investment would be through a Cumulative Return or Compounded Annual Growth Rate (CAGR).

Whether you should use a hard money, broker or private money would depend on your goals & priority (speed, communication, pricing, etc) so highly recommend considering a variety of options!

At the end of the day the PM business is a service business and being unable to communicate with the PM for up to 2 days won’t cut it.

Second, **flexible terms** and clear communication about rates, fees, and loan-to-value (LTV) ratios are essential to avoid surprises.

I think you did the correct thing here. 

But, in the event you really are persuaded that it is important to separate each asset, ensure that whoever is managing the books/monies on the LLCs are doing it 100% correctly as even a small mistake can allow would-be litigants to pierce the corporate veil and render all of it in vein anyway. 

One thing I can tell you for sure: Section 8 renters are more likely to be entitled, difficult, non-communicative, problematic, evicted, trashy, etc.
