It’s gaining traction in some areas as a proactive approach to stabilize tenant behavior and reduce defaults.

The majority of that time I was using it for personal gain, buying properties essentially for myself. 

To answer your question, the advantage the GP has is control, and the ability to gain wealth from their equity position (hopefully not so much for asset management fees) by selling at a big gain.  

Southern impression is primarily a single family home builder and their floorplans are all too large for profitability. they are overbuilding each unit and adding unnecessary things like garages that don't get you any income and only drive the construction values up. a garage on it's own isn't with much more than what it's built for and doesn't really add to the equity gain in new construction 

I thought it would be best to gain experience, instead of picking up a job in facilities.

As we flipped this ourselves from the roof to the flooring, we gained much respect to labor workers and realized even the tidiest things such as changing the outlet covers and installing new plumbing will take up a lot of time!

This allows you to take the first $250k ($500k if married) of the gain tax free.

Roth IRAs offer tax-free growth, meaning that rental income, appreciation, and gains generated within the account are not taxed, but you cannot take advantage of deductions like depreciation or mortgage interest on your personal tax return.

What better way to gain insights than go straight to the source on sentiment instead of trying to work backwards with data and reports.

Then start finding properties and I would encourage you to lean towards finding less riskier versions of that strategy at first and get your feet wet, and after you gain some experience you can start evaluating different options and offshoots.
