While I agree with this direction, it does make me begin to question why I don't just abstract the entire thing away with a REIT or other similar investment vehicle.

8% off the top depending on your particular scenario could get you pretty close to the same net returns at the end of the day. If you went with a few REITs, management would take maybe a few hours a month even for a massive portfolio. This also has the benefit of being much more diversified than a single investor directly owning various properties could possibly manage.

Granted, using REITs is a tradeoff in granularity of asset allocation and potential upside, so there is always that zone of opportunity to exploit. It just takes a delicate evaluation of the value of your time vs the opportunity itself relative to other competing strategies.
