A royalty fund is just that a fund where you will receive dividends connected to a multitude of mineral properties, however, there are administrative costs connected with this type of structure and you will not receive an ownership position.
The structure of a TIC is oftentimes compared to a fund since you may appear to have an ownership position of your investment but an exit strategy is almost non-existent. The TIC structure requires you to receive approval from the other participants for liquidation and exiting out of the TIC is very difficult. A Ranger Land and Minerals royalty property provide you independent ownership of your investment with the ability to liquidate at any point in the future without any other participant.
