What drives the unit price up or down?

Simply put, the REIT's earnings.  Currently, an $11.00 unit earns 9% or $0.99 per unit per year.  As the income for the REIT increases and is distributed to our unitholders, we use the baseline 9% to affect the unit price.  For example, with time and through various strategies, the rent goes up, costs remain under control, now we can distribute $1.08 per unit.  That is 9% of $12.00, therefore, our unit value is now $12.00 for new investors to buy in and for existing investors to sell at if they choose to do so.  The distribution rate will not change (9%) only the unit price will go up or down.
