The market where the MOB is located is unstable with extensive tenant churning and lease buyouts
occurring regularly. The truth is our 10% vacancy and collection loss estimate is fairly optimistic due to
the perceived stability of current leases. A more realistic estimate (most likely) is 15% and a worst case
(pessimistic) estimate for V&C would be 20%. Let's assign the probability of occurrence as follows: 40%
for most likely, 35% for optimistic and 25% for worst case.
Compute the following
a. BTIRR and ATIRR for each scenario (you already have the optimistic estimate)
b. The expected IRR given the 3 scenarios
C. The variance and standard deviation of IRRs and the coefficient of variation for both before
and after tax
d. Are the expected returns in excess of 12%?
e. Extra Credit: Now, assume that the increase in value for year five is expected to be 6%.
What is the marginal return for keeping the property one additional year? What is your
advice?
