The law firm of Saul Goodman and Associates must choose between two different leases for their new space. The first lease, Lease A, is a 5-year gross lease with a base rent of $36.25/sf. If rents will increase by $1.00/sf each year and the cash flows from the lease are discounted at 6%, what is the corresponding effective rent when evaluated from the tenant's perspective?
The second lease, Lease B, is a 5-year net lease with a base rent of $25/sf with expenses expected to be $10/sf in the first year. If rents will increase by $1.00/sf each year and expenses by 5% a year, what is the corresponding effective rent from the tenant's perspective if cash flows are discounted at 6% annually?
First Lease:
Initial Rent = $36.25/sf
Gradient = $1/sf
Time=5 years
Rate = 6%
The payments can be split into 2 set of cashflow
i) Annuity of $36.25
ii)Gradient of $1
Hence PV of Annuity = A*(1-(1+r)^-n)/r
=36.25*(1-(1+6%)^-5)/6%
=36.25*(1-1.06^-5)/0.06
=36.25*(1-0.7473)/0.06
=36.25*0.2527/0.06
=$152.70
PV of gradient = G*((1+i)^n-I*n-1)/((1+i)^n*i^2)
=1*((1+6%)^5-6%*5-1)/((1+6%)^5*6%^2)
=1*(1.06^5-0.3-1)/(1.06^5*0.0036)
=1*(1.3382-1.3)/(1.3382*0.0036)
=1*(0.0382)/0.0048
=$7.93
Hence Total PV = 152.70+7.93 = $160.63
Hence Effective Annual Rent can be given by PV= A*(1-(1+r)^-n)/r
or, 160.63 =A*(1-(1+6%)^-5)/6%
or, 160.63 =A*(1-1.06^-5)/0.06
or, 160.63 =A*(1-0.7473)/0.06
or, 160.63 =A*0.2527/0.06
or, A = 160.63*0.06/0.2527
=$38.14
Second Lease
Initial Rent = $25/sf
Gradient = $1/sf
Initial Expense =$10/sf
Growth rate of expense, g = 5%
Time=5 years
Rate = 6%
The rent payments can be split into 2 set of cashflow
i) Annuity of $25
ii)Gradient of $1
Hence PV of Annuity = A*(1-(1+r)^-n)/r
=25*(1-(1+6%)^-5)/6%
=25*(1-1.06^-5)/0.06
=25*(1-0.7473)/0.06
=25*0.2527/0.06
=$105.29
PV of gradient = G*((1+i)^n-I*n-1)/((1+i)^n*i^2)
=1*((1+6%)^5-6%*5-1)/((1+6%)^5*6%^2)
=1*(1.06^5-0.3-1)/(1.06^5*0.0036)
=1*(1.3382-1.3)/(1.3382*0.0036)
=1*(0.0382)/0.0048
=$7.93
Hence Total PV of rent = 105.29+7.93 = $113.22
PV of expense =A*(1-(1+g)^n/(1+r)^n)/(r-g)
=10*(1-(1+5%)^5/(1+6%)^5)/(6%-5%)
=10*(1-(1.05/1.06)^5)/1%
=10*(1-0.9906^5)/0.01
=10*(1-0.9537)/0.01
=10*0.0463/0.01
=$46.29
Total PV of cost = 113.22+46.29 = $159.51
Hence Effective Annual Rent can be given by PV= A*(1-(1+r)^-n)/r
or, 159.51 =A*(1-(1+6%)^-5)/6%
or, 159.51 =A*(1-1.06^-5)/0.06
or, 159.51 =A*(1-0.7473)/0.06
or, 159.51 =A*0.2527/0.06
or, A = 159.51*0.06/0.2527
=$37.87
