Real Estate Investment
1. **Problem 1: Lease Analysis**
We calculate the effective rent to the owner for each lease option using an 8% discount rate. The effective rent is the present value (PV) of the rent cash flows over 3 years.
**Formula:**
$$PV = \sum_{t=1}^3 \frac{R_t}{(1 + r)^t}$$
where $R_t$ is rent in year $t$, $r=0.08$.
---
a. Net lease with steps:
- Year 1 rent: $20$
- Year 2 rent: $21$
- Year 3 rent: $22$
Calculate PV:
$$PV = \frac{20}{1.08} + \frac{21}{1.08^2} + \frac{22}{1.08^3}$$
Calculate each term:
- $\frac{20}{1.08} = 18.5185$
- $\frac{21}{1.08^2} = \frac{21}{1.1664} = 18.0116$
- $\frac{22}{1.08^3} = \frac{22}{1.2597} = 17.4557$
Sum:
$$18.5185 + 18.0116 + 17.4557 = 53.9858$$
b. Net lease with CPI adjustment:
- Year 1 rent: $20$
- Year 2 rent: $20 \times 1.04 = 20.8$
- Year 3 rent: $20.8 \times 1.05 = 21.84$
Calculate PV:
$$PV = \frac{20}{1.08} + \frac{20.8}{1.08^2} + \frac{21.84}{1.08^3}$$
Calculate each term:
- $\frac{20}{1.08} = 18.5185$
- $\frac{20.8}{1.1664} = 17.8373$
- $\frac{21.84}{1.2597} = 17.3293$
Sum:
$$18.5185 + 17.8373 + 17.3293 = 53.6851$$
c. Gross Lease:
- Rent each year: $28$
- Expenses year 1: $8$, year 2: $9.5$, year 3: $11$
- Owner net rent = Rent - Expenses
Calculate net rent:
- Year 1: $28 - 8 = 20$
- Year 2: $28 - 9.5 = 18.5$
- Year 3: $28 - 11 = 17$
Calculate PV:
$$PV = \frac{20}{1.08} + \frac{18.5}{1.08^2} + \frac{17}{1.08^3}$$
Calculate each term:
- $18.5185$
- $\frac{18.5}{1.1664} = 15.8653$
- $\frac{17}{1.2597} = 13.4893$
Sum:
$$18.5185 + 15.8653 + 13.4893 = 47.8731$$
d. Gross Lease with Steps and Expense Stop:
- Rent year 1: $27$, year 2: $28$, year 3: $30$
- Expense stop: $8$
- Expenses: year 1: $8$, year 2: $9.5$, year 3: $11$
- Owner pays expenses above stop:
- Year 1: $8 - 8 = 0$
- Year 2: $9.5 - 8 = 1.5$
- Year 3: $11 - 8 = 3$
Owner net rent = Rent - owner paid expenses:
- Year 1: $27 - 0 = 27$
- Year 2: $28 - 1.5 = 26.5$
- Year 3: $30 - 3 = 27$
Calculate PV:
$$PV = \frac{27}{1.08} + \frac{26.5}{1.08^2} + \frac{27}{1.08^3}$$
Calculate each term:
- $\frac{27}{1.08} = 25$
- $\frac{26.5}{1.1664} = 22.7223$
- $\frac{27}{1.2597} = 21.4233$
Sum:
$$25 + 22.7223 + 21.4233 = 69.1456$$

2. **Problem 2: Income Approach Valuation**
Estimate market cap rate $r$ from comparables:
$$r = \frac{NOI}{Sales Price}$$
Calculate for each:
- A: $\frac{375000}{4167000} = 0.08997$
- B: $\frac{220000}{3140000} = 0.07006$
- C: $\frac{500000}{5500000} = 0.09091$
Average cap rate:
$$r = \frac{0.08997 + 0.07006 + 0.09091}{3} = 0.08365$$
Value of subject property:
$$Value = \frac{NOI}{r} = \frac{450000}{0.08365} = 5381763.5$$
---
3. **Problem 3: Cost Approach Valuation**
Calculate value:
- Cost new improvements: $30 \times 4000 = 120000$
- Depreciation: $3\%$ of $120000 = 3600$
- Depreciated value improvements: $120000 - 3600 = 116400$
- Total value = Land value + depreciated improvements
$$Value = 100000 + 116400 = 216400$$

4. **Problem 4: Investment Pro Forma & Performance**
Given:
- Purchase price: $1,500,000$
- Loan: 80% = $1,200,000$
- Interest: 10%, 30 years
- NOI year 1: $500,000$, grows 2% annually
- Building value grows 2% annually
- Building/improvements = 80% of value
- Depreciation life: 27.5 years
- Tax rate: 28%
- Sale after 3 years
**Step 1: Calculate loan payment (PMT):**
$$PMT = P \times \frac{r(1+r)^n}{(1+r)^n - 1}$$
where $P=1,200,000$, $r=\frac{10\%}{12}=0.008333$, $n=360$ months
Calculate monthly payment:
$$PMT = 1200000 \times \frac{0.008333(1.008333)^{360}}{(1.008333)^{360} - 1} = 10532.99$$
Annual payment:
$$10532.99 \times 12 = 126395.9$$
**Step 2: NOI for years 1-3:**
- Year 1: $500,000$
- Year 2: $500,000 \times 1.02 = 510,000$
- Year 3: $510,000 \times 1.02 = 520,200$
**Step 3: Calculate depreciation:**
- Building value year 1: $1,500,000 \times 0.8 = 1,200,000$
- Annual depreciation: $\frac{1,200,000}{27.5} = 43636.36$
**Step 4: Calculate cash flows and taxes:**
- Interest portion year 1 approx: $1,200,000 \times 0.10 = 120,000$
- Principal paid year 1: $126,395.9 - 120,000 = 6,395.9$
Calculate taxable income:
$$Taxable\ Income = NOI - Interest - Depreciation$$
Year 1:
$$500,000 - 120,000 - 43,636.36 = 336,363.64$$
Tax:
$$336,363.64 \times 0.28 = 94,181.82$$
After-tax cash flow:
$$NOI - Debt Service - Tax = 500,000 - 126,395.9 - 94,181.82 = 279,422.28$$
Repeat for years 2 and 3 similarly.
**Step 5: Calculate sale price at year 3:**
- Value grows 2% annually:
$$V_3 = 1,500,000 \times 1.02^3 = 1,593,060$$
**Step 6: Calculate BTIRR and ATIRR:**
- Use cash flows including sale proceeds minus loan balance.
**Step 7: Unlevered BTIRR and ATIRR:**
- Use NOI and property value without debt.
**Step 8: Break-even Interest Rate (BEIR):**
- Interest rate where BTIRR = 0.
**Step 9: Marginal rate of return from years 2 to 3:**
- Calculate incremental cash flow and IRR between years 2 and 3.
