Chapter: Mastering Economic Criteria: Single vs. Multifamily

This chapter delves into the critical economic criteria used to evaluate single-family and multifamily real estate investments. Understanding these criteria is paramount to making informed investment decisions and maximizing returns. We will explore the theoretical underpinnings, practical applications, and comparative analysis of key metrics in both property types.

1. Introduction: Economic Criteria in Real Estate

The economic criteria for real estate investment provide a framework for quantifying the potential financial performance of a property. These criteria allow investors to objectively assess a property’s profitability, risk, and overall investment suitability. The core economic criteria centers on:

• Price Range: The acceptable range of purchase prices aligned with the investor’s capital and financial goals.
• Discount: The percentage or absolute dollar amount below market value that the investor aims to acquire the property. This reflects the margin of safety.
• Cash Flow: The net income generated by the property after all operating expenses and debt service are paid.
• Appreciation: The expected increase in property value over time.

Ultimately, the price paid for a property (after any acquired discount) largely dictates the future cash flow and appreciation potential. Consideration must also be given to:

• Hassle: The time, effort, and management intensity associated with the property, especially concerning tenant relations.
• Liquidity: The ease and speed with which the property can be converted into cash.

These factors are often counter-cyclical and influenced by macroeconomic trends.

“Multifamily properties, in contrast, are bought and sold largely by investors, and this means that their prices are determined dispassionately by the value of the rents they represent.” - The Millionaire Real Estate Investor

2. Theoretical Foundations: Valuation and Investment Metrics

Several fundamental theories and principles underpin the economic analysis of real estate.

2.1. Discounted Cash Flow (DCF) Analysis

The cornerstone of investment valuation.

DCF analysis estimates the present value of expected future cash flows, discounted at an appropriate rate. This rate reflects the time value of money and the risk associated with the investment.

Formula:

PV = CF1 / (1+r)^1 + CF2 / (1+r)^2 + ... + CFn / (1+r)^n + TV / (1+r)^n

Where:

• PV = Present Value
• CFt = Cash Flow in period t
• r = Discount Rate
• n = Number of periods
• TV = Terminal Value (estimated value of the property at the end of the holding period)

Application: DCF analysis is crucial for both single-family and multifamily investments. However, accurately forecasting future cash flows for multifamily properties requires analyzing rent rolls, vacancy rates, and operating expenses across multiple units, increasing complexity. Single-family cash flow projections are generally simpler, based on one rental unit.

2.2. Capitalization Rate (Cap Rate)

Used primarily for income-producing properties (multifamily).

The cap rate is a measure of a property’s unleveraged rate of return. It’s calculated by dividing the Net Operating Income (NOI) by the property’s value or price.

Formula:

Cap Rate = NOI / Property Value

Where:

• NOI = Net Operating Income (Gross Income - Operating Expenses excluding debt service)

Application: Cap rates are widely used to compare the relative value of different multifamily properties within a specific market. A lower cap rate generally indicates a higher property value, assuming comparable NOI. Single-family rentals can be assessed using a cap rate, but it’s less common as appreciation often plays a more significant role in the overall return.

2.3. Internal Rate of Return (IRR)

Comprehensive profitability metric.

IRR is the discount rate that makes the net present value (NPV) of all cash flows from a particular project equal to zero. It represents the annualized effective compounded rate of return.

Application: IRR is a crucial metric for evaluating both single-family and multifamily investments, especially when comparing projects with different cash flow patterns and holding periods. It accounts for the timing of cash flows, providing a more complete picture of profitability than simpler metrics like cap rate.

2.4. Net Present Value (NPV)

Determines if investment adds value.

NPV calculates the difference between the present value of cash inflows and the present value of cash outflows over a period of time. It’s used in capital budgeting and investment planning to analyze the profitability of a projected investment or project.

Formula:

NPV = ∑ (CFt / (1+r)^t) - Initial Investment

Where:

• CFt = Cash flow during the period t
• r = Discount Rate
• t = the time of the cash flow
• ∑ = summation symbol

Application: NPV is used to compare whether a project will add or decrease value to a company. Positive NPV indicates that the projected earnings generated by a project or investment exceeds the anticipated costs (expressed in today’s dollars).

2.5 Gross Rent Multiplier (GRM)

A quick ratio.

GRM is a calculation of how much an investor is willing to pay for each dollar of gross rent.

Formula:

GRM = Property Price / Gross Rental Income

Application: GRM is most often used to evaluate single-family properties, and can be inaccurate if it is not compared to properties with similar operating expenses.

3. Comparative Analysis: Single-Family vs. Multifamily

The following table summarizes the key differences in economic criteria between single-family and multifamily investments:

3.1. Cash Flow Dynamics

• Single-Family: Cash flow is highly dependent on individual tenant quality, vacancy periods, and maintenance expenses related to a single unit. Seasonality can also impact cash flow (e.g., higher vacancy in winter).
• Multifamily: Cash flow is diversified across multiple units, mitigating the impact of individual vacancies. Economies of scale can lead to lower per-unit operating expenses.

3.2. Appreciation Drivers

• Single-Family: Appreciation is primarily driven by broader market trends, including population growth, employment rates, school district quality, and overall economic conditions. Emotional factors play a significant role, as owner-occupants are often willing to pay a premium.
• Multifamily: Appreciation is more closely tied to the property’s ability to generate income. Rising rents, increased occupancy, and improved property management can all contribute to higher property values. Institutional investors prioritize data-driven financial performance, making price less sensitive to emotional factors.

“Investors are buying cash flow when they purchase rental properties. In the section on the Acquisition Model we’ll walk you through the process of how investors determine a property’s value from Net Operating Income (NOI), which is gross rent minus expenses.” - The Millionaire Real Estate Investor

3.3 Risk and Return

• Single-Family: Considered lower risk due to easier financing, lower initial investment, and a broader resale market. However, concentrated risk with reliance on a single tenant is higher. Returns often lower.
• Multifamily: Higher potential returns due to economies of scale and greater control over income generation. Higher risk associated with increased management intensity and market dependence.

4. Practical Applications and Experiments

4.1. Case Study: Comparing Investment Opportunities

Let’s analyze two hypothetical investment opportunities:

• Property A: Single-family home in a suburban neighborhood. Purchase price: \$250,000. Estimated monthly rent: \$1,800. Annual operating expenses: \$5,000.
• Property B: Four-unit multifamily building in an urban area. Purchase price: \$750,000. Estimated monthly rent per unit: \$1,600 (total \$6,400). Annual operating expenses: \$18,000.

Calculations:

Analysis: Property B (multifamily) has a higher cap rate, suggesting a potentially higher return relative to its price. However, consider management costs and vacancy factors.

4.2. Experiment: Market Research and Sensitivity Analysis

1. Identify a target market: Choose a specific geographic area and property type (e.g., single-family homes in a specific zip code, multifamily buildings in a particular neighborhood).
2. Gather data: Collect data on recent sales prices, rental rates, operating expenses, and vacancy rates from reliable sources (e.g., MLS, Zillow, CoStar, local property managers).
3. Perform sensitivity analysis: Use spreadsheet software (e.g., Excel, Google Sheets) to create a pro forma analysis for hypothetical investment properties. Vary key assumptions (e.g., rental rates, vacancy rates, operating expenses) to assess the impact on cash flow and profitability.
4. Evaluate risk-adjusted returns: Calculate the expected IRR and NPV for each scenario, considering the level of risk associated with different assumptions.

4.3. Example Calculation: Breakeven Occupancy Rate for Multifamily

To determine minimum occupancy levels for profitability.

Given:
* Total Potential Rent (all units occupied) = $100,000 annually
* Operating Expenses (fixed) = $30,000 annually
* Debt Service (fixed) = $40,000 annually

Breakeven Point is where total income equals total costs. Therefore, the level of rent (or occupancy) needed to cover expenses:

• Total Annual Costs = Operating Expenses + Debt Service = $30,000 + $40,000 = $70,000

Breakeven Occupancy Rate = (Total Annual Costs / Total Potential Rent) = ($70,000 / $100,000) = 0.70 or 70%

The building must maintain a 70% occupancy rate to break even. Any lower than this, and the building is operating at a loss.

5. Criteria Worksheet & Strategic Considerations

As highlighted in the text, developing a criteria worksheet is critical for disciplined decision making. Key elements to consider include:

• Location: Country, State/Province, County/Parish, City/Town, Neighborhood, Street. Consider: Taxes, rental laws, weather, crime, transportation, shopping/recreation, traffic, lot size, zoning
• Type: Single Family, Home, Condo, Town Home, Duplex, Fourplex, Large Multifamily. Consider: New/Resale, Urban/Suburban/Rural, Resort/Vacation, Farm/Ranch.
• Economic: Price Range (From \$X to \$Y), Discount (Z%), Cash Flow (\$A/month), Appreciation (B%/year)
• Condition: Needs No Repair, Needs Minor Cosmetic, Needs Major Cosmetic, Needs Structural, Needs Demolition.

Strategic Considerations:

• Middle of the Market: Aim for properties in the middle of the market, where the largest pool of renters and buyers exist. This increases demand and drives appreciation.
• Discount is Key: Prioritize acquiring properties at a discount to market value. This provides a “margin of safety” and built-in equity.
• Cash Flow Needs: Determine your required monthly cash flow per unit or property based on your financial goals.

“When we started out, we decided our basic formula was to put down 20 percent cash, buy at least 10 percent below market value, and cash flow of a minimum of $200 a month after taxes, insurance, principal and interest, and property management fees. And it had to do that on a 15-year payout.” - The Millionaire Real Estate Investor

6. Conclusion
