Analyzing Real Estate Like the Pros

By Jeff Greenspan, Managing Director, Financial Modeling Services

Educated investors know that you can’t put all your eggs in one basket. Real estate is an asset class that provides some very specific time-based and tax-based advantages to an investor (see Table 1), though it is not without its headaches! Unlike investments in the stock market, you can often estimate the future cash flows of a real estate investment with some precision. This, of course, requires financial modeling. So let’s GET STARTED1.

1. Advantages and Disadvantages of Real Estate as an Asset Class.

Advantages Disadvantages
Time Value of Money: money spent on loan payments in the future is worth less than money spent today. Because it is considered less risky than stocks, the overall returns may be less than investing in the stock market.
Leverage: 70-80% leverage is commonly available. Leverage increases your return on investment when used properly. Illiquidity
Tax Advantages: almost every form of real estate has tax advantages, with the tax treatment of depreciation being the most commonly cited. Location specific
Passive Income Generation Requires some level of management, even if you are not the person doing it.
Stability of Cash Flows Tenants: you have to deal with people.
Diversification Toilets: you have to deal with maintenance.
Inflation Hedge Shifting demographics and preferences can affect your returns

All real estate models are designed to estimate future cash flows. Simple models exclude the impact of taxes and are typically used for single-family investments like homes and condos. The most complex models consider the multi-year lifecycle of a property and reflect the cash flows to different levels of investors (general partners vs. limited partners), including those cash flows that are generated when the property is sold. We’ll start by considering a few definitions:

The basic annual analysis looks like this:

PGI - VL + MI = EGI and EGI - OE = NOI

The astute reader will notice that we haven’t said anything about loans or loan payments yet. Most loans come with an amortization schedule that specifies the amount of each monthly payment that goes to pay interest (money to the bank) and the amount that goes to pay principal (additional equity in the property). The entire mortgage payment is an outgoing cash flow, but only the interest payment portion is considered a taxable expense. Now we need two calculations, one for tax purposes and another tracking cash flows:

NOI - Interest Paid = Taxable Income and Taxable Income * Tax Rate = Tax Expense


NOI - CapEx - Debt Service - Tax Expense + Depr = Property Cash Flow

You now have the basic knowledge needed to model the property’s first year cash flow. To model subsequent years, we need to make some basic assumptions about how our revenues (rents) and expenses will change over time. Most models assume a modest increase in rents of 2-3% per year and an equally small increase in expenses, but be careful here, as some expenses change significantly from year to year. Real estate taxes often increase substantially one to two years after a sale because most jurisdictions use the sale price to reset the basis on which you are taxed. It is 100% up to you to research the tax rules in the county in which you are purchasing to understand how much your real estate taxes will increase over time. Management expenses are also likely to change under new ownership.

To model the cash flow in the final year of property ownership, we must add any cash flows from the sale to our last year’s Property Cash Flow. We first calculate the NOI for year n+1. This will seem strange until you recognize the importance of Cap Rates in comparing properties. Go back and look at the definition of NOI and Cap Rate. Most owners assume that the terminal Cap Rate when they sell will be 0.5-1.5% higher than when they purchased: to calculate the expected sales price in year n, we divide the terminal Cap Rate into the NOI from year n+1. Updating the example we used above, if we assume an NOI in year 6 of $95,331 and a cap rate of 10.5%, our expected sales price at the end of year 5 is $1,121,543.

Sales Price - Sales Costs (commissions et al) = Net Sales Proceeds

Net Sales Proceeds - Adjusted Basis (Original Cost – Depr) = Taxable Gain

Taxable Gain - Depreciation Recapture = Capital Gain

We calculate Taxes Due from the property sale by adding Depreciation Recapture taxes (Depreciation Recapture x 25%) to Capital Gains taxes (Capital Gain x Your Capital Gains Tax Rate is between 0% and 20%). Finally, we calculate the Cash Flows from Sale:

Net Sales Proceeds - Loan Balance - Taxes Due from Sale = Cash Flow from Sale

The last piece of information we need is our personal discount rate (see my discussion here), which we use to discount the series of cash flows in order to calculate our Net Present Value (NPV) for this property. We may also want to calculate our Internal Rate of Return (IRR), which we recall is a special case where the NPV equals $0.

It is important to remember that the ability to analyze real estate like a pro does not make you a pro! Only experience can do that. IMHO, real estate can play a critical role in Amassing Long-Term Wealth, but you must be prepared for and able to manage the hassles that come with it.

Finally, Financial Modeling Service can assist you in modeling your real estate project. In addition to analyses like this one, we can perform Loan Analysis and Sell vs. Hold vs. Hold & Refinance analysis. Please contact us and let us know how we can help.
