Financial Modeling: Investment Property Model


Building financial models is an art. The only way to improve your craft is to make various economic models across several industries. Let’s try a model for an investment that is not beyond the reach of most individuals – an investment property.

Before we jump into building a financial model, we should ask ourselves what drives the business we are exploring. The answer will have significant implications for how we construct the model.

Financial Modeling: Investment Property Model 1

Who Will Use It?

Who will use this model, and what will they use it for? A company may have a new product for which they need to calculate an optimal price. Or an investor may want to map out a project to see what kind of investment return they can expect.

Depending on these scenarios, the result of what the model will calculate may be very different. Unless you know exactly what decision the user of your model needs to make, you may start over several times until you find an approach that uses the right inputs to find the appropriate outputs.

On to Real Estate

Given specific information about the investment, we want to determine what kind of financial return we can expect from an investment property. This information would include variables such as the purchase price, rate of appreciation, the cost of renting it out, the financing terms available for the property, etc.

Our return on this investment will be driven by two primary factors: our rental income and the appreciation of the property value. Therefore, we should begin by forecasting rental income and the appreciation of the property in consideration.

Once we have built out that portion of the model, we can use the information we have calculated to figure out how we will finance the purchase of the property and what financial expenses we can expect to incur.

Next, we tackle the property management expenses. We must use the property value we forecasted to calculate property taxes, so we must build the model in a particular order.

We can piece together the income statement and the balance sheet with these projections. As we put these in place, we may spot items we haven’t yet calculated and have to go back and add them in the appropriate areas.

Finally, we can use these financials to project the cash flow to the investor and calculate our return on investment.

Laying Out the Model

We should also consider how to lay it out to keep our workspace clean. One of the best ways to organize financial models in Excel is to separate particular model sections on different worksheets.

We can give each tab a name that describes its information. This way, other model users can better understand where data is calculated in the model and how it flows.

Let’s use four tabs in our investment property model: property, financing, expenses, and financials. Property, financing, and expenses will be the tabs on which we input assumptions and make projections for our model. The financials tab will be our results page, where we will display our model’s output in an easily understood way.
