Gross Income Multiplier: Understanding Easy And How To Calculate It

The gross income multiplier, or GIM, provides a simple way to value commercial or investment assets using sales and rental data. Because it only needs two pieces of information to compare properties or extrapolate comparable property value, this calculation excels in its simplicity.

Due to the GIM’s lack of consideration for a property’s operational costs, the predicted value may not accurately reflect the whole property value. Furthermore, the GIM might not provide a comparable metric if the properties differ.

Gross Income Multiplier

A rough estimation of a property’s value is the gross income multiplier (GIM). It is computed by dividing the asset’s sale price by the annual gross rental revenue.

Investors can utilize the GIM with other techniques like the capitalization rate (cap rate) and discounted cash flow approach to value commercial real estates projects like shopping centers and apartment buildings.

Key Takeaways: 

  • The gross income multiplier provides a rough estimation of an investment property’s value.
  • GIM is computed by dividing the asset’s sale price by the annual gross rental income.
  • Because the GIM does not account for an income property’s running expenses, investors shouldn’t use it as their only valuation metric.

Understanding The Gross Income Multiplier

Before signing a real estate contract, each investor must value the investment property. But there isn’t an easy way to do it like other investments, like stocks. Many seasoned real estate investment property investors concur that a property’s income is far more significant than its growth.

A common statistic in the real estate sector is the gross income multiplier. Similar to how the price-to-earnings (P/E) ratio is used to appraise companies in the stock market, it can be used by investors and real estate experts to determine roughly whether a property’s asking price is a fair deal.

The value of the property taxes or the price at which it should be sold is obtained by multiplying the GIM by the gross annual income of the property. A property may be a more appealing investment if the gross incomes it generates is lower than its market value, which is indicated by a low gross income multiplier.

What Is The Meaning Of Gross Income Multiplier?

The Gross Income Multiplier calculation’s outcome is similar to the price-to-earnings ratio for a share of stock.(gim real estate)  It shows the income generated by the sales price. Or, some investors use it to calculate how long it would take to use the gross income to pay off a property. Therefore, a lower GRM would result in a quicker payoff.

For instance, a property with a GIM of 5 would be paid off more quickly than one with a GIM of 9.

Gross Income Multiplier Formula

The future gross income (PGI) or the adequate gross income (EGI) for a property may be used to construct the gross income multiplier calculation:

Gross Income Multiplier Formula

Potential Gross Income (PGI) and Effective Gross Income (EGI) vary primarily in that PGI examines all sources of income for a property without taking any deductions. On the other hand, adequate gross income begins with the future gross income and then deducts vacancies and collection losses.

Since there are various ways to compute the gross income multiplier (GIM), it is critical to understand how the GIM is determined and to apply a consistent methodology when making comparisons.

Example Of A Gross Income Multiplier

An example will help explain the Gross Income Multiplier’s operation.

Let’s say that an investor is considering buying a house with a $5,000,000 asking price (the sales price) and a $350,000 annual gross income.

The Gross Income Multiplier, in this case, would be 14.2 or $5,000,000 divided by $350,000.

However, this calculation can be unduly straightforward. To handle this issue, investors should know two versions of the Gross Income Multiplier.

Potential Gross Income Multiplier 

Not all properties are fully occupied or earn as much money as possible. Investors who view these properties may perceive a chance to boost revenue/occupancy through more aggressive marketing or improved management. An investor would wish to determine the Potential Gross Income Multiplier in this case.

The Possible Gross Income Multiplier, as its name implies, considers all potential income that a property may generate. As a result, it is determined using the formula: Sales Price / Total Potential Rental Income. The Gross Revenue Multiplier will most likely drop with the addition of the additional prospective income, reducing the time required to pay for the property out of income.

Effective Gross Income Multiplier 

The “Effective” Gross Income Multiplier, which utilizes a monthly income figure rather than an annual income figure, is the second variant. By doing this, the income multiplier computation might be more precisely determined.

Which Is A Good Gross Income Multiplier?

Depending on how you intend to use it, a decent gross income multiplier is generally one that satisfies your needs. Consider the scenario where you demand that any acquisition have a GIM comparable to the market average. If you find five similar properties and determine their average gross income multiplier is 7, a property under consideration might benefit from a gross income multiplier close to that average.

A decent gross revenue multiplier for value purposes is based on comparable properties with really equivalent features, in the opinion of the appraiser.

It’s essential to recognize that the gross income multiplier does not account for any operating expenses, capital investments, appreciation, or potential future changes in income. Therefore, even if a property has a high gross revenue multiplier, it could still be a poor investment. On the other hand, a property may have a low gross income multiplier compared to a group of comparable properties yet still be a better investment depending on your investment strategy or operational advantages.

Gross Income Multiplier vs Cap Rate

Raters calculate a property’s market value using the overall capitalization rate:

capitalization rate

Several methods can be used to estimate the cap rate, including the band of investment method and derivation from similar sales. However, gross income multipliers can also calculate the overall capitalization rate. Let’s examine how this functions.

Sometimes severe data requirements for comparables make it impossible for appraisers to calculate an overall market capitalization rate. The cap rate can be calculated using this gross income information along with the net operating income ratio if there are still recent and trustworthy transaction data that include the gross income for comparable properties.

The ratio of net operating income to adequate gross income is known as the net income ratio (NIR). Because NIR = 1 – OER, the operating expenses ratio (OER) and the net income ratio (NIR) are complementary.

Gross Income Multiplier vs Gross Rent Multiplier

What differentiates the gross rent multiplier from the gross income multiplier? The gross income multiplier considers all sources of income for a property, including rent. In contrast, the gross rent multiplier solely considers a property’s gross income and excludes revenue from other sources.

  • Gross Income Multiplier: Sales Price / Gross Income
  • Gross Rent Multiplier: Sales Price / Gross Annual Rental Income

The main distinction is that the Gross Income Multiplier (GIM) considers all property income sources, including rent and extra fees from things like parking, vending, late fines, or pet rent. This should be obvious from the calculations.

The Gross Rent Multiplier (GRM) only considers rental income.

These measurements are employed in a comparable manner other than one little distinction.

Real Estate investing using private equity and the gross income multiplier

The real estate market, comparable properties, operating expenses, and debt payments are just a few variables determining a property’s value. Then, it requires a whole other skill set to use the resulting value in a purchase or sell negotiation.

The point is that purchasing or selling a commercial property can be challenging and takes years and numerous transactions to master. Therefore, it is typically best for individual investors seeking exposure to commercial real estate assets to work with a specialist – such as a private equity firm – to complete the acquisition.

In such a collaboration, the private equity firm manages all the intricate details of the purchase and sale, allowing the individual investor to take a back seat and use their skills.

Limitations Of The Gross Income Multiplier Method

The GIM is a fantastic place to start for investors looking to assess potential real estate assets.(effective gross income) That’s because it’s simple to compute and gives a general idea of what buying the home would entail for a buyer.

Although the gross income multiplier is scarcely a useful valuation model, it does provide a quick starting point.

However, as was already indicated, there are several problems and restrictions when using this number to estimate the value of investment properties.

The multiplier approach’s use as a crude valuation method naturally raises a counterargument. Sources, revenue, and expenses are not expressly taken into account since changes in interest rates—which impact discount rates in Time value of money calculations—have an impact.

Additional disadvantages include:

  • The GIM approach counts on consistency in properties between related classes. Practitioners are aware from experience that expense ratios for comparable properties frequently vary due to things like deferred maintenance, the property’s age, and the property management’s caliber.
  • Property is bought primarily based on its net earning potential. However, the GIM assesses value based on gross income rather than net operating income (NOI). It is certainly conceivable for two homes with substantially different gross revenues to have the same NOI. (gross annual rental income) Because of this, persons unaware of the GIM method’s limitations may utilize it inappropriately.
  • The remaining economic life of comparable properties is not taken into account by a GIM. A practitioner can give the exact valuations to a new property and a property 50 years old by disregarding the remaining economic life, provided that they produce the same amount of income.

The Bottom Line

In this post, we defined the gross income multiplier (GIM), went through the GIM formula, explained how to calculate it, spoke about what a good GIM is, and then contrasted the GIM with the cap rate gross rent multiplier.

We discussed one-way appraisers could estimate the capitalization rate using the effective gross income multiplier in our discussion of the capitalization rate.

Finally, we covered a few of the gross income multiplier’s restrictions that you should be aware of.

Frequently Asked Question About Gross Income Multiplier

What is a good gross income multiplier?

Gross Income Multiplier Formula

A “good” GRM mostly depends on your home’s kind of rental market. However, it would help if you aimed for a GRM of 4 to 7. A lower GRM indicates a quicker payoff of your rental property. Again, though, it all depends on the market you’re buying.

What distinguishes GRM and GIM from one another?

capitalization rate

An informal, back-of-the-envelope approach for determining the value of the real estate that generates revenue is the Gross Rent Multiplier (or GRM). The gross rent multiplier, referred to as the GIM or Gross Income Method, enables investors to assess potential investment properties based on rental income.

How to use Gross Income Multiplier?

understanding gross income multiplier

The gross income multiplier provides a rough estimation of an investment property’s value. GIM is computed by dividing the asset’s sale price by the annual gross rental income. Because the GIM does not account for an income property’s running expenses, investors shouldn’t use it as their only valuation metric.

What does the 2% real estate rule mean?

Is the “two percent rule” accurate? In real estate, the two percent rule specifies what portion of the overall cost of your residence you should charge in rent. In other words, to make it worthwhile, you need to want at least $6,000 per month for a $300,000 house.

What exactly does effective gross income multiply mean?

The Effective Gross Income Multiplier establishes the link between the Effective Gross Income and the Value or Price. The calculation is as follows: Sale price Effective Gross Income Multiplier. Instead of using the annual income, the effective gross monthly income multiplier would do so.
