Why the vacancy rate of a rental property is important
When evaluating a rental investment, it’s helpful to know the market’s average vacancy rate so you can compare your property’s current performance. Sometimes poorly managed or poorly maintained properties have a higher vacancy rate than the market average. For a prospective buyer, this presents an opportunity to add value by decreasing the vacancy rate, increasing profitability.
I recently evaluated a storage facility that had a nearly 50% physical vacancy rate while its nearby competitors were seeing an average of 10%. Knowing the current vacancy rate and how it related to the average market vacancy rate allowed me to evaluate the property based on its current performance and determine the future potential value of the property.
Rental properties inevitably become vacant at some point, which affects the overall performance and return on investment. Knowing the average vacancy rate, economic vacancy rate, and physical vacancy rate of the property beforehand lets you account for any potential loss in rental income and determine your overall return more accurately.
Calculating the vacancy rate of a rental property
Multifamily properties typically use a vacancy rate that depicts the number of vacant units in real-time. Here's how to calculate the current physical vacancy rate of multifamily properties:
- Multiply the number of vacant units by 100.
- Divide the result by the total number of units in the property.
For example, if an apartment with 10 units has two vacant units, you would multiply 2 x 100, giving you 200. Then divide by 10 units for a 20% vacancy rate.
Single-family properties or other rentals that have one unit for rent typically use an averaged vacancy rate. Here's how to calculate the physical vacancy rate for a single-family rental:
- Take the total time vacant in weeks or days over a given period -- usually one year.
- Divide that number by the total time the unit could've been rented.
For example, if the property was vacant for three weeks, you would divide that by the number of weeks in a year (52) for a physical vacancy rate of 5.8%.
Let's look at the economic vacancy rate next:
- Take the total rent lost during the vacancy period.
- Divide that by the total potential rent that could be collected in a year.
Let's say a single-family home has the potential to collect $1,000 a month. The gross potential rent would be $12,000. The property was vacant for three weeks or 21 days. That's 70% of a month. 70% of the monthly rental rate of $1,000 equals $700 lost. Divide the amount lost by the gross potential rent. $700/$12,000 gives you a 5.8% economic vacancy rate.
What factors affect the vacancy rate in a rental property?
Several factors can affect vacancy rates, such as:
- economic conditions,
- lack of demand for your rental type,
- poor property management and upkeep, and
- overpriced rent.
Vacancy rates often increase during economic recessions due to lack of demand, poor job and population growth, and oversupply. If market conditions are favorable and demand for your property type is high, but you're still seeing higher-than-average vacancy rates, you may need to lower your rent or improve your property to meet the standards of your competition.
It’s important to price your property according to market conditions and set a realistic rent based on its features and condition. In addition, maintaining the property and managing it well will keep tenants happier and reduce turnover.
