Where Are Values Headed?

By Dale C. Eisenman, CCIM, and Michael Morrison

After a period of high transaction activity for the past few years, the market has continued to be strong into 2018. Many of our clients and potential clients are faced with attempting to decide if they should hold their property, based on the fact that facilities are performing at a high level, or to sell their property before interest rates rise and new supply saturates the market.

My crystal ball is no more accurate in predicting the future than yours, but I do think we can look at some probable scenarios to create a framework within which to consider where values are headed.

To start, consider the following self-storage property located in a mid-size market with good visibility. Let’s assume it is a 50,000-square-foot facility, 90 percent occupied, and market rents are $10 per square foot per year on average. The revenue and income would look like this:

Gross Potential Income $500,000
Vacancy $50,000
Effective Gross Income $450,000
Operating Expenses $157,500
Net Operating Income $292,500
Seven Percent Cap Rate $4,178,571

As we can see, this property has a value of $4,178,571 at a capitalization rate of seven percent. Now, let’s assume a buyer would finance 75 percent of that value ($3,133,928) at 4.75 percent with an amortization over 25 years. The annual debt service would be $214,404. Subtracted from the net operating income of $292,500, the cash flow (before tax) is $78,096. That represents a cash-on-cash return to the buyer of 7.47 percent (78,096/1,044,642). While 7.47 percent cash-on-cash return may not be adequate for many buyers, we will assume it is the target rate for the purposes of this article.

For the sake of our crystal ball, let’s now assume the very same situation but with an interest rate change from 4.75 percent to six percent. The annual debt service increases to $242,304, and the before tax cash flow falls to $50,195, which represents a 4.8 percent cash-on-cash return.

If the buyer has a 7.47 percent cash-on-cash return target, what must the value of the property be to generate such a return at a six percent interest rate? With the higher interest rate, the buyer will see more cash from the net operating income go to service the debt. Accordingly, the buyer cannot afford to pay a price equal to a seven percent capitalization rate. But how much higher must the cap rate go to achieve the same cash-on-cash return for the buyer?

If we consider the same property valued using a 7.67 cap rate, we find that a buyer will achieve the desired cash-on-cash return with a six percent interest rate. But note, the seller now has seen a decrease in value (sales price) of $364,985. Another way of looking at the situation is that the seller has just lost over $350,000 in value simply with a 1.25 point increase in interest rates. The importance of this is that values may decrease if interest rates increase.

When faced with the prospect of selling now versus selling in the future, an owner may wish to consider if interest rates will increase and, if so, at what rate. He may then wish to consider if he believes rental rate increases will be able to be increased at an adequate pace to offset the impact of increasing interest rates.

Often, owners will indicate they choose to wait to sell their property anticipating an improving market and a higher value. But, as this analysis shows, rental rates and/or occupancy increases must outpace interest rate increases if there is to be a net gain in value.

Ask yourself: If interest rates increase 1.25 percent per year, can rental rates be increased seven percent or more per year to maintain or increase value? The public REITs have indicated they are anticipating occupancy to stay flat or decrease in some markets due to new supply and will not be able to push rental rates as they have been able to in the past.

Another issue that needs to be considered is that the self-storage industry has experienced high levels of new development recently. This additional supply may affect the value of nearby properties. New facilities often offer promotions and discounts to build occupancies, particularly during the rent-up phase. That can bring downward pressure on rental rates and result in lower occupancy for existing facilities. That, in turn, results in lower net operating income, ultimately lowering the value of the property. Also, if newly developed properties underperform, some may come under pressure from lenders to sell. If those “troubled” properties are available to purchase, they will compete with other available properties.

What is the take away from all this? If you believe interest rates will increase over time, values will decline unless income increases keep pace or outpace those interest rate increases. Should we experience a rapid increase in interest rates, it may be improbable that increases in income through gains in occupancy and rental rates will be able to offset the negative impact on value. In short, if interest rates increase significantly, values are likely to decrease. Even if values stay constant in the face of rising interest rates, given the time value of money, an owner may be wiser selling sooner rather than later.
