Break-Even Occupancy and Payback: A Worked Example on a Saudi Block

A step-by-step calculation of how empty a Saudi apartment block can get before it stops covering its costs and its debt, and how long the equity takes to come back.

Break-even occupancy is the proportion of units that must be let for the asset to cover its operating costs and its debt service. Payback is how long the cash it produces takes to return the equity you committed. Both are blunt measures, and both tell you something a yield cannot: how much room you have before the deal stops working. The calculation below is illustrative and shows the method on a small residential block.

The situation

An investor is considering a sixteen-unit residential block held for income. The seller has supplied a rent roll and a year of invoices. The investor wants to know how far occupancy could fall before the building stops paying for itself, and how long the equity would take to return at the base case.

Assumptions (illustrative)

• Sixteen units, all of similar size, with an assumed achievable rent of SAR 45,000 per unit per year.
• Gross potential rent: 16 multiplied by SAR 45,000.
• Assumed operating costs, largely fixed regardless of occupancy: SAR 190,000 per year.
• Assumed purchase price SAR 7,000,000, with acquisition costs assumed at SAR 480,000.
• Assumed debt of SAR 3,600,000 with assumed annual debt service of SAR 290,000.
• Assumed bad debt allowance of 2 per cent of billed rent, and no capital spend in the first two years.

Step 1: Gross potential rent at full occupancy

16 units multiplied by SAR 45,000 equals SAR 720,000 per year.

This is the ceiling, not a forecast. Every figure below is a deduction from it, and the gap between this number and what reaches you is where the whole analysis lives.

Step 2: Operating break-even occupancy

SAR 190,000 of operating costs divided by SAR 45,000 of rent per unit equals 4.22 units, so 5 units let, which is 31 per cent of the sixteen.

With no debt, the building covers its running costs once about five units are let. That large cushion is what makes an unlevered income asset relatively forgiving in a weak letting market.

Step 3: Break-even occupancy including debt service

SAR 190,000 plus SAR 290,000 equals SAR 480,000. Divided by SAR 45,000 equals 10.67 units, so 11 units let, which is 69 per cent of the sixteen.

Debt moves the break-even point from five units to eleven. The building must stay more than two thirds let simply to stand still, and that is the number to compare against the worst letting year the asset has ever had.

Step 4: Base case net operating income

Assume 90 per cent occupancy: SAR 720,000 multiplied by 0.90 equals SAR 648,000. Less 2 per cent bad debt, SAR 12,960, gives SAR 635,040. Less operating costs of SAR 190,000 gives net operating income of SAR 445,040.

This is the figure that valuation and cover ratios use. Note that the two deductions above it, occupancy and collection, removed about SAR 85,000 before any cost was counted.

Step 5: Cash to equity after debt service

SAR 445,040 less SAR 290,000 of debt service equals SAR 155,040 before tax and before any capital spend.

Against equity of SAR 7,000,000 plus SAR 480,000 of acquisition costs less SAR 3,600,000 of debt, which is SAR 3,880,000, that is a cash return on equity of about 4.0 per cent in the base case.

Step 6: Simple payback on equity

SAR 3,880,000 of equity divided by SAR 155,040 of annual cash equals about 25 years.

Payback on income alone is long, which is true of most standing income assets. It tells you plainly that the return depends on rental growth and on the exit value rather than on the income recovering your capital.

Step 7: Debt service cover at base and at break-even

At base case, SAR 445,040 divided by SAR 290,000 equals a cover ratio of about 1.53 times. At 75 per cent occupancy, net operating income is SAR 720,000 multiplied by 0.75, less 2 per cent, less SAR 190,000, giving SAR 339,200, and cover of about 1.17 times.

A fall of fifteen percentage points in occupancy takes the cover ratio from comfortable to tight. If a facility required a minimum cover level, that is the point at which a covenant conversation begins.

What changes the answer

• Achievable rent 10 per cent below assumption reduces base net operating income to about SAR 381,536 and lifts the levered break-even to roughly 12 units.
• Operating costs 20 per cent higher than assumed, at SAR 228,000, raise the levered break-even to about 11.5 units and cut cash to equity by SAR 38,000.
• An increase in debt service of SAR 60,000 moves levered break-even above 11 units and reduces cover at base case to about 1.27 times.
• A capital spend of SAR 250,000 in year two consumes more than one and a half years of base case cash to equity.
• Taking the debt to SAR 4,800,000 raises returns in good years but pushes levered break-even towards thirteen of sixteen units.

What the numbers tell you

• Break-even occupancy is the clearest single test of how much bad news a deal can absorb, and it is driven mostly by the debt.
• Compare break-even against the building's worst historic letting year, not against its current occupancy.
• Operating costs are largely fixed, so occupancy losses fall almost entirely on your cash rather than being shared.
• Long payback on income is normal for standing assets, which means the exit assumption carries the return and deserves the most scrutiny.
• A cover ratio quoted only at base case hides the question that matters, which is where it sits in a poor year.

Limits of this example

Every figure above is an illustrative assumption used to show the method, not a quote, valuation or market rate. Costs, rates, fees and regulations change and must be confirmed with the relevant authority, lender or supplier before you commit.
