Playbook: Lease Budgeting & Affordability

Why Budgeting Matters in Commercial Leasing

For small businesses and nonprofits, rent is usually the second-largest expense after payroll. Overcommitting to a space that looks great on day one but strains cash flow by year two is one of the most common reasons tenants find themselves stuck in difficult negotiations—or forced to close.

This playbook walks you through how to build a clear, realistic budget before you sign a lease. You’ll learn how to factor in hidden costs, test affordability under different scenarios, and make sure your lease supports growth instead of holding you back.

Step 1: Know Your True Occupancy Costs

Base rent is only the tip of the iceberg. Before setting your budget, you need to understand the full “all-in” picture.

Core categories to include:

• Base Rent: The quoted rate, often listed as dollars per square foot.
• Operating Expenses / CAM Charges: Your share of property taxes, insurance, and common area maintenance.
• Utilities: Electricity, water, gas, internet—sometimes included, often not.
• Tenant Improvements: Any build-out or customization costs not covered by the landlord.
• Insurance & Compliance: Liability coverage, permits, accessibility requirements.
• Parking & Extras: Reserved spaces, signage, storage, or security fees.

Rule of thumb: Add 20–30% to the base rent as a working estimate for extras until you have detailed numbers.

Step 2: Set a Safe Rent-to-Revenue Ratio

A key affordability test is comparing occupancy costs to projected revenue.

• Retail & Restaurants: Rent should typically not exceed 6–10% of gross sales.
• Office & Service Businesses: Closer to 3–8% of revenue is sustainable.
• Nonprofits: Aim for under 10% of total operating budget to preserve flexibility for programs and staffing.

Pro Tip: Build in conservative revenue assumptions. If you expect $1M in sales, test affordability at $800K.

Step 3: Factor in Growth and Flexibility

Locking into the wrong size space can derail your budget. Ask yourself:

• Too big? You’ll overpay for unused space.
• Too small? You’ll outgrow quickly, forcing an early (and expensive) move.
• Expansion options? See if the landlord offers a right of first refusal on adjacent space.
• Exit options? Negotiate assignment or sublease rights in case you need to pivot.

Checklist:

• Project headcount and space needs for 3–5 years.
• Run scenarios for modest, expected, and high growth.
• Consider shared amenities (conference rooms, kitchens) to reduce square footage needs.

Step 4: Stress-Test Escalations & Hidden Costs

Even if the first year fits your budget, will it still work in year five?

Items to stress-test:

• Annual Escalations: Commonly 2–3% fixed increases, or tied to inflation (CPI).
• Operating Expense Pass-Throughs: These can jump unexpectedly if taxes or insurance rise.
• Capital Expenditures: Some landlords try to pass on roof or HVAC replacements—watch for this in the fine print.
• Renewal Options: Ensure renewal rent is tied to fair market value, not an arbitrary increase.

Scenario exercise: Multiply today’s occupancy cost by 1.25 to 1.5. If you can’t sustain that in year three, the lease may be too aggressive.

Step 5: Align Budget With Financing & Cash Flow

• Working Capital: Keep at least 3–6 months of occupancy costs in reserve.
• Seasonality: If revenue dips seasonally, negotiate rent abatement or staggered increases.
• Lender/Board Approval: Many nonprofits and growing businesses need third-party sign-off. Prepare clear affordability models.
• Tenant Improvement Allowance: Negotiate upfront landlord dollars so you don’t drain cash reserves on build-out.

Case Example: A Bakery That Baked in Trouble

A small bakery signed a lease with rent equal to 12% of projected sales. On paper, it worked. But after factoring in CAM charges, utilities, and a surprise 4% escalation clause, total occupancy cost ballooned to nearly 18% of revenue. Within two years, margins were squeezed so tight the business had to relocate at significant expense.

Lesson: Never evaluate base rent alone—your real budget is “all-in plus future increases.”

Key Takeaways

• Calculate true all-in occupancy cost, not just base rent.
• Use safe rent-to-revenue ratios to test affordability.
• Stress-test escalations and hidden costs for years 2–5.
• Align your lease with cash flow, reserves, and growth plans.

A smart budget is your best protection against signing a lease that looks affordable today but becomes a burden tomorrow.
