Estimate Startup Costs with Calculator

Startup CAPEX Calculator

Estimates capitalized startup assets only for a commercial property leasing launch.

CAPEX only This calculator covers capitalized startup assets only. It excludes payroll runway, operating expenses, vacancy loss, debt service, tax reserves, inventory, and general working capital. Acquisition down payments and closing items are included inside the property purchase line, not as separate funding needs.

What does the CAPEX tab show?

This CAPEX tab in the Commercial Property Leasing Financial Model Template shows startup costs, Month 3-22 acquisitions, Month 7-27 construction, rent roll, depreciation, and cash reserve checks. Review Month 60 assumptions, with $165k setup CAPEX, $285M purchases, $91M construction, Month 21 breakeven, and Month 52 minimum cash of -$2,882M as validation, not financing or return promise.

What is the biggest cost to start a commercial property leasing business?

For Commercial Property Leasing, the biggest startup cost is usually property acquisition or control. On the owned-property side, the examples here are $12 million for an Office Tower, $9 million for Warehouse One, and $75 million for an Urban Loft, before tenant-ready construction adds another $25 million, $3 million, and $15 million. The real driver is asset type, building condition, location, financing structure, target tenant profile, code readiness, and whether the landlord or tenant pays for improvements.

Owned cost

Acquisition is the biggest cost driver.
$75 million Urban Loft is the top example.
$12 million Office Tower still needs build-out.
$9 million Warehouse One also needs capital.

Cost drivers

Building condition changes upfront spend.
Location affects purchase price and rent.
Code readiness can add major work.
Landlord-funded improvements raise startup cash needs.

How much money do I need to start a commercial property leasing business?

You need from $165,000 for an infrastructure-only Commercial Property Leasing setup to $376 million+ for an owned-asset launch, but cash need is bigger than startup CAPEX because Year 1 EBITDA is -$104 million. Track the cash gap with What Is The Current Growth Rate Of Your Commercial Property Leasing Business? since breakeven arrives in Month 21 and minimum cash hits -$2,882 million in Month 52.

What hidden costs affect commercial landlord working capital?

Commercial Property Leasing can look fine on paper, but working capital gets hit by hidden cash costs that sit outside CAPEX; for a plain-English check on owner economics, see How Much Does The Owner Of Commercial Property Leasing Business Typically Make?. The big drags are vacancy reserves, leasing commissions, legal review, property taxes, utilities during vacancy, repairs before lease-up, lender reserves, insurance deposits, and tenant incentive budgets. Treat $20,000 in monthly fixed overhead and $240,000 of Year 1 payroll as recurring burn before stabilization, because the stress test shows -$104 million Year 1 EBITDA, -$1,286 million Year 2 EBITDA, and minimum cash of -$2,882 million in Month 52.

Commercial Property Leasing Core Five Startup Costs

Property Acquisition And Lease Control Startup Expense

Owned-property cash

Buying space starts with cash, not rent. In this model, owned-property exposure includes $12 million Office Tower, $9 million Warehouse One, and $75 million Urban Loft, inside $285 million total exposure. Budget for the down payment, earnest money, appraisal, title, lender fees, and closing costs before operations begin.

Lease-control cash

Master lease cash is separate from ownership cash. The model uses $30,000 Retail Hub, $20,000 Flex Space, and $25,000 Industrial Park per month, or $75,000 monthly. Size security deposits from months of coverage, then keep them away from operating cash and debt service.

Track deposits by lease
Match cash to coverage months
Hold funds outside payroll

Keep cash separate

Push on terms, not just price. Earnest money, lender fees, and closing costs can move with structure, but only if you negotiate early and keep financing cash, lease-control cash, and reserves in separate accounts. That keeps runway math real and avoids starving the first months of ownership or lease-up.

Reserve discipline

Treat acquisition cash as startup capital, not operating money. Debt service starts after closing, while reserves cover taxes, insurance, and vacancy gaps. If you lump those together, you overstate free cash and underfund the first 6 to 12 months of ownership or lease-up.

Due Diligence, Legal, Zoning, And Professional Setup Startup Expense

Due Diligence

Before you close a site, pay for commercial real estate due diligence, legal review, and entity setup. In this model, that starts with $10,000 for legal entity setup CAPEX and $3,000/month for legal and accounting. These costs protect you before signing tenants or starting construction, but lender, zoning, and environmental reviews can still push timing and cash needs.

What It Covers

Budget for inspections, appraisals, a Phase I environmental report, lease drafting, zoning checks, permits, and advisor time. Estimate each from vendor quotes, site count, and the number of leases in flight. Keep these as pre-close costs, not operating overhead, because they sit ahead of revenue and decide whether a deal can move forward.

Keep It Tight

Keep one counsel panel, ask for fixed fees, and batch work across deals so review hours do not reset for every site. Push early zoning and lender questions up front; that avoids paying for a lease draft on a property that cannot close. The savings are mostly in avoiding wasted work, not in cutting core compliance.

Timing Risk

Environmental, zoning, and lender review can change the acquisition date, so build cash for delay, not just closing day. If a report flags a problem, you may need extra legal work, a revised lease, or more reserve cash before you can sign. That is why this expense belongs in the startup budget, not in rent-ready operations.

Building Readiness, Renovation, And Tenant Improvement Startup Expense

Scope

Readiness spend is the money that makes a space lease-ready before move-in. In this model, the named budgets total $45.1 million across Office Tower, Retail Hub, Warehouse One, Flex Space, Urban Loft, and Industrial Park, while total construction planning is $91 million. That gap shows how fast scope grows when repairs, common areas, and tenant fit-out stack up.

Fit-Out

Tenant improvement cost covers HVAC, electrical, plumbing, ADA access, fire safety, signage, common areas, white-box work, and tenant-ready repairs. Price it from scope counts, contractor quotes, permit needs, and the lease term. A landlord-funded TI allowance lowers tenant cash at signing, but it still belongs in the full project budget.

Count rooms, bays, and systems.
Get two contractor quotes.
Check who funds the work.

Control

Keep the spend tied to asset condition and property class. A rough shell needs more than a clean second-gen suite, and a short lease should not fund a premium buildout. Use phased work, reuse code-compliant finishes, and avoid oversizing systems. Here’s the quick rule: spend only where rent, term, and tenant credit can support it.

Reuse usable finishes first.
Phase noncritical upgrades.
Match scope to lease term.

Lease

For underwriting, separate owned-property cash from lease-control cash. The model uses $12 million Office Tower, $9 million Warehouse One, and $75 million Urban Loft for owned exposure, plus monthly control costs of $30,000 Retail Hub, $20,000 Flex Space, and $25,000 Industrial Park. Keep renovation cash apart from debt service and reserves.

Insurance, Taxes, Escrows, And Risk Reserve Startup Expense

Insurance Stack

Budget $2,500 per month for corporate insurance, or $30,000 a year. That line should cover commercial landlord insurance, commercial property insurance, general liability, umbrella coverage, and any lender-required coverage, so you are not guessing after close.

Reserve Cash

Set aside cash for security deposits, property tax escrows, and a landlord risk reserve before rent starts. Lenders, landlords, and master-lease counterparties may ask for this upfront, and it should sit in working capital, not construction CAPEX.

Working Capital

Keep reserve funding separate from build-out spend. CAPEX means capital expenditure, or money spent to improve the property; insurance, property tax reserve, and vacancy reserve are operating cash needs, not construction costs, so mixing them hides the true launch cash need.

Before Rent Starts

If the lease or loan requires cash held before occupancy, model it as a startup reserve, not a project asset. That keeps the launch budget clean and shows how much cash must be available on day one to protect the landlord, the lender, and the tenant base.

Leasing Operations, Marketing, And Property Management Startup Expense

Lease-Up Base

This startup line funds the leasing engine: $1,500 monthly software, $4,000 corporate marketing, $8,000 office rent, and $1,000 for utilities and supplies. It also pays for broker commissions, listings, lease-up marketing, signage, tenant screening, accounting setup, and early staff support while occupancy is still building.

Year-One Cash Need

Here’s the quick math: fixed overhead is $14,500 per month, or $174,000 a year, before payroll. Add $180,000 for the CEO and $60,000 for the half-time Head of Property Management, and year-one cash need reaches $414,000.

Count runway months.
Price each hire.
Track lease-up volume.

Keep It Lean

Keep spend lean by matching marketing to live listings, using contractors for short bursts, and reviewing software, office, and staffing each month. Don’t cut tenant screening or reporting; weak data can slow collections and make lease-up harder.

Use contractors before hiring.
Link spend to openings.
Protect screening and reports.

Why It Matters

This is the control center before stable cash flow. The team keeps the rent roll, the tenant-by-tenant rent list, clean, pushes reporting on time, and handles service issues fast, so leasing does not stall while the portfolio is still filling.

Compare 3 Startup Cost Scenarios

Scenario table

Startup cost rises fast as you move from one leased or owned property to a multi-asset portfolio, because purchase price, construction, and rent reserves scale faster than office overhead.

Lean, Base, and Full launch cost comparison
Scenario	Lean LaunchLower capital	Base LaunchBalanced launch	Full LaunchAcquisition-heavy
Launch model	Start with limited property control and keep the first launch infrastructure-led.	Start with one stabilized owned property or one master lease, using Month 3 or Month 6 timing as the template.	Build a multi-asset platform with purchases, construction, and active rent-control coverage.
Typical setup	Use one small office setup, light systems, and only the core team.	Keep the asset count to one, use a small team, and fund basic fit-out and lease-up.	Carry several assets, complete heavy construction, and hold enough cash for slow lease-up.
