Rental Arbitrage Calculator

Estimate profit, break-even occupancy, and startup payback before you sign a lease

Rental arbitrage means leasing a property, then operating it as a short-term rental with the owner's written approval. Enter the actual lease, booking, and cost assumptions to see whether the deal has enough margin.

Before you sign a lease

A promising nightly rate is not enough. Check the deal's cushion, upfront cash, and operating permission first.

1

Stress the slow month

Focus on break-even occupancy, not just projected monthly profit. A lower break-even point gives the deal more room when bookings soften.

2

Count all startup cash

Include deposits, furnishings, permits, supplies, and reserves. The payback period matters as much as the headline return.

3

Get written approval

Confirm the lease permits short-term rentals and check local licensing, HOA, insurance, and tax requirements before committing.

Rental Arbitrage FAQ

What is Airbnb arbitrage?

Rental arbitrage (also called Airbnb arbitrage) is when you rent a property on a long-term lease and then sublet it as a short-term rental on platforms like Airbnb or VRBO. You profit from the difference between your fixed monthly rent and the variable income from nightly bookings. It requires less capital than buying property but comes with unique risks and legal considerations.

How much can you make with rental arbitrage?

Rental arbitrage profit depends heavily on rent, local nightly rates, occupancy, regulation, and operating efficiency. Many operators look for deals with meaningful monthly cash flow, a margin cushion, and break-even occupancy low enough to survive slow months.

Is rental arbitrage legal?

Rental arbitrage is legal in many areas, but you must have explicit written permission from your landlord to sublet on Airbnb or VRBO, comply with local short-term rental regulations and licensing requirements, check HOA rules if applicable, and maintain proper insurance coverage. Never start an arbitrage business without landlord approval and understanding of local laws.

How much does it cost to start rental arbitrage?

Startup costs for rental arbitrage usually include a security deposit, first month's rent, furnishing, photography, initial supplies, licensing, and reserves. The total can vary widely by property size, rent level, furnishing quality, and local permit requirements.

What's a good profit margin for rental arbitrage?

Many arbitrage operators target at least a 20% net margin, but the right threshold depends on lease risk, seasonality, regulation, and cash reserves. Thin margins leave little cushion for slow months, repairs, or unexpected vacancies.
