Part One

Real Estate

Land, buildings, and site improvements valued through cap rates, comparable sales, and replacement cost analysis.

Part Two

Operations

Cash flow, subscriptions, car count, and efficiency valued through SDE multiples and industry benchmarks.

Car Wash Valuation: Two Assets, One Deal

If you own the real estate under your car wash, your business has two distinct values that need separate analysis. Typical multiples range from 3.0x to 5.0x SDE for operations, plus the real property value.

Two Valuations in One

A car wash that owns its real estate is fundamentally different from one that leases. When you own both, a buyer is acquiring two distinct assets: the income-producing business and the commercial property underneath it. These two assets are valued using completely different methodologies, and conflating them is one of the most common mistakes owners make when trying to estimate what their car wash is worth.

The business is valued on its earnings. Specifically, buyers look at Seller's Discretionary Earnings and apply a multiple that reflects the quality of those earnings: how predictable they are, how dependent they are on the owner, and how much growth potential exists. The real estate is valued independently, using cap rates, comparable property sales, and the replacement cost of the structures. A car wash property in a high-traffic corridor with excellent ingress and egress could be worth substantially more than the business it houses.

This distinction matters because it creates structural options in how you sell. You can sell everything together, sell the business and lease back the property, or in some cases sell the real estate separately. Each structure has different tax implications, different buyer pools, and different total value outcomes. Understanding the split is the first step in structuring a sale that maximizes your total return.

Real Estate vs. Business Value

Two separate analyses using different methodologies. Here's how each side of the valuation works.

Real Estate Valuation

Property, land, and improvements

Methodology

  • 1.Cap rate analysis (6-8% typical for car wash properties)
  • 2.Comparable property sales within 5-10 mile radius
  • 3.Replacement cost of structure, tunnels, and equipment pads

Key Factors

  • Traffic count on adjacent roads
  • Visibility and signage allowances
  • Ingress/egress patterns and stacking capacity
  • Environmental compliance (water, chemicals)
  • Lot size and expansion potential

Example

A 0.75-acre car wash property generating $90,000 in net rent equivalent on a 7% cap rate is worth approximately $1,285,000 as real estate alone.

Business Operations Valuation

Cash flow, subscriptions, and operations

Methodology

  • 1.SDE calculation with owner benefit add-backs
  • 2.Multiple based on revenue quality (3.0x - 5.0x)
  • 3.Subscription revenue analyzed separately at premium

Key Factors

  • Monthly subscriber count and retention rate
  • Average daily car count (weekday and weekend)
  • Revenue per car and package mix
  • Labor cost as percentage of revenue
  • Equipment age and capital expenditure needs

Example

An express car wash with $200,000 SDE, 600 active subscribers, and modern equipment might sell at 4.5x SDE = $900,000 for operations alone.

Combined Example

Real estate value ($1,285,000) + business operations ($900,000) = $2,185,000 total. This is why owner-operated car washes with owned real estate often sell for much more than people expect. The real property can represent 40-60% of the total deal value.

The Subscription Model Revolution

Unlimited wash memberships have fundamentally changed how car washes are valued. The shift from transactional to recurring revenue has created a new premium tier.

Customer RetentionNo lock-in85-90% monthly
Buyer Confidence LevelModerateHigh

At scale, a car wash with 500 subscribers at $30/month generates $180,000 annually in near-guaranteed revenue. That predictability is what drives the valuation premium.

Sale Structure Options

Owning the real estate gives you structural flexibility that leased operators don't have. Each approach has trade-offs.

Option

A

Sell Business + Real Estate Together

The simplest transaction. One buyer, one deal, one closing. The combined price typically exceeds what you'd get selling each separately because buyers pay a convenience premium for full control.

Advantages

  • -- Largest buyer pool (SBA eligible)
  • -- Simplest transaction to execute
  • -- Clean break for seller

Considerations

  • -- You give up the appreciating real estate asset
  • -- Higher total price limits some buyers
  • -- Larger tax event in a single year

Option

B

Sell Business + Lease Back Real Estate

Sell the car wash operations while retaining ownership of the property. The buyer operates under a long-term lease, and you receive both the sale proceeds and ongoing rental income. A popular strategy for owners approaching retirement who want passive income.

Advantages

  • -- Retain appreciating real estate asset
  • -- Ongoing passive rental income
  • -- Lower sale price widens buyer pool

Considerations

  • -- Tenant risk if buyer struggles
  • -- Ongoing landlord responsibilities
  • -- Some buyers won't consider leased sites

Option

C

Sell Real Estate + Keep Operating

Less common but viable in strong real estate markets. You sell the property to a real estate investor, negotiate a long-term lease for yourself, and continue running the business. This unlocks the real estate equity while keeping your income stream.

Advantages

  • -- Unlock trapped RE equity immediately
  • -- Keep operating the business you enjoy
  • -- RE investors offer competitive pricing

Considerations

  • -- You now have a landlord and lease terms
  • -- Lease cost reduces business SDE
  • -- Future business sale price may be lower
