I Analyzed a $900k Car Wash for Sale: Here's What It's Worth

One of the new services I'm offering at SmartHelping is a deal screener for buyers of $500k to $10M small businesses. I'll walk through a potential deal with buyers and run all the data through a template like you see below. Note, in the video there are many variables and parts that I can't complete unless it was an actually real-world engagement where there was more due diligence available from the seller and NDAs were signed. However, you can see the detailed process.

Here's a pre-built financial model for car wash startups to work from and here are more templates for the automotive industry in general.

In the above deal, there was $325k of gross revenue and $180k in annual adjusted net income. The listing also labels that $180k as EBITDA so if I were actually doing pre-diligence work on this it is important to understand what the seller's adjustments are as that can dramatically effect the potential valuation. The real estate was included in the purchase.

It was labeled as an 'absentee ownership' situation (the owner was not involved in doing any work that involves a salary) so the $180k figure may be close to the actual cash the buyer can expect as a return per year if nothing changes. In the video I put in some fictional 'earnings adjustments' to show how that may effect the deal metrics.

At a purchase price of $900k, that means you are buying in at roughly a 2.76x multiple of revenue and 5x EBITDA. Without knowing much else as far as required renovations / repairs or other things that could raise initial costs or effect ongoing operations, the purchase price needs to come down to $700/800k. 

That price suggestion is only my opinion and some things that may make the original purchase price make sense is if the buyer thinks they can raise sales and EBITDA substantially over a few years. Big factors include the feasibility of growing memberships, improving equipment / parking lot / features / POS upgrades / marketing and so forth. If you can double sales, that means your stabilized going-in revenue multiple may get down to 1.38x instead of 2.76x.

At the end of the day you want to know the hassle you are taking on, the expected amount of time it will take to pay off the initial investment with earnings, and if sales are trending in the right direction or there is clear opportunity to be able to make that happen.

The risk is in the leverage. If you only put down 20/25%, it could mean larger returns on the actual invested capital, but if operations are slow to start and your debt coverage is getting close to 1 or negative, there is risk of losing it. That just speaks to the durability of revenues and any unforeseen costs.

In the analyze process, I also look at many qualitative and risk factors that are more of a judgement call rather than directly related to the numbers. This gives a more comprehensive view of the target business for the buyer as they try to get a feel for the potential acquisition.

In my analysis process, there will be an overall deal score, and individual deal scores for:
  • Financial Performance
  • Valuation & Returns
  • Debt & Downside Protection
  • Revenue / Customer Quality
  • Operational Quality
  • Management / Owner Dependence
  • Market & Competitive Position
  • Deal / Diligence Risk

Solar Farm Unit Economics: What Matters Before You Scale

A solar farm is economically attractive when the risk-adjusted, after-tax value of each delivered MWh exceeds the fully loaded cost of producing and delivering it—and when the resulting return justifies the equity capital tied up for several years.

How to Measure the Quality of Revenue: Financial Modeling Concepts

Modeling expected gross profit or contribution margin tells you whether revenue growth is economically valuable, not merely whether revenue is increasing.

Example Scenario: Your First 180 Days as a Founder to be Successful

This is an example scenario of what the first 180 days might look like for someone trying to build a startup in a fictional business as the founder of a recycling company that targets waste from different delivery services (Amazon and so forth). Mainly from multi-family apartment buildings, student housing, condos, and the like. I thought this ideas was interesting as some data shows 7 out of 10 cardboard boxes end up in the trash instead of recycled.

How Complex Should a Financial Model Be to Be Effective?

A financial model only needs to be as complex as the decision it supports. An effective model is not the one with the most tabs, formulas, or assumptions. It is the one that helps someone make a better decision with reasonable confidence.

Financial Models and Reality: When the Map Matches the Territory

Financial modeling is a structured attempt to describe a messy real-world financial situation using assumptions, formulas, scenarios, and logic. It can be very useful, but it is never the same thing as reality. A good model is more like a map than the territory: it can help you navigate, but it leaves things out.

Local Supply and Demand: Self-storage Deal Analysis

A key concept is local supply-and-demand underwriting: before trusting the purchase price, cap rate, or projected returns, ask whether the facility’s trade area actually has enough unmet demand to support the rents and occupancy you are assuming.

Financial Modeling Concepts: Equipment Rental

Think of an equipment rental company as an asset-yield business: you buy or finance equipment, rent it out repeatedly, earn ancillary fees, maintain the fleet, and eventually sell used equipment. The best financial model is therefore not a simple “revenue grows X%” model. It should be a fleet model where revenue, costs, depreciation, capex, debt, and cash flow all flow from the equipment base.

The most important lever in hotel underwriting is RevPAR, but the most powerful sub-lever is usually ADR, not occupancy.

A Good Financial Model Enables Many Things

A financial model is a spreadsheet-based tool that helps you estimate how a business could perform financially under different assumptions. For a startup, it is especially useful because the future is uncertain and you need to understand how sales, costs, hiring, pricing, funding, and growth affect cash flow.

Three Primary Users of Startup Financial Models

So who uses financial models? and specifically ones made for startups? Let's see...

Customer Acquisition Theory - How Retention Patterns Vary Depending on Method of Acquisition

This is one for the SaaS people, but also relevant to any business with recurring revenue services. Note, you can enter data in various SaaS financial models to see how certain assumptions affect LTV and the bottom line. Let's discuss how the way a customer is acquired can result in different retention patterns.

Basics of Starting or Operating Your Own Trucking Company vs Starting a FedEx Fleet

Assuming U.S. operations, there are really three businesses to compare:

  1. Your own for-hire trucking company hauling freight for shippers and brokers.
  2. FedEx linehaul, using tractors to move FedEx-owned trailers between terminals.
  3. FedEx pickup and delivery, or P&D, using vans and step trucks for local package routes.

FedEx linehaul is the closest comparison to a traditional trucking company. FedEx P&D is closer to operating a large local delivery and staffing business.

Financial Modeling for SaaS Businesses: Retention Curves

We are focusing on retention-curve shapes rather than just benchmark percentages, then map common patterns across SaaS types like SMB self-serve, enterprise, vertical, usage-based, and freemium/PLG.

Cash Flows and Securitization

 An interesting aspect of modeling securitization deals is that the model is less about forecasting a single “correct” outcome and more about understanding how cash flows move through the structure under different stresses.

This is an in-home safety business model template that can be used for financial planning. The core business involves making senior citizen homes safer so they can live alone longer. The primary revenue streams are initial one-time audit, retrofit, and ongoing services. The financial model below was built to handle initial startup and then scaled-up operations.

Utilizing Debt Refinancing Strategies in a Business Turnaround

In a business turnaround, fixing the company’s operations is only half the battle. The company may still have a serious debt problem: a loan coming due too soon, interest payments that consume too much cash, covenant violations, or a lender that no longer trusts the business. In that situation, management often tries to refinance the debt. This usually means using a new loan to pay off an existing loan, then operating under a new repayment schedule that gives the company more time and flexibility.

Multifamily Investing Template Deep Dive: Let's Start with Rent Roll

A rent roll is one of the best places to analyze value-add potential because it shows the deal at the unit level, where the value-add plan actually happens.

A T12 tells you what the property produced historically. A broker pro forma tells you what someone hopes it can produce. The rent roll sits between those two: it shows who is paying what, for which unit, under which lease, and when that rent can realistically change.

Hotels Are Valued Differently Than Traditional Real Estate

Hotels are valued differently than most traditional real estate assets because they are both real estate investments and operating businesses similar to assisted living facilities. While properties like apartments / multifamily, office buildings, or retail centers are typically valued based on long-term lease income, hotels generate revenue one night at a time. This makes hotel valuation more dynamic, more operationally sensitive, and often more dependent on market conditions.

Maximizing Net Rental Income, Not Occupancy or Rent Amount

For many long-term landlords, the best risk-adjusted strategy is slightly below the absolute top of market, because it reduces vacancy, improves tenant selection, and lowers turnover.

To calculate market rent, the core reasoning is: first define exactly what you are pricing, then compare it to the most similar rental evidence available.

Personal Wealth Builder Template

I normally don't do a ton of personal finance stuff as most of the work and clients I deal with are of the commercial nature. However, that doesn't mean my spreadsheet skills are lost on helping the individual. This is a great discipline and wealth building helper that gives anyone a savings and investment structure for the long term.

Financial Model Template for Loan Brokerage (or deal advisor)

I've done a few financial models for loan brokerage clients, and I've decided to build a public-facing custom version that I think fits the most types of scenarios and strategies. This includes three main types of loans, and the fourth channel is deal volume for investment banking / capital advisory strategies. They are similar but have some differences in logic that are relevant.

Preferred Return - Investor Thresholds - Dynamic Capital Repayment

I've done about a dozen joint venture waterfall frameworks and this most recent one is different enough from the rest that it deserves its own version. The way capital is repaid and the pref. works is unique to any other template I've done.

Advanced Warehouse Fulfillment Financial Model (Pallet & Cubic Foot Versions)

I've done more critical research in warehouse logistics than I thought I'd ever do in my life after building this financial model. We are talking about 3rd party logistics (3PL). The template does a great job at capturing seasonality, warehouse sizing economics, activity-driven revenues / expenses, and showing a financial projection based on bottom-up assumptions.

Financial Model Sensitivity Analysis: LCOE ($/MWh)

LCOE is a way to measure the total lifetime cost to produce energy by a power plant, denominated in MWh. It could be solar, wind, nuclear, or what have you. The calculation stands for levelized cost of energy and the idea is to calculate the present value of all costs against the present value of all future energy production. The goal is to find out how much it cost to produce a MWh of energy in today's dollars.
