Wholesale Real Estate Calculator: How to Run the Numbers

Why Numbers Are Everything in Wholesaling

Real estate wholesaling means finding undervalued properties, getting them under contract at a low price, and assigning that contract to an end buyer (usually a rehabber) for a fee. Your profit is the spread between what you pay and what your buyer pays.

The problem: your end buyer is running their own numbers. If your deal doesn't work for them at the price you're assigning it, there is no deal. That means you need to calculate the numbers from their perspective first — then work backward to find your maximum entry price.

The Wholesale MAO Formula

The core formula for wholesale deal analysis is a modified version of the standard MAO formula:

Wholesaler MAO = (ARV × 70%) − Estimated Repairs − Assignment Fee

Where:

• ARV = After Repair Value (what the property will sell for after renovation)
• 70% = Standard threshold for rehabber buyers (their maximum price)
• Estimated Repairs = What your buyer will need to spend on rehab
• Assignment Fee = Your profit for putting the deal together

Step-by-Step Example

Let's run a real example:

• ARV: $185,000 (based on comparable renovated sales nearby)
• Estimated Repairs: $28,000 (cosmetic + kitchen update)
• Your Target Assignment Fee: $8,000

Buyer's Maximum Price = ($185,000 × 0.70) − $28,000 = $129,500 − $28,000 = $101,500

Your MAO = $101,500 − $8,000 = $93,500

To make $8,000 on this deal, you need to get the property under contract for $93,500 or less, then assign it to your buyer for $101,500.

How to Determine Your Buyer's Repair Estimate

You're estimating rehab costs from your buyer's perspective — not your own. This means estimating what a professional rehabber will pay in your local market for the scope of work required.

Practical approaches:

• Build a scope checklist: Walk or analyze the property photo by photo and categorize each repair (roof, HVAC, kitchen, baths, flooring, paint, etc.)
• Use regional cost benchmarks: Kitchen rehab, bath rehab, and flooring costs vary significantly by market. Know your local labor rates.
• Add a contingency: Add 10–15% above your itemized estimate. Buyers who discover your estimate was $10K low will not close — or will renegotiate aggressively.
• Use AI tools for remote deals: Our AI Rehab Cost Estimator can analyze listing photos and generate a line-item estimate, useful when you can't visit a property yourself.

Understanding ARV for Wholesale Deals

ARV estimation is the highest-risk part of wholesale analysis. If your ARV is inflated, your buyer won't close and you'll have wasted their time and yours.

Pull 3–5 comparable sales that:

• Sold within the last 3–6 months
• Are within a half-mile radius (tighter in dense urban areas)
• Have similar square footage (within 150–200 sq ft)
• Have the same or similar bed/bath count
• Were renovated to a similar finish level as your planned rehab

Use the lower end of the comp range for your ARV. This keeps your buyer comfortable and your deal credible. Use our ARV Calculator to pull and analyze comps automatically.

Adjusting Your Assignment Fee Based on Deal Size

Assignment fees in wholesale deals aren't one-size-fits-all. A realistic fee structure:

• ARV under $100,000: $3,000–$6,000 assignment fee
• ARV $100,000–$200,000: $6,000–$12,000
• ARV $200,000–$350,000: $10,000–$20,000
• ARV $350,000+: $15,000–$30,000+

Buyers know these benchmarks. Trying to take $25,000 on a $150,000 ARV deal will make buyers suspicious and resistant. Reasonable fees get deals closed.

The Spreadsheet vs. Calculator Approach

Many wholesalers start with a custom spreadsheet. The problem: spreadsheets require you to build and maintain them, and errors compound silently. A purpose-built MAO calculator gives you:

• Instant MAO calculation with adjustable multiplier
• Deal scenario modeling (change ARV or repairs, see MAO update instantly)
• Shareable results for your buyer conversations
• No formula errors

When you're evaluating 20–50 leads per month, speed and accuracy matter. The faster you can say "yes, dig deeper" or "no, move on," the more deals you can process with the same time investment.

Common Mistakes in Wholesale Deal Analysis

Inflating ARV to Make a Deal Work

This is the #1 mistake new wholesalers make. If the numbers only work with an optimistic ARV, they don't work. Your buyer will run their own comps and see through it.

Underestimating Repairs

A conservative repair estimate protects your buyer's margin. An aggressive estimate leads to failed closings, burned relationships, and a reputation for bringing bad deals.

Not Knowing Your Buyer's Criteria

Different buyers have different return requirements. Some need 20% profit. Some are fine with 12–15% on safe markets. Know what your active buyers need before you underwrite a deal for them.

Forgetting Your Own Costs

As the wholesaler, you also have closing costs on the A-to-B transaction and any marketing costs that got you the lead. Factor these in when deciding whether the assignment fee justifies the effort.

Running the Numbers Is a Competitive Advantage

Most wholesalers who fail do so because they bring their buyers deals that don't pencil. The ones who build reputations as reliable deal sources are the ones whose math is always clean and conservative.

Get the ARV right. Estimate repairs honestly. Leave room for your buyer to profit. Price your assignment fee fairly. Do that consistently and you'll have buyers who call you — not the other way around.
