How to Calculate Flip Property Profit in Chicago (2026 Guide)

Flipping houses in Chicago can be highly profitable—but only if you know your numbers before you buy.

Many new investors lose money because they underestimate costs or overestimate the value of a property. This guide will show you exactly how to calculate your profit so you can invest with confidence.

Why Calculating Profit Matters

Before buying any flip property, you need to answer one question:

Will this deal actually make money?

If you skip this step, you risk:

• Overpaying for the property
• Underestimating renovation costs
• Losing profit due to hidden expenses

Smart investors always run the numbers first.

Flip Property Profit Formula

$\text{Profit}=\text{ARV}-(\text{Purchase Price}+\text{Repair Costs}+\text{Holding Costs}+\text{Closing Costs})$

What Each Term Means:

• ARV (After Repair Value): Estimated value after renovation
• Purchase Price: What you pay for the property
• Repair Costs: Renovation and labor expenses
• Holding Costs: Taxes, utilities, insurance, loan interest
• Closing Costs: Fees when buying and selling

Step 1: Estimate the ARV (After Repair Value)

ARV is the most important number in your deal.

To estimate it:

• Look at recently sold homes in the same area
• Choose properties with similar size, condition, and features
• Focus on updated or renovated homes

In Chicago, neighborhood differences matter a lot, so always use local comps.

Step 2: Calculate Repair Costs Accurately

Many investors fail here.

Common rehab costs include:

• Kitchen and bathroom upgrades
• Flooring and paint
• Roofing or structural repairs
• Electrical and plumbing

👉 Always add a 10–20% buffer for unexpected expenses.

Step 3: Include Holding Costs

Holding costs are often ignored—but they can eat your profit.

These include:

• Property taxes
• Insurance
• Utilities
• Loan interest
• Maintenance

The longer you hold the property, the more you pay.

Step 4: Don’t Forget Closing Costs

You pay closing costs twice:

• When buying
• When selling

Typical costs:

• Agent commissions
• Title fees
• Transfer taxes

These can total 8%–10% of the sale price.

Step 5: Use the 70% Rule

The 70% rule helps you avoid bad deals.

Formula:

Maximum Purchase Price = (ARV × 70%) − Repair Costs

This gives you a safe buying range.

Example: Chicago Flip Deal

Let’s break it down:

• ARV: $420,000
• Purchase Price: $250,000
• Repair Costs: $60,000
• Holding Costs: $15,000
• Closing Costs: $10,000

Estimated Profit:

$420,000 − $335,000 = $85,000 profit

This is a strong deal by most investor standards.

Common Mistakes New Investors Make

Avoid these:

• Overestimating ARV
• Underestimating rehab costs
• Ignoring holding costs
• Skipping deal analysis
• Buying based on emotion

Successful investors rely on numbers—not guesses.
