What is Fix and Flip Deal Analysis?

Fix and flip deal analysis is the process of evaluating a potential property investment to determine if it will be profitable. It involves calculating several key metrics: the property's value after renovations (ARV), the cost of those renovations, all financing and holding costs, and ultimately, your expected profit and return on investment.

Professional house flippers analyze dozens or even hundreds of deals before making an offer. They use systematic analysis to quickly identify which properties are worth pursuing and which to pass on. The goal is simple: buy properties below market value, renovate them efficiently, and sell for a profit.

The analysis process helps you answer three critical questions:

• What is the maximum I should pay for this property?
• How much profit can I realistically expect?
• What is my return on investment and is it worth my time and capital?

Step 1: Calculate the After Repair Value (ARV)

The After Repair Value (ARV) is the estimated market value of the property after all renovations are complete. This is the cornerstone of your entire analysis—get it wrong, and everything else falls apart.

Finding Comparable Sales (Comps)

To determine ARV, you need to find recently sold properties that are similar to what your property will be after renovation. Here are the criteria professional appraisers use:

Find 3-5 comparable sales and calculate the average price per square foot. Then multiply by your property's square footage to get a baseline ARV. Make adjustments for significant differences like extra bathrooms (+$5,000-10,000), garage vs. no garage (+$10,000-20,000), or lot size variations.

Use our ARV Calculator to input your comparable sales and get an accurate after repair value estimate.

Step 2: Estimate Rehab Costs

Accurate rehab cost estimation separates successful flippers from those who lose money. The key is developing a systematic approach that accounts for all renovation categories.

Cost Per Square Foot Method

For quick initial analysis, use these price-per-square-foot benchmarks:

Line Item Budgeting

For more accurate estimates, create a line-item budget covering each renovation category:

• Kitchen: $15,000-$40,000 (cabinets, counters, appliances)
• Bathrooms: $8,000-$20,000 each
• Flooring: $3-$8 per square foot installed
• Paint: $2-$4 per square foot (interior and exterior)
• Roof: $8,000-$15,000 for full replacement
• HVAC: $5,000-$12,000 for new system
• Windows: $400-$800 per window installed
• Landscaping: $2,000-$5,000 for curb appeal

Always add a 10-15% contingency for unexpected issues. Every rehab uncovers surprises—water damage behind walls, outdated wiring, or permit requirements.

Use our Rehab Cost Estimator to build a detailed renovation budget.

Step 3: Calculate Your Maximum Allowable Offer (MAO)

The Maximum Allowable Offer (MAO) is the highest price you should pay for a property while still maintaining an acceptable profit margin. Most investors use the 70% Rule as their starting point.

Example Calculation

Let's say you're analyzing a property with an ARV of $300,000 and estimated rehab costs of $45,000:

When to Adjust the 70% Rule

The 70% rule is a guideline, not a law. Adjust based on market conditions:

• Hot markets: You may need to go to 75-80% to win deals (accept lower margins)
• Slow markets: Stick to 65-70% to account for longer holding periods
• Higher price points: Luxury homes ($500K+) may work at 75% due to larger absolute profits
• Quick flips: Cosmetic-only rehabs with fast turnaround may allow 75%

Use our 70% Rule Calculator or MAO Calculator to quickly determine your maximum offer.

Step 4: Determine Financing and Holding Costs

Financing costs can make or break a flip. Most investors use hard money loans for speed, but these come with higher costs that must be carefully calculated.

Hard Money Loan Costs

Monthly Holding Costs

Every month you own the property costs money. Budget for these recurring expenses:

• Loan interest: Principal × Interest Rate ÷ 12
• Property taxes: Annual taxes ÷ 12
• Insurance: Vacancy/builder's risk policy ($100-200/month)
• Utilities: Electric, water, gas ($150-300/month)
• Maintenance: Lawn care, security, etc. ($50-100/month)

Use our Hard Money Calculator and Holding Cost Calculator to model your financing costs.

Step 5: Calculate Total Profit and ROI

Now bring everything together to determine your expected profit and return on investment.

Key Metrics to Calculate

• Net Profit: Your actual dollar profit after all expenses
• ROI (Return on Investment): Net Profit ÷ Total Investment × 100
• Cash-on-Cash Return: Net Profit ÷ Cash Out of Pocket × 100
• Annualized ROI: ROI × (12 ÷ Months Held) - useful for comparing flips of different lengths
