Flipping houses isn’t just about finding something ugly and turning it pretty. It’s about turning capital into profit, predictably, repeatedly, and with as little risk as possible. That’s why experienced flippers lean on proven deal analysis frameworks before ever swinging a hammer.

But if you’re new to the game, it’s easy to get lost in the excitement and emotion of a “great opportunity.” This is how bad flips happen.

This guide gives first-time flippers a step-by-step framework to evaluate flip deals like a pro, from the moment you see a property to the moment you make an offer.

Why a Deal Analysis Framework Matters

Flipping is capital-intensive. You’re putting money on the line, often someone else’s. You can’t afford to guess on margins or assume the rehab will “probably be fine.”

Here’s what’s at stake if you don’t analyze deals properly:

• Overpaying for the property

• Underestimating rehab costs

• Overestimating ARV (after-repair value)

• Choosing the wrong neighborhood

• Missing red flags that kill resale potential

That’s why the pros have checklists, formulas, and frameworks. Let’s walk through the exact ones you need.

The 5-Part Deal Analysis Framework

There are five major elements every flipper must evaluate:

1. Acquisition price

2. Rehab cost

3. After-repair value (ARV)

4. Holding and transaction costs

5. Profit margin/spread

Let’s break these down in detail.

1. Estimating the Right Purchase Price

The golden rule of flipping is: You make money when you buy, not when you sell.

That means your purchase price has to be low enough to allow for repairs, fees, and profit. Most flippers use a variation of the MAO (Maximum Allowable Offer) formula:

MAO = (ARV x 70%) – Estimated Repairs

The “70% rule” is a starting point. It builds in room for closing costs, agent commissions, and profit. But depending on your market, you may want to adjust that to 75% or even 80%, especially in appreciating areas.

Example:
If the ARV is $300,000 and repairs are $40,000:

70% of ARV = $210,000
Subtract $40,000 rehab = $170,000 MAO

That’s the most you should offer. Ideally, you buy it for even less.

2. Accurately Estimating Rehab Costs

This is where most first-time flippers lose money, underestimating renovation costs.

Here’s a simple 3-tier rehab cost model to use if you don’t have a contractor yet:

• Cosmetic rehab: $20–30/sqft (paint, flooring, fixtures)

• Moderate rehab: $30–50/sqft (kitchens, baths, HVAC)

• Heavy/full gut rehab: $50–100+/sqft (foundation, roof, structural)

You’ll want to walk the property (or have a trusted GC do it) and note:

• Roof age and condition

• HVAC, electrical, and plumbing systems

• Foundation cracks or sloping

• Kitchen and bath status

• Windows, doors, flooring, drywall

Pro tip: Add a 10–20% contingency buffer for surprises. First-timers should budget higher rather than tighter.

3. Determining Accurate ARV

ARV is what you believe the house will sell for after repairs. This number is crucial; it determines your potential upside.

To estimate ARV:

• Find comps (comparable sales) within 0.5 miles

• Only use comps sold in the last 3–6 months

• Match property type, size, bed/bath count, lot size

• Ideally, use homes that were recently renovated

If the comps aren’t flipped homes, you may overestimate your ARV. Use tools like:

• Zillow (Sold listings)

• Redfin

• MLS access (via your agent)

• PropStream or Privy

Also, walk the comps if possible. Photos don’t tell the whole story.

4. Accounting for Hidden Costs

Flipping isn’t just buying and renovating; it’s also holding, financing, and selling.

Here are the most common non-rehab costs to factor in:

Holding Costs:

• Property taxes

• Utilities

• Insurance

• HOA fees (if any)

Financing Costs:

• Hard money loan interest (10–12% annually)

• Points at closing (1–3% of loan amount)

• Origination fees

Selling Costs:

• Realtor commission (usually 5–6%)

• Closing costs (~1–2%)

• Staging/cleaning/photos

Total nonrehab costs can eat up 10–15% of ARV if not managed properly.

5. Calculating Profit and Safety Margin

Once you’ve estimated all the numbers, plug them into a simple flip pro forma:

• ARV: $300,000

• Rehab: $40,000Holding + Transaction Costs: $30,000

• Purchase Price: $170,000

• Total Invested: $240,000

• Projected Profit: $60,000 (20% margin)

That’s a healthy spread.

Warning sign: If your projected profit is less than 15%, or your buffer is razor-thin, walk away or renegotiate.

Bonus Framework: The 4 “Filter First” Criteria

Before even running numbers, apply these quick filters to weed out the duds:

1. Neighborhood quality: B or C-class neighborhoods are ideal; avoid warzones and luxury zips.

2. Days on market: If it’s been sitting for 90+ days, something’s wrong, or it’s ripe for a discount.

3. Lot and layout: Avoid weird lot shapes, tiny bedrooms, and 1-bath layouts in 3-bed homes.

4. Resale ceiling: If the nicest home nearby only sold for $210K, your $300K ARV is fiction.

These filters save you time and effort before deep analysis.

Red Flags That Should Stop You Cold

Flippers lose money when they ignore red flags. Be ruthless. If you see these, pause or walk:

• Unpermitted additions or conversions

• Major foundation issues or structural movements

• No comps nearby or wildly inconsistent ARVs

• Sellers who refuse access or documentation

• Extremely low ceiling height in the basement or attic

• Bad neighbors, bad schools, or busy intersections

One deal won’t make or break you, but the wrong one can wipe you out.

Templates and Tools to Use

You don’t need to analyze every deal from scratch. Here are some resources:

Spreadsheets:

• Build a deal calculator that autogenerates MAO, ARV, and profit

• Use Google Sheets for quick collaboration

Apps and Tools:

• PropStream (property data + comps)

• Flipster (deal calculators + templates)

• Privy (automated deal finding and analysis)

• DealCheck (mobile-friendly property analysis tool)

Your team:

• A GC who gives you ballpark rehab estimates

• An investor-friendly agent to help with comps

• A mentor or peer to double-check your assumptions

You don’t have to do this alone, but you do need a system.

Practice Makes Profitable

The first few deals you analyze will feel slow and uncertain. That’s normal. But over time, you’ll spot patterns, pricing, and pitfalls fast.

Treat every deal like a rep at the gym:

• Run the numbersDoublecheck the comps

• Estimate rehab conservatively

• Build in buffers

• Protect your downside

And don’t fall in love with any one property. The right flip is a math problem, not a fairy tale.

If the numbers don’t work, next.
