Real House Flip Case Study: Purchase Price, Rehab Budget, Sale Price, and Profit

A house flip looks simple from the outside. Buy a distressed property, renovate it, sell it for more, and keep the difference. But anyone who has managed a real flip knows the profit is never just the sale price minus the purchase price and rehab budget.

The true profit depends on acquisition costs, financing costs, holding costs, renovation overruns, permits, utilities, insurance, selling costs, agent commissions, buyer concessions, and timeline. A deal that appears to have a $70,000 spread can easily produce far less once every cost is counted.

That is why case studies are so useful. They force investors to look beyond the headline numbers and study the actual mechanics of a flip.

The case study below uses a realistic single-family house flip example. The numbers are designed to show how a typical moderate renovation might perform when purchased correctly, managed carefully, and sold into a retail market. Every market is different, and actual results will vary, but the structure of the analysis is what matters.

From a consultant’s perspective, the lesson is simple: profit is not created at sale. Profit is protected through disciplined buying, budgeting, project management, and exit planning.

Property Overview

For this case study, assume the property is a three-bedroom, two-bath single-family home in a working-to-middle-income suburban neighborhood. The home was built in the 1980s and had solid bones, but it was cosmetically dated and had several deferred-maintenance issues.

The property was not a full gut renovation. It did not require foundation repair, major structural work, or a full layout redesign. That is important. This was a moderate flip, not a heavy rehab.

The house needed:

Interior paint
New flooring
Kitchen update
Bathroom updates
Lighting replacement
Minor electrical repairs
Plumbing fixture replacements
HVAC service
Roof repairs
Exterior cleanup
Landscaping
Appliances
Final cleaning and staging

The target buyer was an owner-occupant looking for a move-in-ready home. Comparable renovated homes in the neighborhood were selling between $310,000 and $330,000, depending on finish quality, lot condition, and days on market.

The investor’s goal was to buy below market, complete a clean but not overbuilt renovation, and resell near the upper-middle range of the comps.

Purchase Price

The property was purchased for $210,000.

This price was not chosen randomly. The investor estimated the after-repair value at approximately $325,000 and expected the renovation to cost around $45,000. After adding holding costs, selling costs, financing costs, and a target profit, the maximum allowable offer was around $212,000.

The investor negotiated slightly below that number and secured the property at $210,000.

This is the first lesson. The purchase price must be based on the exit value and total project cost, not on the seller’s asking price or the investor’s excitement.

A simplified underwriting model looked like this:

Estimated resale value: $325,000
Estimated rehab: $45,000
Estimated selling costs: $25,000
Estimated holding and financing costs: $15,000
Target profit: $30,000
Maximum purchase price: $210,000

Based on those assumptions, the deal made sense. It had enough margin to absorb some surprises, but it was not overly forgiving. The investor needed to manage the renovation carefully.

Acquisition Costs

The purchase price was $210,000, but the total acquisition cost was higher. This is where many beginners undercount the deal.

The investor paid closing costs, title fees, recording fees, insurance setup costs, and lender-related fees. Some costs vary by state, county, lender, and transaction type, but they must always be included in the analysis.

For this case study, acquisition-related costs were:

Purchase price: $210,000
Buyer closing costs: $4,200
Lender fees and points: $4,800
Initial insurance premium: $1,200
Total acquisition cost: $220,200

The investor used short-term financing, so the lender fees mattered. A cash buyer may avoid some financing costs, but cash has its own opportunity cost. Hard money and private money can help investors move quickly, but they reduce the net profit.

A consultant would never analyze a flip using purchase price alone. The real starting cost is the purchase price plus all acquisition expenses required to control the property.

Original Rehab Budget

The original rehab budget was $45,000.

The scope of work was designed to match neighborhood expectations. The investor did not install luxury finishes, custom cabinetry, or high-end appliances because the local comps did not justify that level of spending.

The original rehab budget looked like this:

Kitchen: $13,500
Bathrooms: $8,000
Flooring: $7,500
Interior paint and drywall repair: $5,500
Lighting and electrical repairs: $3,000
Plumbing fixtures and minor repairs: $2,500
Roof repairs and exterior work: $2,500
Landscaping and curb appeal: $1,500
Cleaning and punch list: $1,000
Total planned rehab: $45,000

This budget was realistic but tight. The investor included a contingency outside the base rehab number because older homes often reveal small surprises once demolition begins.

The renovation strategy was not to make the home the nicest property in the neighborhood. It was to make it competitive with the best recent renovated comps without overspending.

Actual Rehab Costs

The final rehab cost came in at $49,750, which was $4,750 over the original budget.

The increase came from three areas.

First, the subfloor in one bathroom had water damage after the old flooring was removed. Repairing it added cost.

Second, the electrical panel needed additional work to satisfy inspection and improve buyer confidence.

Third, landscaping required more cleanup than expected because the backyard had drainage debris and overgrowth that affected presentation.

The actual rehab costs were:

Kitchen: $13,900
Bathrooms: $9,600
Flooring: $7,700
Interior paint and drywall repair: $5,800
Lighting and electrical repairs: $4,400
Plumbing fixtures and minor repairs: $2,650
Roof repairs and exterior work: $2,600
Landscaping and curb appeal: $2,100
Cleaning and punch list: $1,000
Total actual rehab: $49,750

The overage was manageable because the original deal included enough margin. This is why contingency planning matters. A flip with no room for surprises is not a safe flip.

The investor also made the right decision by spending on functional issues rather than cosmetic extras. Repairing the bathroom subfloor and electrical items helped reduce buyer inspection objections later.

Renovation Timeline

The original renovation timeline was eight weeks. The actual renovation took ten weeks.

The delay came from contractor scheduling and countertop installation. Cabinets were installed on time, but countertop measurement and fabrication added several days. A bathroom repair also delayed flooring installation in that section of the home.

The timeline looked like this:

Week 1: Cleanout and demolition
Week 2: Rough repairs and material ordering
Weeks 3–4: Bathrooms, electrical, plumbing, drywall
Weeks 5–6: Kitchen cabinets, paint, flooring preparation
Week 7: Flooring and trim
Week 8: Countertops, fixtures, appliances
Week 9: Exterior, landscaping, punch list
Week 10: Final cleaning, staging, photography

The two-week delay increased holding costs, but it did not derail the project.

The lesson is that timeline estimates should include buffer. Renovations rarely move perfectly. Materials, inspections, weather, and contractor availability can all affect the schedule.

A consultant would rather see a realistic ten-week schedule than an optimistic six-week schedule that fails immediately.

Holding Costs

Holding costs are the costs of owning the property during the project. They continue whether work is happening or not.

For this case study, holding costs included:

Loan interest
Property taxes
Insurance
Utilities
Lawn care
Security and maintenance
Miscellaneous property expenses

The total holding period from purchase closing to resale closing was about five months. The renovation took ten weeks, the property was prepared and listed, it went under contract after 18 days, and the buyer closing took about 35 days.

Holding costs were:

Loan interest: $10,250
Property taxes: $1,850
Insurance: $1,400
Utilities: $950
Lawn care and maintenance: $600
Miscellaneous property costs: $450
Total holding costs: $15,500

This is where many new investors underestimate the project. They may budget for the renovation but forget that the property costs money every month.

Time is not neutral in a flip. Time is an expense.

Sale Price

The property was listed at $329,900.

The listing price was based on renovated comps, current active competition, and the quality of the finished product. The investor and listing agent decided not to overprice aggressively because the market was price-sensitive and the goal was to create strong early activity.

The property received steady showings during the first week and one strong offer during the second week. After negotiation, the final contract price was $326,000.

This was slightly above the original estimated ARV of $325,000, which was a positive result. However, the investor still had to account for seller costs, buyer requests, commissions, and closing expenses.

The sale price alone did not represent the profit.

Selling Costs

Selling costs included agent commissions, seller closing costs, staging, photography, buyer credits, and minor inspection-related repairs.

The selling costs were:

Agent commissions: $19,560
Seller closing costs and title fees: $3,900
Staging and photography: $1,500
Buyer repair credit: $2,000
Home warranty: $600
Final touch-ups before closing: $700
Total selling costs: $28,260

The buyer repair credit came after inspection. The buyer requested several minor repairs, including a plumbing adjustment, an outlet correction, and HVAC servicing documentation. Instead of delaying closing with multiple small repairs, the investor negotiated a $2,000 credit.

This was a practical decision. Sometimes a credit is better than sending contractors back into the property and risking delays.

Selling costs are often one of the largest deductions from gross profit. Flippers must include them before buying, not after listing.

Gross Profit vs. Net Profit

On the surface, the flip looks like this:

Sale price: $326,000
Purchase price: $210,000
Difference: $116,000

A beginner might see that $116,000 spread and assume the investor made a huge profit. That is incorrect.

Now subtract the actual costs:

Purchase price: $210,000
Acquisition costs: $10,200
Actual rehab: $49,750
Holding costs: $15,500
Selling costs: $28,260
Total project cost: $313,710

Sale price: $326,000
Total project cost: $313,710
Net profit before income taxes: $12,290

That is a very different number from the original $116,000 spread.

However, this does not mean the deal was a failure. It means the final margin was thinner than expected because financing, holding costs, selling costs, and rehab overages consumed much of the spread.

The investor made money, but not enough to justify the risk comfortably. From a consultant’s perspective, this case study shows a deal that worked, but barely.

Why the Profit Was Lower Than Expected

The original underwriting estimated a target profit of about $30,000. The actual pre-tax profit was $12,290.

The main differences were:

Rehab ran $4,750 over budget.
Holding costs were slightly higher because of the longer timeline.
Selling costs were higher than expected due to buyer credit and commission math.
The property sold close to ARV but not high enough to absorb all added costs.
The original margin was not wide enough for multiple small misses.

No single issue destroyed the deal. Instead, several normal project realities reduced the profit.

This is common in house flipping. A project does not need a disaster to underperform. A few thousand dollars here and there can change the outcome.

This is why conservative underwriting matters.

What Went Right

Even though the profit was thinner than expected, several things went well.

The investor bought near the correct maximum offer. The property was not dramatically overpriced at acquisition.

The renovation scope matched the neighborhood. The investor did not waste money on luxury finishes that buyers would not pay for.

The project was completed with only a modest delay. A two-week delay is not ideal, but it is manageable.

The final sale price supported the original ARV estimate. This means the resale valuation was reasonably accurate.

The property went under contract within a reasonable time. Pricing and presentation were effective.

The buyer inspection did not create major problems because the investor addressed important repairs during renovation.

These positives show that the project was managed reasonably well. The issue was not poor execution. The issue was that the deal needed a stronger margin from the start.

What Could Have Been Improved

The most important improvement would have been buying at a lower price.

If the investor had purchased the property for $200,000 instead of $210,000, the profit would have increased by $10,000. That would have moved the deal from thin to more acceptable.

The second improvement would have been a larger rehab contingency. The overage was not extreme, but the original budget was tight.

The third improvement would have been a more detailed pre-purchase inspection of the bathrooms and electrical system. Some of the added costs may have been identified earlier.

The fourth improvement would have been negotiating seller credits or a price reduction after due diligence. If inspection findings supported a lower price before closing, the investor should have used that leverage.

The fifth improvement would have been reducing financing costs, either through cheaper capital or faster execution. In a short-margin deal, financing cost matters.

A consultant would summarize the lesson this way: the project was operationally acceptable, but the acquisition margin was not strong enough.

Return on Investment

Profit should be measured against capital invested and risk taken.

Assume the investor had approximately $55,000 of personal cash into the deal at different points, including down payment, closing costs, initial renovation expenses, draw gaps, and reserves.

With a pre-tax profit of $12,290, the cash-on-cash return was approximately:

$12,290 ÷ $55,000 = 22.3%

At first glance, that return may look attractive. But the project took about five months, involved active management, and carried execution risk. Also, taxes still need to be paid from the profit.

This is why return metrics should be interpreted carefully. A percentage return can look good while the actual dollar profit is modest.

For a house flipping business, both matter. You need percentage return to evaluate efficiency and dollar profit to justify effort and risk.

Lessons for New Flippers

This case study offers several important lessons.

First, do not rely on the purchase-to-sale spread. The real profit comes after all costs.

Second, include acquisition, holding, financing, and selling expenses before making the offer.

Third, build contingency into the rehab budget. Small surprises are normal.

Fourth, timeline affects profit. Every extra week costs money.

Fifth, ARV accuracy matters, but even a correct ARV does not guarantee strong profit if the purchase price is too high.

Sixth, buyer credits and selling costs can materially reduce the final number.

Seventh, a profitable flip can still be a weak deal if the risk-adjusted return is not strong enough.

The biggest lesson is that the purchase price controls the deal more than almost anything else. Renovation management matters, but you cannot always renovate your way out of overpaying.

A Better Target for This Deal

Looking back, a stronger version of this deal would have looked like this:

Sale price: $326,000
Total costs excluding purchase price: $103,710
Target profit: $30,000
Maximum purchase price: $192,290

This means that if the investor wanted a $30,000 profit based on the actual cost structure, the purchase price needed to be closer to $192,000, not $210,000.

That does not mean the investor made a foolish decision. It means the actual cost stack proved the original offer was too aggressive.

This is the value of case studies. They show the difference between theoretical underwriting and real project performance.

Final Thoughts

A real house flip case study is useful because it reveals what headline numbers hide. A property bought for $210,000 and sold for $326,000 sounds like a major win. But after acquisition costs, rehab costs, holding costs, financing costs, selling costs, and buyer credits, the actual pre-tax profit was $12,290.

That is still a profit, but it is not the profit many beginners would expect.

The case study reinforces the most important rule in house flipping: calculate every cost before you buy. The purchase price, rehab budget, sale price, and profit are connected. If one number is wrong, the entire deal changes.

A successful flipper does not just ask, “Can I sell this for more than I paid?” A successful flipper asks, “After every real cost, delay, fee, credit, and risk, does this deal still produce enough profit to be worth doing?”

That is the mindset that separates casual flippers from disciplined investors.
