Flipping Property Pre-Mortem: How a $59K Flip Lost Half
In property flipping there is an after-the-fact report, at the time of closing there can be no change. A pre-mortem moves this report to the pre-acquisition. The idea is to be pessimistic and assume the flip did badly and then come up with the exact reasons for the bad performance. It takes an hour, but there is no financial cost.
In this article you get the report early and often. While the scenario is an example, each failure point is taken from a real source: Freedom Mortgage's tips and tricks, EBSCO's research starter, and Rocket Mortgage's explanation of 70% rule. The property being purchased is $180,000, the renovation budget is $30,000, and the sale will be $300,000. Freedom Mortgage uses the same numbers, and points out they don't have much room to make a mistake.

Entry One: The Plan on Day One
Looks good as initial plan. $300,000 ARV times 70% will give $210,000. Less a $30,000 for repair budget, it equals $180,000, which is just enough for the purchase price.
The investor uses 4 months of holding costs at $2,000 a month, a 6% sales commission, and $5,000 in the cost of buying the property. All of these sample numbers lead to a projected pre-tax profit of $59,000. According to the 70% rule, this deal is a go, but nothing to back you up.
Rocket Mortgage warns that this rule ignores financing costs, market changes and property taxes. It is the kick-off to the pre-mortem.
Entry Two: Month Three, Flipping Property Costs Run Over
Foundry Financial: the very first failure point they list, the "Cost of Renovation" section, which can easily turn a good deal into a barely profitable deal. In our example, when the contractor removes the wall in the living room, there is unexpected damage.
The renovation costs are over budget by 25%, for $30,000 to $37,500, $7,500 impact. This is not an unrecoverable disaster by itself, but profit goes from $59,000 to $51,500, the investor assumes that the schedule will offset that change.
Yet, it doesn't. When something unexpectedly needs fixing, the schedule is thrown off, causing a delay in the expected due date.
Entry Three: Month Six, Flipping Property Holding Costs Keep Running
This is a summary of the recurring monthly expenses: mortgage, property taxes, utilities, homeowners insurance, while the property is on the market.
Originally, the plan expected 4 months, but it's extended to 8 months. This is applied to the holding cost for 8 months, which is 2,000 USD/month. As a result, the total profit decreases by 8,000 USD to reach 43,500 USD.
There were no big surprises in six month; the calendar kept moving on.

Entry Four: Month Eight, the Market Moves Under Flipping Homes
The research starter from EBSCO highlights the current market environment for house flipping: higher borrowing costs, higher renovation costs, and constrained housing inventory. These market conditions will squeeze margins, even for experienced investors.
In this case, the property sells 5% below target and completes for $285,000 (as opposed to $300,000). With 6% commission – it falls by $900 to $17,100. Again, not significant – but not changing the outcome either.
Freedom Mortgage recommends coming up with a "Plan B if there's not enough time or the property can't be sold for the price you want." This investor does not have a Plan B. They are forced to sell the property due to mounting holding costs.
The Flipping Property Post-Mortem: Plan Against Reality
Here are the numbers side by side.
| Line | Plan | Reality | Change |
|---|---|---|---|
| Sale price | $300,000 | $285,000 | -$15,000 |
| Purchase price | $180,000 | $180,000 | $0 |
| Renovation | $30,000 | $37,500 | +$7,500 |
| Holding costs | $8,000 | $16,000 | +$8,000 |
| Sales commission (6%) | $18,000 | $17,100 | -$900 |
| Buying costs | $5,000 | $5,000 | $0 |
| Pre-tax profit | $59,000 | $29,400 | -$29,600 |
Profit was down by 50.2%. There was no single failure. A 25% cost over-run, four-month delay, and a 5% reduction in price all looked sustainable. In combination, they wiped out half the profit.

Entry Five: The Tax Line Flipping Property Investors Skip
In addition, Freedom Mortgage note that gains from flipping are taxed as income, and you should consult with a tax professional. Every country is different with regards to taxation. In Australia, you will deal with GST and the margin scheme and income tax on the profit.
Using this example with an assumed 30% tax rate, the planned $59,000 becomes $41,300 after tax, and the real $29,400 becomes $20,580. The investor has only received half of the original plan, for full risk on their capital over 8 months.
What a Flipping Property Pre-Mortem Gives You Before You Buy
A pre-mortem exercise doesn't forecast the future. It aims to pinpoint where things could go wrong and get out in front of those decision points. This report points out 4 such triggers.
Reason for renovation overruns: Ascertain the percentage of escalation required before the financial forecast has to be reviewed. A 15% escalation would have pointed out the problem in the third month.
Calendar Trigger: Determine the number of months after which the costing becomes 'calendar-sensitive'. Make sure to recalculate the profit forecast immediately beyond this time.
Price Trigger- At what sale price below which a deal is considered a no-go? Note this should be based on existing comparable sales, not based on original ARV.
Plan B Trigger If the property remains unsold, Freedom Mortgage said real estate agents can turn to renting the property to reduce holding costs. But you'll want to run the numbers on this exit plan before buying.
Tracking the Triggers in FlipSync IQ
Triggers work only when actual numbers come in early and often. Flip Sync IQs ROI dashboard calculates forecasted and actual returns as the costs come in. Holding costs are based on time, and Flip vs BRRRR analyzes the rental exit before locking it in.
Be sure to add the pre-mortems into the tool at the time of purchase whether you are a Home Flipper in Sydney or Seattle. Every trigger will be linked to a number and flagged at the sixth month.

Flipping Homes Rewards Investors Who Write the Failure Report First
The biggest pitfall of a property flip doesn't happen all at once; it happens in three or four small setbacks. The renovation runs over the budget, the project is delayed, or the market takes a slight downturn. Individually these setbacks might be manageable, but when combined they can erode profit.
This strategy also gives investors a clearer way to prepare. A pre-mortem turns worry into numbers, triggers, and a Plan B. And it takes an hour of your time before you make an offer, but could save you $29,600 on the back end.
Before your next purchase, write the report. Try FlipSync IQ free and see how your flip performs when the plan meets reality.
Frequently Asked Questions
What is a pre-mortem for a house flip?
Planning based on the flip's doing poorly; creating a list of all reasons for the failure. A failure report is created prior to purchase, and each reason is converted into a numbered trigger, e.g., a renovation delay or exceeding a certain % over budget.
How much commission do sellers pay when flipping homes?
Freedom Mortgage notes that the average real estate commission at sale is 6%. So if you sell for $300,000 that's $18,000 and will be a line item in every flip budget.
What costs keep running while a flipped house sits unsold?
Mortgage, property taxes, utilities, and homeowners insurance are ongoing. Freedom Mortgage notes the costs can add up quickly and will chip away at the profit the longer it's unsold.
Do real estate agents and contractors have an edge in flipping homes?
Freedom Mortgage says yes. Real estate agents and contractors have an edge by knowing the values of properties and the costs to make repairs so they can cut costs and uncover inaccurate estimates faster than rookie investors.
What is a Plan B if a flip does not sell?
The most common, plan B is to rent the property. 'For holding costs, rental income can be a big help as you wait for a better sale price,' according to Freedom Mortgage.
What risks should buyers of flipped homes watch for?
EBSCO lists two major risks for a purchaser of a flipped home. It highlights overestimated appraisals leading to foreclosure and incomplete repairs covering structural damage. It recommends inspections and warranties as an owner of a flipped home.
