House Flip Profit Accounting: True Net Profit, Estimated vs Reconciled

What is true net profit on a flip?

Sale price minus the purchase price and its closing costs, the loan costs, the rehab, the holding costs and the selling costs, taken from reconciled books. It is the number after every cost that belonged to the deal.

It is sale minus every cost, not purchase minus sale. Here are 2 projects from the same sample report. On the gap between purchase and sale, Project 4 looks $20,000 better.

Summed to the cent from the sample ledger, so every column adds up exactly. Closing costs paid when buying sit with the purchase, and loan points and the lender's title and recording on their own loan costs line. All of them count in the profit.

Project 4 was held 81 days longer. Its holding costs were $17,833.24 higher. That is what time cost on this deal, and the books showed it line by line. In our experience, the flippers who know what every deal really made make better decisions on the next one.

The bank balance tells a third story. Project 4 put $512,000 into the bank and still lost $6,469.51. We explain that gap in cash flow vs profit in real estate bookkeeping.

Which flip costs get left out most often?

6: loan points and fees, interest over the hold, utilities while the property is empty, insurance, property tax for the months you owned it, and staging. Each is easy to miss. Together they decide the result.

Here are the 6 on Project 4, summed from its ledger.

The points sit on the loan costs line and staging in selling costs. The other 4 are the holding costs, $31,652.31 in all. The 3 loan figures on Project 4 fit together like this: the lender funded $316,200 at closing and agreed to release up to the $70,000 rehab budget in draws, a $386,200 loan, and the 2 points were charged on that full amount. The rehab drew $74,000, so the payoff at the sale was $390,200.

Why is a flip's estimate almost always higher than the result?

4 reasons: the hold runs longer than planned, the rehab runs over, the sale price lands under the estimate, and closing costs arrive in full. Each one moves the number in the same direction.

• The hold runs longer. Project 4 was planned at 135 days and held 216.
• The rehab runs over. Project 4 spent $74,000 against a $70,000 budget.
• The sale price lands under the estimate. On Project 4 it did not: the house sold at the $512,000 estimate.
• Closing costs arrive in full. On Project 4 they did: the $10,406 of loan points and purchase closing costs matched the estimate, because both were known from the closing statement and the loan terms.

2 of the 4 causes were enough to turn a profit into a loss.

What does the variance look like on a real deal?

Line by line, estimate against actual, with the difference shown. The cost group with the biggest gap tells you what to change on the next deal, which one summary number never does.

The estimate column is what the house flipping calculator gives for Project 4 before the purchase. The calculator estimates before you buy. This page reconciles after you sell.

The estimate used a $70,000 rehab budget, 4.5 months (135 days) of holding costs at $4,388 a month, and selling costs of 6%. The 3 cost differences add to exactly $15,597.51.

Holding costs are the biggest gap, so the length of the hold is what to plan differently next time. The rehab ran 5.7% over budget. We track that line by category while the work is going, in job cost accounting for house flips.

The return on cash moved too. The estimate was 10.6%: $9,128 on $85,952, the $55,800 down payment plus $10,406 of closing and loan costs and $19,746 of holding costs. The result was -6.6%: -$6,469.51 on $97,858.31.

How do active flips differ from sold ones in the reports?

A flip you still own has costs and no result yet. Shown together with sold deals, it makes a year look worse or better than it is, so reports keep active and sold projects apart.

In our real estate bookkeeping report example, Projects 8, 9 and 10 are still owned. They show their costs so far, and no net profit. The totals row counts the 7 sold projects only.

Project 9 is listed at $495,000. It has a result only after it sells.

When is a flip's profit final?

When the property's cost is cleared, the loan is at zero, every invoice for it is in, and the books are reconciled. Before that the number is provisional and can still move.

• The cost is cleared: the sale on Jun 24, 2026 took the property off the books.
• The loan is at zero: the $390,200 payoff covered the $316,200 loan at closing plus $74,000 of rehab draws.
• Every invoice is in: rehab payment 5 of 5, for the roof, was paid on Jun 4, 2026.
• The books are reconciled: on the sample report, -$6,469 is the final result.
