For bookkeeping purposes, a house flip is not a rental asset - it is a project. Record the purchase and every capitalizable project cost in a work-in-progress (WIP) asset account for that specific property, keep operating overhead on the P&L, and track hard-money draws as loan balance increases. When the property sells, the WIP balance moves to cost of goods sold and the project's true profit appears on one clean report. Both closing statements - purchase and sale - must be reconciled line by line.
House flipping bookkeeping works differently from rental bookkeeping in one fundamental way: for bookkeeping purposes, a flip is a project, not a rental asset. You do not set the house up as a fixed asset and depreciate it. Instead, the purchase price, acquisition closing costs, rehab, and carrying costs accumulate in a work-in-progress (WIP) asset account for that specific property — the same way a builder tracks a job. Your profit and loss statement stays quiet while you own the house. When it sells, the entire WIP balance transfers to cost of goods sold, and the project's real profit appears in a single, clean report. This guide walks through the full system: the account structure, job costing per property, hard-money draws, and reconciling both closing statements.
A rental property goes on the books as a fixed asset because you hold it to produce income over years. A flip exists to be sold. That difference drives the entire bookkeeping design.
On the tax side, the IRS is explicit that inventory — property held primarily for sale to customers in the ordinary course of business — cannot be depreciated (IRS Publication 946). And under 26 U.S.C. § 1221(a)(1), property held primarily for sale to customers is excluded from the definition of a capital asset, which is the statutory root of what practitioners call dealer treatment. Whether any particular investor is a dealer, and whether a given flip produces ordinary income subject to self-employment tax (IRS Topic No. 554) or something else, depends on facts your CPA weighs — frequency of sales, intent, holding period, extent of improvements, and more. Do not assume either answer.
Here is the good news: the bookkeeping is the same either way. If you accumulate every project cost in a per-property WIP account with documentation behind each line, your CPA can apply whatever treatment the facts support. If you dump everything into an expenses pile, nobody can reconstruct the project's cost — and that is where returns get amended.
You need three layers, and they map cleanly onto QuickBooks Online:
If you also own rentals, do not blend the two systems in one undifferentiated account list. Flip WIP accounts and rental fixed-asset accounts should be visibly separate, and ideally the activities live in separate entities with separate books — a structure covered in our guide to bookkeeping for multiple LLCs.
The single most common flip bookkeeping error is mixing project costs with operating overhead. Project costs attach to a specific house and wait in WIP until the sale. Overhead keeps the business running regardless of any one house and belongs on the P&L now. Use this worksheet to route every transaction:
| Cost category | Typical transactions | Where it posts | Documentation needed |
|---|---|---|---|
| Purchase price | Contract price of the property | WIP asset – Acquisition | Executed settlement statement (ALTA statement or Closing Disclosure), purchase contract |
| Acquisition closing costs | Owner's title insurance, settlement/escrow fees, legal fees, recording fees, transfer taxes, surveys | WIP asset – Acquisition | Settlement statement, line by line |
| Financing costs | Points/origination fees, lender's title policy, lender-required appraisal, draw inspection fees, doc fees | WIP asset – Financing costs (separate sub-account — tax treatment differs from acquisition costs) | Loan agreement, lender fee schedule, settlement statement |
| Rehab hard costs | Contractor payments, materials, installed appliances, permits, dumpsters, engineering/design fees | WIP asset – Rehab | Contractor agreement, itemized invoices, lien waivers, permit receipts, W-9s for 1099 reporting |
| Holding costs | Hard-money/private loan interest, property taxes, builder's-risk insurance, utilities, lawn care, security | WIP asset – Holding costs (flag interest and taxes for your CPA — capitalization rules under section 263A may apply) | Monthly loan statements, tax bills, insurance declarations, utility bills |
| Selling costs | Agent commissions, seller-paid closing costs, buyer concessions, staging, listing photos | Expense at sale (selling costs, in the cost-of-sales section of the P&L) — not WIP | Listing agreement, sale settlement statement, staging invoices |
| Operating overhead | Software, bookkeeping, office, phone, general marketing, education, vehicle costs not tied to one job | Expense when incurred (overhead on the P&L) | Receipts, mileage log |
| Owner sweat equity | Your own unpaid labor on the project | Not posted — there is no third-party transaction to record | N/A (track hours separately for management purposes if useful) |
Why the separate Financing costs bucket? IRS Publication 551 (rev. Dec. 2025) lists settlement costs that are added to the basis of purchased real property — title insurance, legal and recording fees, transfer taxes — but specifically excludes amounts connected to getting a loan: points, origination fees, mortgage insurance premiums, credit report costs, and lender-required appraisal fees. Keeping loan costs in their own sub-account means your tax preparer can apply the correct treatment without unpicking a blended number. That is the recurring theme of good flip bookkeeping: record categories the CPA can act on; do not bake tax conclusions into the ledger.
Most flip bookkeeping guides stop at costs. But the loan side is where books most often break, because hard-money loans behave differently from a mortgage:
One flag for your tax preparer: uniform capitalization rules under section 263A can require producers of real property to capitalize certain indirect costs, including interest — though a small-business-taxpayer exemption tied to the section 448(c) gross receipts test excludes many flippers. Whether your interest and property taxes are capitalized or deducted for tax purposes is a facts-and-circumstances call for your CPA. Your job in the books is simpler: keep interest and taxes cleanly identified by project so either answer takes minutes, not hours.
The settlement statement (an ALTA statement or Closing Disclosure) is the most information-dense document in a flip, and it must be entered line by line — never as one lump. A single wire out of your bank account at purchase actually contains the purchase price, several categories of closing costs, loan fees, prorations, and credits. The bank feed shows one number; the books need the whole story.
Reconciliation means the entry balances to the actual cash that moved: every debit and credit on the statement is posted somewhere deliberate, and the net equals your wire. Do this twice per flip — once at purchase, once at sale. The sale-side statement adds the loan payoff, accrued interest, commissions, and prorations, and the net proceeds wire is what remains. If your entry does not tie to the wire to the dollar, something is misposted.
Buying and selling through several projects a year and behind on entering the statements? That is a defined, fixable backlog — see how QueueFortress handles monthly real estate bookkeeping for flippers, including per-project job costing and closing-statement entry.
All numbers below are illustrative — a composite for teaching, not a client's actual deal. Meet the 412 Maple Street flip.
Contract price $210,000. Hard-money lender commits $207,000 total: $147,000 funded at closing plus a $60,000 rehab holdback. The settlement statement shows:
| Settlement statement line | Amount | Posts to |
|---|---|---|
| Purchase price | $210,000 | WIP – Maple St – Acquisition |
| Owner's title insurance | $1,150 | WIP – Maple St – Acquisition |
| Settlement and legal fees | $650 | WIP – Maple St – Acquisition |
| Recording and transfer taxes | $900 | WIP – Maple St – Acquisition |
| Loan points (2% of $207,000) | $4,140 | WIP – Maple St – Financing costs |
| Lender-required appraisal | $600 | WIP – Maple St – Financing costs |
| Lender's title policy | $850 | WIP – Maple St – Financing costs |
| Seller credit for accrued property taxes | ($850) | WIP – Maple St – Holding costs (credit) |
| Loan funded at closing | ($147,000) | Hard-money loan payable |
| Cash to close (your wire) | $70,440 | Business checking |
The entry balances: $218,290 of project costs, funded by a $147,000 loan, an $850 tax proration credit, and your $70,440 wire. The books now show a $217,440 net WIP asset and a $147,000 liability — and $0 of expense on the P&L.
Over four months the rehab costs $62,300 — contractor payments, materials, and permits, each tagged to the Maple St project and posted to WIP – Rehab as paid. The lender reimburses $60,000 across three draws; each reimbursement is a deposit that increases the loan payable to its final $207,000 balance. The extra $2,300 of rehab came out of pocket. Meanwhile, holding costs accumulate in WIP – Holding: $8,400 of hard-money interest, $1,750 of property taxes paid (offset by the $850 seller credit already recorded), $1,400 of builder's-risk insurance, and $900 of utilities.
The house sells for $339,900. The sale-side settlement statement shows a $18,695 agent commission, $2,900 of seller closing costs, a $3,000 buyer concession, a $600 property-tax proration owed to the buyer, and the lender payoff of $207,000 principal plus $1,050 of final accrued interest. Net proceeds wired to you: $106,655. The selling costs ($25,195 total) post as selling expenses; the payoff clears the loan; the final interest joins WIP – Holding.
Last entry: transfer the finished project's WIP balance to cost of goods sold.
| Project P&L — 412 Maple St (illustrative) | Amount |
|---|---|
| Sale price | $339,900 |
| Cost of goods sold — Acquisition (price + closing costs) | ($212,700) |
| Cost of goods sold — Financing costs | ($5,590) |
| Cost of goods sold — Rehab | ($62,300) |
| Cost of goods sold — Holding costs (net of seller credit) | ($12,650) |
| Selling costs | ($25,195) |
| Project gross profit | $21,465 |
Here is the proof the books are right: cash invested was $70,440 at closing, $2,300 of unreimbursed rehab, and $12,450 of holding costs paid along the way — $85,190 total. Cash returned was $106,655. The difference is $21,465, exactly the profit the project P&L reports. When flip books are kept properly, profit and cash reconcile to the dollar. When they do not, a draw was booked as income, a settlement statement was lumped, or a project cost leaked into overhead.

For a flipping business, Projects (available in QBO Plus and Advanced) is usually the better fit: it groups every transaction, including WIP postings, under one project and produces per-flip profitability reports. Classes work but require more discipline to keep balance-sheet activity tagged. Some investors use both — Projects per property, classes per entity or market.
Two entries. Pay the contractor: debit WIP – Rehab for the project, credit checking. Receive the lender's reimbursement: debit checking, credit the hard-money loan payable. The draw is never income, and the loan balance should match the lender's statement after every draw.
Because it should not. Project costs accumulate on the balance sheet in WIP and hit the P&L as cost of goods sold only when the property sells. During the project, monitor the WIP balance and the project's budget-vs-actual report instead of the P&L.
That is a facts-and-circumstances determination your tax professional makes. Property held primarily for sale to customers is excluded from capital-asset treatment under 26 U.S.C. § 1221(a)(1), and profits from a flipping trade or business can be subject to self-employment tax — but frequency of sales, intent, and holding period all matter. Keep complete per-project cost records so your CPA can support whichever position the facts justify.
The property's role changes, so its bookkeeping changes: the accumulated project cost moves from WIP into fixed-asset accounts, and depreciation setup becomes a tax conversation for your CPA. That path looks a lot like BRRRR — our BRRRR bookkeeping workflow walks through it.
