Flip a House flip house budget worksheet Basics
A flip house budget worksheet is a planning and tracking tool for a single property. It should show what you expect to spend, what you actually spend, and how the changes affect projected profit. Keep each property separate so purchase costs, rehab payments, holding expenses, and sale costs do not blend together.
The worksheet should support two decisions: whether the deal works before an offer, and whether the project remains on budget after work begins. A simple spreadsheet is often enough when the categories are clear and the entries are updated consistently.
Deal Analysis
Estimate purchase price, renovation costs, financing, resale value, selling expenses, and target profit before making an offer.
Project Control
Compare the approved budget with invoices, checks, card charges, and completed work throughout the renovation.
Final Reporting
Summarize total investment, sale proceeds, closing costs, and realized profit for your records and tax professional.
| Worksheet Area | Main Purpose | Typical Entries |
|---|---|---|
| Acquisition | Measure the purchase commitment | Price, inspection, title, lender fees |
| Rehab | Control the renovation budget | Labor, materials, permits, contingency |
| Holding | Track time-related costs | Interest, insurance, utilities, taxes |
| Disposition | Estimate the sale expense | Agent fees, repairs, concessions, closing costs |
| Summary | Review the deal result | Total cost, sale price, profit, margin |
Create one file or tab for one address. Combining several projects in one undifferentiated list makes it harder to identify overruns and reconcile payments.
Build the Worksheet Step by Step
Use a structure that is easy to update from a phone, shared drive, or desktop spreadsheet. The goal is not a complicated model; the goal is a reliable record that another person can understand.
Create the Property Header
Add the property address or project name, acquisition date, planned completion date, expected listing date, and the person responsible for updates. Use a unique project label if multiple properties are active.
Add Budget Categories
Separate acquisition, rehab, holding, financing, selling, and administrative costs. Add a contingency line rather than hiding extra money inside another category.
Record Each Transaction
Enter the date, vendor, description, amount, payment method, invoice or receipt reference, and whether the amount is paid. One line per transaction keeps the audit trail readable.
Compare Budget to Actual
Add budget, committed, paid, and remaining columns. Review differences by category and investigate any material variance before approving more work.
| Date | Vendor | Category | Description | Amount | Status |
|---|---|---|---|---|---|
| 2026-09-04 | General contractor | Rehab | Contract deposit | $10,000 | Paid |
| 2026-09-05 | Materials supplier | Rehab | Tile purchase | $300 | Paid |
| 2026-09-12 | Lender | Financing | Interest payment | $1,250 | Paid |
| 2026-09-18 | Utility provider | Holding | Monthly service | $180 | Scheduled |
Keep the transaction log factual. “Kitchen work” is less useful than “cabinet installation, phase one.” Clear descriptions help you identify duplicate payments, missing receipts, and costs that belong in another project.
A signed contractor agreement or approved purchase order may not be paid yet, but it still affects the project forecast. Track committed costs separately from paid costs.
Calculate the Maximum Offer and Profit
Before making an offer, use conservative assumptions. The worksheet should show the relationship between expected resale value and every cost required to reach that sale. A higher resale estimate does not automatically justify a higher purchase price.
A practical maximum-offer calculation is:
Estimated resale value − purchase costs − rehab budget − holding costs − selling costs − desired profit = maximum allowable offer
The formula is only as useful as the assumptions behind it. Review recent comparable sales, verify the scope of work, estimate the project timeline, and include financing charges that could change if construction takes longer.
| Calculation Item | Example Planning Method | Review Question |
|---|---|---|
| Estimated resale value | Use supportable comparable sales | Is the finished condition realistic for the neighborhood? |
| Purchase costs | Add price and acquisition fees | Are inspection, title, recording, and lender charges included? |
| Rehab budget | Price labor and materials by scope | Are permits, disposal, and specialty trades included? |
| Contingency | Reserve a percentage of rehab | What happens if hidden damage is discovered? |
| Holding costs | Estimate time-based expenses | Does the budget survive a delayed sale or permit? |
| Selling costs | Include commissions and closing items | Are concessions, repairs, and staging considered? |
| Desired profit | Set the minimum acceptable result | Does the return justify the project risk? |
Base Case
Uses the expected purchase price, scope, timeline, and resale value. This is the main decision scenario.
Conservative Case
Uses a lower resale value, higher rehab cost, and longer hold period to test downside exposure.
Upside Case
Shows what improved pricing or a faster project could produce, but should not be required for the deal to work.
The upside scenario is useful for context, but the purchase decision should be supported by assumptions you can reasonably defend.
Track Actual Costs and Prevent Budget Drift
The strongest worksheet is updated during the project, not rebuilt after the renovation. Set a recurring review time in 2026 and process every receipt, invoice, check, and card charge during that review.
Use separate columns for budget, committed, paid, and variance. A category can appear under budget in paid costs while already exceeding the plan through approved commitments. Reviewing both views gives a more accurate forecast.
| Control | What to Check | Recommended Frequency |
|---|---|---|
| Receipt matching | Every transaction has supporting documentation | Weekly |
| Payment review | Amount, vendor, project, and method are correct | Weekly |
| Category variance | Actual and committed costs versus budget | Weekly |
| Contractor progress | Payments match completed work | At each draw |
| Forecast update | Remaining work and revised completion date | Every two weeks |
| Bookkeeping reconciliation | Worksheet agrees with bank or card records | Weekly or biweekly |
Weekly Budget Review:
- Enter every new payment, invoice, and receipt
- Match transactions to the correct property and category
- Update committed costs and remaining budget
- Review rehab variances and pending change orders
- Reconcile the worksheet with bank and card records
Avoid giving broad spreadsheet access to people who do not need financial account information. A shared project worksheet can let the team record job costs while limiting access to the main accounting system. Establish who enters transactions, who verifies them, and who approves changes to the budget.
Repeated material purchases, delivery fees, permit charges, and card transactions can materially change a project total. Small entries still deserve a category and a receipt reference.
FAQ and Final Review
A worksheet cannot replace due diligence, contractor oversight, lender terms, or professional accounting advice. It can make assumptions visible and give you a consistent method for reviewing the project before more money is committed.
| Final Review Area | Green Light Question |
|---|---|
| Scope | Is the renovation list specific enough to price? |
| Timeline | Does the holding budget cover delays? |
| Funding | Are interest, points, and draw costs included? |
| Exit | Is the resale estimate supported by the finished scope? |
| Reporting | Can every major cost be traced to documentation? |
Q: What should a flip house budget worksheet include?
Include property details, purchase costs, rehab categories, contingency, financing, holding expenses, selling costs, projected resale value, desired profit, and a transaction log for actual payments.
Q: Should I use one worksheet for multiple properties?
Use a separate worksheet or clearly separated project tab for each property. This keeps costs, receipts, contractor payments, and profit calculations tied to the correct deal.
Q: How often should I update the worksheet?
Update it at least weekly. Enter transactions while receipts and invoices are available, then compare budget, committed, and paid amounts before approving additional work.
Q: What is the most important number before making an offer?
The maximum allowable offer is a key decision number, but it depends on realistic resale value, complete project costs, financing, holding time, selling expenses, contingency, and desired profit.
A useful worksheet is simple enough to maintain, detailed enough to audit, and current enough to guide the next project decision. Review the numbers before signing contracts, funding change orders, or listing the property.
