House Flipping Budget Template: Estimate Rehab Costs, Holding Costs, and Profit
A reliable fix-and-flip budget does more than total up paint, flooring, and labor. It connects the purchase price, room-by-room scope, financing, holding period, selling costs, and contingency so you can see whether a project still works when assumptions change. This reusable house flipping budget template shows how to build that model, compare contractor bids, and recalculate projected profit before small surprises become expensive decisions.
Overview
Start with the full project equation, not the renovation number alone:
Projected profit = resale price − acquisition costs − renovation costs − financing costs − holding costs − selling costs
The resale price should be based on a defensible after-repair value (ARV), supported by comparable properties and the finished scope you actually plan to deliver. For help with that part of the analysis, see the ARV Calculator for House Flippers and the step-by-step ARV calculation guide.
A useful budget has at least seven sections:
- Acquisition: purchase price, inspection, appraisal, legal or settlement charges, and other transaction costs.
- Preconstruction: surveys, design work, engineering, permits, plan review, utility transfers, and required deposits.
- Rehab: demolition, labor, materials, equipment, subcontractors, and cleanup.
- Contingency: a separate reserve for hidden conditions, scope changes, and estimating errors.
- Financing and holding: loan fees and interest, utilities, property taxes, insurance, maintenance, and the cost of keeping the property while work and sale activities continue.
- Selling: commissions or other listing-related expenses, concessions, staging, photography, repairs requested during negotiations, and closing costs.
- Summary: total project cost, projected proceeds, profit, and return measures.
This structure is more useful than a single rehab allowance because it shows where the deal is exposed. A project can have an acceptable construction estimate but fail because the sale takes longer, the loan costs more, or the property requires work outside the original scope.
How to estimate a fix-and-flip budget
1. Define the finished product
Before requesting bids, write a scope that describes the property after renovation. Specify the target buyer, quality level, layout, materials, appliances, fixtures, exterior work, and required systems work. Decide which items are essential for safety and function, which support resale appeal, and which are optional upgrades.
Then walk through the house in a consistent order: site and exterior, entry, living areas, kitchen, bedrooms, bathrooms, basement or attic, mechanical systems, and cleanup. Photograph existing conditions and record dimensions where they affect quantities. A room-by-room scope makes it easier to estimate house renovation costs and prevents a contractor from pricing a different project than the one you have in mind.
2. Separate quantities from unit costs
For each line item, record the quantity, unit, labor allowance, material allowance, and total. For example:
- Interior paint: estimated wall or floor area, surface preparation, coats, labor, and materials.
- Flooring: measured square footage, waste allowance, removal, subfloor repair, installation, transitions, and disposal.
- Cabinets: linear footage or cabinet count, hardware, installation, fillers, trim, and countertop coordination.
- Bathroom work: demolition, waterproofing, plumbing changes, tile, fixtures, ventilation, electrical, and finish work.
- Roof or exterior repairs: inspected areas, access requirements, materials, flashing, drainage, and cleanup.
Do not rely on a broad per-square-foot figure as the final estimate. Such figures can help with an early screening, but they hide the differences between cosmetic work, a full gut renovation, and a project involving structural or systems repairs.
3. Build a contractor-ready scope
Give every bidder the same written scope, finish schedule, plans, photos, and assumptions. Ask each contractor to identify exclusions, allowances, permit responsibilities, schedule assumptions, payment milestones, and change-order procedures. A low bid may simply omit demolition, disposal, prep, protection, final cleaning, or required trade work.
Compare bids line by line rather than comparing only the totals. Normalize differences by adding omitted work or removing duplicate allowances. Also evaluate who will obtain permits, coordinate subcontractors, protect existing areas, and document completed work. A clear house flip budget calculator is most useful when its inputs come from a defined scope rather than a rough guess.
4. Add non-construction costs before judging the deal
Enter the acquisition price and transaction costs first. Then add permits and preconstruction expenses, the detailed rehab estimate, and a contingency. After that, model financing, monthly holding costs, and selling expenses. Include the expected project duration from closing through construction, listing, contract, and closing—not merely the number of weeks workers are on site.
For a conservative comparison, create a base case and a downside case. The downside case might use a longer holding period, higher material or labor costs, a lower resale price, or a combination of these conditions. This is more informative than relying on a single profit projection or applying the 70 percent rule without checking the actual scope and market assumptions.
Inputs and assumptions for the worksheet
Use one row per cost item and include columns for category, description, quantity, unit, labor, materials, subcontractor, allowance, status, and notes. Add a status such as “quoted,” “measured,” “allowance,” or “not verified.” That label tells you which numbers deserve the most attention.
Acquisition and preconstruction inputs
Record the purchase price, inspection expenses, appraisal or valuation fees when applicable, settlement charges, legal costs, title-related expenses, survey work, design, engineering, permit fees, plan review, and utility setup. Confirm which costs are paid at closing and which are paid later so the cash-flow plan is realistic.
Rehab inputs
Organize the scope by room and trade. Typical categories include demolition, framing, drywall, insulation, windows and doors, roofing, siding, electrical, plumbing, HVAC, water control, kitchen, bathrooms, flooring, painting, lighting, trim, appliances, landscaping, driveway or walkways, pest treatment, and final cleaning. Mark unknown conditions separately instead of hiding them inside unrelated line items.
Contingency should be calculated from the risk of the project, not treated as leftover money. A house with open walls, aging systems, uncertain drainage, or incomplete records needs more protection than a mostly cosmetic renovation. The appropriate reserve depends on the property, scope, inspection findings, and local conditions, so state the assumption clearly and revisit it after destructive work begins.
Financing and holding inputs
Financing may include origination points or fees, interest, draw fees, appraisal charges, and extension costs if the project exceeds the loan term. Holding costs can include property taxes, insurance, electricity, gas, water, trash service, lawn care, snow removal, security, internet or monitoring, maintenance, and required association charges. Separate financing costs from operating holding costs so you can see whether the problem is the loan structure or the timeline.
Selling inputs
Estimate listing and transaction costs, buyer concessions, staging, photography, marketing, moving or storage, final touch-ups, and likely negotiation costs. The final selling budget should reflect the property’s condition and the way comparable homes are marketed.

Worked example: a simple flip house budget
The following is an illustrative model, not a market estimate. Replace every assumption with local quotes, lender terms, tax information, and comparable sales.
| Budget category | Illustrative amount |
|---|---|
| Purchase price | $180,000 |
| Acquisition and preconstruction | $7,000 |
| Rehab scope | $55,000 |
| Contingency | $8,000 |
| Financing costs | $14,000 |
| Holding costs | $9,000 |
| Selling costs | $18,000 |
| Total project cost | $291,000 |
| Projected resale price | $330,000 |
| Projected profit | $39,000 |
In this example, profit is not simply the projected resale price minus purchase price and rehab. Financing, holding, acquisition, contingency, and selling costs consume a substantial part of the spread. If the sale price falls by $10,000, the project takes two additional months, or the rehab expands beyond the contingency, the projected profit changes immediately.
For a more complete decision, calculate profit under several cases. You might use a base case with the planned scope and timeline, a cost-overrun case with additional repairs, and a slow-sale case with extra holding costs. Then compare the result with the cash required, the financing risk, and the time involved. The Maximum Allowable Offer Calculator can help you work backward from a target margin when the other assumptions are reasonably supported.
When to recalculate the budget
A flip budget is a living document. Recalculate it whenever a material input changes, rather than waiting for the monthly review. Important triggers include a new inspection finding, an opened wall or ceiling, a contractor change order, a revised permit requirement, a material substitution, a delayed inspection, a lender-rate or fee change, an approaching loan maturity date, a revised comparable sale, a price change in the listing strategy, or a buyer request for concessions.
Review the budget at minimum at four decision points: before making an offer, after inspections and contractor walkthroughs, after demolition and verification of concealed conditions, and before listing. At each review, replace allowances with actuals where possible and update the remaining-to-complete forecast. Do not count committed money as available contingency, and do not treat an unpaid invoice as savings.
Use a simple variance log with four fields: original estimate, approved change, actual or revised estimate, and reason. If the total cost rises, test the effect on profit, cash required, maximum offer, and resale pricing. If a renovation choice adds cost without a clear benefit to function, buyer appeal, or marketability, reconsider it before approving the change.
To put this template into practice, create the worksheet before submitting an offer, attach the detailed room-by-room scope, obtain comparable bids, verify the ARV separately, and save a dated copy after every major revision. That habit turns a one-time rehab cost estimate into a repeatable house flipping checklist—and gives you a clearer basis for deciding whether to proceed, renegotiate, reduce scope, or walk away.
