# Fix and Flip Budgeting: How to Build a Scope of Work That Protects Your Profit
The #1 killer of fix and flip deals isn't market timing, financing, or deal flow β it's inaccurate budgeting. Here's how to build a scope of work that actually holds up.
What Is a Scope of Work?
A scope of work (SOW) is a detailed document outlining every renovation task, material specification, and associated cost for your flip project. It serves multiple purposes:
- Communicates your vision to contractors
- Gets apples-to-apples bids from multiple contractors
- Forms the basis of your draw schedule with your lender
- Protects your profit margin by forcing upfront clarity

Always Add a Contingency
No matter how carefully you plan, something unexpected will happen. Standard contingency: - New investors: 20β25% - Experienced investors: 10β15%
Getting Contractor Bids
- Always get at least 3 bids per trade
- Require itemized bids β not lump sums
- Check references and license/insurance before signing anything
- Use lien waivers with every payment
How Lenders Use Your SOW
Your hard money lender will review your SOW to: 1. Approve the total rehab budget for draw funding 2. Validate your ARV against the planned improvements 3. Identify red flags (unrealistically low estimates)
A well-prepared SOW speeds up loan approval. An incomplete or unrealistic one can delay or kill a deal.
