    # 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

    Category-by-Category Cost Guide

    Roof - Shingle replacement (1,500 sq ft house): $6,000–$12,000 - Add $1,500–$3,000 for decking replacement if needed

    HVAC - New gas furnace + AC (2-ton): $5,000–$8,000 installed - Add $1,500–$3,000 for ductwork repair/replacement

    Electrical - Panel upgrade to 200A: $2,500–$4,500 - Whole-house rewire: $8,000–$18,000 - Outlet/switch updates only: $1,500–$3,000

    Plumbing - Full replumb (copper or PEX): $6,000–$15,000 - Repair/replace fixtures only: $1,500–$4,000 - Sewer scope + lining if needed: $3,000–$8,000

    Bathrooms - Full gut and reno (per bath): $6,000–$15,000 - Cosmetic update (tile, vanity, fixtures): $2,500–$5,000

    Flooring - LVP throughout (1,200 sf): $4,800–$7,200 installed - Carpet in bedrooms (600 sf): $1,500–$2,500

    Paint (Interior + Exterior) - Interior (1,500 sf house): $2,500–$4,500 - Exterior: $2,500–$5,000

    Windows - Double-hung replacement (per window): $350–$650 installed

    Always Add a Contingency

    No matter how carefully you plan, something unexpected will happen. Standard contingency: - New investors: 20–25% - Experienced investors: 10–15%

    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.
