Fix & Flip Budget Mistakes That Delay Funding (and How to Avoid Them)

We’re based in Des Moines, WA and work across Seattle & select states. If your budget is bulletproof, underwriting moves faster—every time.

The 7 Budget Mistakes We See Most

  1. No scope detail: A single line “Kitchen – $25k” isn’t enough. Break out cabinets, counters, appliances, electrical, plumbing, finishes, labor.
  2. Optimistic timelines: Trades, permits, inspections, and lead times rarely align perfectly. Padding realistic durations prevents draw friction.
  3. Missing contingency: Old homes surprise you. A 10–15% contingency is common; complex rehabs may need more.
  4. Ignoring holding costs: Taxes, insurance, utilities, interest. Buyers often underestimate total carry during rehab + marketing.
  5. Weak comps: ARV comps older than 3–6 months or outside the micro-neighborhood raise flags. Align bed/bath, style, and improvements.
  6. No permit plan: If structural, electrical, or plumbing is touched, outline permit status. Silent plans slow underwriting.
  7. Unclear draws: Lenders fund completed work. Stage milestones so inspections are efficient and cash flow stays smooth.

What a “Fundable” Rehab Budget Looks Like

Seattle-Area Example: 1940s SFR

Scope highlights: roof replacement, panel upgrade, partial re-pipe, kitchen + 2 baths, windows, refinished floors, interior/exterior paint, landscaping.

Draws (sample):

  1. Demo & Rough-In — 20% (demo, framing fixes, MEP rough-ins)
  2. Exterior Systems — 20% (roof, windows, panel)
  3. Interior Close-In — 20% (insulation, drywall, prime)
  4. Kitchens & Baths — 25% (cabs, counters, tile, fixtures)
  5. Finishes & Final — 15% (floor refinish, paint, landscaping, punch)
