## Phase 1: The 70% Rule and Deal Analysis
### The 70% Rule
```
Maximum Purchase Price = (ARV x 70%) - Renovation Costs
ARV = After Repair Value (what the home will be worth fully renovated)
Example:
ARV: $300,000
70% of ARV: $210,000
Estimated Renovation: $50,000
Maximum Purchase Price: $210,000 - $50,000 = $160,000
```
**The 30% margin covers:**
- Buying closing costs (1-3%)
- Holding costs (mortgage, taxes, insurance, utilities during renovation)
- Selling costs (agent commissions 5-6%, seller closing costs 1-2%)
- Profit margin (target 10-15% of ARV minimum)
- Contingency buffer for unexpected costs
### ARV Calculation
**Step 1:** Find 3-5 comparable renovated properties that have sold within the last 3-6 months.
**Comparable criteria:**
- Within 0.5-1 mile of subject property
- Similar square footage (within 10%)
- Same bedroom/bathroom count (or close)
- Similar lot size
- Same general neighborhood quality
- Renovated to similar level as your planned renovation
**Step 2:** Adjust comparables for differences (see Home Seller Guide CMA adjustments).
**Step 3:** Calculate average adjusted price per square foot and apply to your property.
```

Comp 3: _________ address, sold $_______, $/sqft: $_______
Average $/sqft after adjustments: $_______

## Phase 2: Acquisition Strategies
### Finding Deals: Source Comparison
| Source | Discount Potential | Competition | Effort Required | Best For |
|--------|-------------------|-------------|-----------------|----------|
| MLS (listed properties) | 5-15% below market | High | Low | Beginning flippers |
| Wholesalers | 15-30% below market | Medium | Medium | Consistent deal flow |
| Auctions (foreclosure) | 20-40% below market | Medium-High | High | Experienced flippers |
| Direct mail/marketing | 20-40% below market | Low | Very High | Serious full-time flippers |
| Driving for dollars | 15-30% below market | Low | High | Local market knowledge |
| Probate/estate sales | 10-25% below market | Low-Medium | Medium | Patient investors |
| Bank REOs | 10-25% below market | Medium | Medium | All experience levels |
| Tax lien sales | Varies widely | Medium | High | Experienced investors |
### MLS Deal Finding Strategy
- Set alerts for keywords: "investor special," "as-is," "estate sale," "needs TLC," "handyman special"
- Filter for properties with 30+ days on market
- Look for price reductions
- Focus on the ugliest homes in the best neighborhoods
- Properties with expired listings may have motivated sellers
### Auction Buying Checklist
- [ ] Research auction type (foreclosure, tax sale, estate)
- [ ] Inspect exterior thoroughly (interior access may be limited)
- [ ] Research title (liens, judgments, back taxes)
- [ ] Set maximum bid before the auction and do not exceed it
- [ ] Understand payment terms (often cash or cashier's check within 24-48 hours)
- [ ] Factor in unknown interior condition into your budget
- [ ] Have funds verified and ready before bidding
- [ ] Understand "as-is" terms and eviction requirements
### Working with Wholesalers
- Build relationships with 3-5 active wholesalers in your market
- Verify their ARV and repair estimates independently
- Always inspect the property yourself before committing
- Negotiate -- wholesale prices have markup built in
- Close quickly and reliably to get first access to future deals
- Check assignment fee transparency

## Phase 3: Renovation Scope Assessment
### Property Walkthrough Evaluation
**Structural Assessment (Major Cost Items):**
- [ ] Foundation: Cracks, settling, water intrusion, bowing walls
- [ ] Roof: Age, missing shingles, sagging, leaks, remaining life
- [ ] Framing: Load-bearing wall identification, structural integrity
- [ ] Grading and drainage: Water flow away from foundation
**Systems Assessment:**
- [ ] Electrical: Panel amperage (100A minimum for modern), wiring type (copper vs aluminum vs knob-and-tube), outlet count
- [ ] Plumbing: Pipe material (copper, PEX, galvanized, polybutylene), water pressure, drain condition
- [ ] HVAC: Age, condition, efficiency, ductwork condition
- [ ] Water heater: Age, capacity, type
**Cosmetic Assessment:**
- [ ] Flooring: Condition under carpet, hardwood salvageable?
- [ ] Walls: Drywall condition, texture, damage
- [ ] Kitchen: Layout, cabinets (reface vs replace), countertops, appliances
- [ ] Bathrooms: Fixtures, tile, vanities, layout
- [ ] Paint: Interior and exterior condition
- [ ] Windows: Condition, seal integrity, style/age
- [ ] Doors: Interior and exterior condition

- [ ] Check references (call 3+ recent clients)
- [ ] Review portfolio of completed work
- [ ] Get detailed written bid (not just a total number)
- [ ] Verify no complaints with BBB or state consumer protection
