Max Bid Calculator Skill
Calculates maximum bid amount and decision recommendation using BidDeed.AI proprietary formula.
When to Use This Skill
- Stage 8 of Everest Ascent pipeline
- After ARV and repair estimates determined
- Before generating final report
- Any time evaluating auction opportunity
The BidDeed Formula
MAX_BID = (ARV × 70%) - Repairs - Holding - MIN(Profit_Buffer, 15% × ARV)
Where:
- ARV: After-Repair Value
- Repairs: Conservative repair estimate
- Holding: $10,000 (standard carrying costs)
- Profit_Buffer: LESSER of $25,000 OR 15% of ARV
Formula Breakdown
Component 1: ARV × 70%
Purpose: Conservative purchase price ceiling Reasoning: Industry standard for value investors Example: ARV $400K → Max $280K (70%)
Component 2: Repairs
Sources:
- Property age/condition assessment
- BCPAO photos inspection
- Drive-by evaluation
- Comparable properties Conservative Approach: Round up, not down Example: Estimate $15-20K → Use $20K
Component 3: Holding Costs
Fixed Amount: $10,000 Covers:
- Property taxes (6-12 months)
- Insurance
- HOA fees if applicable
- Utilities during renovation
- Carrying costs
Component 4: Profit Buffer
Formula: MIN($25,000, 15% × ARV) Examples:
- ARV $150K → 15% = $22.5K → Use $22.5K
- ARV $200K → 15% = $30K → Use $25K (capped)
- ARV $500K → 15% = $75K → Use $25K (capped)
Reasoning: Guarantees minimum profit while capping risk
Complete Examples
Example 1: Lower-Value Property
ARV: $180,000
Repairs: $15,000
Holding: $10,000
Profit Buffer: MIN($25K, 15% × $180K) = MIN($25K, $27K) = $25K
MAX_BID = ($180K × 70%) - $15K - $10K - $25K
= $126K - $15K - $10K - $25K
= $76,000
Example 2: Higher-Value Property
ARV: $450,000
Repairs: $35,000
Holding: $10,000
Profit Buffer: MIN($25K, 15% × $450K) = MIN($25K, $67.5K) = $25K
MAX_BID = ($450K × 70%) - $35K - $10K - $25K
= $315K - $35K - $10K - $25K
= $245,000
Example 3: Heavy Repairs
ARV: $300,000
Repairs: $60,000
Holding: $10,000
Profit Buffer: MIN($25K, 15% × $300K) = MIN($25K, $45K) = $25K
MAX_BID = ($300K × 70%) - $60K - $10K - $25K
= $210K - $60K - $10K - $25K
= $115,000
Bid/Judgment Ratio Analysis
After calculating max bid, compare to judgment amount:
RATIO = MAX_BID / JUDGMENT_AMOUNT
Decision Rules
BID (Ratio ≥ 0.75):
- Strong equity cushion
- Proceed with confidence
- Auto-approve for bidding
REVIEW (Ratio 0.60 - 0.74):
- Marginal opportunity
- Human review required
- Flag for Ariel's approval
SKIP (Ratio < 0.60):
- Insufficient margin
- Not worth risk
- Auto-reject
Example Ratio Calculations
Scenario 1: Strong BID
Max Bid: $245,000
Judgment: $280,000
Ratio: $245K / $280K = 0.875 (87.5%)
→ Decision: BID
→ Reasoning: 87.5% ratio = strong value
Scenario 2: Marginal REVIEW
Max Bid: $175,000
Judgment: $260,000
Ratio: $175K / $260K = 0.673 (67.3%)
→ Decision: REVIEW
→ Reasoning: Close to threshold, needs human judgment
Scenario 3: Clear SKIP
Max Bid: $130,000
Judgment: $285,000
Ratio: $130K / $285K = 0.456 (45.6%)
→ Decision: SKIP
→ Reasoning: Insufficient equity, too risky

Integration with Pipeline
# Stage 8: Max Bid Calculation
calc_result = max_bid_calculator_skill.calculate(
arv=arv_estimate,
repairs=repair_estimate,
judgment=auction_judgment
)
if calc_result['decision'] == 'BID':
# Proceed to report generation
generate_report(calc_result)
elif calc_result['decision'] == 'REVIEW':
# Flag for Ariel's review
flag_for_human_review(calc_result)
else: # SKIP
# Log and move on
log_skip(calc_result)
Decision Logging
Every calculation must be logged to Supabase:
supabase.table('auction_decisions').insert({
'property_id': case_number,
'arv': arv,
'repairs': repairs,
'max_bid': max_bid,
'judgment': judgment,
'ratio': ratio,
'decision': decision,
'timestamp': datetime.now(),
'reasoning': reasoning
})
Conservative Adjustments
When to Add Safety Margin:
- Unknown property condition → +$5K repairs
- No interior access → +$10K repairs
- Older property (>50 years) → +$15K repairs
- Complex title issues → Reduce ARV by 5%
Example with Safety Margin:
Base Repairs: $25,000
Unknown condition: +$5,000
Old property: +$10,000
Total Repairs: $40,000 (conservative)
Example Usage
"Use max-bid-calculator-skill to calculate bid for property with ARV $350K, repairs $30K, judgment $280K"
"Calculate max bid: ARV $180K, repairs $15K, judgment $150K"
Critical Reminders
- Always Use Formula: Don't deviate from calculation
- Conservative Repairs: Round up, not down
- Log Everything: Track all decisions in Supabase
- Respect Ratios: Don't override threshold decisions
- Profit Buffer Caps: Remember $25K maximum
