max-bid-calculator-skill
Calculate maximum bid using BidDeed formula and bid/judgment ratios to determine BID/REVIEW/SKIP decisions
When & Why to Use This Skill
The Max Bid Calculator Skill is a specialized financial tool designed for real estate investors and auction participants to determine the optimal purchase price for properties. By utilizing the proprietary BidDeed formula, the skill accurately factors in After-Repair Value (ARV), repair estimates, holding costs, and profit buffers. It streamlines the decision-making process by providing automated 'BID', 'REVIEW', or 'SKIP' recommendations based on equity ratios, ensuring that every investment aligns with conservative risk management standards and profitability targets.
Use Cases
- Real Estate Auction Evaluation: Automatically calculate the maximum safe bid for foreclosure or tax deed auctions to ensure a 70% ARV safety margin.
- Investment Risk Assessment: Analyze the ratio between calculated max bids and judgment amounts to identify high-equity opportunities versus risky marginal deals.
- Fix-and-Flip Profitability Analysis: Use the built-in profit buffer and holding cost logic to guarantee minimum returns on residential redevelopment projects.
- Workflow Automation: Integrate into real estate acquisition pipelines (like Everest Ascent) to automate the transition from property inspection to final bidding reports.
- Conservative Financial Modeling: Apply safety margins for older properties or sight-unseen purchases by adjusting repair estimates and ARV caps dynamically.

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
