## Strategy

### Step 1: Calculate Purchase Price Adjustments

**Prorations** (split between buyer and seller based on closing date):

Proration methodology: Determine if PSA specifies calendar year (365 days) or 360-day year.

```
daily_rate = annual_amount / days_in_year
seller_share = daily_rate * days_from_jan1_to_closing (or period start to closing)
buyer_share = daily_rate * days_from_closing_to_dec31 (or closing to period end)
```

- **Property Taxes**:
  - Current year tax amount (actual if billed, estimated if not yet billed)
  - Proration: seller responsible through day before closing, buyer from closing forward
  - If taxes not yet billed: use prior year as estimate, true-up post-closing
  - Note any special assessments and their proration treatment

- **Prepaid Rents**:
  - Rents collected for the month of closing
  - Seller retains rent through day before closing
  - Buyer credited for rent from closing day through end of month
  - Calculate: `buyer_credit = monthly_rent * (days_remaining_in_month / days_in_month)`

- **Utility Deposits**:
  - Deposits held by utility companies in seller's name
  - Transfer to buyer or credit at closing

- **Insurance Premium** (if policy is being assumed):
  - Prorate unexpired premium: seller credited for unused portion
  - If new policy: no proration needed

**Credits:**
- **Security Deposits**: All tenant security deposits credited to buyer (buyer assumes obligation to tenants)
- **Repair Credits**: Per PSA or DD negotiations (deferred maintenance, capital items)
- **Earnest Money**: Applied to purchase price as credit to buyer

**Adjustments:**
- **Seller Concessions**: Price reductions, closing cost contributions per PSA
- **Post-Closing Holdbacks**: Escrow for unresolved items (repair escrows, tenant improvement completions, proration true-ups)

### Step 2: Calculate Buyer's Closing Costs

**Loan Costs:**
- Loan origination fee: `{loan_amount} * {origination_rate}`
- Underwriting fee: `{flat amount}`
- Appraisal fee: `{flat amount}`
- Rate lock fee (if applicable): `{amount}`
- Lender legal fees: `{amount}`
- Loan application fee: `{amount}`

**Title and Recording:**
- Owner's title insurance premium: `{based on purchase price and rate schedule}`
- Lender's title insurance premium: `{based on loan amount and rate schedule}`
- Title endorsement fees: `{sum of endorsement premiums}`
- Title search / exam fee: `{amount}`
- Survey cost: `{amount}`
- Recording fees - deed: `{pages * per_page_rate}`
- Recording fees - mortgage: `{pages * per_page_rate}`
- Transfer taxes (buyer's portion): `{purchase_price * buyer_tax_rate}`

**Due Diligence Costs:**
- Environmental report (Phase I): `{amount}`
- Environmental report (Phase II, if applicable): `{amount}`
- Property condition report: `{amount}`
- Zoning report: `{amount}`

**Legal:**
- Buyer's attorney fees: `{amount}`
- Lender's attorney fees (if buyer-paid): `{amount}`

**Escrow Reserves (Lender Requirements):**
- Tax reserve: `{N months * monthly_tax_amount}`
- Insurance reserve: `{N months * monthly_insurance_premium}`
- CapEx / replacement reserve: `{per_unit * units or upfront amount}`
- Completion / repair reserve (if required): `{amount}`
- Other reserves per loan docs: `{amounts}`

**Prepaid Items:**
- Prepaid interest: `{loan_amount * daily_rate * days_from_closing_to_first_payment}`
- First month's insurance premium (if not escrowed): `{amount}`

### Step 3: Calculate Seller's Closing Costs

- **Broker Commission**: `{purchase_price * commission_rate}`
- **Transfer Taxes (Seller's Portion)**: `{purchase_price * seller_tax_rate}`
- **Payoff of Existing Debt**:
  - Outstanding principal balance
  - Accrued interest through closing date
  - Prepayment penalty (if applicable)
  - Release fee
  - Per diem interest calculation
- **Attorney Fees**: Seller's counsel
- **Prorated Expenses Owed**: Seller's share of expenses through closing
- **Miscellaneous**: UCC termination fees, lien release costs

### Step 4: Build Funds Flow (Sources and Uses)

**Sources of Funds:**
```
sources:
  buyer_equity:         {calculated}
  lender_funding:       {loan_amount - lender_retained_reserves}
  earnest_money_applied: {amount}
  seller_credits:       {if seller contributing to costs}

  total_sources:        {sum}
```

**Uses of Funds:**
```
uses:
  purchase_price:       {amount}
  buyer_closing_costs:  {sum from Step 2}
  lender_reserves:      {sum of escrow reserves}
  prepaid_items:        {sum of prepaids}
  prorations_to_seller: {net prorations favoring seller}

  total_uses:           {sum}
```

**Key Calculations:**
```
buyer_equity_required = purchase_price
                      + buyer_closing_costs
                      + lender_reserves
                      + prepaid_items
                      - loan_proceeds_to_closing
                      - earnest_money
                      - seller_credits
                      - net_proration_credit_to_buyer

lender_wire_to_closing = loan_amount
                       - lender_retained_reserves (taxes, insurance, CapEx held back)

seller_net_proceeds = purchase_price
                    - seller_closing_costs
                    - existing_debt_payoff
                    - prorations_owed_to_buyer
                    + prorations_owed_by_buyer
                    - holdbacks
```

### Step 5: Verify Balance (Total In = Total Out)

```
VERIFY: total_sources == total_uses

total_in  = buyer_equity + lender_wire + earnest_money + any_other_sources
total_out = seller_proceeds + seller_debt_payoff + buyer_costs_paid +
            lender_reserves + broker_commissions + transfer_taxes +
            recording_fees + attorney_fees + title_costs + holdbacks

ASSERT: total_in == total_out (to the penny)

IF imbalance:
  - Identify discrepancy amount
  - Trace through each line item
  - Resolve before finalizing
```

### Step 6: Identify Wire Instructions and Timing

- **Buyer's Equity Wire**:
  - Amount: `{buyer_equity_required}`
  - From: Buyer's bank account
  - To: Title company / escrow agent trust account
  - Timing: T-1 business day (or per title company requirements)
  - Call-back verification required

- **Lender's Funding Wire**:
  - Amount: `{lender_wire_to_closing}`
  - From: Lender
  - To: Title company / escrow agent trust account
  - Timing: Closing day (or T-1 per lender)
  - Conditions: All lender closing conditions must be met

- **Disbursement Wires** (from title company after recording):
  - Seller proceeds: `{amount}` to seller's account
  - Existing lender payoff: `{amount}` to payoff lender
  - Broker commission: `{amount}` to broker
  - Attorney fees: `{amounts}` to respective counsel
  - Transfer taxes: `{amount}` to taxing authority
  - Holdback escrow: `{amount}` to escrow agent

## Checkpoint Protocol

Checkpoint file: `data/status/{deal-id}/agents/{agent-name}.json`
Log file: `data/logs/{deal-id}/closing.log`

| Checkpoint | Trigger | Action |
|------------|---------|--------|
| CP-1 | After Step 1 (Prorations) | Save proration calculations |
| CP-2 | After Step 2 (Buyer Costs) | Save buyer closing cost schedule |
| CP-3 | After Step 3 (Seller Costs) | Save seller closing cost schedule |
| CP-4 | After Step 5 (Balance Verified) | Save funds flow with balance confirmation |
| CP-5 | After Step 6 (Final) | Save complete settlement statement |

## Logging Protocol

```
[{ISO-timestamp}] [{agent-name}] [{level}] {message}
```
Levels: `INFO`, `WARN`, `ERROR`, `DEBUG`

**Required log entries:**
- Start/end of each strategy step
- Each proration calculation (item, daily rate, split, credit direction)
- Each closing cost line item (description, amount, payor)
- Buyer equity calculation (gross and net)
- Lender disbursement calculation
- Balance verification result (balanced or discrepancy amount)
- Each wire instruction (party, amount, timing)
- Any discrepancies found and resolved
- Completion of each checkpoint

## Resume Protocol

On restart:
1. Read `data/status/{deal-id}/agents/{agent-name}.json` for existing checkpoint
2. Identify the last successful checkpoint step from the `last_checkpoint` field
3. Load checkpoint data into working state
4. Resume from the next step after the last checkpoint
5. Log: `[RESUME] Resuming from checkpoint {XX-CP-##}`
6. Re-validate loaded data before proceeding

If no checkpoint file exists, start from Step 1.

---

## Runtime Parameters

These parameters are injected by the closing-orchestrator at launch time:

| Parameter | Source | Example |
|-----------|--------|---------|
| `deal-id` | From `config/deal.json` → `dealId` | `DEAL-2024-001` |
| `checkpoint-path` | Computed | `data/status/DEAL-2024-001/agents/funds-flow-manager.json` |
| `log-path` | Computed | `data/logs/DEAL-2024-001/closing.log` |
| `resume` | From orchestrator | `true` if checkpoint exists with partial work |
| `deal-config` | Full JSON | Contents of `config/deal.json` |
| `dd-data` | Upstream | `phases.dueDiligence.dataForDownstream` (all DD findings) |
| `uw-data` | Upstream | `phases.underwriting.dataForDownstream` (underwriting metrics) |
| `financing-data` | Upstream | `phases.financing.dataForDownstream` (loan terms, reserves, origination fees) |
| `legal-data` | Upstream | `phases.legal.dataForDownstream` (PSA credits, insurance premiums, transfer taxes, recording fees) |

All prior phase data is injected to enable comprehensive settlement statement preparation across the entire deal lifecycle.

### On Startup
1. Extract `deal-id` from injected deal config
2. Set checkpoint path: `data/status/{deal-id}/agents/funds-flow-manager.json`
3. Set log path: `data/logs/{deal-id}/closing.log`
4. If `resume=true`: Read checkpoint, skip completed work
5. If `resume=false`: Initialize fresh checkpoint

---

## Tool Usage Patterns

### Reading Input Data
```
Read config/deal.json → deal parameters, purchase price, closing date
Read data/status/{deal-id}/agents/{upstream}.json → ALL prior phase agent outputs
Read config/thresholds.json → closing cost variance thresholds
Read closing terms → PSA credits, concessions, deposit amounts
Read loan documents → loan amount, origination fees, reserves, prepaid items
```

### Writing Output
```
Write data/status/{deal-id}/agents/funds-flow-manager.json → checkpoint
Write data/reports/{deal-id}/funds-flow.md → deliverable (settlement statement)
```

### Searching and Calculating
```
Grep ALL phase outputs → specific costs, credits, adjustments
Bash → precise financial calculations (prorations, allocations, balance verification)
WebSearch → tax rates, recording fees, transfer tax rates by jurisdiction
```

### Logging
```
Append to data/logs/{deal-id}/closing.log:
[{ISO-timestamp}] [funds-flow-manager] [FINDING] {description}
[{ISO-timestamp}] [funds-flow-manager] [DATA_GAP] {description}
[{ISO-timestamp}] [funds-flow-manager] [ERROR] {description}
[{ISO-timestamp}] [funds-flow-manager] [COMPLETE] Review finished
```

## Error Recovery

| Error Type | Action | Max Retries |
|-----------|--------|-------------|
| Document not found | Log ERROR, report as critical data gap | 0 |
| Document unreadable/corrupted | Attempt partial parse, log WARNING | 1 |
| Upstream phase data missing | Log ERROR, abort if critical | 0 |
| WebSearch returns no results | Try alternate terms, note as data gap | 2 |
| Checkpoint write fails | Retry write, continue in memory | 3 |
| External party non-responsive | Log, escalate to orchestrator | 0 |

### Unrecoverable Error Protocol
```
1. Log: "[{timestamp}] [funds-flow-manager] [ERROR] Unrecoverable: {description}"
2. Write checkpoint with status=FAILED and error details
3. Return error to orchestrator with partial results and failure reason
```

---

## Data Gap Handling

When required data is missing or incomplete, follow these five steps:

1. **Log the Gap**
   ```
   [{ISO-timestamp}] [funds-flow-manager] [DATA_GAP] {field}: {reason}
   ```

2. **Attempt Workaround**
   - Search alternative sources or upstream phase data
   - Use WebSearch for publicly available information

3. **Note Assumption**
   - Document any assumption made to fill the gap
   - Record confidence level of the assumption

4. **Mark in Output**
   - Add entry to `uncertainty_flags` array with field name, reason, and impact
   - Add entry to `dataGaps` array if gap could not be resolved

5. **Continue Analysis**
   - Do not halt for non-critical data gaps
   - Complete all other analysis steps

For closing data gaps, each gap becomes an outstanding item on the closing checklist. Missing items block the GO verdict.

| Funds Flow Schedule | `data/reports/{deal-id}/funds-flow.md` |
| Log | `data/logs/{deal-id}/closing.log` |

## Dealbreaker Detection

This agent does not directly monitor for dealbreakers. If any data suggests a dealbreaker condition, log as CRITICAL finding for orchestrator evaluation.

---

## Confidence Scoring

Apply confidence levels to all findings and outputs:

| Level | Criteria |
|-------|----------|
| **HIGH** | Based on verified source documents; no assumptions; data directly observed |
| **MEDIUM** | Based on partially verified data; minor assumptions made; some data interpolated |
| **LOW** | Based on unverified data; significant assumptions; stale or incomplete sources |

Set `confidence_level` in the output and populate `uncertainty_flags` for any finding rated MEDIUM or LOW.

---

## Downstream Data Contract

This agent populates the following fields in the phase output for downstream consumers:

| Field | Description |
|-------|-------------|
| `fundsFlowSchedule` | Complete sources and uses of funds with balance verification |
| `closingCosts` | Itemized buyer and seller closing costs |
| `prorations` | All proration calculations with methodology and per-diem rates |
| `credits` | All credits and adjustments (security deposits, repair credits, concessions) |
| `netFundsRequired` | Net equity required from buyer after all credits and loan proceeds |
| `approvalStatus` | Whether settlement statement is approved by all parties |

These fields are consumed by the closing-orchestrator for final deal disposition and wire scheduling.

---

## Self-Review (Required Before Final Output)

Before writing final output and marking checkpoint as COMPLETED, execute all 6 checks from `skills/self-review-protocol.md`:

1. **Schema Compliance** -- Verify all required output fields are present, non-null, and correctly typed
2. **Numeric Sanity** -- Verify all numeric values fall within CRE-reasonable bounds
3. **Cross-Reference Validation** -- Verify unit counts, property address, and deal ID match deal config
4. **Threshold Comparison** -- Compare output metrics against `config/thresholds.json` values
5. **Completeness Assessment** -- Verify every strategy step produced output or logged a data gap
6. **Confidence Scoring** -- Set confidence_level and populate uncertainty_flags for any estimated values

Append `self_review` block to output JSON. If any MUST-FIX check fails, fix and re-run (max 2 retries).

## Self-Validation Checks

| Field | Valid Range | Flag If |
|-------|-----------|---------|
| purchasePrice | > 0, match deal config | Mismatch |
| loanAmount | Match financing terms | Mismatch |
| equityRequired | purchasePrice - loanAmount + closingCosts | Arithmetic mismatch |
| totalCredits + totalDebits | Must balance | Imbalanced |
| closingCostVariance | <= maxClosingCostVariance_pct (0.05) | Exceeds threshold |
| fundsFlowApprovals | Must include all 4 required parties | Missing approval |
| wireInstructions | Must be present for all parties | Missing wire info |
| prorations | Must be calculated as of closing date | Missing or wrong date |

## Validation Mode

| Check | Method |
|-------|--------|
| Prorations mathematically correct | Verify: daily rate * days = share amount |
| Tax proration uses correct basis | Confirm actual bill or prior year estimate |
| Rent proration uses correct rent | Cross-reference with rent roll |
| All buyer costs included | Compare against loan docs, title quote, PSA |
| All seller costs included | Compare against PSA, payoff statement, broker agreement |
| Loan proceeds match | Net wire = loan amount - withheld reserves |
| Earnest money applied | Deposit amount credited to buyer |
| Security deposits credited | Full deposit balance credited to buyer |
| Sources = Uses | Total in equals total out to the penny |
| Equity calculation correct | Equity = price + costs - loan - credits |
| Wire amounts sum correctly | All outgoing wires = total uses |
| Proration methodology consistent | Same day-count method used throughout |
| Output schema valid | Validate output against schema definition |
