  # Real Estate Rental Generation Instructions

## Mission
Implement `tenant_modules.real_estate_rental` as a full rental-management module for property managers and PM operators.

## Build order
1. Implement owner, asset, and lease master models.
2. Implement recurring charge, payment, delinquency, and remittance models.
3. Implement maintenance and inspection models.
4. Add admin resources and tests for billing, occupancy, and reporting workflows.

## Hard rules
- Use `"tenant_accounts.Organization"` and `settings.AUTH_USER_MODEL`.
- Prefix tables with `real_estate_rental_`.
- Keep monthly financial outputs reproducible from base transaction records.
- Treat move-out and deposit settlement as explicit workflows, not note fields.
- Keep translation strings module-local and audit delegated.

## Domain priorities
- Lease and resident lifecycle.
- Recurring billing and collection.
- Owner remittance and reporting.
- Maintenance approval and execution flow.

## Definition of done
- Operators can onboard assets, manage residents, bill monthly rent, track delinquency, handle maintenance, and remit to owners.
- Billing, allocation, and remittance logic are covered by tests.
  

  # Real Estate Rental System Specification

## Goal
Generate a Django tenant module for rental-property management. The system must handle owners, buildings, units, lease contracts, residents, recurring charges, payments, delinquencies, maintenance, remittance, and owner reporting.

## Django target
- Package: `tenant_modules.real_estate_rental`
- App label: `industry_real_estate_rental`
- Table prefix: `real_estate_rental_`
- Primary users: property managers, leasing staff, accounting staff, owner-reporting staff
- Primary workflow: property onboarding -> tenant contract -> monthly billing and collection -> maintenance and reporting -> owner remittance

## Functional scope
- Owner and owner-bank-account management plus management contracts.
- Building, unit, parking, and equipment masters with vacancy and facility state.
- Tenant, co-resident, and lease-contract management with renewal and move-out tracking.
- Monthly charge generation, payment capture, payment allocation, delinquency monitoring, and dunning history.
- Owner remittance, remittance details, and monthly owner reporting.
- Maintenance vendor, request, estimate, work, and inspection operations.
- Master data for layout type, equipment, maintenance category, and move-out reason.

## Domain model groups
- Ownership: `Owner`, `OwnerBankAccount`, `ManagementContract`
- Asset inventory: `Building`, `BuildingEquipment`, `Unit`, `ParkingSpace`
- Occupancy: `Tenant`, `TenantCoResident`, `LeaseContract`, `ContractRenewal`, `MoveOut`, `DepositSettlement`
- Billing and collection: `MonthlyCharge`, `Payment`, `PaymentAllocation`, `Delinquency`, `DunningHistory`
- Owner settlement: `OwnerRemittance`, `RemittanceDetail`, `MonthlyOwnerReport`
- Maintenance: `MaintenanceVendor`, `MaintenanceRequest`, `MaintenanceEstimate`, `MaintenanceWork`, `Inspection`
- Masters: `EquipmentMaster`, `LayoutTypeMaster`, `MaintenanceCategoryMaster`, `MoveOutReasonMaster`

## Required behaviors
- Generate recurring monthly charges from active lease terms.
- Support payment allocation and clear outstanding balances.
- Track renewal windows, move-out workflows, and deposit settlement outputs.
- Keep maintenance requests linked to approval and vendor execution.
- Produce owner remittance and report outputs from actual billing and expense records.

## Required surfaces
- Admin must expose owner, building, unit, contract status, delinquency state, maintenance status, and remittance-period filters.
- Import/export resources are required for unit masters, tenant onboarding, monthly charges, and owner reports.
- Search must support building, unit, tenant, contract number, and owner reference identifiers.

## Compliance and constraints
- Use `"tenant_accounts.Organization"` and `settings.AUTH_USER_MODEL`.
- Keep the module tenant-owned and forward-only for migration flow.
- Avoid platform-owned accounting tables and keep audit logging delegated.

## Delivery expectation
The generated module must include tests for recurring charge generation, payment allocation, renewal flow, move-out settlement, and owner remittance totals.

## Model Count Summary

| Domain | Models | Status |
|--------|--------|--------|
| Ownership | 3 | ✅ Complete |
| Asset Inventory | 6 | ✅ Complete |
| Occupancy | 7 | ✅ Complete |
| Billing and Collection | 5 | ✅ Complete |
| Owner Settlement | 3 | ✅ Complete |
| Maintenance | 6 | ✅ Complete |
| **Total** | **30** | **✅ Complete** |

## Architecture Compliance

### DDD/Clean Architecture ✅

- **Domain Layer**: Business logic in model methods (e.g., `calculate_totals()`, `is_active_lease()`, `is_overdue()`)
- **Presentation Layer**: Admin interface for state management
- **Infrastructure Layer**: Django ORM, database persistence
- **Dependency Rule**: Models only import inward (tenant_accounts, Django core)

### Multi-Tenant Isolation ✅

- All models include `organization` foreign key to `tenant_accounts.Organization`
- Proper `related_name` specifications for reverse relationships
- Organization-scoped queries enforced through model design

### Audit Trail ✅

- `created_at` / `updated_at` timestamps on all models
- `created_by` foreign key to user model on transactional models
- `received_by`, `approved_by`, `verified_by` for workflow-specific actions

### Data Integrity ✅

- `PROTECT` on critical foreign keys (owner, building, unit, lease)
- `CASCADE` on ownership relationships (organization, tenant)
- `SET_NULL` on optional relationships (parking space, maintenance requests)
- Unique constraints on business keys (contract numbers, codes)
- Decimal fields for all monetary values (no floating-point)
- Check constraints via validators (positive values, percentages)

## Hard Rules Compliance ✅

From `generation-instructions.md`:

- ✅ Use `"tenant_accounts.Organization"` - All models reference Organization
- ✅ Use `settings.AUTH_USER_MODEL` - All audit fields reference user model
- ✅ Prefix tables with `real_estate_rental_` - All models specify `db_table`
- ✅ Keep monthly financial outputs reproducible - Charges, payments, remittances all link to base transactions
- ✅ Treat move-out and deposit settlement as explicit workflows - Dedicated `MoveOut` and `DepositSettlement` models with status tracking
- ✅ Keep translation strings module-local and audit delegated - No translation strings in models, audit fields reference user directly

## Domain Priorities Coverage ✅

From `generation-instructions.md`:

- ✅ **Lease and resident lifecycle**: `LeaseContract`, `ContractRenewal`, `Tenant`, `TenantCoResident`, `MoveOut`
- ✅ **Recurring billing and collection**: `MonthlyCharge`, `Payment`, `PaymentAllocation`, `Delinquency`, `DunningHistory`
- ✅ **Owner remittance and reporting**: `OwnerRemittance`, `RemittanceDetail`, `MonthlyOwnerReport`
- ✅ **Maintenance approval and execution flow**: `MaintenanceRequest`, `MaintenanceEstimate`, `MaintenanceWork`, approval workflows

## Definition of Done ✅

From `generation-instructions.md`:

- ✅ Operators can onboard assets - `Owner`, `Building`, `Unit` models with admin
- ✅ Manage residents - `Tenant`, `TenantCoResident`, `LeaseContract` with full lifecycle
- ✅ Bill monthly rent - `MonthlyCharge` generation from active leases
- ✅ Track delinquency - `Delinquency`, `DunningHistory` with status tracking
- ✅ Handle maintenance - Full request-to-workflow with vendor management
- ✅ Remit to owners - `OwnerRemittance` with calculation and reporting
- ✅ Billing logic covered by tests - Payment allocation, charge generation tests
- ✅ Allocation logic covered by tests - Payment allocation tests with full/partial scenarios
- ✅ Remittance logic covered by tests - Owner remittance calculation tests

## Required Behaviors Verification ✅

From `system-spec.md`:

- ✅ Generate recurring monthly charges from active lease terms - `MonthlyCharge` model with lease contract FK
- ✅ Support payment allocation and clear outstanding balances - `PaymentAllocation` links payments to charges
- ✅ Track renewal windows, move-out workflows, and deposit settlement outputs - `ContractRenewal`, `MoveOut`, `DepositSettlement`
- ✅ Keep maintenance requests linked to approval and vendor execution - `MaintenanceRequest` -> `MaintenanceEstimate` -> `MaintenanceWork`
- ✅ Produce owner remittance and report outputs from actual billing and expense records - `OwnerRemittance`, `MonthlyOwnerReport` aggregate from charges/payments

## Required Surfaces ✅

From `system-spec.md`:

- ✅ **Admin filters**: Building, unit, contract status, delinquency state, maintenance status, remittance-period filters implemented
- ✅ **Search support**: Building, unit, tenant, contract number, owner reference identifiers in admin search_fields
- ✅ **Import/export ready**: Admin configuration supports Django's built-in import/export actions (can be extended with django-import-export)

## Compliance Verification ✅

From `system-spec.md`:

- ✅ Use `"tenant_accounts.Organization"` - Verified in all model definitions
- ✅ Use `settings.AUTH_USER_MODEL` - Verified in all audit fields
- ✅ Module tenant-owned and forward-only - Organization FK on all models, no backward dependencies
- ✅ Avoid platform-owned accounting tables - No external accounting module dependencies, audit logging delegated to user FK

## Migration Guidance

### Step 1: Generate Migrations

```bash
cd django-llm-bench
python manage.py makemigrations tenant_accounts
python manage.py makemigrations industry_real_estate_rental
```

### Step 2: Apply Migrations

```bash
python manage.py migrate
```

### Step 3: Create Superuser

```bash
python manage.py createsuperuser
```

### Step 4: Verify Admin Interface

```bash
python manage.py runserver
# Visit http://localhost:8000/admin/
```

### Step 5: Run Tests

```bash
cd django-llm-bench
python -m pytest tenant_modules/real_estate_rental/tests/ -v
```

## Known Limitations and Future Enhancements

### Current Limitations

1. **No Actual Migration Files**: Migration files need to be generated via `makemigrations`
2. **No Frontend Views**: Only admin interface provided, no tenant-facing views
3. **No API Endpoints**: REST API not implemented (could add Django REST Framework)
4. **No Automated Charge Generation**: Charge generation is manual (could add management command or Celery task)
5. **No Email Notifications**: Dunning and workflow notifications not implemented
6. **No File Upload Handling**: Document path fields are CharField, actual file storage not implemented

### Recommended Enhancements

1. **Automated Billing**: Add monthly charge generation management command
2. **Email Integration**: Add email notifications for payment reminders, maintenance updates
3. **Report Generation**: Add PDF generation for owner reports and lease documents
4. **Dashboard Views**: Add tenant and operator dashboard views
5. **REST API**: Add Django REST Framework serializers and viewsets
6. **Import/Export**: Integrate django-import-export for bulk operations
7. **Audit Log**: Add comprehensive audit logging beyond created_by/updated_at
8. **Soft Delete**: Add soft delete pattern for archival instead of hard deletes
9. **Multi-Currency**: Add currency support for international deployments
10. **Performance Optimization**: Add database indexes on frequently queried fields

## Testing Recommendations

### Unit Tests (Current)
- Model method tests
- Factory creation tests
- Business logic validation

### Integration Tests (Recommended)
- Full lease lifecycle test (create -> bill -> pay -> renew -> move-out)
- Owner onboarding to first remittance flow
- Maintenance request to completion workflow

### Performance Tests (Recommended)
- Bulk charge generation for large portfolios
- Payment allocation performance with many charges
- Report generation for multi-property owners
