## Summary
- Adds **real estate** as a new account type (`real_estate`) for
tracking property assets within the existing Accounts page
- Properties store metadata (type, address, purchase price/date, area,
notes) in a dedicated `real_estate_details` table with a one-to-one
relationship to accounts
- Properties can be **linked to a loan account** (mortgage) to
implicitly calculate equity — property value counts as asset (+), linked
loan counts as liability (-)
- Market value is tracked as the account balance and uses "market value"
terminology throughout the UI
## What's included
### Backend
- `PropertyType` enum (Residential, Commercial, Land, Vacation, Other)
- `RealEstateDetail` model, factory, migration, policy
- `StoreRealEstateDetailRequest` and `UpdateRealEstateDetailRequest`
form requests
- `RealEstateDetailController` with `update()` for editing property
details
- Extended `Settings\AccountController@store` to create
`RealEstateDetail` when type is `real_estate`
- Extended `AccountController@show` to load real estate detail, linked
loan with bank info, and available loan accounts
- Extended `AccountController@index` SQL ordering to include
`real_estate`
- Conditional validation rules in `StoreAccountRequest` for real estate
fields
### Frontend
- New `real_estate` type in `account.ts` with `PropertyType`,
`AreaUnit`, `RealEstateDetail` interface, and helper functions
- Conditional real estate fields in `account-form.tsx` (property type,
address, purchase price, purchase date, area, linked loan, notes)
- `PropertyDetailsCard` component in `Accounts/Show.tsx` with view and
inline edit modes
- "Update market value" terminology in balance update buttons for real
estate accounts
- `real_estate` added to account type ordering and groups on the Index
page
- Wayfinder routes regenerated
### Tests
- 22 feature tests covering creation, validation, show page, index
ordering, updating details, IDOR protection, model relationships, and
soft delete behavior
- Unit test updates for `AccountType` enum (`reducesNetWorth`,
`isNonTransactional`)
### Translations
- 32 new Spanish translation strings for all real estate UI
## Design decisions
- Real estate accounts are **non-transactional** (like
investment/retirement) — balance-only tracking for now. Future iteration
will link transactions directly for rental income/expense tracking
- **Single loan per property** via direct FK from
`real_estate_details.linked_loan_account_id`
- No encryption on address/notes fields (opted out per discussion)
- No separate sidebar page — real estate is a grouped section within the
existing Accounts page
