Yanushi is a property management application designed for landlords who value simplicity and visual excellence. Built with Ruby on Rails 8 and styled with Tailwind CSS and daisyUI, Yanushi provides a streamlined experience for managing rental properties, tenants, and finances.
- 🏠 Property Portfolio: Manage all your rental properties in one place with detailed occupancy and financial summaries.
- 👥 Tenant & Lease Management: Track active leases, tenant contact information, and automated rent schedules.
- 📊 Unified Financial Ledger: A centralized view of all property-related transactions, including scheduled rents, payments, utility bills, and maintenance expenses.
- 💸 Automated Document Ingestion: Upload Chase bank statements or Venmo receipts, and Yanushi will automatically parse, extract, and match payments to your tenants.
- 📑 Tax Reporting: Generate year-filtered summaries designed to make filing Schedule E of Form 1040 simple and stress-free.
The property ledger provides a unified view of all financial activities, automatically categorizing and color-coding items for quick scanning:
- Scheduled Rent (Blue): Expected rent payments automatically generated based on the active lease terms. Indicates if a rent is Paid, Unpaid, or Overdue.
- Tenant Payment (Green): Confirmed payments received from tenants. Automatically zeroes out the corresponding scheduled rent and contributes to the property's income.
- Expense (Red): Property maintenance costs, repairs, or utility bills. Reimbursable expenses are clearly tagged.
- Tenant Charge (Yellow): Any charges passed onto the tenant (e.g. late fees, utility reimbursements).
Yanushi eliminates manual data entry by automatically parsing bank statements and payment receipts.
Navigate to the Payment Ingestions page and upload a supported document, such as a Chase checking account statement or a Venmo receipt.
Once uploaded, Yanushi extracts the transactions and automatically matches them to your active leases based on payer name, tenant name, or rent amount. You can review and confirm these matches in the Review Queue.
Once confirmed, the payments instantly appear in your property's Financial Ledger. Overdue scheduled rents are automatically resolved and your property's financial totals are recalculated in real-time.
While automated ingestion is recommended, you can also record payments manually if a tenant pays with cash or an unsupported method.
From the property ledger, click the "Record Payment" button next to any scheduled rent. A modal will appear, allowing you to enter the payment date, amount, and a transaction reference.

Yanushi uses RBS and Steep for gradual static type checking. Hand-written application signatures live in sig/app/, local shims live in sig/shims/, and generated Rails signatures live in sig/rbs_rails/.
Run the type checks locally before opening a PR:
bundle exec rbs validate
bundle exec steep checkWhen adding or changing typed application code:
- Add or update the matching RBS file under
sig/app/. - Add new source files to the
checklist inSteepfile. - Keep
untypedat Rails or third-party gem boundaries where precision is not worth the maintenance cost. - Re-run
bundle exec rbs validateandbundle exec steep check.
After schema migrations, regenerate Rails-aware signatures:
bin/rails rbs_rails:all
bundle exec steep checkAfter gem updates, refresh third-party signatures:
bundle exec rbs collection installSee sig/README.md for signature ownership, shim conventions, editor setup, and known limitations.
