About this app

Landlord Notebook is an easy-to-use management app for landlords who manage rental properties independently.

"Have I received all the rent this month?"

"How much revenue is this property generating annually?"

"When does this tenant's contract expire?"

"When was the last repair done?"

You can check all those daily "little things that landlords are curious about" with just your smartphone.

■ The biggest feature: Data accumulates without manual recording

Once you register your property, room, tenants, loans, and fixed costs, the app automatically accounts for payments as they arrive. There's no monthly input required.

If the amount is different for a given month, you can correct only that one entry. Corrections won't overwrite the next month's record. Deleting unnecessary records keeps them permanently gone.

When you revise the rent, it's recorded in the history, so you can even look back and see "how much it was in April of last year."

Recommended for landlords like these:
* Own a house, apartment building, or condominium unit
* Started rental business with a small number of properties
* Manage rent and expenses using Excel
* Check income and expenses using paper notebooks or bankbooks
* Entrust management to a management company, but want to understand income and expenses yourself
* Want to check the profitability of each property more easily
* Want to organize annual income and expenses for tax filing
* Want to make being a landlord easier

Main Features

🏠 Property and Room Management
Manage everything from property information to individual room information. Occupancy rate and total rent are visible at a glance.

👤 Tenant and Contract Management
From move-in to contract renewal, move-out procedures, and security deposit settlement. You can also check the history.

💰 Rent and Income Management
Record rent and common area fees for each room. You can understand the income for each property while viewing the payment status.

📊 Automatic Income and Expense Organization
Record expenses such as repair costs, property tax, and insurance premiums. It automatically compiles monthly and annual income and expenses, so you can see "how much you ended up with."

Loan repayments are recorded separately for principal and interest. Only interest is a deductible expense, so you can use it directly when filing your taxes.

🔔 Reminders
Get notified when property tax payment deadlines or fire insurance expiration dates are approaching. Prevents you from "missing the deadline."

🧾 Data Backup
You can export and import data. When changing devices, you can transfer data between iPhones and Androids.

📋 CSV Output for Tax Filing (Premium)
You can export a year's worth of income and expenses, separated into income, deductible expenses, and non-deductible expenses. For those filing blue-form tax returns, you can also output in the form of a journal with debits and credits, which can be used for importing into accounting software or handing over to a tax accountant.

📈 Graphs and Asset Management (Premium)
Check monthly and yearly income and expenses in graphs. You can track your current net worth and its trends based on property value and loan balance. You can also simulate cumulative cash flow trends, return on investment, and depreciation.

Records are stored only on your device.

Property addresses, rent, and tenant names are all stored on your device. They are never sent to our servers.

However, migration is required when changing devices. Please use the backup export and import functions.

Pricing

The free plan allows you to use all the basic management features for one property. It includes income and expense recording, tenant management, history, reminders, and backups.

The premium plan removes the property limit and provides automatic updates for all properties, CSV output for tax filing, various graphs, and depreciation simulations.

Even if you cancel your subscription, your registered records will not be deleted.

Enjoy "Rent Received" even more.
