8 free tools for rental owners, managers and agents
Eight free tools for rentals that run in your browser: a yield calculator, an owner report, a listing builder, message templates and more. No sign-up.
By the RentalThread teamHow we write our guides4 min read
You can now use eight free tools for rentals on rentalthread.com/tools. Each one does a single job: work out a property's yield, prepare the monthly report for an owner, write a listing, plan a year of maintenance. They run in your browser, they need no account, and nothing you type is sent to us.
The RentalThread app isn't open yet. We made these tools while we build it, around tasks that fill an owner's, manager's or agent's week.
Why free tools before the app
Most of the work around a rental happens in small, repeated tasks: a rent reminder, a report for the owner, a listing for a new tenant, a spreadsheet at tax time. You probably do them by hand every month, often from a blank page.
Each tool takes one of those tasks and gives you a result in a few minutes, from the facts you type in. There's no AI in them. The numbers come from formulas shown on the page and the texts from fixed templates you can edit, so you can see how every result was made.
The eight tools
For owners
- Rental yield calculator: gross yield, net yield before loan payments and monthly cash flow for one property, with the formulas. The full version compares up to three properties or scenarios, tests empty months and rent changes, and adds loan math.
- Rental income and expense spreadsheet: a ledger with fixed categories and a rent row for each month, as a CSV file for one property. The full version is an Excel workbook for up to 10 properties, with monthly totals worked out by formulas and totals by category for your accountant.
- Rent comparison worksheet: the median and range of the rents you found nearby, and a starting range for your unit. The full version takes up to 12 comparables, puts free months and required fees on the same basis, and shows your adjustments line by line.
For owners and property managers
- Preventive maintenance calendar: a 12-month maintenance plan for one rental, with who usually does each task. The full version gives you a calendar file for Google Calendar, Apple Calendar or Outlook, with a reminder a week before each task, for up to 10 properties.
- Owner report: a monthly summary for the owner with rent received, rent still owed, expenses, repairs and approvals, ready to copy into WhatsApp or email. The full version handles up to 30 units and several owners, and prints a report with your name and logo that you can save as a PDF.
For real estate agents
- Rental listing builder: a listing description built from your facts, plus the facts it still needs. The full version writes four texts (the description, a WhatsApp message, a social caption and a reply to the first inquiry) in English, Spanish and Portuguese, and prints a flyer with an optional QR code.
- Viewing slots message: your free hours cut into lettered visit times, in one message ready to send. The full version covers up to seven days and five listings, and gives you a calendar file that holds the times in your own calendar.
For everyone
- Rental message templates: clear, polite messages for rent, repairs, visits and inquiries, ready to copy. The free version has the six most common ones; the full version has all 24, in any language, with a friendly or firm tone.
Free and full versions
Every tool has a free version that works for everyone, without an email. The full versions are free too. To unlock them, join the waitlist with your email and confirm it. The full versions open on that device as soon as you confirm. You won't need a card or a payment.
What happens to what you type
The tools run in your browser, and what you type isn't sent to us. When a full version saves your inputs, they stay in that browser, and "Clear my data" removes them.
The results are drafts and estimates from what you enter. They're not financial, tax, legal or real-estate advice, and rules differ from place to place, so check the ones where the property is.
How the tools connect to RentalThread
The tools work from what you type each time. RentalThread will do the same jobs from each property's own records, with everyone involved in the same place. Some of what we're planning:
- Monthly statements for owners, built from the rent, expenses and repairs already recorded.
- Recurring maintenance with reminders, and repairs that the tenant, the pro, the owner and the manager follow in one thread.
- Tenants booking their own visits from one link per listing.
Joining the waitlist for a tool also gets you early access to RentalThread when it opens, in waves. If there's a tool you'd like us to build next, write to us at contact@rentalthread.com.
Send it to an owner, manager, agent, tenant or pro who could use it.
