Questions & Answers

As answered by people managing UnitDocs and RentMaster.

What makes your product unique?

UnitDocs's answer

UnitDocs has a Tenant Timeline โ€” a feature no other landlord tool offers. It gives you a single chronological feed of every event across all your units: rent payments, repairs, move-ins, move-outs, and inspections. When a tenant disputes something or the CRA/IRS audits you, you can find exactly what happened in seconds, not hours.

Unlike full-featured property management platforms, UnitDocs deliberately does one thing really well: keeping all your rental records organized and instantly searchable. No bloat, no complexity โ€” just your docs, expenses, and tenant history, always at your fingertips.

Why should a person choose your product over its competitors?

UnitDocs's answer

Most competitors are built for professional property managers with 50+ units, and come loaded with rent collection, tenant screening, accounting, and maintenance ticketing. That's a lot of complexity for a DIY landlord with a few units.

UnitDocs is built for a different use case: staying organized. If you're tired of hunting through Gmail for a lease, digging through your phone for a repair photo, or scrambling at tax time for receipts โ€” UnitDocs solves exactly that.

  • Simpler: No learning curve, no setup complexity
  • Cheaper: Free for up to 3 leases, $9.99/month for up to 50
  • Focused: Does one thing really well instead of many things poorly
  • Tenant Timeline: No competitor offers a chronological event history per unit
  • Free forever plan: Genuinely free, no credit card required

How would you describe the primary audience of your product?

UnitDocs's answer

UnitDocs is built for DIY landlords โ€” individuals who self-manage a small number of rental properties (up to 50 units) without a property management company.

Typically: - Individual landlords with 1โ€“10 rental units - Small-scale real estate investors managing their own properties - Landlords in Canada and the US who need to stay organized for tax season (CRA/IRS) - People who currently manage documents through email, Google Drive, phone photos, or a shoebox - Anyone who wants a simple, affordable alternative to bloated property management software

What's the story behind your product?

UnitDocs's answer

UnitDocs was born out of a frustration that every DIY landlord knows well: your rental documents are scattered everywhere โ€” leases buried in email, receipts on your phone, inspection notes in a random folder, and repair invoices somewhere in a shoebox.

When a tenant dispute arose or tax season hit, finding the right document was a stressful, time-consuming hunt. Property management platforms existed, but they were designed for professional managers with large portfolios โ€” bloated, expensive, and overkill for a small landlord.

So UnitDocs was built: a focused, simple tool that puts your docs, expenses, and tenant history in one place. The goal was never to build another all-in-one platform. It was to solve one problem really well โ€” organization โ€” for the millions of landlords who just need to stop losing things.

Which are the primary technologies used for building your product?

UnitDocs's answer

UnitDocs is a web-based SaaS application built on modern, enterprise-grade infrastructure:

  • Authentication: Auth0 (enterprise-grade authentication)
  • Cloud Hosting: Enterprise cloud infrastructure
  • Security: 256-bit encryption in transit and at rest
  • Email: Resend
  • Frontend: Modern web technologies (React-based)
  • Storage: Secure cloud file storage for documents, photos, and videos

Who are some of the biggest customers of your product?

Some of our users include: - Individual landlords in Toronto, ON and New York, NY managing small multi-unit properties - Small-scale real estate investors who self-manage their rental portfolio - First-time landlords looking for a simple, organized way to manage their documents and expenses
