Duplexia automatically splits income, expenses, and valuation across units — so owners of 2-4 unit properties stop reconciling spreadsheets and start seeing real per-unit numbers.
Owners of 2-4 unit residential properties sit in an awkward middle ground — too small for enterprise property-management software built for hundred-unit portfolios, too complex for a single spreadsheet once you're splitting utilities and tracking multiple leases.
We're building AI tooling that handles the specific, repetitive complexity of managing a handful of units — not a single-family rental, and not a large portfolio.
The same complexity shows up on the tenant side, too — rent collection, maintenance requests, and routine questions end up scattered across texts, calls, and email, per unit, per tenant.
Add your duplex or small multi-unit property in a few minutes — no complicated onboarding or enterprise setup.
Income, expenses, and utilities are divided per unit automatically, so you always know real per-unit performance.
See valuation estimates, rent benchmarks, and compliance reminders in one place — updated as new data comes in.
Automatically split income, expenses, and utilities across units so you can see real per-unit performance.
We continuously monitor nearby rental and sale prices, so your property's estimated value and rent potential stay current — not a one-time number.
Keep multiple leases, renewal dates, and local multi-unit compliance requirements in one place.
Designed for owners with one to a handful of 2-4 unit properties — not enterprise portfolios.
Rent collection and tenant communication shouldn't live in five different apps. Duplexia gives every unit a single thread — with an AI assistant handling the routine parts.
Message tenants directly from Duplexia — no juggling texts, emails, and calls across units.
Tenants pay rent through a secure portal, with payments automatically reconciled to the right unit.
An AI assistant handles routine tenant messages — maintenance requests, reminders, FAQs — and loops you in only when it matters.

Fannie Mae and Freddie Mac treat 2-4 unit residential as its own financing category, distinct from single-family and large multifamily.
Tools that once required enterprise software budgets are now feasible for owners of a handful of units.
Property management platforms are built for large portfolios; spreadsheets don't scale cleanly past a single unit.
