Two homes, a rental, the lake place — and a different spreadsheet for each one, none of them current. The Multi-Property Edition puts the whole portfolio in a single dashboard: every property's systems, schedules and costs, plus a rollup of what's due and what you're spending across all of them.
Just one home? → The Home Operations System
One property is a system. Several is a portfolio — and a portfolio managed as scattered parts quietly bleeds money: the missed service on the rental, the lapsed warranty on the second home, the repair you forgot to deduct. The fix isn't more spreadsheets. It's one brain that sees everything at once.
It's the full Home Operations System — systems, seasonal schedules and repair logs — replicated cleanly per property, with a portfolio layer on top that rolls everything up.
Add every home and rental — label, address and type (primary, rental, vacation, flip). Switch between them in a click; each property carries its own status flag so you can see trouble at a glance.
Unlimited propertiesThe view you can't get from spreadsheets: a Due Soon rollup across every property for the next 60 days, plus a cost rollup showing spend by property and across the whole portfolio, with a year filter.
Everything, at onceEach property gets the complete toolkit — Systems & Appliances with auto-calculated next-due dates and status flags, the four-season maintenance schedule, and a repair & cost log with annual totals. All scoped to that property.
Nothing stripped outFor every property, a dedicated notes space for the things landlords actually track — lease dates, tenant contacts, rent, per-unit specifics. The operational detail that never fits in a maintenance app.

It's the same engine, built for many properties instead of one. You get the full Systems / Seasonal / Repairs toolkit per property, plus a portfolio dashboard that rolls up what's due and what you're spending across all of them — and landlord tenant/unit notes. If you only have one home, the Home Operations System ($37) is the right fit.
