I self-manage a small portfolio and the hardest part of preventative maintenance hasn’t been remembering what to do — it’s coordinating people.Specifically:Vendors operate on schedules, tenants operate on availabilityRoutine servicing (filters, HVAC, inspections) easily slips when no one “owns” the coordinationVendor info, service dates, and unit details end up scatteredCalendars exist, but they don’t reflect what’s actually happening at the unit levelI ended up building a tool for myself that centralizes:Properties and unitsVendors and the services they provideEquipment tied to each unitA shared maintenance calendar that reflects routine servicing, not just repairsIt’s essentially finished, and before rolling it out further I’m looking for a few landlords who already care about preventative maintenance to pressure-test the workflow:Does this actually reduce back-and-forth?

Take a photo, then manually enter all the data about your transaction right then.

I'm into STR investing, and to analyze deals, I use AirBnB and Vrbo real booking data.

No rent roll or historical utility data provided yet. 

NAR pulled their data on ADU valuations yesterday on the premise of the data being old.  

Boats need a lot of maintenance and trailers also need some maintenance as I got the hard lesson last week.In Ca we now have boat license required (none was required when I had the pen yan) but it does not include any skills test (it is online, you watch a segment then take a test on that segment).  

Taxes, insurance, debt service, and closing costs don’t care which unit you live in.One thing I’d add that’s often missed: when house hacking, I always stress-test the deal assuming you move out in 1–2 years and it becomes a full rental.If it still meets your minimum DSCR and cash flow targets as a full rental, it’s usually a solid house hack.

You could signup for the free part and test it out.

We've got the data to back all this up, do you?

This will test if your investment model gets you there, along with your personal savings.7.
