Free 5-year forecast

Know which unit is about to cost you.

Every rental's systems, repairs, tenants, and pros in one record. Start with a 60-second forecast for one rental, then add the rest.

What you'll see
  1. What's likely to go first

    The system closest to the end of its typical life, and roughly what it costs to replace.

  2. What the next five years add up to

    A total range, so a $9,000 year doesn't arrive mid-lease.

  3. What you don't know yet

    The gaps in the unit's history, which is the part that costs you most.

What will this rental cost you?

Start with two quick answers. You can add what you know about each system after.

A best guess is fine.

  • Roof
  • Heating
  • Cooling
  • Water heater
About how big is it? (sq ft, optional)

Enter the year your rental was built to continue.

Most rentals run on texts, spreadsheets, and memory

It works until a tenant, an accountant, or a contractor needs an answer you don't have.

Structure remembers all of it, so you don't have to.

Every portfolio has a schedule of expensive surprises

See what's coming across every unit, so repairs happen between tenants instead of during them.
