See the full picture across your rental portfolio.
Every maintenance request, vendor invoice, and lease update is a data point about your rental properties. The average portfolio generates ~94 emails per property per year. They often have many of the same issues, water heater needs to be replaced, make-ready expenses, so it becomes hard to keep the details straight by just reading emails. We had that problem ourselves, which is why we built The Control Surface, to assemble all the emails into logical cases, timelines, and cost records so the full picture is always there when you need it.

Tax season arrives
You need repair costs and vendor payments, but they're buried across hundreds of emails.
A repair request gets buried
Your property manager sent an update three weeks ago. You read it. But the follow-up never came, and you didn't notice.
A partner asks questions
"How much did we spend on that roof?" You know the answer is somewhere in your inbox.
You're switching property management companies
You need the full history before the transition: every vendor, every open item, every cost.
