After the initial fixes and repairs we had to do during the purchase process (every home in California has termites), I've been working to automate as much as possible. Here's my "Landlord Stack":
1. Cozy for applications and rental payments (https://cozy.co/) (Price: free)
2. Rocket Lawyer for leases, other documents, and random law questions (https://www.rocketlawyer.com/) (Price: $50/mo)
3. Xero for accounting (https://www.xero.com/) (Price: $9/mo)
4. Trello for organizing information and to-dos (https://trello.com/) (Price: free)
5. We bank at Chase and use their online bill-pay to handle the few utilities we're responsible for.
So for I've had to unclog a couple toilets and fix a window screen. Other than that, smooth sailing so far. Email in profile if you want to get in touch.
