Help finding best software for tenants rent and lease

[Allison Cutlip]

Hi all, My boyfriend and I are buying our first home that is a duplex, planning to live in one unit and rent the other side. House hacking, if you will. There are tenants in the other side already so we will need everything solidified for them by the time we get the title and we are set to close, which is February 19th. We plan to keep them on a month to month lease but after a few months, have them sign a year lease and increase rent, however, we need help finding a GOOD app/website to get lease agreements/documents from or get a template so we can fill/add certain things we want. We need to find a good app/website for them to send rent as well, preferably one that has many things built into it, making it more simple to manage things in one place. If anyone has recommendations for what they've been using and like, we would appreciate it greatly as well as any tips you may have for us!

Thank you!
