How to handle a Lease renewal. Sign new Lease or extension?

[Cam Jimmy]

Hello, I've only done this once before and I feel I am really over thinking this. One of my existing tenants is wanting to sign another 1-year lease. What is the best way to handle this? Should I print up a brand new lease  and call it the 2nd year lease, and add any changes? Or should I print up a lease extension and note the new changes on there and have them sign that? I feel like a have a ton of knowledge in every other aspect of my rental business but realize I have no clue what other people normally do in this situation lol. How do you guys usually handle this?
