Agreement Checklist
You should probably print this out and check off the items one by one as you get them signed with the tenant.
It reminds you that you should explain the rental agreement to the tenant. Once you hand over the keys, the agreement may never be thought of again. If there are house rules, this is your last chance to make sure they're okay with them.
Note that the best time to protect your plaster walls is when you hand over the keys. Give out a package of wall anchors. Show them how to use them (or better yet, offer to hang pictures for them). Otherwise you're increasing your chances of vertical tears and broken chunks.
