Leases have come a long way over the past few years. In the past, they were hard to read, hard to understand, and hard to enforce. Your state may or may not enforce a “Plain language” lease. Even if it doesn’t, I encourage you to write a lease that is easy to understand by everyone.
There are many good leases available on line that are safe. You can also take one of those and adapt them if you want something a little different. If you are going to change it, make sure what you are writing is legal and enforceable. Just because you write “Landlord can throw the tenant out of the house without notice” doesn’t mean that you can do it! You still need to abide by your state’s and local legislation.
A couple notes on plain language: All information should be clear. Use headings, short sentences, short paragraphs, and have everything in good order. A good test: Let a child read it. If they understand it then it is probably clear enough. 2nd, let a lawyer read it.
A good lease will help you enforce your rules and get a bad tenant out. It will not help you avoid a bad tenant.
