Provisions to protect self and property in lease terms

Hello everyone,

I am currently living in a house and plan on renting out the rooms to help cover the cost. Eventually i plan on moving out and renting out the whole house for a rental property.

I would like some input on what seasoned landlords put in there lease to protect and minimize risks such as damage, delinquent payments and other problems. Also if you have ever rented out rooms in your house and have advice ill take it! 

I have a lawyer to go over the lease agreement but would like to have an idea of what i want in it before i see her to avoid more time with her(AKA spend more money)
