Existing tenant seeking to add occupants to her lease

[Emmanuel Sanchez]

Hello,

We recently had our first tenant move in after Labor Day weekend! Earlier this week, she asked about adding two occupants to her lease. Currently as is, there are five people (one adult and four kids/teens) living in the house (4 beds/2 baths/2 car garage/1,828 sqft.). The occupants she is seeking to add are two females (one adult and one teen). Seems like it may be family, but we are unsure how to proceed. If we decide on "yes," we would definitely require the additional adult occupant to submit an application. Should we raise the rent? Thoughts on the amount of people in a house of this size? Would really appreciate any insight on how to approach this

Thanks!
