Tenant wants niece to move in

[Tony Murphy]

We've had a fairly good tenant (single mom with 14 yr old) renting out an apt in our duplex for the last two years.  I got a call that she wants her niece (18yr old) from Texas to move in short term for a few months until she gets her feet on the ground.  She gave me the whole story i.e. moved here to be with a boyfriend, broke up, she's a great kid, etc.  My tenant pays fair market rent already (in fact a little more since rents have gone down slightly in the area) so I'm wondering if I should still ask for additional money each month to at least cover the increased cost (water/sewer, etc).  I also plan to have her niece go through my screening process and fill out her own lease.  Am I missing anything else?

@Tony Murphy , If the tenant has lived in the property for X days (as defined by your state's landlord tenant laws) then regardless of whether or not they're on the lease, they have rights. Especially if you know about them being there.

Read your landlord tenant laws regarding eviction.
