Individual in group lease not paying rent

[Justin Metzler]

So I have been leasing my rental home to a group of 4 young professionals for about 10 months now. They have been paying on time but for the last two months, one of them has not been paying the rent. They have however as a group been paying me the full rent which is great. The group would like to allow this individual to stay until the full year is up so he can find a place to live. However, they do have someone additional that would like to move in and take the place of the delinquent renter which would be five individuals in the home until the end of July. Has anyone had a similar situation and is it best to leave it to the group to work it out? I live in Ohio so not sure if legally, it makes a difference on landlord rights. Any thoughts are appreciated.
