additional tenant that adding to the existing lease

[Vicheka Chres]

Hello BP, 

I'm renting out this single family home to (currently) five individual tenants. One of them vouch for the additional tenant. I modified the lease to add the last tenant move-in date to Nov 1st but I haven't yet receive everyone's signature. So far I got three out of six signatures. Would this be a problem? If so, do you any suggestions of how I should fix this? 

Any advices and suggestions are appreciated. 

Thank you :)

You don't need to sign a new lease with everyone. The new tenant can be added with a hand-written note on the existing lease:

"On November 1, 2018, I authorized John Smith to be added to the lease. He has been given the opportunity to review the lease and agrees to the terms and conditions."

The have him sign it and you sign it.
