Would this just be a lease addendum?

[Linda Thomas]

Hello all,

Tenant just moved into the property 4 days ago and now claims that significant other just arrived from South America and would like to add them to the lease. Would you require a rental app, pay rental fee, run all the background checks etc? or just do a lease addendum for the additional person and just add them to the current lease? I just kinda find it odd and fishy with the timing of this all? perhaps I am reading too much into it. Looking for suggestions on the best way to handle this situation and perhaps what questions I might need to ask.. thanks in advance !
