It would also have to be put up and taken down between each tenant and I don't know how responsive your PM will be to this extra work. 

She's not going to have any leg to stand on in court if you get that far unless there's some explicit language prohibiting the owner from assigning responsibilities to another legally authorized party, and I'm guessing there isn't if another PM company was maintaining the lease and provisions - and the fact that the tenant was voluntarily working with the other PM confirms the acceptance of an authorized agent even if it's not explicitly stated, the same way if you accept rent from a tenant after a lease expires you imply acceptance of the lease terms continuing (which is why you should always have a holdover provision). 

I think your questions are a bit to general and you are going to get even more general responses.

I read Pamela's response in January 2025!

Looking forward to the responses on this!

Quote from @Rick Ilich: Thank you very much for the quick response!

@Donald Hatter thank you for the responses and offer.

Another option is to co-sign but that has the same impact on my credit and responsibility to the bank.  

Thank you for your response, Mike.

Andy  Appreciate the response, Andrew.
