Co-signer on lease in Pennsylvania

[Linda Thomas]

Hey BP,

I think having a co-signer is allowed in PA. How would I know for sure and how would I know what things apply or do not or not allowed to have per law. Nathan shared a cosigner form which is a great help but I just don't know if I might get into some pickle because I"m not familiar with having a co-signer? are there certain laws/rules i need to look up/ follow? Can it ever be declared null/void what cosigner signed??

Looking for insight before deciding to move forward with this as it is all new to me. 

Thanks,
