Is there any problem with having a co-owner on the title/deed sign a lease agreement?

Some years back, a co-worker of mine found someone checking her mailbox out by the curb, then walking to her back yard on the way home from work.

We purchased several units that are in a Co-Op style property.

Neither the other co-owners, nor the sponsor, nor the manager may advance funds to a co-owner to meet expenses associated with the co-ownership interest unless the advance is recourse to the co-owner (and, where the co-owner is a disregarded entity, the owner of the co-owner) and is not for a period exceeding 31 days.The co-owners must share in any indebtedness secured by a blanket lien in proportion to their undivided interests.Distinguishing a Partnership From Co-Owners of Leased PropertyIn the case of property to be purchased by more than one equity investor and subjected to a long-term triple net lease, it may be possible for each equity investor to structure its participation as a purchase and lease of an undivided interest in the property, separate from the other equity investor's transaction, so as to preserve arguments that the equity investors are mere co-owners.

We require a 550+ credit score as well as a current job paystub or a co-signer who meets these requirements.

MAYBE it’s a co-op like what they use for buildings in new york?

Should I agree and 1) put them both on the lease or 2) put them both on the lease and make the one with more income sign a co-signer agreement?

@Troy Forney Here is an interesting perspective I heard from a co-worker who is a lender who has much more experience than me and has seen a few cycles.

Also, have you considered a co-signer?
