Your tenant will have a better view of you as a landlord and as a result, reciprocate in treating your unit right and paying on time.

The purpose is to verify that the rent amounts stated in rent rolls are current and accurate, that the security deposit amounts to be transferred at closing match what the tenants have provided, that the number of occupants/ pets etc. in the unit match what’s in the lease, and that there are no other “side agreements”/ verbal or handshake agreements between the tenants and current owners/their representatives.
