Question: An owner calls up and says, "I want to put a storage building on the rental house that you handle for me. Please tell the tenant that I will be doing this."

Your Professional Landlord's answer. I will be more than happy to contact the tenant and make sure this is ok with them. Remember they have  leased the property and have all rights to it. They will need to give you permission to do this.

Question-Tenant wants to pay 1 year in advance on the rent and get a discount for doing this. Can you do it?

Your Professional Landlord's answer. You can but probably will not want to do this. You are at extreme risk by doing so. First it is harder to get the tenant out if there is a problem. Second, you do not want to pay the owner because if there is a problem and you have to refund the money then you have to go back to the owner who may or may not be willing to give you the money back or worse the owner is in foreclosure.

Question- House is leased and the owner of the home goes into foreclosure. Is tenant's lease still valid?

Your Professional Landlord's answer. No. The tenant has no rights and the lease is not valid.
