Not an expert here but one thing I've noticed is that large / corporate landlords prefer to let a property sit empty rather than reduce the rent as supply/demand theory would indicate. My understanding is that this is because there are special tax benefits like you can write off the loss to lower your tax burden. How does this factor in?
