It is not useful to individualize this. Even if you could make a solid argument that being a landlord might sometimes take more effort than working a job does for someone else to pay your mortgage for you, corporations holding many properties at once (with just a couple of companies holding up to 5% of the rental stock) are going to have a bigger economic impact on the market, and the small-time landlord's experience isn't really relevant to that, vis effort, risk, or graciousness to their lessees.
