I don't disagree with your words, but keep in mind that some people don't view it as a business. Eventually they'll raise it as their mortgage raises and/or they sit down one day, calculate their costs and actaully look at their ROI. Some could take years to come to that realization. Some are accidental landlords (something I think we're seeing much more of today) and are happy to just cover the mortgage and mx items because it's a "long-term" investment. I'd wager that you see more of these types who how a single, SFH.
