Yeah, it's fun to hate on landlords but often they're not making much outside of appreciation - or they're basing their profit on renting a house today purchased ten or twenty years ago (which would be better to sell and do something else with the money, often).

I think the fundamental issue is that the whole renting market is buying long and selling short (buy a dwelling for a long period, rent it for short periods) and that causes issues on one or another direction (either you rent for what appears "too much" because you need to build reserves, or you rent for what appears "fair" and the first major expense kills the landlord).
