Renting out a house is a service. Being a landlord means legal responsibilities and liabilities. Houses need to be up to code, maintained, insured, and this is expensive. Grass needs to be cut, pipes need to be fixed, appliances need to be in working order. The person who wants to rent a house has obviously chosen not to, or cannot afford to, buy a house. They get the upside of having to take no financial risk, ie. fire, tornado, flooding, economic/housing market collapse, etc. The downside is they do not have ownership and make no market gains.
